I am looking for a supply of 307.2 kHz crystals to restore some TV Typewriters. I need 2 crystals and someone else needs one or two. I have not been able to locate any. I can get them made at International Crystal Manufacturing (ICM) for about $55 each with a 6 week lead time. http://www.icmfg.com/crystal_hc51u.html I would like to find some at a better price. I can make a small PCB with a 1.8432 MHz oscillator and a divide by 6 IC. This would cost about $75 total for 6 items, but I would like to find a crystal. I am adding the baud rate option to the CT-S serial interface, the default was a fixed 110 baud. http://www.swtpc.com/mholley/CT_1024/CT1024_Index.htm Michael Holley www.swtpc.com/mholley

Original IBM PC, Apple Macintosh cube, interest?

by gunther＠aurora.regenstrief.org

Well, I had at least 4 people asking me individually what the Max cubes go for these days. And I do not know the answer. I could dig them out somewhere (that is, last week I could, now it may be too late ... but I might find one again.) Interesting, noone wanted the original IBM PC, even though it probably has a "Color Graphics Adapter" (woa! with 40 characters per line!) and the Mac was just B/W right? So, what would people pay for a Mac or an original PC? -Gunther

hp terminal pictures?

by jwest＠classiccmp.org

I'm looking for a particular HP terminal. Don't know the model, but I know what it looks like. I know it is a 2600 series terminal, something like a 2621, 2622, 2623, 2624, 2627, 2640, 2644, 2645... but not sure which one. I'm not having any luck googling for pictures of HP terminals so I can find the one I'm looking for. Anyone know where there's pics? Jay West

PDT 11/150

by bmachacek＠pcisys.net

Hi All: I just rescued a Digital PDT 11/150 from going to the scarp yard. Now that I have it, what have I got? I also got a number of 8" disks and a VT100. Both units are very heavy units. I am not a DEC person, but I figured these were pretty old units and I just couldn't stand the thought of them going to the trash heap. Thanks Bill Machacek

Looking for DEC DLV11J cab kits

by waltje＠pdp11.nl

Hiyas, Looking for the cab kits for the DLV11J (4-port serial) cards, so I can set up a small LSI-11 based system. I already have a small Q/Q backplane (thx, Luc !) and will hook up a nice, small switching PSU to it... together with a cabkit and general CPU cabkit panel, this will make a nice "this is a small PDP-11 system" demo. (especially if I can find the guy who did the Qbus IDE disk driver card, as I have plenty 2G 2.5" IDE notebook disks to glue to such cards :) Cheers, Fred -- Fred N. van Kempen, DEC (Digital Equipment Corporation) Collector/Archivist Visit the VAXlab Project at http://www.pdp11.nl/VAXlab/ Visit the Archives at http://www.pdp11.nl/ Email: waltje(a)pdp11.nl BUSSUM, THE NETHERLANDS / Sunnyvale, CA, USA

Configuring a CMD CQD-220/TM

by pat＠purdueriots.com

I've got a CMD CQD-220/TM that I'm trying to get set up. I've placed it into a VAXstation 3200, and it shows up when I do a 'show qbus' and 'show dev' at the SRM prompt. At some point I was able to find a list of jumper settings on the board, and instructions to access the config menus on the board via the SRM console, but alas, no more. Does anyone have configuration info for this board? -- Purdue University ITAP/RCS Information Technology at Purdue Research Computing and Storage http://www.itap.purdue.edu/rcs/
