I have a funky one that i had to make a number of fixes.
There are two speeds that give reliable reads: one a slow step stop
step, and the other fastasallheck which will literally eat the paper tape
if not handled properly "on the fly".
I have a manual obtained from the web which covers a similar unit, which
was helpful for the fixes.
The stepper motor which moves the paper tape initially was rusted /
frozen, but it seems that i was able to get it to work WD-40 plus time
then running with more soaking.
But it is too heavy to send that far; you might be better served making
one yourself.
