Ok a mistake was made. The Commodore 64's CPU runs on 1MHz. The chip itself is capable of 3MHz but the computer around it is not. I just assumed that with some tinkering it would be possible to get it up to 3MHz. (which I still think it is)

you can not simply overclock the c64 as the cpu's clock is tied to the video chip as one clock tick the cpu reads the ram, next clock tick the video chip reads the ram and so on, and if you increase the clock speed the video output will be no more pal/ntsc compatible. there are solutions but it always boils down the faster cpu having own ram and some mechanism to mirror this faster ram back to the machine, which is tied to 1mhz.

Then also, the execution was based on a 2 phased clock (so less instructions than expected). Many instructions ran several clock cycles. Thus very slow. To use the C64 properly you needed to understand all the hardware accelerator chips. For graphics it was important to understand the video raster interrupt. E.g. you could draw the 8x hardware sprites at the top the screen and then do another 8x at the bottom. Digital sample sound was generated using the volume control. Poke 54296. 4 bits. Levels 0 to 15. A change caused a DC shift and doing that at "fast speed" resulted in a crude DAC effect. I wanted to build myself a Midi interface and hacked in an Intel UART to do the 31250bits per second. Never got that to work properly on the C64 but I did eventually on a 4.77MHz XT PC clone. The funny thing was that Elon Musk lived about 30km from me and used the same C64 model. Apparently he has a bit more money than me.

No mods or emulators, all original and in their original boxes, and everything works 100%. Can still load up and play The Bard's Tale from floppies!

Actually, you don't have to use assembly language on the C-64 except for time critical stuff. BASIC is just fine for most things. Even most of the games published on the Commodore label were just BASIC programs with the occasional machine code subroutine (and not just the ones on floppies or tapes, but also the ones on cartridges, which suprised me a lot, when I was looking at some games on the C-64 and VIC-20 back in my teens, back in the day). Although there are lots of C-64 IDEs nowadays that run on modern systems, nothing can beat the authentic experience of coding everything on the machine itself. 😁

I wrote thousand of lines in 6502's assembler, and was a very instructive way to understand the architecture. One of my best memorie of my childhood.

In between interpreted BASIC and pure machine language, there were MANY programming language packages developed for the C64 with their own compilers, as well as several standalone BASIC compilers that would speed up your BASIC V2 programs immensely. Over here in North America, the RF shields are metal, and double as heat-sinks for the chips. For longevity, I would highly recommend putting a heatsink on the SID; you might also want to do the CPU and PLA. -- JC

It's a more thermally-efficient chip that is backwards compatible with the 6510, but still ran at 1 Mhz, because it was still a C64. As you rightly point out, the speed of the DRAMs was one of the limitations. The main memory in a C64 is effectively being accessed at 2 Mhz, since the CPU and VIC-II are constantly jumping on and off the bus to alternately access the RAM. -- JC

