Re: apollo psa test point adaptor
These are sturdy and notoriously expensive aerospace grade 38999 connectors. We had to slightly machine modern 38999’s male plugs to fit in these, but by in large it still fits the modern standard. I have one of the PSA trays it connects to, trying to make it work again! Nice and noble hardware it is.

Re: 11/93 Rebuild
Rod, others, I have so far been unsuccessful getting my CQD220A for SCSI HD, and RQDX3 for floppy to coexist in an 11/83, at least with bsd2.11. I am eager to hear whether you get both controllers working in the same box, and how. Mark Mark G.

11/93 Rebuild
Hi Guys Well the RD53 in my 11/93 finally clapped out. The CPU is a late model KDJ11-E with everything on the one board. So its a switch from MFM to SCSI Drives. A CQD220A will drive the hard disk and the RQDX3 will stay to look after the RX50 I've put the Hard Drive on the primary CSR address (17772150) and I will shift the RQDX3 to an alternate CSR Comments as to if this is the right way round and what CSR's to use for the two controllers invited.

H... Every VT100 I ever saw the inside of (not a lot, but a bunch) had the EMI coating on the inside. I always assumed it was to meet FCC spurious emissions requirements. Definitely not enough to meet TEMPEST requirements. bill

Exactly. After cruising for about a year or so, looking for tape seal replacements, I decided that none were to be had. Not even the few places that still sell NOS tapes had any to spare for any price. And any old stock is likely to be deteriorating. I suspect that no new tape seals have been produced in the last 20 years. After doing more investigation, I settled on 800' 16mm film cans made for archival preservation. There appear to be two types (I have samples of both)--one vented and the other not. This makes sense as a lot of acetate-based film stock was manufactured and, as it decays, gives off acetic acid, which, unless removed, further corrupts the film base. Of course, if you have the old Wright-Line style of tape racks, you can't hang film cans. Fortunately, all of the magnetic tape that I've seen is mylar-based, which doesn't have the problem, so no venting is necessary. Magtape issues are mostly due to deterioration of the tape binder, for which "baking" can go a long way to at least temporarily remedy. Both types of film cans are made from polypropylene, as far as I can tell, so they're probably good for my lifetime, at least. A 10.5" reel of tape fits quite nicely, such that no additional support is needed. Larry Urbanski seems to have the best price on the cans, about $5.75 each, but he'll negotiate for quantity. There may be better solutions, but I haven't come up with one yet. It's a bit funny; I can remember when the tape seal adoption was causing dumpster-loads of hard plastic tape cases to be scrapped. The cases that remain tend to be intact, even after 50 years. --Chuck

FWIW, IBM auto-load hard plastic seems to be holding up better, you might be able to find a small quantity of those around. Failing that, late era crappy tape might be found, and the seals scavenged though the price is probably prohibative.

Tape seals?
Just a reminder: "Tape seal" is a generic name (or defunct trademark?) for the wrap-around plastic tape hanger for half-inch magtape reels. There's a flexible white (soft plastic) or beige (hard plastic) belt with a clamp (sometimes black) and a hanger. They usually had a little place to put a label in them too. They usually came with a new reel of tape but you could also buy them by themselves. 20 years ago I had thousands of 9-tracks hanging from decaying tape seals. Every couple days I would find a couple of tapes dropped to the floor and their tape seal broken. At the time it was no problem to find surplus tapes with recent tape seals to rehang them, and tape seals were still available new. Most of mine came from Southern California where I think the ozone in the atmosphere severely limited useful life of the plastics. Here in 2019 I only have a few dozen tapes and few remaining tape seals. I suspect any source I found of tape seals would be selling 20-year old tape seals. Is there any outfit that sells "new tape seals"? Or a preferred better way to hang tapes in 2019? It wouldn't surprise me if an archivist told me hanging tapes was the wrong way to store them but I never have really noticed (temperature/humidity changes seem to be a way bigger problem than storage orientation). P.S. Yes all these tapes were imaged decades ago. Not really sure why I still have them around unless say I need to boot a PDP-11 or VAX OS from 9-track which I guess hasn't happened in at least a decade for me. Tim N3QE

Re: Kaur Collection Inventory
> From: Ed Cross > I saw a mystery PDP-11 in the garage that I believe to be an 11/70. Yeah, I think so; someone has transplanted a few red/purple toggles into it (perhaps some of the original blues got broken), but it's a /70 front panel, which won't (without major kludging/surgery) work on any other model. Without pictures of the insides of the main pull-out bay, and any others (there should be at least one, for the main memory) it's impossible to say how complete a system it is; -11/70 CPU boards are easy to find, though. > please help identify what I took pictures of. A couple of things I hoticed quickly: 2349 shows a PR05 high-speed paper tape reader (like the PC05, but reader-only), and 2325 a CR11 card reader (a Documation unit re-badged by DEC). My impression from looking at it all is that it's a huge pile of stuff, and some is probably just junk that should go to the scrappers. Their process, with the lawyer, is probably too top-heavy for a lot of the smaller items (e.g. 2387 shows a partial PDP-11 front panel which might be of some interest - e.g. I'd buy it if it showed up on eBait). Perhaps some one/group who is local can take everything that's left, after the main items (e.g. the VAX 750 - those are rare, I'm sure someone will scoop that up) are picked out, as a cheap lot, and sort out the good bits and put them up on eBait, and scrap the crap. > I hope this is useful to folks. Yes, very; thanks very much for putting in the effort. Noel
