@@seisoloumano The 8568 came after Bil left Commodore, so I doubt he can answer that... but yeah... it would have been good if they had added support for that. How much it saves really depends a lot on what code is doing with vdc. What it especially allows is making efficient use of VDC's copy and fill acceleration without having to poll VDC every so often to see if it is done yet, and it could allow much easier syncing to vblank without wasting lots of cpu time on waiting for that.

Great video! Enjoyed it. I went from a VIC20 to a C64 breadbin to a C128 and still have all my original computers along with original drives and software including both GEOS 64 and 128. All still work. For the C128 I have a 1571 and a 1581. I not only continued playing my C64 games on it, being a teacher and taking classes to obtain my Masters degree, I used it write papers, type letters, make my own educational materials (study guides, worksheets, puzzles, etc.), print banners and signs, and a monthly newsletter for our local education association. The C128 was a great computer!

I've always felt that Geos 128 with a REU and a 1581 was every bit as good as a Mac of the era for a fraction of the price. I used mine up through the late 90's for running a small business. The monitor got flakey and that was why i finally sold it. Now I wish I had another. I'd upgraded the video ram to 64K, maxxed out the RUE to 2 meg, and had a 1571 as well as a 1581 to help GEOS be all that it would be. The 1531 mouse and 1801 monitor rounded out the setup. I also had a swiftlink for BBS usage until they faded away in the late 90's. It certainly was a great system!

Growing up with a commador 64 in the 80's I bought a used 128 for $500 CAD in 1990 than bought an AMD 386 DX40 in 1992 for $1200 CAD in Toronto. I was a little behind the curve, but that 386 sure beat the pants off the 128.

The 128 is the best of the 8bit era. I had one and I loved it.

I owned a 128 back these days with almost all Hardware options, including the 1581. I even hat a graphics extension from a Swiss company that provided real high-res… I don’t exactly know what the name of this option was. Well, now looking back i have to say the 128 flat was and still is the most beautiful homecomputer - not ignoring the Apples of that time.

Thank you for the video! I remember going to London with my mom in 1985, where she bought a ZX Sinclair Spectrum+ for me. But, by 1987, I was literally drooling over the C128, and loved the idea of it having 3 CPUs in one unit and being able to do so much. But it wasn't meant to be. My friends started buying Amigas in the late 80's, and I got a PC XT clone for my 15th birthday. I do remember seeing one of these C128's in person for the first time in 1991. It was in our high school computer lab, and we were doing assignments in Turbo Pascal on it. It was on its way to being outclassed by the PC's that were starting to replace it, but I thought it was so cool that it was still able to run Borland's Turbo Pascal via CP/M mode, and I recall that it ran it quite respectably :).

Amiga case designs were apparently based on C128. Even the C128D and desktop Amigas look alike. That was a good choice, since similar keyboard ergonomy design was still there until late 90's and modern mechanical keyboards seem to emulate this somehow.

The 128 was the perfect machine for me. Build in machine code monitor, powerful basic, practically dual heal setupand so on. I had a 128D in a metal case with 64k VDC ram, an REU with 256k extra ram, 1581&1571 external drives and all the stuff. I would just start writing programs, never knowing where it would take me. When i got my first IBM compatible i just used it to run TASM and a homebre transfer program for centronic -> userport. i think it was until 1999 when i gave it all away, that i would spend nights on end tinkering. Fond memories.

What crippled performance for CP/M on those home computers was the lack of a terminal. Just recently I ported CP/M 3 to a Z80 SBC and the terminal code is by far the most complex part of it. Usually a CP/M system would just send a character to the serial port and be done with it. But when it has to be it's own terminal, it has to keep track of screen coordinates, handle control codes, translate Screen coordinates to VRAM addresses and so forth. There is a huge amount of overhead just controlling the screen.

After finding this channel, I have enjoyed watching several of your videos. I do have one suggestion/request. The simulated screen borders you use, while looking nice, have the effect of shrinking the video output being displayed. The shots without an added border are much easier to read in my opinion.

