The bios never talks to it. Official port numbers
are 3C-3F.
- Brailab4 - Same as homelab3.
- Braiplus - No work has been done. Needs to be developed from scratch.
Since it is a CP/M machine, it probably should have its own
source, once information can be found.
TM188 is (it seems) equivalent to 27S19, TBP18S030N, 6331-1, 74S288, 82S123,
