Subject: Keypunch that was on eBay
Thanks for whoever it was who posted the info on the IBM 029 keypunch
on eBay. I have won it, nobody else bid. After it has been shipped
across the Atlantic I will have to think about converting it from 60Hz
to 50Hz. I have the remains of a 50Hz verifier which has a 240v / 50Hz
motor I should be able to use. Hopefully the rest runs on DC, so a
step down transformer before the transformers and bridge rectifiers
might be enough. Shipping costs more than the item of course.
Anyone have any thoughts if it is worth trying the whole thing with
just a 240 - 110 transformer? If the motor burns out, not the end of
the world.
We used to have motor-generator sets for running 60Hz IBM stuff off 50Hz
supplies. ISTR it was important for some timing function or other (we are
talking 9020 here, and it was scrapped shortly after I joined the company).
Jim.