That commercial for the machine was incredible. Very convincing!

I was clueless back then. Didn’t know anything about compatibility and I wanted to play C64 games,. I bought a C 128 and thank God it was compatible with the C 64.

I had the Commodore 64, then the Commodore 128 and after that the AMIGA. The best programming experience gave me the Commodore 128 BASIC 7.0 - and because of that I just ordered a Colour Maximite 2, but that's a different story.

​I am one of the most active current C128 developers, and very very knowledgeable with regards to the machine as well as the c64. The differences are much bigger than most people think, and are mostly left unexplored. A good example of one of the rare bits of software making good use of the extras the 128 has is the C128 version of Petscii robots. And I'm sorry to say, but the numbers simply show you wrong. The C128 and C128D sold close to 5 million, which is approx the same as all Amiga models together, and over twice as many as all Atari ST models together. The Amiga 1000 followed about half a year after the C128, and was in a completely different price bracket, and it would take until the A500 in 1987 for the Amiga to make that platform accessible to a much wider public. Even the ST was in an entirely different price bracket initially. Bottomline is the C128 was close to the end of the 8 bit era, but having done a lot better than most people think, and being a bigger improvement over the C64 than most people realize until they spent some serious time looking into the details.

No doubt, but C128 should've been released along with C64, as a professional computer with built-in 3'5 single sided floppy drive boundled with office suite on a cartridge. 80 Columns Mode was perfect for text processors and spreadsheets. The problem was that C= sucked at advertising their computers at business/professional market which resulted with it's bancruptcy.

The Commodore 128 is certainly an amazing computer. I call it "the fixed an upgraded Commodore 64". I think that the reason it wasn't more successful was because it cost more than the C64 and the C64 wasn't discontinued, leaving the C128 in its place. I'm planning to make a reproduction C128D(CR) using a USB keyboard, an emulator, and a Raspberry Pi computer hidden in a box designed to look like a C128D(CR) casing. I'm not sure how to make the box, though. As for if there were any 8 bit computers that are more amazing than the Commodore 128, I think there may have been, but they weren't sold in the USA. These are the MSX2, MSX2+, and MSX Turbo-R range of computers. They were all based around the Z80 CPU, although the Turbo-R also had the R800 CPU. I think the graphics on these computers were somewhere between the Atari ST and the Amiga. Another amazing computer was the Enterprise, available in 64K and 128K versions. This was based around the Z80, but with its own custom graphics and sound chips. Once more, the graphics were better than all other 8 bit computers except MSX2, MSX2+, and the later MSX Turbo-R. You can read more about MSX2 in my blog post commodore64crap.wordpress.com/2014/10/27/msx2-the-c64-killer-computer-banned-from-the-english-speaking-world-part-1/ My blog is mainly explaining what was wrong with the Commodore 64, with some posts about other computers and why they were better.

The 80-columns mode really bring a nice touch for his look and color for text mode. What kind of software I wrote in that early day? Drawing graphics (with interlaced 1 black line out of 2), phonebook, a super mario bros animation, designing space ship in the sprite editor and make them move with a space background, petscii game prototype, disk drive sector reader & trying out a custom disk format in basic where the file catalog is located on the first track/sector), trying to create some AI Chat-GPT stuff... I spend hours on the CP/M just playing in it... This is also where I first discover hexadecimal base... by doing: graphic 2,1:monitor:f 2100 2100 XX and trying a hypothesis I was having that perhaps values from 0 to F represents an arrangement of 4 pixels... and that together it control up to 8 pixels... so I try: 01 and plot on a piece of papere where the pixel lite up.. then 02, 04, 08, 10, 20, 40 and 80...

It was the shame since there was a substantial user base of C64 and C128 in former Yugoslavia. Software was not so difficult to get , but it was 99% pirate.

(Along with a commodore printer 803.) Wanted GEOS128, but by then I needed to move on to a PC clone for work. Gave the 128 away along with a couple of hundred games and programs.

