Here's a puzzler. One of the two memory boards from my PDP-11/35 is short four ICs. See: http://www.loomcom.com/projects/pdp11-35/ms11_j.jpg It looks like it was an 8KW board that was user-expanded to 16KW, and if I'm reading the switches correctly it was configured for starting address 000000. (The other 16KW board I have is configured to start at address 100000) Those four missing ICs seem weird, though. The other board is is fully populated. Were they just pulled before the PDP was trashed? Or is that a valid configuration? -Seth

NEC Spinwriter 5525 available

by iamvirtual＠gmail.com

[I hope this is on-topic; I believe the machine is at least 20 years old] I have a NEC Spinwriter 5525 printer that is available for the cost of shipping (free if you pick it up). The printer is a wide carriage and appears to have a RS232 serial interface. I do not know if the printer works or not. The machine is located in Langdon Alberta Canada (postal code is T0J 1X1) which is approximately 10 minutes east of Calgary. The machine is rather heavy. I estimate 50 pounds or more. If there is no interest, the machine is headed to the e-waste recycling. I can send pictures upon request.

Has anyone ever heard of theProtec Microsystems PRO-83?

by rdcoll＠hotmail.com

Hello everyone, I just joined this mailing list today on the advice of more than one vintage computing contact. I was wondering if anyone could tell me anything about the Protec Microsystems PRO-83 Z80 Single-Board Computer. I have conducted an exhaustive search of the Internet and found only two sites (one from a surplus store and a picture of it from a museum). I would appreciate any information available, especially information regarding the power supply and peripheral devices. Thank you very much.

Emulex UC07 / 08 and Disks greater 2GB ?

by holm＠freibergnet.de

Philips P800 family minis

by camiel＠camicom.com

Hi everyone, I won an eBay auction for three Philips P800 family minis with three cartridge disc drives, disc cartridges, lots of spare parts, and manuals including schematics. All for the incredible sum of 10 euros 75. I saw the auction when it had 11 minutes left to go while I was on vacation (I'm a bit of an eBay junkie, although deals like this are becoming rare). I'm collecting the systems this Sunday afternoon. As the manuals are all in binders, I'm planning on feeding them all through a scanner and posting them to bitsavers. Now, I seem to recall that Tony Duell has some experience with these systems. Is there anything I should be aware of before loading them on a trailer? Do the disc drive heads need to be locked in some way? When I've picked up the stuff, I'll post model and part numbers. Any advice offered on how to get them going again would be very welcome. Cheers, Camiel.

Software for OCR'ing paper tape? (was: Question about Military terminal)

Well, there are many scanners that can auto-feed a half-inch-tall pile. As for paper tape, what about the super-duper overkill of recognizing a video stream from a web cam? All you'd need is a jig to slowly pull the tape past the fixed camera. - John
