I recently came across some photos of an XT286 which I initially thought had an aftermarket motherboard installed due the presence of an integrated chipset. However, on closer inspection the board appears to be manufactured by IBM. Unlike normal 5162 boards it has no SIMM slots and four rows of...

I seem to recall somebody had figured out a way to modify standard 256kb SIMMs to work in the 5162. Does anyone remember the link to the post that describes how to do it?

I recently read through this thread on: comp.sys.ibm.ps2.hardware Skyrocket was the code name for an AT prototype that had 640kb on the motherboard. Does anyone know if photos of this system exist?

Upgrades 386 to a ti486 cpu.

I have a Silicon Star FU340 386 motherboard based on the PEAK/DM chipset. Existing documentation claims it supports 32MB and 256kb cache memory, however neither 32MB nor 256kb configurations work properly. I know my board is not damaged, because there are one or two others with the same board...

Looking for the upgrade that uses a surface mount TI486SXL2 chip.

This is not my auction, but as these proprietary RAM cards are very hard to find I figured I'd post the link here: http://www.ebay.com/itm/LOT-OF-4-CIRCUIT-MEMORY-BOARD-ISA-ADD-ON-CARD-FAN-CARD-VINTAGE-/251604008129?pt=US_Vintage_Computing_Parts_Accessories&hash=item3a94c47cc1 It appears to be...

How common of a problem is this exactly? Have any of you guys personally had any hardware succumb to bit rot? Should I be dumping all my old ROMS?

I would like to alter the contents of the byte located at F000:E6FA. This is where the BIOS resides. Is it possible to map RAM overtop of the ROM that exists at this locations so that programs reading it will see the contents of the RAM rather than the ROM?

I am using PC DOS 2K with empty autoexec.bat and config.sys. I am attempting to setup an EBDA (extended BIOS data area) at memory location 9FC0:0000. I am able to write the correct values into the normal BIOS Data area (0040:00XX) using DEBUG E command, but when I try to write to data to...

User Feipoa, NJRoadFan and myself have been attempting to build an adapter that allows a PS/2 mouse to connect to AT type machines without native support for such. We have already tested and built said adapter. My version of it actually sandwiches in between the 8042 and the 40-pin DIP socket...

I would like to read (and later alter) the contents of the command byte. However, I have so far not been successful. I am using instructions provided here: http://www.win.tue.nl/~aeb/linux/kbd/scancodes-11.html#kcca8 When I follow the instructions, I get 1C, which as far as I can tell is the...

I am looking for a 386 motherboard that can handle DMA, 32MB of RAM and 256kb cache, preferably with bank interleave on both the SRAM and DRAM. Therefore, something based on C&T PEAK/DM, SiS Rabbit or VLSI VL82C386 would be nice. These are usually full length baby AT sized. Oh yeah, and the...

I recently obtained an old Acer J3 motherboard with matching dual Pentium 60 CPU card. In addition to the standard AT power supply connectors there is a 10 pin molex connector which I would guess is for handling the extra load of the Dual CPU card. So far I have determined the J3 board has...

I am doing an international move and I need to clear out unneeded things from my storage locker in Missouri. All these things are available for free, with the exception that you must take EVERYTHING. I didn't really get around to doing much testing on this unit, but I noticed that the modded...
