In the time-wasting sense: The Integer Basic games that came on cassette and had an Apple I heritage, ESPECIALLY Apple Trek but to a lesser extent Breakout and Pong too Beagle Bag, or Applesoft Basic and any Beagle Bros catalog, or just a Peeks and Pokes chart. Lemonade Sabotage None are killer apps But all are excellent fun Tim.

Mouse and Keyboard Cable for DECstation 5000/240

by robert.jarratt＠ntlworld.com

I am looking for the special cable that connects mouse and keyboard to a DECstation 5000-240. Unfortunately I don't even know a part number. Can anyone tell me what part number to look for? Better still, anyone have one going spare? Regards Rob

Almost free: various DEC, HP, Fluke, Wyse items, for pickup Rockville, MD, USA

by js＠cimmeri.com

Items located in Rockville, MD, 20850. Almost free: $2 (two) dollars per item, local pickup only at this time, no photos. Special offer intended especially for anyone having a hard time due to economy. I'm needing to make space fast and clear out items without hassle of ebay, ads, photos, etc.. 1.California Computer Systems S-100 chassis, with 12-slot passive terminated backplane, power supply, fan, filter. The chassis functions perfectly, has been thoroughly cleaned, and the PSU caps have been reformed. Cosmetically, the chassis is decent: has dings, scratches, some minor bends in sheet metal. 2. Fluke 8520A/AS-1 rackmount digital multimeter with GPIB. Perfect cosmetic and functional condition. 3. Digital BA23 floor pedestal enclosure, complete with front + rear covers. Very decent shape. No yellowing (painted). 4. Digital LA100 Letterprinter w/ ribbons. Tested working. Mild yellowing of plastic but not disagreeable. 5. Digital LA75 Plus Companion Printer (LA75S-A2) w/ parallel + MMJ. Professionally refurbished and assumed working (but untested). Clean and nice cosmetic shape. No yellowing. 6. Wyse 60 terminal with keyboard and spare analog board. Terminal unit is in excellent shape all around, as is spare analog board. Keyboard works but 3 of the keycaps broke when it slid off my desk. No yellowing. 7. HP PA-RISC Model 712/60 computer with floppy, hard drive, new keyboard and new mouse. Currently loaded with the NEXT operating system. I have the original hard disk with HPUX on it. You can have one OR the other. Computer is in perfect cosmetic and working condition. My handle on ebay is MdntTrain if anyone wishes to verify my character and reputation. Email me if interested in any or all. I will select who the items go to. Thank you, John Singleton js at cimmeri.com

Tektronix inkjet printer (ancient stuff)

by mark.kahrs＠gmail.com

I had this idea once and so I gutted a Tektronix inkjet printer --- what I have is a set of driver boards and the inkjets. This is part number 070-8072-00 and others. If you'd like them, all I ask is that you pay postage / shipping.

Sighted on CL: Sun SparcStations FS (Oregon)

by cclist＠sydex.com

Don't know if this interests anyone, but I spotted this in the local Craigslist: http://eugene.craigslist.org/sys/1963898368.html On the same day's postings, I note that the UofO is surplusing an LSI ADM-31 terminal for $50. --Chuck

And then, of course, you need a font. > I haven't seen a VT525 in the wild, but now I know what to do to show > it off if I do get one (but now I'm also wondering what it would take > to get what you have working on a Tektronix 4105 since I have a couple > of those). I don't think you want to go down that path. :-) I did say "primitive" graphics. Beyond Zork uses font 3 to play with some crude graphics. Basically mapping, and some bar charts and nice framing. And, of course, it uses color if possible. But if you are interested, I can send you my Z-machine font definitions for the VT200, VT200, VT400 and VT500 terminals, so you don't have to define those yourself. As for playing, if you just have a VT525, it's easy to test, by just logging in to Mim.Update.UU.SE, and play any Infocom game on that machine. My Z-machine for the PDP-11 do handle the font and color stuff for the VT terminals (of course). :-) Johnny

Sorry, I've been out of town some, and have not had time to make comments for a while. As for the previous stuff on modem signals and so on, I was caught in a small lie, yes. Properly, it isn't right to hook to DTEs together with a crossed cable. But I'm willing to cheat on that one. I'll let the rest of the RS-232 stuff rest unless we really want to revive that thread... As for the VT525, yes, it is correct that it's just a base unit with no screen or keyboard. It has a normal VGA connector for any VGA screen on the back, along with two MMJ connectors and two DB-25 connectors (unless my memory fails me). As for colors, well... The VT241 and VT340 have no way at all to select colors for text. You can, however, select that different attributes, such as bold and so on, instead be rendered in other colors. And the VT525 can do that as well. So it is as compatible with the older terminals as much as is possible. But, people might say, I have seen output in different colors on the VT340... Yes, you can do output in all colors on those older terminals. The problem is, you need to switch to REGIS to do that. Ie, you do that when playing around in graphic mode, which the VT525 don't have, so there is no way it could do this in a way that would be compatible with the older color VT terminals, with less than implementing the full REGIS stuff. So, in the end, implementing the ANSI color codes was the only reasonable way to get colored output on the VT525, and it is nice to have... I like playing Beyond Zork with color and primitive graphics on my PDP11... :-) Johnny

VCFMW5.0: Success!

by silent700＠gmail.com

Old computers. A running network. Friends. Dinner. Community. New innovations in old gear. Aching backs. A lot of laughs. A little bit of capacitor smoke in the air. Alas, another VCF has passed - but what a time it was! While the seeds of plans for next year sprout, our first priority is to collect documents of this event. If you took pictures or video and have them hosted somewhere, and would like them up on the vcfmw page, please send me a link and I'll post it ASAP. You'll find them here: http://vcfmw.org I feel I can speak on behalf of the other vcfmw organizers and the Chicago-area retrocomputing community at large when I issue a big THANK YOU to all who attended, whether it was from our own backyard or >from out across the plains. You are what made the show work - without your enthusiasm, knowledge and spirit we'd have been a lonely bunch in the basement. There are a few shirts remaining, if anyone wants one for posterity. I will count them up and post a list soon. I do know we're sold out of "XL" and have a number of "L" left, along with a few M and XXL. There are mostly black ones with a few blue (which proved more popular than expected.) The front design is here (the back is just the URL:) http://picasaweb.google.com/Silent700/VCFMW50OfficialGraphics#5512512730455… Again, thanks to all who attended, helped out and made it an awesome night. It's events like this that keep the hobby alive and strong. -j --