Great video! And just subscribed. 👍 And I agree, it was the best 8-bit machine ever. As another poster and you mentioned, the Basic 7.0 was really good. Also, I liked how you could boot from disk. I was able to combine these features with the C64 mode to create a program that booted from disk, loaded a menu where I could select and run my favorite C64 games in 80-column C128 mode, and then switch to C64 mode and launch the game automatically. The key was a program I typed in from a magazine that showed how to load code into the C64’s cartridge memory in C128 mode. As to why it wasn’t more successful, my gut feeling was that CBM should have spent its resources it used on the C16 and Plus/4 on the C128 instead. They probably could have brought it to market earlier. And the other thing I thought they should have done is marketed it to the educators. It had more bang for buck than anything back then. And as someone who has worked in Edu Tech schools I can tell you that schools really love that.

Glad you enjoyed it :) Sounds like you had quite a nice setup! GEOS really does benefit from a few strategic upgrades. I'd love to see how it performs running on a SuperCPU and RamLink, but they're basically unobtanium now.

@@retrobitstv I haven't seen SuperCPU, or RamLink in ages. Used to see it advertised back in the day on RUN magazine (for c 64 and 128). The computer still works, but both drives need an alignment. Awesome review!! I hope that you'll do more in the future with programming and game reviews!!!!

I get a C128 from my uncle. What I like with this kind of machine, it's the ability to go to a monitor easily and try to understand what's going on.

I remember saving up my lawn mowing money to buy a 128 and the 1571. $600 IIRC in the summer of 1985. It was going to be amazing! 128K of RAM! Double the processing speed! CP/M, whatever the hell that was! A few months later my Dad bought an Amiga 1000 for Christmas. The 128 was never touched again, it felt like a dinosaur from another era compared to the Amiga.

@@retrobitstvouch Apple II’s we’re crap compared to the C64 never mind the Amiga! man the poor kid that had an Apple IIe in our neighbourhood was always over the kids houses that owned Amiga’s😂

Minor correction, the amiga never booted workbench from chips. Much of the functionality was in rom, but the programs tying everything together as a UI loaded from floppy or possible hard disk. Only in the modern retro era when you might have an emulated disk in flash would it load from chips.

Kickstart ROM, which contained low level system routines, was in ROM chips and the machine used that on power-on to display the famous “hand holding a floppy disk” welcome screen. You would then insert your Workbench floppy disk to load and boot the graphical user environment. This was slower, but a more flexible approach since updating ROM chips is costly and difficult, whereas it’s easy to release updates to the GUI environment on floppy.

Just found you (and will be subscribing), but I feel like you're a lost brother. We had EXTREMELY similar experiences with the C128, right down to DesTerm (and why!), though to be fair 3.0 was a bit towards the end of its run. I saw what you did with the REU demo there. LOL Fantastic (second? Really? VERY well produced!) review/video - thank you!

Thanks! Glad you enjoyed it and welcome :) I am pretty sure I used DesTerm v2 back in the day, as I had already moved on to a PC by '92 or '93. Still was great though!

We had a couple TRS-80s (Model I and Model 16) but *my* first machine was a Commodore 128 with a 1571 disk drive and a copy of Gyruss.

I still have my orginal flat 128 with matching serial number on the box, a 128 dcr, 128cr, and daily use 128. Thats just my 128s lol

I received my C128 in 1987 as a gift. Had no idea what it was because I wasn't so into computers before. Can recall SPRDEF, the sprite editor and Go64 (where I thought something went wrong since SPRDEF wasn't working anymore) It came with German instructions and back then I knew only croation language). Can't remember where my C128 ended up, but I got myself 2 another few years ago. Unfortunately, never used, still in the box...

Thanks for the feedback! I was using a split y/c cable with the 1084S monitor in the video when I was running Geos 64. I thought perhaps it was just an artifact of the camera so I tested it again today and that pattern is still present. Not sure what's going on there.

