P112 pre-order deadline

by dgriffi＠cs.csubak.edu

The deadline for pre-ordering a P112 kit, October 11, is approaching. I need to have 35 pre-orders before I can go ahead and have the boards made. I've only been able to pre-sell twelve kits. If I can't get 24 more kits sold by then, I'll have to cancel the project. I don't have the spare cash to finance the project entirely on my own. For those who are curious: I set the cutoff to October 11 because that's 60 days after the first order was placed. I can refund Paypal payments and get the fee back only within that window. The minimum of 35 pre-orders was chosen because for that number, I'll have the money to have 100 boards made and get parts for 35 kits. From that point on, the process becomes self-sustaining. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?

Spec of Memory for a DEC Alpha 433au

by robert.jarratt＠ntlworld.com

I am trying to work out what kind of memory to look for to fit in my 433au. I can see it need 168-pin ECC SDRAM, but I am not clear if it can be unbuffered or if it must be registered and whether I need PC100 or PC133. I can also see that the notches on the side to hold the DIMMs in place seem to be higher up than on most of the DIMMs I can find, not sure if there is a particular technical term I should include in my searches for this. Can anyone tell me the required spec? Thanks Rob

Anyone have docs for a Digital Engineering Retro-Graphics ("VT640") board?

by ethan.dicks＠gmail.com

Hi, All, Jack Rubin sent me a Retro-Graphics upgrade board and cage that seem to have had an unpleasant interaction with mud daubers (I only have the boards, but the report is that the PSU of its former host did not survive). I'd like to clean an resurrect it, and I'd like to find any tech docs to go with. The closest I've found so far is a manual on Bitsavers for a version of the product for an ADM-3A terminal: http://computer-refuge.org/bitsavers/pdf/digitalEngineering/RG-512_Users_Ma… I found a query from John Wilson (D-Bit) some months back where he's seeking a programmers' manual, so it appears there are more questors than answers. Does anyone have anything on this device? It's a DEC-quad-height-sized card, with connectors appropriate for a VT100 enclosure, a few cables (PSU and data to/from the main VT100 board) and a metal cage, possibly just the standard DEC cage from a VT100. I think I can see how to plug it all in, but beyond cleaning and checking for dead shorts, I'd like to know something about it before I apply voltage. Some very nice photos can be found here: http://www.fairlightcmi.com/VT640-board-set-eBay-photos.html Googling has so far only returned references to its use with the Synclavier II synthesizer (and its modern replacement, a "VT640" emulator for MacOS X) and various science and engineering apps from the heyday of VMS and dumb terminals. No technical data beyond a few control sequences. I know how to drive a Tektronix 4000-series graphics terminal (and have some nice Tek files from some recent research on my Tek 4105), but I'm really looking for hardware docs more than just lists of command sequences. Thanks for any assistance -ethan

I have a User's Guide for the "IKOS Systems AT Host", which is apparently a logic validation system. It happens to be in a binder labeled Graphics Plus GP-220 from Northwest Digital Systems. Both are in good condition. If either of these items is of interest, make me an offer to keep it from the recycle bin. Shipping will be from 53714 -Jon
