Does anyone know of a source of extremely cheap (n <= $30) single board computers a la ZX-81s for use as dedicated controllers around the house ? I have a few projects in mind but don't want to put the time into them unless I have a few of these SBCs so when I fry/lose them the projects aren't worthless anymore. rcs

It comes with 64K of RAM, a monitor in ROM, a disk controller, CRT display circuitry, etc. It is a CP/M machine and was heavily supported by Microsystems magazine for a number of years - lots of tech info.
