The Motivation I won't lie, I didn't have a 386 build in mind until I found a cool video card for cheap, followed by a mobo. It took on its own momentum from there. And the more I thought about it, the funner it sounded. I have a low end 486 (Presario 425 running an SX/25 CPU), and that can be upgraded, but not much. On the other hand, a proper desktop build gives me a lot more room for activities and experimentation. Exploring the limits of a high end 386 system should be fun. It's also my first time working with a full ISA mobo. The Bits: Micronica baby AT desktop case A very happy newish old stock find, which came in its original box and styrofoam. She's a tank. Asus ISA-386C The first mass production motherboard from Asus. Untested. It came loaded with a 386DX/40 CPU, and an unknown quantity of RAM. I've also picked up an i387DX/16-33 coprocessor. My reading tells me that the clock difference will not present an issue. (Will I even be running software that utilises it? Hush now.) Goldstar Prime E852 combo controller (IDE, FDD, COM, LPT etc) Untested. Handily this has jumper assignments screenprinted on the reverse side, and I believe I have also located a matching data sheet. For sound, my heart says that my SB16 will ultimately end up in this machine. But before that, I have two problem children to sort out: Addonics A151-830 (Yamaha YMF701-S OPL3) sound card I've had this running elsewhere, but it's had a bit of an on-off relationship with Yamaha's setup software. For this install I'll be testing the new utility Unisound. Unknown ESS ES688F sound card I've had this working fine as a basic Soundblaster clone, but have never found driver software that will talk to it (and have never got the MPU working). I have no manual and no idea what the jumpers are. I think this card just needs a solid afternoon of trial and error - an undertaking that was not tolerable in my Presario's all-in-one case. I will be driving external MIDI devices too - but we'll cross that bridge when we come to it. And here's the little rascal that set the wheels in motion: Ipex Tseng ET4000AX video card Untested. So it'll be particularly funny if this one's a DOA. Other assorted necessities pictured below. Neither the CD drive or 5.25 drive are confirmed to be working. Again this build will be a good test bed to determine their status. A parallel port CF card reader will be attached too, to make my life a little easier. If/when all this comes together, I have further plans to push the envelope with this build. But again - when we come to that bridge!
