A 486 motherboard with a DX2 66 on board. An IDE controller for two hard drives and two floppy drives, as well as a 2xCOM, LPT and game port are also already on board.

Simple ISA card with space for a 27C256, 28C256, or 28C64B (U/E)EPROM. The 28C*** EEPROMs can be programmed using the card. This card can be used, for example, for the XT-IDE BIOS, XT-RAMTEST, or ROMOS.

Simple ISA card with space for a 27C256 type ROM. The EPROM cannot be programmed in-system; a programmer such as the XGecu T48 is required for this. A UV lamp is used to erase the ROM.

Another XT IDE controller, with a Compact Flash slot, which is accessible from the back of the computer with the correct slot bracket. The board is built with through-hole components, with the Compact Flash slot being the exception. Therefore, the board should be easy to solder.

Should an IDE hard drive be connected to an old XT computer, or is a larger hard drive needed for the 386? Can a BIOS be „easily“ rewritten or should the computer be replaced with a newer one? Since neither is usually an option, fortunately there is the XT-IDE project. Now the XT computer can be fitted with new hard drives...

I don't know why ScrapComputing always makes a "blaster" out of its projects, but they are all helpful. The ISA Blaster is an ISA board with a USB port for a mouse. Plug it in, install the modified driver, and it should be working. Great, right? A modern optical USB mouse on old hardware, I have to try it, I...

I was almost beside myself when looking for a Rise card for measurements on a running PC or to be able to operate the DIP switches without removing the board. The simplest 30-year-old hardware is being hawked at exorbitant prices. It should also be noted that some of them are equipped with proprietary connectors on the board. The...

A 386DX40 motherboard with space for a co-processor, which in this case is also fitted. 8 SIMM slots allow up to 32MB of memory to be addressed. 128KB of cache is very generous for a 386 board. The board looks very tidy, all ISA slots are 16-bit. Let's see how the performance looks. ...

Now I also have a 386DX40 on an MSI motherboard. The motherboard had battery damage and, judging by the snipped leg pair, likely a shorted tantalum capacitor. The damage to the DIN socket for the keyboard has already been repaired with two jumper wires; the board works perfectly. This invites me to do some tests. …

8-bit ISA network card with 10Base2/5 connection. Unfortunately, it can only be operated in the combination Address 0x280/IRQ3 or 0x300/IRQ5. Software configuration did not work for me.
