Triumph-Adler (or Royal) Alphatronic PC
Skeleton by Barry Rodewald and Robbbert, filled in by R. Belmont
Driver by Barry Rodewald, Robbbert, R. Belmont and Carl
z80 + HD46505SP as a CRTC
Other chips: 8251, 8257, 8259
Crystals: 16MHz, 17.73447MHz
Floppy format: 13cm, 2 sides, 40 tracks, 16 sectors, 256 bytes = 320kb.
FDC (uPD765) is in a plug-in module, with an undumped rom.
FDC (uPD765) is in a plug-in module, there is no ROM on the module.
A configuration switch determines if the FDC is present.
Has a socket for monochrome (to the standard amber monitor),
and another for RGB. We emulate this with a configuration switch.
ToDo:
- Add fdc, then connect up software list
- Newer ROM set from Team Europe and try to work out the graphics expansion
- uPD765 oddness that prevents Disk BASIC from loading
