[cctalk] Signetics 3000KT8080SK bit slice 8080 emulator
Any interest in one of these boards? Complete except for U3, an empty 16 pin DIP socket. With some kind of transition board attached from Zapsystems, a local builder IIRC. https://archive.org/details/bitsavers_signeticsdMicroprocessor_9921635/page/n43/mode/2up?view=theater
[cctalk] Re: Burroughs TD700
Yeah with that limited set of parts I am less interested. I used to have a TD700 chassis that was modified for other uses and used the CRT monitor from a TD800 for another computer. But the Panaplex has always been tempting. I have an MT98x that I am planning to get working. Appears complete, but currently non functional. Looking for docs for it if anyone has them as opposed to reverse engineering it. Thanks Chris
[cctalk] Re: Burroughs TD700
Sorry about that; now that you mention it, I do recall you scanning and posting the docs back then. Thanks! I wonder if the fellow building one from scratch is aware of their existence... So, it looks like some or all of it is going to you; I don't think there's enough to put one back together anyway. m On Sun, Dec 3, 2023 at 4:50 PM Nigel Williams wrote: > > On Mon, Dec 4, 2023 at 8:36 AM Mike Stein via cctalk > wrote: > > ... including the > > technical manual with schematics of the cards, so at least > > documentation is out there somewhere (Tasmania, IIRC ;-) > > Shared from here since 2019...for those that missed it :-) > > https://drive.google.com/drive/folders/1iihVNRfkd_zX_PwV30gKQTNLzLcnMEvm?usp=sharing

[cctalk] Re: Burroughs TD700
I doubt it, Chris, but you never know; apparently there is someone out there more or less building one from scratch. I'm not even sure if I still have the display panel (or if it works). I sold and gave away some parts three or four years ago, including the technical manual with schematics of the cards, so at least documentation is out there somewhere (Tasmania, IIRC ;-) I'll let you know if I find the display; AFAIR it's an 8 line version. For anyone else interested, I do have two power supply/logic cabinets and the following cards: 16940801 P 16948051 C 16998650 D 16998692 H 16998734 J Without the tech docs I have no idea what they are, but for anyone needing one the info is out there. Perhaps the person with the manuals will read this and come forward; I don't believe they've been scanned. m On Sun, Dec 3, 2023 at 3:08 PM Chris Coley wrote: > > Why are you scrapping them? > Are they generally complete? > > If there is enough to refurb into a unit I am interested.

As part of this, I bought some SCSI2SD boards, and got one working in my VAXstation 4000/90. I planned to do the same with the VAXstation 4000/60 I have in a rack, but it’s still running off of a rack mount BA350, and a couple old SCSI drives. I should probably look into what it would take to put a SCSI2SD board in a SBB. I need to find time to work on my PDP-11/23+ and PDP-11/73, as I’m sure I need to replace the caps in the Powersupplies, so I haven’t tried to drive a SCSI2SD board with a Viking QDT. Zane