You don't know anything about Computing History. John Kemeny was a professor at Dartmouth College when he was 27 years old. Tom Kurtz also had a PhD and joined the College where he met Kemeny. FORTRAN came out for their IBM 704 computer in 1956 and inspired them to work on a similar language with IF, PRINT and GO TO statements in it. A new machine arrived at the college in 1959 with 15 Kilobytes of RAM organised into 4K of 30 bit words. Kemeny and Kurtz designed a language that could be used by a complete beginner, and worked via dumb terminals, rather than a system where cards had holes punched in them and were sent away to be processed in batches with the result of the computation coming back the following week. The very first BASIC was a compiler, but it was fast, so it supported interactive exploratory programming suitable for beginners. It had line numbers as labels for the GO TO statement to refer to. Bill Gates had no involvement in the design and development of BASIC whatsoever. Bill Gates collaborated with Paul Allen to make an interpreter inspired by Kemeny and Kurtz's Dartmouth BASIC to run on the MIT Altair 8800 home computer in 1975, which was popular in the Homebrew computer club that Steve Wozniak attended. Wozniak made the first PC when he made the Apple-I in 1976, with 4Kb of RAM, cassette based BASIC programming language also written by Steve Wozniak - before he built the computer: "I had no assembler, that was another thing. To use an assembler, they figured that somebody was going to buy this processor to use for a company, and their company can pay a few thousand dollars in time-sharing charges to use an assembler that was available in time-share. I didn’t have any money like that, so a friend taught me that you just sort of look at each instruction, you write your instructions on the right side of the page, you write the addresses over on the left side, and you then look up the hex data for each instruction-you could assemble it yourself. So I would just sit there and assemble it myself. The BASIC, which we shipped with the first Apple II’s, was never assembled - ever. There was one handwritten copy, all handwritten, all hand-assembled. So we were in an era that we could not afford tools." - Steve Wozniak Apple Computers was founded by Steve Jobs (employee #1) and Steve Wozniak (employee #2) with the money from the sale of Jobs' VW Camper van, which he had paid for by mowing people's lawns. There is no connection between Jobs and the 1992 film _The Lawnmower Man_ or between that film and the 1975 short story of the same title by Stephen King, who sued the film makers because they were going to call their film _Stephen King's The Lawnmower Man_ and it bore no relation to his story, which wasn't about computers or VR or Steve Jobs. Apple were behind the microcomputer revolution from its inception. Bill Gates snuck in because IBM realised they had mainframes and mini computers but no microcomputers, so they made one out of off the shelf parts, and went to Gary Kildall of Digital Research to see if he would license his Control Program/Monitor operating system (CP/M) for use on their IBM PC and he was out of the house flying his plane, and his plane crashed, and he died. They called Gates, who didn't have an OS and Gates made out he did, and then bought the rights to 86-DOS from Seattle Computer Products for $75,000. Ultimately this led to Microsoft being sued for $60,000,000 and Microsoft eventually settled for $925,000. 86-DOS from which DOS was based, was originally called QDOS (for Quick and Dirty Operating System), and was completed in 1980 by Seattle Computer Product's employee Tim Paterson, who doesn't appear to have financially benefitted in proportion to his contribution to Microsoft's DOS, without which there would have been no relationship with IBM (or subsequent IBM compatibles), for there to be Windows. Apple didn't steal the idea of the GUI from Xerox PARC making it "a moot point whether Microsoft Windows ripped off the Macintosh Finder", as Apple gave Xerox stock in Apple in order to see what was happening at the Palo Alto Research Center. Steve Jobs was ousted from his own company, and went off to make the NeXT Cube computer for the University market, based on the UNIX operating system, but with an OOPS-lite GUI based on Objective-C a bit more similar to the full-OOPS of Smalltalk-80 on the Xerox Star mini computer which allowed every part of its OS to have its code modified at runtime by the end user. NeXT only let you use Interface Builder to make new Applications that worked within the existing UNIX OS. Bill Gates took this opportunity of Jobs' absence to pressure Apple CEO John Sculley to license Apple's software to all PC manufacturers, so it would become the _de facto_ standard. This way Microsoft would get the Mac without having to make their own Windows from scratch. This was rejected by Jean-Louis Gassee (who later made the BeOS based computers). There was more money to be made for Gates out of selling Word and Multiplan than DOS anyway, hence the push to have the Macintosh UI on all PCs. Bill Gates revealed Windows in 1985 at the COMDEX trade show and people were not at all impressed, as Digital Research's GEM was far better. Windows could not overlap each other, they could only tile. John Sculley saw it as a rip off of Apple's Macintosh Finder and threatened a lawsuit, but it transpired that Microsoft had ALSO licensed GUI elements from Xerox and begun work on Windows before they had first seen the Mac, so an agreement was made to permit Windows 1.x but nothing thereafter, tolerating Microsoft's coincidental design based off the same source influence in exchange for 2 year exclusivity of Excel on Mac. Windows 2.0 was seen by Sculley as a breach of contract, as was HP's NewWave, and the Apple v. Microsoft GUI court case ran from 1988-1993 and was decided in Microsoft's favor. Sculley had given Microsoft permission to use substantial elements of its GUI in 1985 in exchange for Word and Excel. Had Sculley pushed development of Pages and Numbers (or their equivalents) much earlier then its possible Microsoft would not be legally permitted to have such a similar UI to the Macintosh. Bill Gates is not the "richest guy". Elon Musk is. He has $254,000,000,000+ Most versions of BASIC vary quite a bit from Dartmouth BASIC. Bill Gates and Paul Allen's BASIC was nothing significant. They didn't write their own DOS for IBM PCs. They got it off someone else too sappy to realise they could sell it direct to IBM themselves. Gates has done nothing of any worth in Computing.

@@____uncompetative Bill Gates didn't invent BASIC, but he and Paul Allen did write the C64 BASIC interpreter. @Keyboard G is absolutely right about that. I can't say how significant Microsoft's BASIC was in terms of technology, but it was significant enough to be included in one of the most if not the most sold home computer in the world. And it was significant enough for Steve Wozniak to replace his own Integer BASIC for Microsoft's BASIC on the Apple 2 because of its floating point capabilities. So I guess it was pretty swell. Your summary of the history of Microsoft is interesting, but not really related to what @Keyboard G said nor to the Commodore 64. You mentioned Digital Research. There's a very interesting KZread video out there about how Digital Research didn't license or sell CP/M to IBM. The computing world would have been very different if Gary Kildall hadn't been so stupid. And that Gates did nothing of any worth in computing is obviously completely wrong.

@@florisvandenberg7424 - While yes, Microsoft made the first 6502 port of BASIC Interpreter. So, yes, Commodore BASIC is based on Microsoft BASIC that was used in CP/M and later MS-DOS. However, Commodore bought the proprietary rights to 6502 BASIC which was a tad costly to Microsoft because royalties from those variations on the 6502 cpu like found in Apple and Atari 8 bits had to be paid to Commodore instead of Microsoft. Microsoft had to do this MS-DOS deal or they would be out of business. Lets remember that Microsoft was a software company and they made software for the various computer platforms including applications, games, etc. into the 1980s. This was before MS-DOS became as dominant which occured in the second half of the 1980s and then Windows around mid-1990s. This is before Microsoft became the supergiant they are.

