I believe both
units were made long befroe there _were_ CF or SD cards,
so I don't see how they could have used them :-)
They were, yes, but then
again, there are SD and CF interfaces for
earlier devices such as the ZX Spectrum now, so it is doable.
Both have RS232 ports, don't they? Surely you
can get text off them that
way?
As I said - an /easy/ way to move data. As I have said before, to your
bemusement or incredulity, I really detest RS232 and have done for
about 25 years now. [...] I really like USB for this.

Ignoring parity, does it send octal 033, 175, or 176 (hex 1B, 7D, or
7E)? And do you want to know that with regard to ASCII X3.4-1963, or
USASCII X3.4-1967?

I would propose, as an immutable standard medium for
cctalk-relevant
micros and some minis, neither SD, nor CF, nor USB.
I would propose 110 Baud ASCII via 20mA current loop.
Well, the covneresion for those people who prefer a votlage-level
itnerface is pretty simple (a couple of opto-isolators and some
discretes), so yes, seems reasoable...
