DEC Boot PROMs; Looking for Old PROM Programmer

by mcquiggi＠sfu.ca

Hi All: I have been lurking for several years, although I was quite active in the retrocomputing community before that. Work and other pleasures kept me a bit inactive until my retirement last summer. Just coming up for air! I have several old DEC systems, including pdp-8s, pdp-11s, and VAXen. I am getting going on them again. I have acquired some new (NOS I suppose) 82S131 ROM chips, and am looking to write some boot ROMs for my 11/34. Specifically, these are chips that fit into an M9312 Unibus terminator/boot ROM card. I want to create RX01 and RX02 boot ROMs. In DEC-speak, these are 753A9 and 811A9 part numbers. The ROM images are available through Don North at (http://www.ak6dn.dyndns.org/PDP-11/M9312/). Thanks Don! I have a one-size-fits-all new-fangled EPROM/PROM programmer, and I thought I had it made when I saw the chips. Unfortunately, my programmer is too new to handle these chips. Sigh! I wonder if anyone has a programmer they will either part with; or who I could send the 82S131 ROM blanks to, for programming. Alternatively, if anyone has spares of the these chips (753A9 and 811A9), I can swap you blanks for them. Thanks and I am looking forward to becoming active on the list and in the hobby/fixation again! Kevin mcquiggi at sfu.ca

Ohio Scientific Challenger 1P

by jon＠jonworld.com

All, I've come across one of these systems. Is there any interest in these? There are 3 RCA jacks on the back, but they aren't labelled. I know that 2 are for a tape recorder and one is video, but which is which? Anyone know off-hand? I'd like to verify if it works/runs OK. It belongs to a friend of mine and he needs to get as much cash out of it as possible. Any ideas/offers are welcome. Thanks! -- -Jon Jonathan Katz, Indianapolis, IN.

Does anyone have any use for UltraSCSI hard disks?

by lproven＠gmail.com

Not sure if SCSI-3 is too modern. I have some plain ol' SCSI2 ones going up soon, too. Anyway, I have just listed a couple of ST19171W drives on the Bay of E: items 270900073846 & 270900074301, I believe. Please excuse the pimping - just thought someone might be interested. Opening price, 99p. (A buck fifty, roughly.) -- Liam Proven ? Profile: http://lproven.livejournal.com/profile Email: lproven at cix.co.uk ?

DEC terminals for New England Digital Synclavier II

by tshoppa＠wmata.com

> The genuine VT100 has a white phosphor IIRC, but the VT640 I > say had a green phosphor CRT fitted. All the DEC CRT terminals were available with customers choice of green, white, or amber CRT's. Probably some other phosphors I didn't see too. The default phosphor was white for the VT100. My distant memory tells me that VT100-LC was the order code for the green phosphor I liked best (P31, long glow?). By the time of the VT-220, amber was really popular. Tim.

Seattle Retro-Computing Society's 1st 2012 meeting: Sat. Jan. 28th

by searetcompsoc＠gmail.com

Come one, come all, to the Seattle Retro-Computing Society's first monthly meeting of 2012! It will be held Saturday, January 28th from 11:30 AM to 5:00 PM (please note our new, later starting time). Do you do any of the following with old computers? Will you be near Seattle on Saturday? + Use, collect, and/or restore them + Play games on them + Write programs for them + Develop new hardware for them + Help other people do any of the above If your answer was "yes," then the SRCS is for you! We exist so you can show off your awesome stuff, bounce ideas off of fellow enthusiasts, and be inspired by one another's achievements, plans and aspirations. No idea is too big or too small, and we're not picky about what flavor of vintage machine you prefer! Come on down and tell us about it! The meetings are graciously hosted by the Living Computer Museum, which is gradually fitting out a computer museum in Seattle's SODO neighborhood. There will be refreshments, a Buy-Sell-Free-Trade table, and enough table space & power to set up anything you may want to show off! For further details, please see our web page at http://www.seattleretrocomputing.com/ and our mailing list at http://groups.google.com/group/seattle-retrocomp . Hope to see you there!

Availability of 36-bit systems [was RE: new haul, serious goodies]

You can always play on our Tops-10 and TOPS-20 systems, which are assuredly very real hardware.

Here is a link to the manual http://vintagecomputer.net/OSI/Challenger_1P/C1P-UserManual.pdf Here is a link to my hacked up OSI 1P just to make the point that no two are going to be alike, the video could be different than the users guide. http://vintagecomputer.net/OSI/Challenger_1P/ Note - the 1P is the same thing as a Superboard II with a chassis/cover.
