The ol' big squishy clicky power buttons...Something I competely forgot about my old PCs. The feeling of pushing in a long throw switch reminds me of waking up during summer breaks to play hours and hours of wolfenstein and later doom. Hearing the click followed by the 'beep' of the bios startup, then followed by the drive self checks. I can still hear all of these sounds in my head, and the smell of hot computer components/case. I imagine my nostalgia towards PC games is similar to what my grandparents had with old vaccum tube radios. People become so wrapped up in the large generational differentials that they don't realize that every generation is the same with varying experiences.

+Mirsad Redzovic Same here. And didn't get the QEMM conflicts that way, either. The trick was to go through all your TSRs and determine both startup RAM and idle RAM (from the full MEM report), and fit 'em into available spots instead of just cramming 'em in one after the next. I ran a bunch of handy TSRs on my 286 with 1MB of RAM (and some of that locked out because of a bad chip) and still had enough RAM to run everything a 286 could handle. Speaking of memory tricks, anyone else use a memory board? I have one in the 286, 2mb board, the system wouldn't see it as RAM but would as a RAMdisk, so I used it for temp space and for workspace that was much faster than writing to the HD. Its contents would survive a reboot, so data loss wasn't really a problem.

+Mirsad Redzovic That's a great idea with DOOM, I'll have to try that. Still the only game I play. Right now I run it on a P4-3GHz (some of these huge modern WADs need that much horsepower) but if it ever dies I'll have to look for another solution. I put my browser cache on a RAMdisk both for performance and because it keeps the mess off the HD -- the way the Mozilla-based browsers handle cache is stupid beyond words, and causes fragmentation like nothing else in the history of computing. I use DataRAM's freebie as it works well, doesn't eat much, and has a good "hibernation" feature.

What fun that was running QEMM to make room in the 640 K base memory. Without Quarterdeck Expanded Memory Manager, it felt damn near impossible to get some games working. It did have windows but that was Windows 3.11 and was nearly useless by comparison to todays windows versions. Many of the games for Windows 3.1 were those horrible point and click adventures.

There are new old Chinese motherboards 754 stuff onwards, but there would not be much call for pre 2000 tech. Better to look for ancient PCs at recycling centers and any companies that resell them. Check Craigslist for collectable ancient junk, people do occasionally sell them. You can also pick up $40 Atom ITX motherboards (cheap) that maybe could be throttled down (features turned off) to 486 performance.

Amazing that you can mix new and old like that. Very cool

Interesting build you did here!

9:00 I actually said out loud "yeah your video card isn't working" when I heard that POST beep. Oh, the good ole days. ;) (that beep here means the monitor isn't connected, but the card may be working fine) 13:20 - only certain USB mice (old ones, usually) have the capability to be used with a PS/2 adapter. It's completely different signalling, and the adapter is just a physical bridge, no USB/PS2 adapter logic inside. FYI. 14:00 - possible that the CF card doesn't support the detection or the I/O mode used by the 486, but the card would still otherwise work OK. Possible that the card only works with LBA (which USB adapters and all modern PCs us), and the BIOS is trying to use CHS mode. 14:05 - yes, resistors are extremely, absurdly, mind-blowingly important when working with LEDs. ;) And be sure you're using the right resistor for 5V or 12V supply, too! 14:45 - you should probably not leave all these to defaults... back then, RAM didn't have the little Flash chip on them that provides parameters. So, it's important to set EDO mode if you have it, so the chipset can make use of EDO memory's extra speed. But with 8 MB of RAM installed, I doubt it's EDO... y u no eBay some EDO stuff? :o

I can't believe you're running that DX4 without a heatsink and fan. A heatsink is required on 486 CPUs starting at 40 MHz up to 66 MHz. A fan is required on 486s 75 MHz and faster. That chip is going to suffer thermal death if you keep running it bare, which will be a big loss because Intel DX4s are both rare and expensive due to not being mass produced. AMD and Cyrix parts of similar speed are more prevalent, but less compatible with boards using Intel chipsets.

DX4 is pretty low power like the original 486DX-25 and 486DX-33. The DX4 runs at 3.3 volts, while the faster 486DX2 chips ran at 5 V. Since voltage is exponential for power consumption, a 3.3V chip can run atleast 2.3x the clock speed (3.3^3.3 vs 5^5) at the same power consumption. On top of that, the DX4 (0.6um) was built on a smaller manufacturing process than the DX2 (0.8um) and previous chips (1.0um) so they'll inherently run faster at lower power on top of that. Back in those days smaller fab size directly translated to power savings AND performance increases. That said a heatsink wouldn't hurt :).

