Hi BBC enthusiastics,

I just released the first publicly available version of Catorcio, my
Acorn Master Compact emulator.

It features:

 * 65SC12, including timing.
 * A partial system VIA (6522) to allow the emulation of memory
mapping,    EEPROM, keyboard and IRQs.
 * Memory mapping and sideways/private RAM/ROM.
 * EEPROM (8572); it's contents are stored in the external file      
ROMS\EEPROM.
 * Keyboard; it even supports typematic settings within the Master,
and    doesn't rely on the auto-repeat of the PC like all other emus I
tried    out :-) (this feature I'm particularly proud of :)
 * A very basic mode 0 or 128 (no real 6845 or ULA emulation)
without      hardware scrolling.

You can find it at "The BBC Lives!":
http://www.nvg.ntnu.no/bbc under the "Emulators" section.

Please take the time to download and try it out.
The emulator is written in 80x86 assembly and though is very compact.
If you have problems finding the required ROMs, email me privately;
Acorn are still holding their rights on them, and they are very
difficult to find on the net.

Ciao,
Carlo.
