PDP-11/93 memory question

by Bill Gunshannon

I have an 11/93 with 2MB of memory onboard. I would like to kick it up to 4MB. I got some memory a while ago that was supposed to be PMI for it but it turned out to be UNIBUS and thus no help. I have some old fashioned QBUS memory module floating around. Will these work to add the missing 2MB or can the 11/93 only use PMI? Would be nice to wake this old box up again. I have this cool Decromancer just crying for somewhere to run. bill

Endeco Cartridge Reader

by Steve Lewis

Is anyone familiar with the Type 1138SSM Cartridge Reader by Endeco, Inc (of Marion, MA) ? I recently got one, it appears to have an RS-232 interface at the back (and a power cable). I believe it is from around 1989. The cartridge slot has a connector that looks like something an NES might have. That is, it is not a tape, but it is much larger than CompactFlash. If anyone is familiar with these, I'm trying to find some cartridges and any kind of manual on how to interface with the thing. Thanks! Steve

Selling a Wang calculator

by pontus

Hi I know this isn't exactly the right group for this. But I have a fairly uncommon Wang calculator for sale and am not sure where to post about it. I've tried "Vintage Calculators Buy & Sell" on facebook without much luck. I see there is some calculator activity on discord, so I'll post about it there but I'd be happy for suggestion of other venues before I go the E-bay route. Below is the blurb I posted on facebook and here is a link to photos of the thing: https://drive.google.com/drive/folders/1gNdVSsNDxDL1Ukjh13-2ElJXRiWKQ5rx?us… FOR SALE: a Wang 362E electronic calculator in good condition, some scuff marks and light scratches but the inside is clean and looks to be complete. It comes with the 370K programming keyboard with nixie tube display in original dust cover, two card readers model 371 (with feet), four manuals in English and one in Swedish with handwritten notes. Also included is an IBM port-a-punch in box. I have decided not to test it in order to avoid causing any damage from improper handling or due to problems with ageing hardware. Located in Uppsala, Sweden. I will ship internationally but please allow some time for me to package it properly and figure out the best shipping options. I have shipped heavy computers and even CRTs with success, so I’m not without experience. Give me an offer :)

9-Track Tape Extraction

by lukeparkerson1＠gmail.com

Hi all, I recently got my hands on what I believe is a 9-track tape, dated 1986, which has some old survey data stored on it from a university research project several decades ago. I'm hoping to be able to extract the information from the tape and convert it to a more modern data file accessible to the public, but I don't know very much about these tapes nor do I have 9-track tape equipment. I'm wondering if anyone who is more familiar with this technology can tell me it's even still possible to extract this data, and if so, is there's anyone here who can try and run the tape, or knows someone with a working 9-track tape drive? The frame is not in the best shape, but the tape is hopefully fine. Here's a photo: https://drive.google.com/file/d/1PrdBnIWUO4-317ZSwqvY-TD6dHr2CxC8/view?usp=… Thanks, Luke
