Building an 386 system

Sooo, finally I've put together 386 system that I've got from a guy that was cleaning his garage and getting rid of this machine. First of all I dismantled the whole computer and cleaned the housing. After that the battery on the motherboard was removed, because it was leaky. Electrolyte fortunately haven't done much damage so I've only had to clean the pcb.

After that I've soldered a new battery and put everything together. Although the motherboard has normal ISA slots this housing uses a riser card. This card is plugged into one of the 16 bit ISA slots and offers two 8 bit and three 16 bit ISA slots.

At the current moment the spec of this machine are: 386DX-40 and 16MB RAM. The graphics card is a Trident TVG9000 with 512k of RAM. In the computer you can also see SCSI controller. It's an AHA1540B with 50pin HDD interface (SCSI-1 and SCSI-2 compatible) and with 34pin FDD controller. Also in one of the 8bit slots I've put an I/O controller with serial, paralel and game ports - what a convienient usage of these ports. I still have to connect the floppies and HDD in order to install anything on this machine. After that I have an Scientific Solutions board ready for that PC. It's an 96 digital I/O card. I hope to run some parallel feed digital-to-analog converters on that.

As you can see I've added an second page for my blog called Inventory (see top). I plan to put there all the stuff that I have at home. At the current moment only some of the computers are fully described, the rest is waiting for the description or to be fixed/completed/put together.
