Mini DOS Gaming PC Part 2 - CPU Upgrade + Benchmarks, Building Soundcard 

I had the joy of spending the past weekend with the SiS version eBox, having FPU and MMX, so it ran Windows 2000 like a dream - but drivers was a big problem. Only working good on XP and no sound support in DOS for the SiS 7019 AC'97....

Now design a PC104 Voodoo II board.

Nice upgrade. I'm glad there's an FPU-equipped variant, a lot of people forget that the Build engine used the FPU too. The only exception are the games running on the earlier version of the engine that didn't use slopes, like PowerSlave/Exhumed.

I remember seeing the OG VorteX86 back when it was new, and I thought how cool it would be to make a DOS gaming system from it. Glad someone finally has.

So far that is the best DOS gaming console project i ever seen.

1:35 lol Super cool follow up video!

Mate this is amazing! And thanks for the link to that PC/DOS Mini game collection. That's a fancy menu system, and I bet I've got just abot every game on that list already on GOG! Weekend project sorted!

Really awesome to see this build progress!

Well, the original Vortex86 was based on Rise cpu core and SoC architecturem licenced by SiS and DMP. Vortex86 SX is actually a different CPU created by RDC Semiconductor, hence the big difference in perf/clock

I love your turn table! :P

Great work!

I loved that you used a turntable as the, well, turn table.

Love this!

Great vids!

Nice! Mine is almost finished :)

Simply fantastic. Would love to buy one!

TROGGGGDOOOOR! :)

Amazing project, it turned out awesome. You wouldn‘t happen to sell these as kits?

So cool

This makes me pine for a handheld DOS device, instead of these emulator handhelds with aging RK processors.

"I imagine the reason for this is power consumption" Maybe part of it, but it might be bottlenecks and/or architecture differences. a cycle for a Pentium or Pentium 2 would not equal a cycle for a cycle for a 486 so if the computational efficiency per cycle is essentially double or triple then you would have 900Mhz 486 = 300 Mhz Pentium II or whatever.

Nice stuff. How much do those PC104 boards cost? The crystal chip is okay but has a somewhat inaccurate OPL3 implementation. Does the onboard video card run demos like Second Reality and Crystal Dream 2 without issues?

Was the power adapter included?I considering pulling the trigger on a couple ebay options that should have fpu.

Do you by chance still have the Gerbers for the end plates? I’d love to get some printed! Sorry if you’ve already mentioned it somewhere…

Cool, I would pay alot for this.

I didn't know about UTSource but since we talked about the ESS Solo-1 in the other comment section I looked it up. And they do have the chip there still! ES1938S . If it is compatible with these boards the same way it is with the VIA motherboards and TDMA works on them then you would get excellent sound blaster and especially adlib compatibility. It would sound very close to an OPL3 and in some games it can sound better. Might be a great fallback if you have a board that won't accept these ISA chips. If you ever make a retro PC like this for the 98 era, another good PCI one could be the YMF744B-R which also has some native DOS compatibility with a TSR (Not as good as the ESS Solo-1) but inside windows it would have fantastic wavetable midi synth with Yamaha XG support. A3D, and EAX support. And it has a native OPL3 built in.

unfortunately i cant find any PC-104 boards in Australia..... i really liked the small form factor you got ...must keep looking

Awesome work! I am also doing a PC/104 build, and i am stuck on the RJ45 breakout.. how did you wire it and figure it out on yours?

Pretty cool! Could you share the name and model of the thin client you used?

A comparison to my Cyrix MediaGXm @ 166MHz with an S3 ViRGE 325 PCI VGA card 3DBench: 102 Chris3D: 73 PC Player: 29.0 DOOM: 59.75 Quake: 20.8

6:33 At what temperature (Celsius) did you solder the surface mount components? This would help me in the future when I try to solder the sound chip for the WeeCee PC.

what sound card off ebay did you buy? I want to get one for my dos pc

Amazing job! I'm working on similar project but my goal is run Windows 95/98

Hmm, what are those thin clients? Eeebox is an Asus Atom based thingy, seemingly. EeePC derivate. Happened upon these types of CPU's recently on This Does Not Compute's video about fastfood ordering system. Still works, I guess. :)

1:35 The fok-drop

How does this company have x86 licenses? I thought only Intel/AMD/VIA (now Zhaoxin) have active licenses, yet DM&P somehow still produces these.

Ya but can it play crysis! :) Awesome follow up, found your channel on the first Wee86 video. Always refreshing to see other creators ideas and how they accomplish them. Looking forward to your other projects.

You said there'd be networking

Hey, were you ever able to find the value of that ferrite bead you used? The parts list you linked to just says you didn't know the value.

I might build one myself to be honest

All you need now is a proper crt monitor.

You can probably sell thousands of these.
