-
- Homelab driver by Miodrag Milanovic
-
- 31/08/2008 Preliminary driver.
- 15/06/2012 Various updates [Robbbert]
-
- The emulator called HoLa! works fine, but it is closed source.
- You can get HoLa! at: http://gaia.atilia.eu
-
- ToDO:
- - HTP files should be a cassette format, not a quickload.
- - Quickloads cause the emulated machine to hang or reboot.
- - homelab2 - cassette to fix.
- Note that rom code 0x40-48 is meaningless garbage,
- had to patch to stop it crashing. Need a new dump.
- - The speaker code is wrong, but it's the only way to
- get any sound. Needs to be looked at again.
- - homelab3/4 - Need a dump of the TM188 prom.
- cassette to fix.
- up to 64k ram can be fitted. schematic only shows 16k.
- Z80PIO - expansion only, doesn't do anything in the
- machine. /CE connects to A6, A/B = A0, C/D = A1.
- The bios never talks to it. Official port numbers
- are 3C-3F.
- - Brailab4 - Same as homelab3.
-
-
-TM188 is (it seems) equivalent to 27S19, TBP18S030N, 6331-1, 74S288, 82S123,
-MB7051 - fuse programmed prom.
