[Coco] OS9 68K, MM/1 software and questions

[L. Curtis Boyle]

I know that Chris Burke did a version of RSDOS/BASIC for the TC-9 (it was a separate boot disk from the “normal” OS-9 and NitrOS-9 ones), but I didn’t run it too much (and it was a bit unreliable on my system, since I had bumped the clock speed from 1.78 to 2MHz with a clock crystal replacement, and hadn’t bothered trying to patch Chris’ code to slow down disk routines enough to make it fully reliable).
So, in that sense, the TC-9 was a “Coco 4”, although said BASIC (and OS-9) did need some patches for the 8 bit joysticks, and 8 bit sound.

So programs written in C for the CoCo could be ported to the MM/1 very straightforwardly.  So there was a degree of source-code compatibility there.  Had there been more GUI programs written in C for the CoCo 3 in the first place, there would have been more ported to the MM/1.
