see Architecture at PDP-1.
from Max Burnet
[This] is a hardware bootstrap loader for the PDP-9. Made by Tennecomp with a 19 inch rack form factor. It has a large black motor, which is activated by pressing the button on the front panel. The motor rotates a studded drum, 18 studs wide, and 60 positions long, using 53 of them. Like one of those music boxes.
The connector on the back of the unit would have been cabled into the PDP-9 (I presume) to pretend it is a "fast" switch register. I don't have any doco on the unit or know where it plugged in.
I was given it about 20 years ago by CSC Aust who had a PDP-9, and I believe it was in use. Would sure beat toggling in fifty three 18 bit words.Cheers Max Max Burnet Director Burnet Antique Computer Knowhow (BACK) Pty Ltd Address 138 Boundary Rd., Pennant Hills NSW Postal PO Box 847 Pennant Hills NSW 2120 Australia Phone 02 9484 6772 (diverts to mobile) Mobile 0412 124 006 Email firstname.lastname@example.org Web www.acms.org.au/a102.htm
