Virgil Dupras	953e040231	emul/z80: add AT28 EEPROM emulator ... This will facilitate the development of a solution for cross-compiling directly to EEPROM.	2020-12-08 20:07:53 -05:00
Virgil Dupras	1e8f957910	emul/trs80: implement floppy emulation ... So far, only the first 400 sectors of the disk image are accessible. TODO: add keybindings to swap floppies on the emulated machine.	2020-12-06 19:52:18 -05:00
Virgil Dupras	23885dac33	emul: add TRS-80 emulator ... Not complete yet, but has @KEY and @DSP, enough to get prompt.	2020-12-05 22:04:22 -05:00
Virgil Dupras	97a46a7b9b	emul/z80: decouple SDC and SPI ... My idea of plugging a RC2014 bridge directly onto a Sega Master System cartridge doesn't work. The SMS eats all I/O addr space, we can't use it. Therefore, this naive idea, in the emulator, of reusing sdc.c in sms.c as-is, doesn't work either. I'll have to find another way of communicating to a SPI device on the SMS. I'll probably do it through a controller port. Meanwhile, I need to decouple SPI from SDC in the emulator code so that I can reuse sdc.c. This is what is done here.	2020-10-29 15:01:25 -04:00
Virgil Dupras	efe4b13a4e	Move /emul to /emul/z80 ... I'm planning on adding other subfolders. 8086 for example...	2020-10-24 16:50:22 -04:00
