Keeping in mind this is a pure dos/3x PC this is one pimped computer!
Your very well covered on the pre GM games with BOTH the MT32 and CM32
Even have AWE covered.
GM is bit lacking without the Roland counterpart though.

but this is me looking very hard for faults, All my retro PC's put together still don't cover as wide midi range as your 1 PC does.

It was a untouched Pentium 75MHz Socket 5 ESCOM Tower. I picked it up near from me, i dont want risk shipping damage.. Never seen such condition for sale in years.

This was really a lucky catch! Its a complete like new Escom Pentium Tower. It comes without a single scratch, no yellowing, even the Backplate was include first hand!
So i swapped my boards and drives into this new case.
The board was switched to the FIC PT-2007 with intel 430TX chipset and 64MB SD-Ram cl2 10ns
I switched the cpu to the 233MHz MMX. Also another HDD converter was added to the sytem for Win95. Now i can switch on the bios between the two master drives for booting Dos 6.22 / win 3.11 and the other HDD Win95.

A new graphic setup is also installed, Matrox Mystique 220 with Rainbow Runner addon and a Diamond Monster 3d voodoo1 board. The two 3dfx chips got passive cooler stones.

The cooling did a noiseblocker PL2 120 on the front, the cpu got a noctua fan. I checked the temperatures with active cooling on load (playing cybermage ^^), anything is around 37-42C° .
With the ATX PSU the system is really silent.

I swapped the drives for this setup:

- silent 1,44MB Floppy
- Gotek USB Floppy
- Quad Speed CD-ROM for CD Games
- 16x Slot in Pioneer for install and copy

I used a Roland SC-88Pro for GM before but the Yamaha addon on the MPU did a really good job, love the GM output.
The solution from Roland to output midi signal and the wavetable board audio same time is really cool and make it easy to use with a mixer.

Here another shot from the finished back, the ATX PSU fits perfect (i just flipped it). Also added USB connectors
