After a nasty bug involving the reset line on the CF card adapter, the #Z80 #MC6847 computer is working again. NASCOM #BASIC is the first complex assembly program ported to the platform.

Expanded breadboard for #Z80 #MC6847 computer. Keyboard interface is on the bottom row (PS/2 connector, ATtiny85, SIO). CF card to IDE adapter was connected using jumper wires.

New additions to #Z80 #MC6847 computer: ATtiny85 and SIO for keyboard input, and CompactFlash/IDE interface for disk access! I got to the point where I can type DIR and see the root directory of a FAT16 formatted card.

The #Z80 computer is finally working. 8KB EEPROM, 64KB RAM, with switchable 8KB video RAM for the #MC6847. The tricky part was isolating the bus with 74LS245's, so that Z80 and MC6847 can talk to each other via the video RAM.

I have used a 74HC4053 (analog multiplexer) to switch chroma signals by software. The #MC6847 is a colorful chip indeed.

Impossible colors with #MC6847: I was rewiring the circuit and accidentally switched chroma-A and chroma-B. Now one color set gives orange, yellow, blue, cyan, and the other color set gives buff, blue, magenta, green.
