1500, 1550 and 1560 appear to be the major models, they are supposed to all run DOS.H
I have a few issues of "Source Data" from 1981 and 82 that I'll be putting up on bitsavers later today
that mention the announcement to the 1550 and 60. I think the models after the 1500
have a 4MHz processor and can support more than 64k of memory. Hardware wise the 1500
and 1551 boards I have look very similar, there is more firmware on the 1551 board
and it has a faster clock oscillator. I think they mention the later models support
double-density floppies.
