The Awesome Reason Why My MS-DOS Gaming PC Needs a Pentium MMX Cpu Upgrade!

I love this MS-DOS Pentium build! It is a great MS DOS 6.2 gaming PC based on the Philscomputerlab time machine concept. But I need a better CPU with MMX Instructions. So lets benchmark and swap cpu's!

Support me by buying on Amazon!

I started an Instagram. I will upload small Unimog clips and Updates!

Big thanks to my Patreon supporters you are awesome!

The really cool feature of the MMX is that it has special methods to slow it down with SETMUL utility. That way you can run older games that otherwise would run way too fast 🙂

Pretty cool video. Trip down memory lane, a time when things were simpler, but technology advancing at blistering speeds, and life was a bit slower and relaxed. I honestly miss those times.

You can use rubber feat, piece or pieces to keep the card from sagging. I used that method for my Ultrasound max v1.

After long time games with retro hardware, i agree with 200mmx/430tx is the best combo for dos games. Its cheap, easy find, no simm72 ram shit, have fast pci and lots of ISA. Minimum soft and glitches, easy configure and you got 386 from it by cpu cache disable. I use it my permanent retro setup on everyday. I recomend add to you system Promise FastTrackTX100 or 133 adapter, to reduce CPU load with disk operation and get superb hdd speed (i dont use heretic CF shit).

Beautiful PC. You should really try the amazing 3D tech demo called Into The Shadows made by Triton in 1995. That's the most impressive 3D DOS demo I have ever seen. Too bad the game was cancelled and never made it to the stores.

Of course You need it. Between 1996-1998 there were still some games which people launched not from Windows but - for instance - DOS Navigator. Comanche 3, Armored Fist 2, Quake, PowerSlave, Advanced Tactical Fighters or Blood. These games were quite demanding and a strong CPU was necessery. And of course it was possible to play these without Windows crap😅

I think I remember that sliding door. It reminds me a bit of the Colani tower we had as our 486 DX2-66 from Highscreen. There used to be a Vobis store near the CCH in Hamburg, by the Finnlandhaus.

Ahh, Norton Commander, it was a must in the DOS days. Today I use Total Commander.

Nice computer system with a great upgrade. Keep up the good work Victor Bart. Greetings from Steven from the Netherlands

Oh-you could clean the monitor screen!

Thanks for bringing up the Heaven 7 demo... Wow, it has been over 20 years since I watched it. It is still amazing. Too bad it did not run properly.

[looks-suspicious]

Parts of the case look very yellow and could use some retrobrighting. The hardware itself is amazing though. Maybe you could swap the spinning rust for a DOM or SSD, if the noise from the HDD spindle annoys you? The extra PCI slot could fit a SATA controller (I use a Silicon Image 3114 in SATA-only mode).

I knew exactly what was coming the Second Reality started. What a dose of nostaligia.

[christiangroenheide]

Jij kon een klasgenoot van me zijn geweest. Mooie tijden man.... zo mooie herinneringen aan....

Ideeen om dit systeem aan te passen? De stof eraf halen en wat peroxide om hem splinternieuw te laten uit zien. Buiten dat... dit is plaatsverspilling... een raspberry pi 5 maakt gehakt van dit systeem. Stil, heeft hdmi poort. En kan ook andere systemen emuleren zoals Amiga.

[dabombinablemi]

Looking at the machine before you open it - you probably have the CD drive in the second slot so that you can run the zip drive off the same cable.

My Windows 95/DOS machine came with a single 128MB stick (which was dead) but I decided to go with 2x 32MB PC66 sticks that came with its replacement "PII 233", as every other functional stick I have is PC133, and also 128MB+.

I've found that a Pentium II 233 (or a 350 standing in for one) to be excellent for DOS game compatibility. The couple of speed sensitive games I have (outright refuse to run on anything faster) work well, and even Unreal and UT are playable (and enjoyable) with the Riva TNT and Voodoo2 that came with the system. Still want the OG PII in the machine though, as the case has the PII MMX sticker it came with. By coincidence it has also been my most trouble-free retro PC, beyond occasional motherboard capacitor failures (PSU is fine as it's a 145W FSP unit from a Voodoo3/PIII 650 Packard Bell).

*sigh* an MT-32... the device that keeps eluding me... great machine, Victor

I am in AWE!!! What an incredible build!

I had that same blinking monitor issue with an LCD when attached to a Diamond S3 Virge card in DOS. The monitor was a 1280x1024 TN panel and supported 60-75Hz, so the 70Hz Vsync in DOS was supported, but for some reason it didn't get along with that card. I don't remember which other video cards it did and didn't like.

It seems like an issue that can happen sometimes with video cards that predate LCD monitors. LCDs are more picky about the signal than CRTs.

Just a warning for anybody who doesn't know:
This motherboard has a jumperless setup so that was indeed a simple CPU upgrade.
But in general - most socket 7 boards need jumpers reconfigured when you do this. Classic Pentium, MMX, Cyrix, AMD chips all have different voltage requirements and draw different amounts of power from the split voltage rails - so if you don't check the manual for correct jumper settings, bad things can happen on those boards.
It was probably the confusion of this period that led to the jumperless, automatic setup that Pentium 2 natively supported.
Socket 7 CPUs don't have a signal indicating their voltage requirements, but apparently this board has some trick for figuring that out.

Nice video, , look likes your monitor is very dusty ?

I never really used Zip Disk, They were new in High School, I was poor, and so was our school (Kid Rock High Class of '01)
a few years later, 2k3+ I was still using Large Format Tape Drives for Daily & Weekly Backups
I always wanted one for my Trash picked White box when they first came out, I always wanted to attempt different OS's Booting from different Disks.
I LOVED DOORS! I had a Sweet PII Gateway Tower, that I Implanted a Duall PIII Motherboard as my Work Quake III Server for Lunch time lol
