Hi
Ok, I have to through this in as well.
It wouldn't do much for hardware but still fun for software.
Get a Canon Cat. It can be easily expanded to 512K
and even more if your interested in regenerating the EPROMs
code ( such a writing your own printer driver for your
favorite printer ).
One can use the built in editor to write your code and then
either compile Forth code or assembly.
One can play with bit mapped graphics ( B/W only ).
One can even fiddle with disk formats.
It is just not that interesting for fiddleing with hardware.
Most of the interesting stuff is in ASICs.
