Hi,
I also have a real TXED manual....
Yes, we had one at school....just the one so I don't have it.
....And an original ZASM manual (an A5 size booklet).
And
something on a 'Local viewdata system' which I've never
seen the software for.
Never seen a ZASM manual. What's this "Local Viewdata System", I've
never
heard of that?
....other hand is does include support for a beeper in
the keyboard
casing, which the 40 cloumn one does not.
We were going to have a bash at wiring that up at school, but we never got
around to it.
Most _audio_ machines kept the remote control on a
different
connector from the audio I/O. Remember that normally plugging
something into the remote control socket opens an internal
switch, stopping the recorder....
....'audio' connector, you'd need to have a special audio cable
with those pins shorted for normal audio recording/playback.
ISTR the machine I was thinking of (I think it was a "Waltham") had a spring
loaded plastic peg in the socket, which was pushed aside by the DIN plugs
metal shroud when inserted. This operated a small switch inside the machine.
However, the more I think about it the more I wonder whether that
arrangement muted the internal loudspeaker rather than allowed for remote
motor control.
....Of course the Acorn data recorder did have all
connections on a
7 pin DIN socket (so you could use a straight-through cable to link
it to a BBC micro IIRC). But that was a rather specialised machine.
Is that the same recorder which was designed to match the case shape of the
"Electron" or another one?
I got one of the "Electron" shaped ones with my "Interak", I've
never tried
using it.
There is mention of 'switching it to
'single'' if you only have
one recorder. Maybe that's the switch in question. It also mentions
that the remote control is handled by a separate jack plug.
Yes, that's what my copy states too. It's got to be my memory, but I just
don't remember that "remote" lead.
Ditto... No mention of how to add motor control
either...
Mine just says that you have to use an external relay....sigh....
TTFN - Pete.
