FS: More Ohio Scientific 495 Boards
by Systems Glitch 22 Apr '16

22 Apr '16

link: http://www.ebay.com/itm/272173918152 Buy it Now for $100, feel free to make an offer! $100 is slightly less than I have in each board. These are the three remaining spares from my prototype run. I'll use their sales to determine if/when I'm going to do another run -- don't want to get stuck with a ton of protoboards and be out the money. *** If you want one of these, let me know! *** I'd be happy to keep them as a stock item, but I don't think there's going to be huge demand for them. Thanks, Jonathan

FS: Applied Microsystems EM-188 Intel 8080 8085 Diagnostic Emulator
by Systems Glitch 07 Apr '16

07 Apr '16

link: http://www.ebay.com/itm/272125508235 ** NOTE: This unit is missing the emulator pods! ** Picked it up at either a hamfest or university surplus auction, I don't remember which. I've been searching for 8080 or 8085 pods for this unit for several years. I'm calling it a loss, so it's time to sell it. Perhaps someone has the pods and can make use of it. It does power on, and you can see from the pictures it has six TIL311 displays in it. I believe it also has a number of 6116 2K x 8 static RAMs inside -- I opened it up at one point in the past. This would've been an excellent tool for vintage computer debugging, if I could've found the pods. The emulator lets you observe and control the data and address bus states, as well as internal state of the CPU. If you're going to be at VCF East this year, I can drop it off in person and avoid shipping. That will of course be a *major* consideration if anyone wants to submit Best Offers :) Thanks, Jonathan

Then take I-95 north and pick up I-195 east to Rt-18. There NO TOLL on any of that route. It's, essentially, how I go to and from Philly and PHL, and Jackson. Why spent countless hours riding a train to nowhere and standing on sidings awaiting another? Trains are fine in the UK and .EU -- I have ridden them often when on the eastern side of the Atlantic swamp -- but there's just no comparable equivalent when here in the states. I-95 to I-195 is about as direct as one can get and it'll keep folks from getting lost on the roadways. The added benefit, no forced donation to Uncle Sam via tolls!

Rumor has it there will be some very exotic microcomputer stuff on display in our group's official booth during VCF East April 15-17. As in, early/mid-1970s uber-rare coveted stuff. Yes I am being cryptic. :)

May 14 -- New museum open house

I propose that we have > our next repair workshop coinciding with this event. It > would be very good of us InfoAge-citizen-wise if lots > of us show up that Saturday... You put this as a proposal, so it's a request for comments. I recommend against this proposal, to link a repair workshop with the grand opening event. The point of a repair workshop is to work, on repair. This Saturday event would eat up almost all of Saturday, in preparation and the event itself. But I may attend the grand opening, as you said that's supportive of InfoAge. You might consider some other specific VCFed museum activity that would coincide with and support the opening event. A demonstration of repair for instance - like straightforward repair of common vintage computers, that's something you'd not demonstrate during regular museum operation. As it's a month after the VCF-E re-opening of the museum, it's not reasonable to make a special exhibit. But it's possible there's some "crossover" items you could show, related to other InfoAge groups. For instance, radio amateur's early use of microcomputers for networking, repeaters, Morse code. I have some artifacts of that sort I could lend. Also you might make a poster showing "before" and "after" to make the point about VCFed use of the new building. So I've made positive counter-proposals, about your proposal to support the InfoAge open house. Herb Johnson -- Herbert R. Johnson, New Jersey USA http://www.retrotechnology.com OR .net

Thought - might not be good to have a formal workshop, but it does make sense that our club show up in force to help out, show our colors regardless of what we do, and if that means some make on the spot repairs in response to a specific issue that comes up, it's good that we come prepared just in case.

I remember it being a "bike allowed" route, but can't speak from experience on that. Regarding bringing bikes onto NJ transit: It's technically only allowed if you are stopping at a station that has a dedicated platform level with the train. For Belmar you are expected to go down steps, and hence you're not allowed to exit with a bike at that stop. The closest station that exits at a platform is Asbury Park. I would have assumed this would be the sort of thing conductors would turn a blind eye to (after all, what's the real harm of bringing a bike down three steps?), but I actually witnessed a physical altercation between the conductor and a rider trying to get off at Belmar with a bike, so at least in some cases they take it *very* seriously.

museum report

Jeff G. and I worked in the museum today from 8am-3pm. Jeff B. joined me for more work from 5pm-9pm. In the daytime slot, we installed the large monitor donated by David G. last year. It is 50" (horizontally) and works great. We put a shelf under it (great place for a videogame console to keep us entertained between museum visitors!) along with two shelves on the opposite side of the bench (with room for more shelves later if needed). We also did some set-up with the Prime 6550, added a handle (kind of silly-looking, but it works!) to the PDP-11/785, set up most of the office PC, and finished cabling the microcomputers. We also did some clean-up work. In the evening, we did a bunch more cleanup, rebuilt some of the outdoor signs for VCF East, and tested the Amstrad PPC 640 (it works but we need a system disk). Also, we got two more industrial-strength long power strips from Steve A., so now there are two on each side of the microcomputer aisle. That means nothing is daisy-chained, unlike in our old rooms. We just need one more for the workbench. Corey's picking that up in the next few days. Here are some pictures: http://vcfed.org/evan/screen.jpg (pipe on the right side is in front of a speaker, not the screen itself) http://vcfed.org/evan/powerpole.jpg (this is the new power pole on its own own 20A circuit for the center aisle of microcomputers, it has four outlets on the side, and next time we'll paint the wooden block underneath it to match the floor) http://vcfed.org/evan/handle.jpg (new handle -- also a new lock) http://vcfed.org/evan/galinat.jpg (kudos to Jeff G. for making a lot of long trips to the museum and doing tons of manual labor for us lately) http://vcfed.org/evan/protect.jpg (step away from the blue box...) http://vcfed.org/evan/allbench.jpg (new shelves on left, new shelf under TV too) http://vcfed.org/evan/twoshelves.jpg (room for expansion) http://vcfed.org/evan/oneshelf.jpg (let the Pong commence) Back at it this weekend! Need to set up another computer or two, put the decorative backings on all the microcomputer shelving units, start making the signs, do more cleaning, and who knows what else.
