Details
Currently running MS-DOS 6.2 and Windows 3.11 for Workgroups.
I plan to do a fresh re-installation of Windows on this machine and potentially remove the network card since it now has a ZIP drive that I can use to very quickly transfer data.
Four zip disk transfers would easily fill the entire drive of this machine.
GW205 V2
When I received this machine, it had a dual gameport ISA card in it, but it did not appear to be functional.
It is marked as a "GW205 V2" card but I am unable to find any information about it at all as it lacks a manufacturer mark, it has no EEPROMs and no processor.
It consists of:
- 1x HD74LS244 (Octal Buffers) linked to a resistor pack for those lines
- 1x HD74LS32P (Quadruple OR Gate)
- 1x HD74LS138P (3-Line-to-8-Line Decode/Demux)
- 1x NE558 (Quad 555 Timer)
It seems to be using nothing but pure TTL logic chips to read the gameports and drive the ISA bus.
