It's one of those "someday..." things. My Heathkit H8 and H89 computers both support both octal and hex displays. The H8 uses two different ROMs (2K each). The H89 has a bigger ROM (4K) that has a "radix" command to select octal or hex.
I was thinking of a SD card for program storage under cp/m, but now
realise your design objective for this computer to be truly retro, so
'cassette' storage is required.
It's not required, but it's there for that "vintage feel".
However, the Altaid's RAM has battery back-up. You initially load it via the serial port (from a PC etc.) Once it's loaded, the battery maintains data even with the power off.
Looking forward to the kit being available soon.
So are we! :-)
