The DOS box is coming along nicely. After buying and failing with several COASt modules, I found one that worked, so the machine is now running a full 512KB Level 2 cache. I finally got hold of a CT3900 with 8MB of RAM fitted, a S3 ViRGE with 4MB of RAM, The 3Com NIC has been replaced with a gigabit Intel NIC running the E1000PKT packet driver. The leaking caps has been replaced. The noisy fans replaced with Noctua fans. For the PSU I soldered the NA-RC10 adapter directly to the PCB as there where no FAN connector. The equally noisy 1,2 GB IDE drive has been disconnected, and I am now running of a 2 GB DOM instead. I also burned a new upgraded BIOS to an empty SST29EE010-150 chip. I’ve also added a PS/2 port so I can use a more modern MX518 mouse (through an adapter). The PS/2 connector was not easy to find, as the FIC motherboard has a fine pins in a row configuration, that differs from the previous generation motherboards. I could not find the correct pinout in any manuals, so I had to test with a multimeter and change the connector.
