Google turns up very little specific information on either of these devices,
e.g. nil return from bit savers. The best leads I have are:- The UTR 700 was
badge engineered by Ferranti into FM1600B systems, one of which fetched up at
the Centre for Computer History, Cambridge, England; perhaps with
documentation. Also, as it was used in government systems some maintenance
documentation may have fetched up in the PRO, at Kew.- Some Facit 4060
documentation, for the 4060, its 4061 & 4063 chums and the 5106 interface, look
to be lodged in Box 52 of the ICL Collection at the Science Museum Library. The
UTR 700 reader looks to be parallel interfaced, 10 single ended outputs from an
interface card. The jokes start with manufacturer codes, rather than OEM part
numbers on the 14 pin DIL ICs. However, a little scope work should identify
tape out, data 0..7 and strobe lines. More interesting questions are
lubrication and capacitor replacement - where a schematic would be a great
assistance in deciding how to proceed. etc etc The Facit 4060 punch contains
no more than the electro-mechanical mechanism : AC drive motor, solenoids and
rotary position sensors. The 4070 documentation (on BitSavers) may read
across, in terms of sensor characteristics, solenoid operating voltages and
snubbing needs, or it may not. That reconstructing the schematic would be
straightforward simply identifies how much is missing, and the difficulty of
specifying it in the abscence of documentation. A classic tape punch interface
from data latch and ready, through position sensing, solenoid drivers and done
logic is required, together with auxiliary indications, e.g. tape out. etc etc
Any information, wisdom, documentation or pointers to sources would be very
much appreciated. To state the obvious, I was passed these devices by Philip
