This can be fixed by adding a "noredirect=1" argument to the URL but placement matters:
This concludes our lesson.

I was hoping there was a complete guide out there for IBM elements but I haven't found it (sounds like another project.) I did find some scans of a brochure from GP, who also made elements for the Selectric line. I compiled them into a PDF for the docs site.

Today's upgrade is the home-made equipment rack. My first project involving my new table saw. No fingers were lost in this operation:
From the bottom:
- Micronta DVM
- Tektronix 466 'scope
- A pair of low-amperage, noisy PSUs (will be replacing as soon as I can pick out a decent one)
- China-brand frequency detector
- Micro-Seven PBX emulator
And in the front is a Heathkit analog/digital lab/trainer.

However, most of the articles that have popped up in searches have been from the early 80s - prime time for oddball hardware and non-standard systems. So where are those issues? Well, let's tweak that URL:
Looks like they now start at 12/11/78 - big difference!
They're still indexed by Google yet are not browseable. Intentional or just a bug in their catalog? I dunno.

What can I store safely out in the garage? It will be subject to some great temperature swings (it probably doesn't get more than a couple degrees off the house heat) but it's mainly dry. I've had terminals, desktops, routers, etc out there for couple years with no visible damage. I guess the easy answer is "the cheap stuff." So I'll be moving the SOL-20, etc inside...
Pictures when it's all done? Sure. But it will never be done!

The build quality is definitely a step behind the 8M. The plastic is odd: flexible yet brittle and with a weird texture (which I tried to show in the pics.) The system ROMs are real Soviet chips, which I did not find in the 8M (I have yet to photograph that one in detail.) The PSU is downright scary and the input current is not switchable. The 8M's PSU appears to be a clone of the ones Apple used. This one is definitely home-grown. I have a voltage converter from Fry's which should do the job.
At VCF I used Apple-branded drives and an Apple Disk ][ controller in the 8M. This time I have real Bulgarian disk controllers (he was kind enough to send two this time to make up for the lack of one last time) and floppy drives. The drives don't seem to have been made under the Pravetz label. Instead they are marked with the "Kocho Tsvetarov" name, which appears to be some sort of electronics factory.
Here's a whole gallery of pics I took last night. And here's an interesting document: a US Gov (financed, at least) report on Eastern Bloc tech circa 1984. I found it when googling the name on the back of the floppy drives I got with the Pravetz 82. I OCR'd it and rehosted it in case it goes away.

Next is getting that rear cable manager and side panels on.

I bent the panel mounts getting the rack in and out of the truck but I've got them more-or-less straight now. I put a side panel on and she's looking pretty sweet. The major job that needs doing now is addressing the rust on the bottom third of the front panel. A trip to Home Depot is in my future, and a purchase of harsh steel-wool and some Rust-o-leum primer. Then I have to figure out how to match that distinctive DEC beige so I can re-paint the panel. I'd settle for a near-match if it weren't for the painted logo on the panel - if I fail to mask that perfectly (and I will,) I'll have a section of original paint around it that will be an obvious mismatch to the repainted sections.
Quite a bit of work for something I'll likely end up giving away, or worse :(

Meanwhile, VCF-MW was a blast. I learned a few things about organizing a show and just how much stuff I can't do at the same time. I gained a lot of ideas about how to fine-tune things for next year. I've been collecting attendees' photo galleries on the main page:
There's some really great stuff there. Check them all out.

Unlike the Vonage box I got a few months ago and tried fruitlessly to open up, I actually found a procedure that worked for this device. Here it is for future reference:

Closest thing we have in the Midwest to a Weird Stuff.
** UPDATE **
IBM Model M "Industrial" version (grey color)
SQ312RD drive/SQ200 cartridge - an MFM Syquest drive? Yes!
5.25" Bernoulli drive (SCSI)
50' (?) DEC AUI network cable and a smaller one
A bunch of 8" floppy disks, some 3M and some individually packaged pre-formatted ones.
Some odd IBM serial cables with huge molded connectors
Ameritech Cellular sales tape (Wisconsin market)
3x IBM CGA video cards
Some kind of ISA Twinax card (terminal emulator for System/36? network?)
Not a bad haul and better than most hamfests I've been to in the last five years. Of course, none of their stock will be replenished any time soon, so it's kind of a one-time deal.