The 128 definitely doesn't get enough love. We had a 128 paired with a 1084 and the only minus with that machine was that it only had a 1541-II (which I still love dearly) and not a 1571 or 1581 disk drive. But I think that retro enthusiasts are beginning to see the potential. While it'll probably always be all but an afterthought because the 64 versions will come first, games that do take advantage of the expanded features really benefit from this. A title from back then would have been Ultima V but a modern title with both 64 and 128 versions is Attack of the PETSCII Robots, its 128 version even uses both monitors at the same time. So maybe there's hope in the future. Also, I noticed you only mentioned the 1571 and 1581 disk drives as having burst mode, well there was also the short lived 1570 disk drive which like the 1571 has burst mode but is single sided like the 1541. It's a rare beast but I was lucky enough to score one for not that much money recently. Great video.

I have the C=128. This is the only computer that correctly implements the concept of "emulation". The C=128 has the C=64 inside and if you are in C=64 mode there is no way to realize if your hardware is a C=64 or a C=128.

I always wanted a C128 since I owned a C64 but we had moved on to PC compatibles by then. Loved GEOS

I still have my commodore C64c and the Atari 800Xl as souvenirs from that 8-bit era, ahh also use the GEOS system for homework, Greetings.

The C128 was my first computer as a kid. I loved it but always wanted an Amiga.

I loved and miss my C-128. I sooooo badly wanted a C-128D. I also used Epyx Fast Load instead of JiffyDOS.

My family was pretty poor when I was growing up and as a result we didn't get our first computer until I was 10 years old in 1993, which was a used Commodore 64. We did wind up getting a generic PC a few years later, but unlike the C64 my siblings weren't allowed to touch it. As a family we used the PC to visit the Star Trek BBC, but my dad was the one using the keyboard and was the extent of our interaction with it. I never even knew that the 128 existed until I was an adult.

I learned PolyPascal (Anders Hejlsberg also DK) on my C128D running CP/M. After learning BASIC and ASM on the VIC-20.

C128 is still one of my favorite computers. I spent a lot of time on that thing! Sadly, I never tried GEOS 128. I wish I had now.

Watching Episode 2 in 2023! Have you seen the new C-128 core for the MiSTer? I managed to play with it a little and pretty impressed thus far, I'm shocked no one on KZread has done a comprehensive on it.

On the 128DCR (metal case), it'll be located closer to the front of the machine on the left hand side. It should be accessible even with the power supply in place. You can download and burn the ROM yourself, or purchase them on eBay. I'm not aware of anyone currently holding the license for the software so they are all bootleg copies if you will.

Late 8-bit era Color Computer 3 also had backward compatibility, new productivity "DeskMate" software, 80-column mode, twice as fast cpu, and ram expansion to 512k. I would not say it is better, except compared to earlier coco. The Apple IIC plus at a 4mhz 8-bit machine, with standard 80-column, 128k standard, expandable to over 1 mb of ram. 3.5" floppy internal. The C128 didn't have a compelling price to me. I had jumped into the computer scene, with a 1979 era Atari 400. By the late 80's I wanted another machine. The C128 was considered,.... It may have been $300 in the base unit, but by that time I realized I needed to add a floppy and a monitor to get what I wanted out of a computer. When adding up all the components, the C128 was as expensive as an Atari ST, but the Atari was true 16-bit, and software was being written for it. Anyway, as an Atari 400 user, going to the ST wasn't psychologically a big leap, even if it was entirely a different computer, with no relation to the 400.

Other than C64 game compatibility... was there any advantage to having this over the Amiga which was released at the same time?

@retrobitstv

Great question! Of course the Amiga was a superior machine in every regard, but I would hazard that the 128's selling points were that it cost 1/4 of what a new Amiga 1000 would have in 1985, was compatible with one's existing VIC-20 and 64 peripherals, and, as you mentioned, had access to a massive library of existing software.

I love the C128. But I admit I cringed when I saw that Commodore commercial drill into the side of that IIc.

Looks impressive. A comparison with Amstrad's CPC 6128 would be interesting, they seem similiar.

I owned a C64 and a few of my friends got the C128. Absolutely every one of them booted it in C64 mode to play games and used NONE of thee stuff mentioned in this video. I wasn't aware of ANY of it either! :)
