        Years ago I had heard rumors of their being a way of running
CP/M on the drive itself with the onboard Z80 but I was never able to
get any concrete infomation on it and I never bothered to open one of
them up, since both of mine do work, to verify that they had a Z80 as
part of the controller.

        Yes, those are the platforms that I recall seeing them for.
 From the outside, they appeared identical to me other than the I/O

        I didn't know that Rana and Indus were one and the same.

        That's pretty cool. Regardless of just how well it worked,
it'd be interesting to see it done at least once. I wonder if the
console I/O was directed to the screen I/O of the Atari 8bit?

        The 810 I like, especially with the additional speed of the
Happy upgrade. Without it, the 810 certainly is a slow and noisy
beast! The 1050 I've never been a big fan of, though none of mine
ever got upgraded to true DD.

        Does Bob still do anything? Other than in conversations
about his older stuff, I've not heard his name mentioned in a while.
