Busy, busy day. First time to myself for a few weeks, determined to use it to the full and did so.
First up finishing a few builds:
1) the weird one - Alaris Leopard with IBM 486SLC2/66 - a stupidly fast 386SX with VLB slots
Here I needed to decide what to put in it, and get it all running. Unfortunately found my 'good' CL GD-5428 was only good for the first 256kB and artifacts like hell in SVGA. So that leaves us with:
- Diamond Speedstar 24X (WDC 90C31) 1MB ISA VGA
- UMC-based VLB I/O
- 3C509TP NIC
- Mediavision ProAudio Studio 16
- Aztech Waverider 32+ (AZT2316+ICS wavetable, hardware SBPro2 and WSS compatible
- 16MB RAM
- the one really cool case I have
- runs DOS 6.22 like a dream, even went on internet with it - because I could 😀
2) my UMC build. Was having a lot of I/O problems with it, couldn't get the (UMC) NIC to work and worse, didn't have a clear purpose what to do with it once it was ready. Then I realized that an U5S-33 is pretty close to ideal for an Ultima 7 build, so merged that idea with this one.
- TK 8498F So3 VLB motherboard
- U5S-SUPER33 CPU
- 16MB RAM (to be upgraded to 32MB or better 40MB once I find enough FP so I can run U7 from RAMdrive)
- TK 85C418F VLB VGA+multi-I/O card. Very touchy about which slot it sits in and needs TLC and squeezing at times to make the FDC work - but very UMC in everything.
- UM9008F-based NE2000-compatible NIC
- ESS688-based sound card - with UMC chip for CD-ROM (unused...). Managed to find the mythical ENMPU.EXE MPU401 enabler "TSR" for ESS688. It runs, it claims to have MPU on the right port and IRQ (then disappears from memory, so not very TSR). And it utterly fails to output anything over the MIDI/joystick port :'( - so...
- MusicQuest MIDI card. No UMC, bit of a combo-breaker. But at least no-worries MIDI.
Took a bit of messing around to get turbo and LEDs to work correctly, but running now. Only issue is that de-turbo-ing doesn't slow this system down that much, only about 66% reduction, which might not make it suitable for really old stuff.
3) decided that my stupid 5-sound card attempt was pointless, so started to re-distribute the prize specimens over other systems. Then realized that having a P200MMX for myself for retro gaming and a K6-2 350 for my son, both running native DOS, didn't add much either, particularly as there isn't enough room to play on two separate systems at the same time anyway. So now starting to merge my game system with his and adding the GUS classic and AWE64 Gold to the mix. Hope to get that all running later this evening.
