eBay strikes again!!

by Bill Gunshannon

Just when I thought eBay couldn't get much stupider... I went out to see if I could find a current going price for PDP-11 Pedestal Boxes as I have a couple I would like to cull from my collection. I came upon this: DEC PDP 11/23 - BC needs Power Supply Repair, NO cards, Vintage DEC History $900.00 If it has no cards, what makes it a PDP-11/23 other than the paint on the front cover? Dead PSU? Looks like a $900 backplane to me. And that is making the assumption that the backplane is actually usable. :-) bill

DEC backplanes

by Paul Anderson

I've been digging through a few shelves of backplanes looking for a specific one for a listmember. Along with the DD11-CK and DKs, I found a RK611 and RH11. I probably have the boards for both. Any interest? Also found a few DDV11-D which I think is a 6x9 hex qbus backplane, but it's been a while. If you need any backplanes (11/84, 11/44) or options (DR11-B, etc) now is the time! Also a lot of core memory and backplanes. Please contact me off list. Thanks, Paul

Tadpole Sparcbook 2

by Andreas Holz

Hi all, by surprise I got a Tadpole Sparcbook 2 some time ago. Sadly there seems to be almost no documentation available in the net for a Sparcbook 2, neither a technical/service nor a user manual, only for Sparcbook 1 and later models. I do have the following issues: - the battery pack is missing. I found two ressources, e.g. the CHM - but none does have any infos about the battery pack - The external power connector requieres 18V - no problem - After connecting the fitting power the Sparcbook does power up, the display is lit and the unit is trying to boot from the internat SCSI disc. Nevertheless the boot process is failing this is a good sign. - after trying to reboot the unit will be almost dead. While pressing the power on button the LEDs on the left upper side of the display will be lit shortly, but nothing else will happen. - trying to reboot an power on the same as above will happen If I'll keep the unit several weeks/months unpowered the unit will power up again - but of course will be stuck again while trying to boot from disk and the same semidead issues as noted above. I'm suspecting the TOD chip/battery is deads or are there any other sugegstions? Up to today I didn't have a look inside of the unit ... Does any have the manuals hidden in theirs shelves? Best Andreas

Re: Bill Atkinson

by John

In addition to everything already cited, he developed what is still my favorite dithering algorithm. Atkinson dither was probably optimized more for speed than anything, but I've always loved the look of it, and have even implemented it myself for that reason. R.I.P., sir.
