I have a number of *ancient* 8080 programs that were ported to CP/M and then abandoned in the CPMUG disks to die. Some of them would be... almost useful on a WP2. There's an intriguing calculator, and several small BASICs, and of course my personal obsession, FOCAL.
Any of them (even FOCAL) would be a step up from what's now available, which is nothin.
Not that I've got the time, but it's fun to think about. And this question had me roadblocked.
