by William Dudley 11 May '17

Zenith ZWL-183-93 laptop. A very early luggable, with (I think) a plasma monochrome display, 3 1/2 " floppy, and hard disk. Runs MSDOS. The museum gets first crack at this. See attached photos. This belongs to a friend, who asked me to find a home for it. Bill Dudley This email is free of malware because I run Linux.

Video: Writing C++ '17 for C64
by Douglas Crawford 11 May '17

11 May '17

At our VCFE C++ keynote lecture, Bjarne Stroustrup elaborated many of the goals of C++, one of which is "zero overhead abstraction". All doubts on the practicality of that goal has now been dispelled from my mind with this fascinating video on demonstrating zero overhead in writing a C64 game in C++, cross compiled to '386 then translated to 6502. You have to be careful, but a high degree of this zero overhead is proven to be possible. If you, like me, have been ignoring the evolving constructs of C++, this will give you an appreciation of what has been developed and in my case is pointing me into directions to what to catch up on. https://youtu.be/zBkNBP00wJE

OT: electric motor question
by Evan Koblentz 10 May '17

10 May '17

I wanted to test one of the Lego motors without setting up the whole kit. The motor is designed for 4V DC. Dug through my bin of random wall warts. Closest I could find is 5V DC (and 0.5A but I'm not sure if that matters). Snipped off the wart's barrel connector, spliced a mini-banana lead to each wire, and the motor happily spun away. When I tested the Lego computer interface port voltage it showed around 3.7x on my multimeter whereas the wart produces 5 true. Will I cause any long-term damage to the 30-year-old Lego motor by running it at 25% higher voltage than intended?

Workshop day 2
by Evan Koblentz 10 May '17

10 May '17

Today's workshop attendees were me, Jeff B., Bill Dromgoole, Bill I., Dean/Drew, Adam, and Tony. Bill and Bill continued working on Univac + EAI TR-20 projects respectively. Dean/Drew worked on a TRS-80. Adam tested one of his Amigas. Several of us (me, Dean, Drew, Adam) worked on museum-owned Amigas. We got a 500 working and then a 1000 working, both with workbench disks previously provided by Anthony/Bill of Guru Meditation renown. The 500 is in our museum temporarily. The 1000 will replace it when we get a suitably new-yellowed keyboard. Dean took home one of our keyboards and will try to retrobrite it. We along with Tony (and Google!) tested the museum's NeXT Station. It works pretty well. We'll display it soon as the next "artifact of the month".

uploaded some pics from Dave's LSSM museum Lots of new exhibits and the new expansion with Corey's exhibits on the 2nd floor I still have to add the captions on these Some the pics need to be redone, I didn't notice the lighting was changing too much. And because some of the shots were done while still in macro-focus http://www.rogtronics.net/blog/?page_id=1065 Dan -- _ ____ / \__/ Scotty, We Need More Power !! \_/ _\__ Aye, Cap'n, but we've only got 80 col's !!
