I have the following on eBay, ending this weekend VT330 Item # 330613186993 LK250 keyboards: # 330607337643, 330607337630 Hmmm... have to go fix the photos. I am cleaning the basement, I will have a bunch of DEC ephemera and random databooks from the late 1970s, for the cost of shipping. Will list a link some time when I can put together a list. Dave.

ASR 33 For Sale - Fully Restored

by billdeg＠degnanco.com

(I am passing this along for a friend who restores and sells teletypes) "..It has been serviced, tested in local and line mode and is in excellent operating condition. Only the motor gears, belt, oil pad and rubber hammer were replaced to bring it up to like new operating condition. It has an even parity keyboard. This is the nicest 33 I have seen in many years. The only thing that keeps it from being perfect is a few minor nicks on the cover and some scratches on the pedestal. No copyholder is included, but a source for them is available if one is desired. This 33 has a rare lighted lid w/window Teletype option. If this option is not desired, the lid will be replaced with another very nice one. .." Pictures: http://vintagecomputer.net/wayne/Description_and_pics_of_Sept_2001_33.pdf $1200 Please email teletypeparts-at-aol.com if you have any questions.

DEC Floppy drive DS-53A

by cclist＠sydex.com

Does anyone have the specs for the JPN DS-53A half-height 5.25" floppy drive? Apparently it was used on some Digital equipment, as units with DEC branding exist. The web is conflicted--either it's a 360K or a 1.2M drive. I'm wondering if it's just an RX50 clone in a half-height package and SS 96 tpi double-density. Does anyone know for certain? Thanks, Chuck

Also there is no DOS card included. I am of course biased, I got my system for free. Bill

cleaning and maintenance for an ASR33

by starbase89＠gmail.com

Hello. I have an ASR 33 teletype that I am trying to clean up and make it run well. It does work. I plan to have it hooked up to a PC via a current loop to RS232 adapter and have HeavyMetal feeding it text. It is very dirty. I replaced the ribbon. Basically, here's what I'd like to know: What parts need to be cleaned and/or lubricated? How do I clean out the paper tape punch scrap container? Can I use compressed air to remove dust, or would that cause damage? Thanks much Joe

Interesting email addresses of old...

by tshoppa＠wmata.com

For my first 4 years with E-mail I was only on DECNET/HEPNET. So DECNET style E-mail addresses for me (TDS222 at IOWA and TSHOPPA at FNALF). Later on, some of my BITNET E-mail addresses from the 80's and early 90's are found when I google myself. Some of these were on the same VAXes via BITNET gateways, others were on PRIMOS machines on BITNET, a couple were genuinely on IBM hardware and then later Amdahl hardware. I really struggled with the IBM user interfaces :-). I did use UUCP forwarding on several occasions but I never thought of the bang-path as "my E-mail address". Amazingly enough several of the LISTSERV's that I subscribed to/posted to back in the 80's still exist today in one form or another. Some were surprisingly hard to find but they're still there.

It may not be a disaster but sometimes it is very hard to solder the new IC on the component side. /Jonas

Seattle Retro-Computing Society's monthly meeting Saturday, September 17th, 2011

by glen.slick＠gmail.com

[forwarded on behalf of SRCS] Come one, come all, to the Seattle Retro-Computing Society's monthly meeting, on Saturday, September 17th, 2011! Do you do any of the following with old computers near Seattle? + 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," as I expect it will be if you're reading this near Seattle, 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, a relatively new organization which is building 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 newly improved web page at http://www.seattleretrocomputing.com/ and our mailing list at http://groups.google.com/group/seattle-retrocomp . Hope to see you there! (Please note, we usually meet on the fourth Saturday of each month; we had to move it up a week this month because of schedule conflicts with retrocomputing events in other cities.) Gordon "gsteemso" Steemson SRCS agitator-in-chief