You'll want to get a newly made power supply for that C64, the original PSUs have a bad habit of wearing out and causing board-killing voltage spikes.

LOL. When you opened that breadbox I got a phantom, nostalgic, tingling in my fingertips when I saw that glass fuse on the board. Y'see, I was using this as a kid and I didn't own an Action Replay cartridge which can "freeze" game states to allow code, or pokes, to modify the game to cheat and such. So, some smart chap found out that if you hit 2 pins at the same time on the cartridge slot with a paper clip, that was how the Action Replay activated its own. Problem was, get it wrong and you're gonna get zapped. Nothing too painful, the fuse on the inside blew before you got anywhere near a lethal shock. I went through a few fuses before I got a cart.

Despite of some mistakes (CPU speed, etc) and judgements (“Horrible” blue screen), I admire the efforts you put into this video even though this computer is much older than You. For me, it was my first computer, and back then it was state of art, top of the line, best in class, absolutely amazing graphics / music. The sample music you played is from 1983 which is super early in the platform, try Last Ninja 2 (1988). I still use sid chips and an 1982 SX64 during live music performances in 2022.

I like the Saab poster.

6502/6510 is fun. Complex and fun.

Now you need the Mapping the Commodore 64, which is available in PDF. Also C64 Programmers Reference Guide, and a Machine Language Monitor cartridge. 6502 is my second favorite language.

It boots up quickly in part because it doesn’t have to load megabytes of data from a disk drive. Technically, a PC boots quickly, the raw PC board that is, via its BIOS, that’s stored on ROM. What happens after that is the bit that takes the time.

let's go my inspiration

I’m still a begginer programmer, as I started studies in computer engineering. Studying the 6502 have helped me understand more CPU architecture and how it works. I’m just learning how it works because I want to make a NES Emulator ☺️☺️☺️

In that case watch my assembly course that I started as of last week. And the C64 had 1MHz.

Awesome! Good job. I was hoping for more playstation stuff though. The PSP is dev friendly fro example.

I actually have an interest for old computers like the Commodore 64. I sometimes code a bunch of little programs for these old computers. (Not exactly games, since I'm bad at making games in Unity, let alone 6502 or Z80 assembly) Also, it's because I have a mini-nostalgia for these computers (Back in 1990s Poland, the best computer you could buy at the time was a Commodore Amiga, and it was very expensive, hence the Commodore 64 and many other older computers became popular there due to its cheap price, as well as its availability)

haha, your "horrible blue screen" was the warm welcome screen to gaming in my childhood, anyways, nice to see young lads taking a look at old tech :)

I found a C64 in a thrift show in box with a 150$ sticker on it, the lady goes, "oh you're buying a keyboard 2$" haha this was in 2005 or sometime.

2:00 INC isn't a supported 6502/6510 instruction. That would come later with the 65C02.

Just wait until you get to scrolling a screen in assembly. Then you experience full body pain, including a head case, lol. Miss this ole machine and all it's bits and bytes. Have your friend to try use a timer as a delay since it can sync with the machine better also. I didn't see the full code, but caught the brief glimpse of a nested loop.

Get a new power supply or some overvoltage protection for it. BTW I love what you got out of this great computer. The Commodore 64C was my first computer. I got it in '88 at age 11 😎

Next up, SEGA! Good job Filip, have some white tea

I think at this point in time it makes more sense to code in C (CC65) and inline ASM where needed. I last coded on a C64 around 2015 using ASM and found it far more frustrating than my current coding experience using CC65 and NESLib for an NES game.

Assembly was for those who could afford £50 for an assembler. My first computer, when I was about 8, was an Amstrad CPC with a Z80 chip. There were these mysterious 'pokes': cheats for games that involved using the POKE basic command to write bytes into memory. I never understood then, but wish I had, how they programmers were writing assembler with pen and paper, and hand assembling them to make the machine code numbers to be POKEd into memory and CALLd. I think the modern world has lost too much of the 'do a lot with very little' ethos of computers back in those days.

Nice haircut! Fits you more!

The CPU runs machine language - not assembly. Assembly is already an abstraction of machine language and needs to be assembled into machine code instructions: Let's take LDA (load accumulator) for example. It translates into 8 different opcodes, depending on how the accumulater is loaded (immediate, absolute, indirect, etc.). Assembly usually also does provide macros (for labels, data types, etc.). Without labels for example you would need to know every single address for loading, storing, branching, jumping at coding time.

If you think the Commodore 64's bootscreen is horrible, then you aren't worthy of touching any computer.

I’d gotten my C64 in grade 9. The school had a computer course with VIC20s at the time. I’d also taken a typing course with electric typewriters not because of girls but wanted to type faster. Cool to see another generation get into this!
