Th99 has been well known for donkeys years. Uh19 link is in my sig. (Only motherboards at the moment) Th99 is a very good source of information, I have a local copy and an abridged copy of Microhouse Technical Library which it is derived from. I've used th99 for over 20 years. BUT there are 1000s or …

Yeah, its a unique back I/O plate. I will have to make one. As for drives I want to be with-in the time period. So NO 10k rpm or 15k rpm drives. Looks like the same as the Intel MS440GX motherboard* with the Parallel/serial and USB bunched up closer to the Keyboard port. Also the odd Sound output. …

Looks like a cool system. Have you got a backplate for the I/O ports? What HDDs are you going to run? 10K screamers? were they out in '98?

Attached is the PEAK/DM bios. I may have got PEAK/386 and PEAK/DM round the wrong way. Try it and see if it works. Please let me know and I will put it on the UH19 page.

IIRC I think serial runs upto 24V anyway so shouldn't be an issue on that front. May want to check that though.

It should just work. The controller doesn't need to be jumpered to DD. It's just that the XT wont be able to use the HD data rate used by 1.44MB disks. If you read a 720KB disk on an AT, the controller is behaving as it would on an XT. All floppy controllers have no idea what you have connected to …

Be interesting to know how you get on. That IBM looks sweet. Always wondered about POS. Parents had a cafe for a while and though to using one in it, but old till met their requirement fine, so never got to play with that hardware. Still would like to play with some of this stuff but always stumped …

I've never had any compatibility problems with using 1.44MB drives in place of 720KB drives either. 5.25 drives are another kettle of fish. Here is what i would recommend to make a boot floppy. 1. Wipe a 1.44MB disk with a magnet then tape over the density hole. Or just get a 720K disk. 2. Format it …

Specifically on the form factor field. There are a lot of OEM/Prop. boards that are not yet identified as such. We went through 5000+ boards looking for errors. AT and ATX should be fairly accurate. IIRC at the time we didn't have an OEM/Prop. category. An oversight. There is also the 1000s of …

You mention you stuck an AT keyboard in it. It's an XT so needs an XT keyboard. Check if your keyboard has an XT switch on the bottom of it. You'll get nothing out of an XT with an AT keyboard. No idea what the beep codes mean, could be keyboard, could be RAM. The few DTK BIOS board I've dealt with …

FYI the netserver LM is documented here: https://www.ultimateretro.net/motherboard/show/2834. There are 2 manuals there that cover various early netservers. Buy they are very scant on info. I'm currently documenting the early netservers. Don't think i've found the LCII, got the LC3 and LC though. …

The first boards for PII were 440FX in early '97, around mid '97 (IIRC) it was the LX with the all new AGP. IF we are talking dual, then LX boards seem hard to come by in my experience. The FX boards were used in loads of mid-range servers so there are a few more kicking about. What you go for …

Iirc that interface most closely resembles st-506, so you may be able to do a hookup that way. Or just go with an addon card. SCSI is probably going to be the easiest.

I think that Compaq PSU is a similar size to IBM PSUs from that era. I have crammed the IBM EPS12V PSUs into all sorts of midi tower cases. Antec/Chieftec cases come to mind. IIRC i could get two of the screw holes to line up properly.

I'm a bit confused by this long thread. so forgive me if i have missed a few things. The target is win 98 compatibility. So we are excluding those very old cpu-timed games that only run on an XT. And we are excluding games from the XP era that don't support 98. So we are left with (broadly) 2 types …
