It seems the board has a Tseng ET1000-A adapter - it makes for an interesting display piece, as I allready have an ET2000 EGA card as well as the common ET3000 and ET4000AX VGA cards. Maybe I'll build a small display case and put these in it. I have this card NOS with manual. In case you need it I …

Yes they are very nice ! If that CT1740 manual is the full one with the jumper settings for the CT1740 you should take pictures of the pages and make a PDF. If it is just a basic SB 16 manual then no need as they are common I did similar for the CT3930 "jumper set SB-32" because the original …

Anonymous Coward wrote on 2022-11-24, 15:19: The second card is probably not OLB. It just seems to be a CPU card that shares the same connector type. You can see on the motherboard the slot that says "for CPU module only". It is CPU card. Showing the motherboard without this card wouldn't make much …

Good info! I ordered some time ago sime double 2032 holders... I modded one for the 386 with two diodes and a resistor to bring down the voltage closer to 4-5volts... Do you think I could go without this? Maybe only a diode to stop current going into the cells? A diode is enough for EXT_BAT with …

nice big collection, it looks like some1 butchered the socket on the non working last board at the bottom, im curious most of the boards have batteries removed except like 3 that have the green barrel still attached Yup, fresh batteries I soldered in place of the old, desoldered ones. I simply used …

Good old stuff. I have an Amiga 500 to 286 PC emulator board by Vortex at that time, placed 2 parts to the midst of Motorola 68000 CPU and an Amiga chipset. Hmm was it an AT or XT I don't remember now. It works at ohhh, 16 or 20 MHz something, without a co-processor. It can managed to run PW …

Checked... but cannot figure where does pin 22 of the KBC go... The pin of the socket on the back side of the board is a dead end... that means it should be on the top of the board, but also cannot see it go anywhere... Now... or is the path hidden under the socket, or is the PCB a multilayer board …

I have the exact same problem as you had "Gate A20 ERROR, 8042" on a AMD 386SXL25 motherboard. It's battery badly leaked, so I am still in search of eaten via's, but for now everything seems ok. Been searching on the internet how the KBC (intel p8042ahp) and buffer connect (SN7407N) but not a …

I don't know of if this is of any help, but I remember hearing about some external video processors that could rotate and/or mirror a picture, you'd just plug it between the source and the monitor. There's a few companies that made them, but the ones I heard about the most were the Silicon Optix …

You were always supposed to use rotation feature in the video card for that, which will not help with DOS etc. stuff, only Windows and only when your video card is new enough to have this capability... Well, that's not the answer. You were never supposed to use HDMI for DOS gaming as well, yet here …

This is a tantalum close to the power supply connector on the MB. In my case, the power supply was in good condition. The MB had a cap that was shorting a rail. Well, I guess he can tell if the PSU is shot or not - if LEDs go shiny and HDD go spinny then it's likely OK. If Nothing happens when the …

Good chance it's only that capacitor given my experience. If caps are dead then very likely also other components (voltage regulator, diodes) are bad. If just caps are dead then PSU at least tries to work (ie. it gives some voltages but usually way too low, if caps are dead in the high voltage …
