I've got several old printers (and an ASR-33) that need ribbons. Thanks, Bob

Whatever it is, one way to approach it is to make a dummy load for the PSU which resembles the normal load on it as far as possible. If the PSU continues to malfunction when feeding only the dummy load, the problem is almost certain to be in the PSU itself. Dummy loads for low voltages can often be made from bulbs for use in cars, including dual filament bulbs which had to be replaced because one filament failed. Another useful thing to do is to look for bad connections in the PSU. If it is constructed on a printed circuit board, while feeding the dummy load, try examining the underside of the board in a darkened room while tapping the board with something insulated. You might see or hear tiny sparks indicating the location of a bad solder joint. Be aware that the PSU probably contains high voltages and that these may remain for a considerable period of time after power has been removed, particularly if the unit is faulty. Regards, Peter Coghlan.

Exidy Sorcerer available in Australia

by nospam212-cctalk＠yahoo.com

Was contacted by the person below looking for someone in Australia interested in an Exidy Sorcerer. Passing along here. Contact the person below. I would be interested in possible copies of any doc or such which I don't have for my Sorcerer if someone picks this up. David Williams www.trailingedge.com ----------------- I am in Australia. Do you have a contact here that would like to have it for collection or museum? it WAS a 48K memory version but in later years of use the memory dropped to 32K - presumably a meory fault or dry joint somewhere. Unfortunately, I cannot tell if it is still working, because I have lost the connector cable for the video to the modified TV which Dick Smith electronics sold with it. I also have about half a file drawer of documentation related to it and related matters. Cheers... Keith Dyson ph 08 9457 8913 (inside Australia) or email keithdy at iinet.net.au (preferred)-----------------

8mm Movie to Digital Service?

Look around for a coupon / Groupon, they do have discounts and frequent promotions. I think this digital scanning of old film is entirely apropos for computer preservationists. Many early computer animations were recorded this way. It seems like many film-to-digital conversions happened by way of steps that involved NTSC video. That's a shame, and reminds us of the lesson of the value of keeping the original material. - John

I remember when I was doing my thesis, I printed it on the department's Qume daisywheel printer. They had the service manual with complete schematics. It was very interesting, with analogue servos for the carriage motor. A very nice piece of equipment. Not to mention the 11/40 we used, or the big 80 MB Ampex disk drives. /Jonas