@GGigabiteM

7 жыл бұрын

jrherita Core voltage does not directly determine the power consumption of the CPU, nor does it determine the clock ramp. Just because the CPU has a lower core voltage and a smaller lithography process, doesn't mean it will use less power. Take a look at modern CPUs, the core voltage can be 0.8-1.45V and pull 100A, or 40-150W. Despite the DX4 having a 3.3 or 3.45V core voltage, they pull the same or slightly more current than some older DX2s. AMD parts on the other hand use less power (the 133 MHz part uses ~4.5W) and still require a heatsink and fan.

@jrherita

Back in the 1990s when Dennard scaling worked, my statements were correct. Modern process nodes (since about 65nm) is where power scaling stopped essentially so to compare a 486 and a modern CPU is apples and oranges in that way. An Intel DX4 @ 75 mhz should consume less power than a DX2 @ 66 mhz. I suspect a 100 mhz DX4 will also.

Excellent work, Phil. And I am very very interested in videos like this. I started out using my first "real" computer in 1993 which was a 486SX 25MHz with 4MB RAM and a single-speed (150kb/sec) CD-ROM drive. I ran a program called Vistapro which was a fractal-based landscape rendering and animation program. Endless ours spent creating and rendering. Full detail could take hours at 800x600 resolution for 1 image. I later ran the program in a command prompt on WinXP on a AMD 3500+ with 2GB of RAM (not that it even used more than 1MB or 2MB) and the program ran so fast at full detail it was rendering in real time. I was blown away. I think companies like Microsoft, Adobe, etc. inject so much bloated code that programs run slower and slower on modern hardware. Thank you for the video.

The floppy adapters are mainly designed for stuff like CNC machines where a modern replacement that supported newer storage would be really expensive

I would say the other big negative of AT power supplies is that they do not use soft-power like ATX, you have to run the mains voltage outside the power supply to the front panel switch, I have had a mishap before where the quick connect terminal came loose from a front panel switch and shorted to the case and sparks flew and the breaker tripped.

it's probably mentioned elsewhere on here amongst the comments. the type of switch your referring to is a 'latching' switch - just incase anyones looking.

Ive forgotten most specifications for these old things. That was actually kind of exciting.

Just an FYI, if you don't want to use an ATX power supply, they still manufacture AT power supplies. You may have to do some hunting but they are still used in a lot of industrial equipment. You can get them brand new from manufacturers like Startech. You can also get XT power supplies for even older systems that are new and recently manufactured. Many arcade machines use them, so you can get them from arcade vendors a lot of the time.

Anyone know where you can still get these? Only thing I can find now is Athena Power - which doesn't inspire much confidence.

I usually take an old dvd case and use one side of it (Label Side) to cut out and make a cheap plastic IO shield.

Thank you for this video. What happens if you have a 486 that wants heads cylinders etc for the hard drive in the bios and you only have a flash card? My bios doesn't have autodetect. I have the same adapter from from startech.

Thinking of building a 486 and being able to use it in an ATX case would help! AT cases are still around but go for a fairly static £60 on eBay which adds yet another significant expense and often they're heavily yellowed, rusty, bits drilled out etc. I had no idea you could physically mount them, with the same standoffs. Plenty of options for the switch.

aw man now I miss my 486 DX2 66mhz and 8mb ram, 400mb hdd, I put a full creative kit on it, cd rom, soundblaster 16... all the good stuff :) Used to play Raptor so much :)

+PhilsComputerLab The day I bought that box to my house was the best day of my life! (at that point at least lol)

omfg HAL. I used to use that exact same benchmark to tweak PCI and CPU timings back in the day to get the highest frame rate and bus speeds! When I went from a 486 to a Pentium 90, my performance actually went DOWN because the ISA bus clock modifier was way too conservative on the new motherboard and wasn't configurable so I had to go to PCI video, then that thing FLEW like 400fps.

OMG, I remember playing that Raptor game a long azz time ago!

Hello Phil, what type of ide - CF adapter you use ? Can you post link for it ? Thx

That one is an expensive one from StarTech. Because it has a drive bay. They cost more.

That's amazing the processor runs without a heatsink and fan.

Great nostalgia build! I never owned a 486 (went from ZX-80 --> C-64 --> Amiga --> 60 KHz Pentium), so I'm surprised to see that it ran without a heatsink on the CPU.

Er, 60 MHz, not kHz. Stupid Swype!

I always did build my PC's from ATX sized items small and mid tower. But, what is the max memory and drive sizes can we now use vs the old way and video?

Electroetching would be an easy way to make a factory quality hole for the PS/2 connector on the I/O shield. Fun build btw :)

You connected the external pwr button to "Turbo" button connector - that's why it slows down when you press it! The turbo button changes the processor clock.

+Gaston Electronics Yes that what it does. On some boards you got to close the jumper for full speed, on others remove it. There is no set standard :)

DOS is the wave of the future! I miss my 320x200x256 color mode. xD
