WTT: J&M Systems TRS-80 5.25" Alignment Package
by Jonathan Chapman 23 May '22

23 May '22

All, I recently did some drive alignment work for a customer and ended up doing a trade for some alignment diskettes. One set is a J&M Systems, LTD. package with a Dysan 508-200 "Diagnostic" diskette, and a "DISK DRIVE ANALYZER DDA V3.3" program diskette. I stuck the Dysan diskette in a drive that had just been aligned and "explored" it a little with the oscilloscope. It's not a usual Dysan alignment diskette and does not appear to have the radial alignment patterns on it. Since I don't have any TRS-80 gear, it's not a ton of use to me. If anyone is interested, I'd like to trade for another alignment diskette in some other format I can use. Let me know what you've got! Thanks, Jonathan

Looking for an SCA adapter
by Jason Perkins 23 May '22

23 May '22

All, I'm looking for an 80 pin SCA to 50 pin SCSI adapter.... with 16 bit termination. All the ones I can find now either don't have termination, or only have 8 bit termination. Vendors that have them listed on their sites respond that they're NLA when emailed. I have some late SCA drives, and want to use one on in a Mac SE/30. They don't seem to have any built in termination, and get upset if only half of the lines are terminated! If you have one or two of these you'd like to part with shoot me a note!

Re: [vcf-midatlantic] OT: time to downsize
by Bob Shuster 22 May '22

22 May '22

Another update - TI stuff posted! Tomorrow I’ll figure out which system to pull out next. New pages posted at: theshusters.com/bobvintage.html <http://theshusters.com/bobvintage.html> - check it out. Please read through the first page and that will answer many questions. If you're reading this list you have my email - it's intentionally not listed on the pages. And again, I'm only making this stuff available to those on this listserv for now. Once I finish going through everything (and there's still a lot more) and I've given list members time to peruse, I'll start listing elsewhere, but mainly I'd like to see the stuff go somewhere where it will be appreciated! Thanks for looking! - Bob Shuster

FS: Early National Instruments DM8200D Comparator
by Jonathan Chapman 21 May '22

21 May '22

All, Finally listed the National Semiconductor DM8200D that Evil Mad Scientist Labs did some super macro photography of: https://www.ebay.com/itm/275320526785 An unremarkable part for its function (it's a 4-bit magnitude comparator, it does work!), but the packaging is interesting. It's in a "ceramic sandwich" DIP, which is a piece of ceramic with a hole for the die and the leadframe in it, sandwiched between two pieces of gold-plated metal. That's uncommon enough as it is, but additionally, the pins are actually rolled instead of being stamped! Pictures explain better than words, here's an imgur album with higher resolution pictures: https://imgur.com/a/TCrIxEH Anyway, I figured I'd post here more because people might not have seen the original EMSL picture thread elsewhere. It's listed for $1 starting bid, no idea what it's worth :P Thanks, Jonathan

Here is his post: " Hi everyone - I wrote another new PET game at a recent game jam for anyone interested - I called it TrekWar! It's kind of a combo of the Star Trek text games (you have multiple quadrants to go do things like gather dilithium and shoot Klingons) + Asteroids (top down view of your ship) + Defender (you fly around a moving map). Works on 3032, 4032 and 8032.

Simple Commodore drive question
by Kelly Leavitt 18 May '22

Is there anything special about the serial disk drive cable for the 1541s or will any straight through 6 pin DIN work? I have several drives but I don't seem to have any of the cables. Thanks, Kelly
