With the 102 operational I have been testing peripherals with the
machine. Cassette recorder CCR- 81 reads and writes under control of
M102; printer DMP-105 now operational after cleaning and relubing,
including ribbon; bar code reader (Cat 26-1183) problematic.
I have a couple of questions; perhaps the members can assist:
- The printer documentation does not mention a control code for Form
Feed or TOF Set, and LPRINT CHR$(12) does not work, nor does CONTROL-P,
CONTROL N from within TEXT. Does anyone know of a way around this?
- The ribbon cart is unique, to say the least, and I only have one.
So far I can't find a source; again, any suggestions?
- The bar code reader has been sitting around since I bought it from
RS as a closeout years ago. I'm able to load the software from the
cassette provided but when I actuate the "wand" I get no input. The LED
in the tip of the wand seems to me to be very dim and doesn't get much
brighter when the "button" is pushed. I think this is a voltage problem
but I don't have any specs for either the VOUT on the M100 (pin 9, VDD,
according to the Model 100 manual) or for the wand itself. But I may be
missing something, so if anyone has experience with the device, please
advise.
The wand interface is a standard called "laser emulation" or "wand
emulation", not just for the M100/102

Compare that with the M100 service manual page 4-11
You can go on ebay and search for "MS120 1D Laser"
and find ones like this:

And that works.
"sqeeze" just refers to the retainer clips built in to the 9-pin plug.
Careful there are several variations of MS120. The laser/Wand Emulation
version is just one.
VDD is the same VDD as the rest of the machine, +5v
return signal is the same, ie ttl.
You can use oil-based stamp-pad ink to re-ink the ribbon, until it
mechanically wears out from the beating. (not wd-40!)
Stamp-pad ink also comes in water/glycerine-based, so make sure it says
oil-based explicitly, or else keep looking for one that does.
