I suspect it'll be considerably faster than the ASR33 too ...
I'm counting on that :-)
There are very few punches that are only 10cps :-). Even the small
stand-alone ones seem to be about 30 cps, better ones around 50-75cps.
I don't know yet which style it is as I have not
opened the unit up.
But, lacking the docs at this point, that is the next step.
Perhaps it's just me, but I always pull the case of _anything_ (new or
old) and have a look inside before applying power. And if possible check
PSUs on a dummy load and trun mechanical parts by hand just to check for
It does correctly punch the feed holes and will appear to do so all
day long. It's only when I press the button with the big black dot
that it attempts to punch all eight holes and stalls. The feed hole
punching screws up then too.
This does sound like the PSU is getting overloaded having to power all
the solenoids at once. It may be something as simple as a dreid-up
smoothing capacitor, although without knowing anything about the design,
it's hard to be sure.
You may find you can disconnect the punch solenoids (leave the feed hole
one conneted). At which point your 'code holes' switch (as Facit call
it), should just punch feed holes. And then maybe reconenct the solenoids
1 or 2 at a time and see what happens.
