Needed: SDI disk

by b4＠gewt.net

Afternoon all, I need an SDI disk to test my MVII...largely to see why my KDA50 always shows up as "offline" to VMS despite correct CSR and why I can NOT boot VMS over the network...I always get a machine check or a DBL ERROR. Small enough to hold 4.3BSD-Quasijarus should suffice for testing purposes. If you're not willing to part with one for <$75 (price of an RA72 on ebay) I can return it or work out a trade. Thanks! I want to get all the tests on this KA630 done. -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects

Any Interest in a 1985 Wang Office Assitant

by crankeye＠gmail.com

I have 1985 Wang Office Assistant and I'm looking to see if anyone would be interested in the working unit and accessories. The unit works great and the printer still prints. I have: -Main Unit -Monitor -Keyboard -Daisy Wheel Printer w/ an extra Ink Ribbon -Manuals -Software -Paper Trays I'm based out of Phoenix, Arizona and would be willing to ship to the US only. Though it may be expensive to ship considering the printer alone is a good 20-30 lbs. I can provide images of everything if there is any interest. Thanks, Neal

[Fwd: Restoration of a PDP-8a]

by anders＠abc80.net

Hi, I have started restoration of a PDP-8a model 8A420-CN. I doesn't have any schematics for this machine and I have searched internet for sources without any luck. The sets on http://bitsavers.trailing-edge.com/pdf/dec/pdp8/pdp8a does not include my version. My machine came with 16K*12bits core memory, 20 slot backplane and only the "Limited function board" frontpanel (don't now if this machine ever had the "Programmer's console"). This is how my "Power distribution board" looks like: http://www.abc80.net/docs/pdp8/pdp8a/DSC_2118.JPG Some questions: 1. Is there anybody that could help me with schematics on this machine? Scans are preferred, but I can pay for paper prints. I'm especially looking for a diagram that matches the "power distribution board" that I got. 2. If I plug in the machine with only the regulator boards (2xG8018) and the limited function board in it, should the lights and fans come to life? 3. I suspect that my model shouldn't have "Power distribution board control", G8019 since my "Power distribution board" misses the connector for this board. Can that be correct? Any help is appreciated. PPD-8a is new to me, but I have some knowledge in the PDP-8 architecture since I restored a PDP-8/L that was in really bad shape. /Anders
