I was wondering if anyone has an Alenco 108TK am/fm radio kit and knows the specs of the coils in that kit. I'm tinkering about with replicating that kit as a small PCB to be put into a wooden cabinet. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

DOS Widgets

by dave09＠dunfield.com

Not many DOSheads left (I still have a DOS machine on my desk which I use daily), but perhaps someone will still benefit from this... FWIW - I've started to catalog and post some of the various widgets I've created for DOS over the years. Items range from trivial utilities to fairly complex packages. Some of these were commercial packages that I once sold mail-order (and later the web), while others are just things I put together for my own use. I'm not sure if/where I'll post it permanantly, however for now I've put a link at the bottom of "Dave's old computers" - Enjoy.

Poly8813 on ebay

> The 8812 is not the original and much rarer Polymorphic Micro-Altair, > later called Poly-88. Those came out in 1976 and might fetch $8000. > The 8813 series were advertised into early 1979 and are worth more like > $400-600 at best, in unknown condition. > > Bill The 8812 is the same as the 8813 with the exception of it only having two disk drives. Re: the Micro-Altair. The story I've heard is that the Poly88 was originally named the Micro-Altair, but the name was changed because of objections from MITS. I've talked to a number of people who used to work at Polymorphic trying to find out if the Micro-Altair actually existed as a physical product. To date, I haven't found anyone who has said the Micro-Altair actually existed. FWIW as I've mentioned from time to time, I probably have the largest collection of Poly documentation left as well as stuff I've never heard of before. When Poly shut down, they put all of their stuff that was left in storage. A friend of mine knew the owner and acquired a lot of it, and gave it to me. One of my many todo projects is to get this stuff saved as it includes source code and manuals for most of their products. There is a little over one full filing cabinet full of docs in addition to several boxes of parts. Something that I find fascinating is one of their business plans after Poly had a change in management about 1981 as it includes flyers and information about their then current product line.

Looking for StorageTek 2500 series 9T tape drive parts.

by rollerton＠gmail.com

I have 4 Storage Tek 2500 series drives on my Sigma 9 that we are working on and hope to get two of them into service. I need to find replacement belts that drive the two air pumps. They are narrow modern looking things maybe 1/4" wide and shaped like a space age vbelt, I don't have the parts books with me, but my question is more a general one; Any one know of a source for spare parts for old Storagetek drives? Thanks. Oh, and any of you Sigma folks out there, contact me off the list if you like. Bob.

New PDP 11/34

by stephane.tsacas＠gmail.com

Hi, A PDP11/34 has just arrived... I need some basic help before I'll power it on. The description of the current setup can be seen there : http://www.conservatique.com/pdp/pdp-1134?. 1- There is 2 wires cable coming out the front panel, pins TB1/TB2, which goes to the rear of the box, towards the power supply. From the schematics Fig 9-5 (p64): http://docs.google.com/viewer?url=http://www.mirrorservice.org/sites/www.bi… this cable should go to a M9301 ? What if I don't have a M9301? Is there a M9301 Boostrap/Terminator Maintenance Manual available somewhere by any chance? 2- How can I test the power supply? I don't see any voltage control points, I couldn't find how I can?access?to the boards under the transformer. If anyone has the following boards for sale/trade, please drop me a mail: - a M9301 ! - any memory which can fit (MOS or CORE). I have some 11/70 core modules for trade I think ;-) Thanks! -- Stephane http://DECpicted.blogspot.com

Looking for TRS-80 Model I Keyboard unit...

by alhartman＠yahoo.com

During my recent move, my Model I took a tumble and has a broken case and keyboard. I'm not even going to try to power it on until we can look it over carefully. I'm looking for a donor unit that can contribute a bottom case and keyboard with keypad. The logic board does not have to be working, and no power supply is needed. If someone has such a unit, or can point me to someone I can buy a new keyboard from, I'd be most appreciative. Al Hartman Keansburg, NJ
