CMT _might_ be a for a cassette recorder. Firstly that would be an
'expected' interface on this sort of machine, and I think I've seen a
similar label in some Epson or Sharp manuals
It would be unusual to have RF on a DIN connector --
I'd expect composite
video, or maybe separate video and sync. How many pins are on this
connector? And are there any connectors (again, how many pins) on the
C-CRT board?
Tony, if you can't view the JPEGs that Sellam put up, I can tell you that
they show:
the L-PEN socket is a 180-degree 5-pin DIN
the TV socket is a 6-pin DIN
the A-CMT socket looks like an 8-pin DIN (same form factor as a 7-pin DIN)
the RS-232C socket is a DB-25S
the socket on the back of the FDD card is a 34-pin 3Com header, like the
ones on a Beeb
the socket on the back of the C-CRT card is single-in-line 18-pin
connector, looks like about 0.1" pitch, male pins, green shroud with male
pins, keyed by having cutouts in two corners (in the same way a 64-pin DIN
header is keyed) -- I can't remember what these are called but I've seen
them before.
