Hi folks, The PSU for my Executel 8085 system is an Astec AC8151-01 40W 5A unit that puts out +5/+12/-12V. A while back somone suggested using an ATX PSU in its place which TBH I'd forgotten about untl I saw a breakout board that you plug a 20 or 24 pin ATX supply into and it terminates each rail in whatever you choose to solder in. ukp8, rude not to :) My only worry is an ATX PSU is capable of putting out a lot more than 5A if it goes wrong so I'd like to protect each rail with an appropriate fuse. Any downsides to resettable polyfuses? Cheers, -- adrian/witchy Owner of Binary Dinosaurs, the UK's biggest home computer collection? www.binarydinosaurs.co.uk

by akb+lists.cctalk＠mirror.to

I have about four or five hundred things I'm ready to stop owning. I'm in Boston. If anyone wants a number of objects, I could deliver to VCF East this weekend. Inventory list at: http://threefingered.com/2017_inventory_3.html I have someone interested in getting all of the TK-50s, OSF/1 and Digital Unix CDs, and some of the VME boards, so those things might not be available. Contact me at decruft @ mirror.to please. Items I'd especially like to find good homes for are the DECNIS cables and the Adak ISDN box, anyone interested in those items is welcome to them for cost of postage and a good story about why you want it.

Acclaim Entertainment Indy (with data, emails, etc) on eBay

by mj＠mjturner.net

Hi, I came across this on eBay today: www.ebay.com/itm/162446083760 To quote from the listing: Own a piece of gaming history! This Indy workstation was once owned by Acclaim Entertainment, the legendary game publisher, and was liquidated at Acclaim's bankruptcy sale in 2004. It sat untouched in a Brooklyn warehouse for more than a decade before being recovered last year. This Indy, "pup," was used for internal Acclaim business operations at its headquarters in Glen Cove, NY. It features user account information and internal company files for a number of Acclaim employees: Andy Skalka: More than a hundred e-mail messages about Acclaim IT operations (see photos) Danielle Papsidero: More than five hundred e-mail messages (see photos) Rob Zimmelman: Image sequence for Dragonheart game combat EVa motion capture editing software (unlicensed) BioMotion motion capture editing software (unlicensed) Motion captured animation data (Dreamworks, baseball, Batman, etc.) Licenses: various expired and/or inactive licenses for Nichimen N-World and BioMotionEditor No affiliation with the seller, but it sounds like an interesting piece of history. Price is $199 BIN. Cheers, MJ -- Michael-John Turner * mj at mjturner.net * http://mjturner.net/

PDP-11/20 in Iowa (x3)

by jnc＠mercury.lcs.mit.edu

> From: Philipp Hachtmann > The 11/20 is the simplest 11 as far as I know. 'Simplest' in what sense? They certainly aren't the easiest ones to understand, with all that random control logic! The -11/04 is far easier to understand (for me, at least; YMMV). > From: Ethan Dicks > Was there ever a quad MOS memory board for the 11/20? I'm pretty sure there was never a UNIBUS quad memory card from DEC. > if anyone knows where to get a crate of 110V Boxer fans for around > $5/each, let me know New ones (not exactly the same as the originals, but the right size in the X/Y directions, if not identical in the Z, and 110V, with the same kind of power connector) are available on eBait for around $10 each. Look for "120mm 110V fan". Noel

Introducing the UUCP/Usenet Project

by wkt＠tuhs.org

Hi all, as part of the upcoming 50th anniversary of Unix in mid-2019, a bunch of people are working to rebuild the mid-1980s uucp/Usenet network using (real/simulated) period-accurate systems. To make things easier, we are simulating the dialup lines too. Details of the (nearly) turnkey software to do this is at: https://github.com/DoctorWkt/4bsd-uucp A map of what nodes we have so far is at: https://raw.githubusercontent.com/DoctorWkt/4bsd-uucp/4.3BSD/uucp.png If you are interested in participating, email me back. Cheers, Warren

Not Getting Emails

by robert.jarratt＠ntlworld.com

I have not had any emails from cctalk for 2 or 3 weeks. I went to my subscription details and saw that emails were disabled for me. I re-enabled them a few days ago but I still have not received any new emails. I can see that there is traffic by looking at the archives, and if I am not getting emails I hope to at least see this one appear in the archive and hopefully read replies there too. Is it just me? Regards Rob

Microdata and Decision Data haul from usual site

by jwsmail＠jwsss.com

I was able to get hold of a lot of boards which had been pulled from two Decision Data's and a Western Dynex 2400 RPM 10mb (probably) drive. The Dynex drive is similar to the RL02 and in fact was configurable to look like one in one of the options. Microdata would have used 24 sector packs vs. the 12 sector packs used by DEC, however. One of the CPUs is a pretty ordinary Data / Control set made by Microdata but with most of the etch and silkscreen modified to have Decision data info. I'm going to check with my Microdata people and see if anyone recalls if this was done by Microdata, or by DD themselves. There is a nice find however, a 2901 CPU 16 bit system cpu set and memory. It also runs in the 130 pin Microdata 1600 backplane, which makes it interesting. I'd love to get information and drawings as much as might be around for this set. May be donating most of it to add to my 1600 system @ the CHM, as there are boards here which I didn't have examples of to donate at the time. Will check with them after I fondle the boards for a while. It's cool to have an additional example of a possible Microdata 1600 type CPU, as this is one of my collecting areas. I'll be adding in titles and comments on the photos later, but here are photos of the boards for now. http://jim-st.blogspot.com/2017/03/microdata-decision-data-and-western.html Thanks Jim

Unfortunately, we have not been able to update pricing and shipping costs on these sites. These manuals and parts were purchased when we had a large repair and calibration lab. Many are one of a kind and subject to prior sale. We have over 43000 different listings on www.etestmanuals.com <http://na02.mypinpointe.com/link.php?M=48182615&N=48220&L=22673&F=H>.

On our two websites listed above, we encourage you to make a list and contact us at jtucker at tucker.com <mailto:jtucker at tucker.com> regarding consolidated prices and shipping costs. Our websites can be used to look equipment up, but not to take advantage of the 50% discount prices this week. We can send you PayPal invoices for any purchases not done on eBay. In all cases you have the buyer protection of PayPal. We can also take Credit Cards. Our phone number is 2143488800. We do prefer email to jtucker at tucker.com <mailto:jtucker at tucker.com> as most questions about manuals require research and can?t be handled by a phone call.

STC 2920 tapedrive schematics

All the docs should be available on bitsavers by now, although I don't remember if it's under 'stc' or 'storagetek' or both.
