Is there any reason to choose one of these over a DB50XG other than its smaller?

I'm waiting for my LT to arrive. I'm planning to run it alongside a Roland SCC-1, using dual coax to mini to pipe its sound into the Orpheus II. Also have a DB50XG board to use with it at the same time. Do you think I will run into any compatibility problems? I havent seen any mention of running the …

Your welcome! Glad I could help. I replaced the simm sockets in my board with the nice metal clip new ones. Still no luck getting it to boot off my Adaptec AHA-1542CF card, it has the boot bios and should work. Running it just off floppies, its working great. I hooked up a Gotek floppy emulator unit …

Wanted to update. I was able to find some working Timekeeper modules on ebay, so that problem is fixed. Got some intel branded 1mb parity simms, and they work properly. The old simm slots are cracked and some of their plastic clips are broken, but I found new amphenol metal clip sockets to replace …

Wanted to update, of course the clock module battery is dead. I replaced it with my Glitchworks and although it did work for bios settings, it s aid the time of day clock was stopped. I'm guessing I need a different module, need to research since the one in the computer isnt a Dallas, its an ST: …

Woohoo! I scored a USIT Athena too :D This one has the hard drive carrier so you can see how its arranged. We both have the same BIOS revision. The Dallas battery is dead, but I have a new one ready from Glitchworks, just not with me at the moment. For the EMS memory, just go to the second bios …
Re: Tandon 286/n

Random info for you: The chipset on that motherboard officially supports up to 20mhz 286, but not 25's. Use the fastest ram you have hopefully 60ns or 70ns since the memory controller sets wait states automatically based on the speed of the bus vs speed of ram. 16mhz needs 100ns ram for 0 wait state …

The Dell System 210 uses this same motherboard. Dell bios of course, and they set theirs to only run at 12mhz with 6mhz bus. The white paper on this Faraday chipset says it supports up to 20mhz 286 cpu's, and runs the ram at 0.7 wait states. My Dell 210 has a dead board, but the Athena you have here …
Re: Gotek Floppy Emulator with FlashFloppy
Posted on 2021-09-22, 02:19
I recently purchased 3 of the new goteks, the ones with the larger screen, built in knob, and newer microcontroller. The ebay seller sells them flashed to FlashFloppy 3.28 in beige, yellowed, and grey. These are for use in my retro PC's. When I hooked it up and turned it on, I pressed 2 buttons …
Re: Promise SATA300 TX2 Plus versus Asus P5A On-board IDE
Posted on 2021-08-10, 05:38
I have messed around with sata cards in some of my retro builds, except that I prefer to run Windows 95c. There are no drivers that work for any Promise sata card in win95 that I could find. My work around was to use a Promise PCI IDE133 card, which does have win95 drivers, then plug in a CF adapter …

There is a DC-200 on ebay right now that seems to have the LBA chips. It has the instruction addendum for the LBA bios, and an extra set of bios chips included. Just search for Promise DC-200 (no relation to seller)

Dont forget about '99 workstations. I have an HP Kayak XU800 from 1999 with 2gig rambus(4 channel), and dual P3 733. It has AGP Pro 4x, and intel i840 chipset, top of the line for its time. Video card has been difficult, I really like the Matrox G400max, but have been testing an ATI fireGL X1 256mb …

This is gold for anybody working with a vintage XL system! Amazing that you found that softpak in the mountain of online softpaks with nameless numbers, like a needle in a haystack a kilometer high.
Re: IBM PS/2 Model 50 Hard Drive

The best solution I can think of for any 50pin scsi systems these days, is to abandon the spinning drives fully, and go with SD cards. You will need a MCA 50pin scsi card, but that will allow you to use a SCSI2SD adapter. I have a SCSI2SD v6 adapter, which is fantastic. It allows you to break up a …

This was very cool! I have been playing around with Quake1 over the last week on my Micron big tower with P2 350 and G400max. I have a P2 400 on the way for it, and your benchmarks give me something to compare to when it arrives. I also tested a fresh install of 1.08, then GLQuake, and although it …

That was great! just what I needed! I have reflashed the bios to the Micron P15 you found. The oemlogo and oeminfo both work too, I needed to fix the line numbering in the oeminfo, but everything shows up properly. With the P15 bios installed, my Promise TX2 133 card now works correctly. I have a …

I have since flashed the motherboard bios to the Intel P17, and yes, I did lose the Micron splash screen, it was replaced with an intel splash. Made me frown, but, it was worth it for the hugely improved BIOS over P02, I dont regret flashing it. After searching the old hard drive, it did not have …

The Millennia big tower arrived safely, wanted to share a few pics. The original 8.4gig IDE drive was still in it, and still loaded with software, looks like the last file access was in 2010. There is a 92mm exhaust fan near the top of the case, that I'm replacing with a fresh Noctua. The P2 350 cpu …
