Karabas-Nano is a ZX Spectrum compatible machine with a real SMD Z80 CPU and all the logic in an Altera EPM3256ATC144 CPLD (or EPM7512). The idea was to make the cheapest and smallest clone with a minimum of components, and to learn KiCad along the way.
Some parts of the schematic come from Karabas-128 and ZX-UNO.
Two configurations
The board has an SD card socket, and it works with at least two firmware configurations:
| Z-Controller | DivMMC | |
|---|---|---|
| Timings | Pentagon | Pentagon |
| ROM bank 0 | GLUK reset service | ESXDOS 0.8.7 |
| Memory | 1024 KB, port #DFFD (Profi) | 128 KB |
