MAME: Acorn System

Postby Pernod » Fri May 18, 2018 10:40 am

As there are no other System emulators out there I thought it was time MAME supported them. The System 3 with 6809 CPU has been in MAME for many years so I've added the 6502 and 6502A CPU boards for the System 3, 4, and 5. The System 2 is not working as the COS ROM is MIA.

Support for the following boards is included:
- 32K Dynamic RAM Board
- 16K Dynamic RAM Board (half populated 32K board)
- 8K Static RAM Board
- Cassette Interface Board
- Econet Board
- Floppy Disc Controller Board
- 40 Column VDU Board
- 80x25 VDU Board

System 5 running New BASIC from floppy:

Each Acorn Bus slot is configurable:

Nice job Nigel....

What does the econet emulation do, can you connect emulators through internet?

Excellent, I'll have to give you details of the 1770 based floppy BIOS that I have developed for it then maybe that can be added as well.

Cheers.

Phill.

Not very useful, just connects to an emulated Fileserver like the BBC machines do. Never used or understood econet so it's never worked afaik, may be a MC6854 emulation issue or just needs a clock.

Sure, if it's intended for use with actual hardware then I'll add it.
