Digging up old thread at tail end on 2022 to share my experience. I could not source earlier this year in EU angeled twin SIMM replacement sockets with metal tabs. So I opted for 2 separate vertical ones. Even that ended up costing way more than I'm fully happy with with shipping from US + taxes …

Did you ever get this to work? I have this same video card in a Portable PC III with the exact same symptoms. Trying out the drivers you noted, using a combination of switch and eagle, I found that if I turned off extend mode, it changed the line above it from NTSC to CRT, and then video was fine on …

I did another check and realized 4+6 are tied together on the DB9 and 5+1 on the PS/2 as well: PS/2 : DB9 1 not connected to DB9 2 > 2 3 > 5 4 > 7 5 not connected to DB9 6 > 3 these are connected together on same end: DB9 4 + 6 PS/2 5 + 1 PS/2: pin 1 lower right looking into female connector DB9: …

Yes, in the end I got a working adapter for it. I bought another mouse that claimed to be NOS, however when I got it it was dirty and I don't even believe even serial compatible. However, it did come with a sealed I assume generic adapter, I'll include a pic anyway, which did work on my original MS …

Thanks, I'll clean it up and replace just the 2.4v cmos battery. Luckily doesn't seem like really spread beyond the connector. It's interesting to see it actually followed the wires down into the board. I'll just leave the 7.2v battery off

I'm replacing the CMOS battery on a newly acquired Toshiba Tecra 550CDT. I see it has two batteries on the motherboard, a 2.4v 30mhah battery I think is the CMOS battery and seems readily available on eBay, the second is a 7.2v 30mah battery I'm not sure what it does? It seems I saw something …

To follow-up, got my 68666 adapter and it didn't work, it does look like they were made for each other , same color, line and dot design Here is the pinout I was able to come up with, it doesn't quite seem to match the ones from Snufkin PS/2 Serial 6 NC --> 3 RXD 4 +5V --> 7 CTS 2 NC --> 2 TXD 1 …

Thanks all - I'd assumed it was a standard, makes sense it's more a workaround at the manufacturer level. I thought it was a little weird they gave the pinout for the adapter on the item listing, but now I'm seeing at least a few other pinouts The 68666 adapter does seem like it maybe it, I see one …

I know not all PS/2 mice work in serial mode, but this mouse specially says "Serial-Mouse Port Compatible" and also lists 12v power usage (and 5v) which I believe is serial-only. v2.0 Part No 58264 I'd tried using a PS/2 to serial adapter I found in a drawer and it didn't work, so I bought a new one …

Awesome, thanks much again. There was a few things I was curious about but didn't wanna twist your arm. If you find any other old media, things I think people would appreciate are ASPI drivers, there's a number of interfaces and drives that aren't supported well by drivers that "survived" onto …

Here are the rest of the files from the CD in a ZIP: https://drive.google.com/file/d/1KKdaUrw54sEC … iew?usp=sharing

I'm glad it could be useful, it was kind of just filler at the time. The rest of the CD probably isn't too interesting, FAQs, cable pinouts, and some common diagnostic, compress, etc apps. I'm attaching a text file with a listing of all the files

Recently getting back into retro PCs, and I recall late 90s put together a "PC Technicians" CD that included a bunch of manuals I downloaded off the maker's FTP sites. I randomly checked a few and some I found the same files already available, some I see I have other versions of, and were better …

For best DOS compatibility / quality, which is preferred? I have a Diamond Stealth 2000 3D Virge 86C325 2MB. My motherboard has SiS530 / SiS 6306 2D/3D integrated AGP graphics with 8mb + Pentium 233 MMX I'm planning to pair it with a Monster 3D Voodoo 2 card, and it will be mainly a DOS gaming PC. I …
