Doug and I were at the museum today. There were a good amount of visitors including my dad who hadn't been there since a few years ago. Doug learned about the Mimeo, and we have a productive discussion about how to do some fundraising. Corey texted to say he acquired a toolkit for our workshop.

LSSM outing
by Mike Loewen 01 May '16

01 May '16

I had a great time at Dave McGuire's Large Scale Systems Museum (LSSM) on Saturday. Lots of interested folks touring the museum. Several Federation members in attendance, including (obviously) Dave McGuire, Matt Patoray, Connor Krukosky, Sridhar Ayengar and wife Roopa, Ian Primus, Jeff Jonas and Dan Roganti. Corey Little was just down the street with his pop-up CP/Museum. We managed to sneak in a little work on one of Dave's newly acquired systems, an HP 2117F mini. The power supply checked out (and no foam!), but entering a program from the front panel indicated some sort of memory issues. The system came with a 2102E High Speed memory controller, four 64KW HS memory boards, M.E.M. board, Memory Protect and D.C.P.C. board. The I/O cage had the Time Base Generator, Firmware Expansion Module (FEM), BACI, Terminal interface and 13037C disc controller interface. All it needs is an HP-IB interface (12821) and possibly some additional ROMs, and it can run RTE-6/VM. Mike Loewen mloewen(a)cpumagic.scol.pa.us Old Technology http://q7.neurotica.com/Oldtech/

OT: narrow LED flood bulb
by Evan Koblentz 01 May '16

I'm doing a personal project unrelated to computers. I need to use an LED flood light bulb 1.5 inches at its widest point. Google says to buy a bulb size called "R12" commonly found in elevators. The project will use ordinary 110V AC. What do I use for the bulb socket? I'm having difficulty finding a straight answer.
