I'm planning to arrive Saturday afternoon/evening and leaving late Sunday. I'll need a ride from the train station. Anybody else likely arriving late Saturday? Also: I'm going to bring 3 NeXT keyboard & mice (non-ADB)? The museum gets at least one pair; anybody else like the other pair? I also plan to bring some unpopulated S-100 cards (mostly serial ports) and a bare 8" hard drive. Anybody interested in these? 01-Jeff B. - Commodore 64 Robotics Kit for HOPE Exhibit 02-Evan - Lego LOGO robotics kit for HOPE exhibit (Apple II, IBM PC) 03-Alex J. - PS/2 model 70 and AT&T 6300 testing/repairs (Sunday) 04-Dean - TRS-80 Model 4, Model 4D, Model I 05-Todd - Not entirely sure, but definitely will bring my AT&T 6300 06- Bill Drom. - Plan on working on Univac 1532 mods for 60 Hz operation. possibly also clean up the 400 Hz motor gererator set. 07-Duane - same as Bill Drom. 08-Steven M. - need opinions on salvaging an Audio Visual Workshop (AVL) version of an Eagle computer. I rescued it from the back of an AV staging co warehouse. So far all it does it make smoke. Amazingly, there was a spare motherboard packed in the road case... 09-Ian - 2600's Z-100 10- Stephen E.

pickup in DC?
by Dave McGuire 06 Jun '16

06 Jun '16

Hey folks. Awhile back I needed some help getting a vintage oscilloscope retrieved from Oklahoma. I'm pleased to report that, with the help of a friend, it has been retrieved. Now that friend is traveling in Washington DC, and he brought it with him. Is there anyone in or near DC who might be able to meet up with him downtown and grab it? I'll be in DC again in 2-3 weeks and can pick it up at that time. Thanks, -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Apparently Authentic Apple 1 on eBay
by J. Alexander Jacocks 06 Jun '16

Not sure if anyone here cares, but there is a seemingly-authentic Apple 1 on eBay, right now going for about $17k. http://www.ebay.com/itm/282050295252 Looks non-working, but reparable, to my untrained eye. - Alex

workshop prep
by Jeffrey Jonas 05 Jun '16

Who needed EPROMS such as 2764? I have plenty to spare, but do you have a UV eraser & programmer? Who asked for Z80 chips at a previous workshop? I have more. I'm sorting my old chips, just ask if you need anything such as 16k, 64k DIP DRAM. I NEED: 0.3" chip rails. I also need help identifying chips: Universal Pioneer UM4004, but it's a 0.6" 28 pin DIP Thanks, and see you at the workshop! -- jeffj

FS: Bytek S-10 EPROM Programmer Standalone/RS232 Control
by Systems Glitch 05 Jun '16

05 Jun '16

link: http://www.ebay.com/itm/272264880145 This one arrived in a lot of surplus test equipment from Virginia Tech. It had an exploded electrolytic in the power supply -- vented electrolyte all over the inside! I cleaned it up and replaced the blown capacitor with a NOS reformed unit, and it seems to power up and be functional. Unfortunately, I can't locate a manual on it, so I can't test programming functionality -- you have to select the EPROM type with a numeric code, which I don't have. Hence the listing as "for parts." Inside, this is a little 8085 based system. Your typical array of standard and MCS-80/85 family parts. I want to say it uses a regular EPROM, so that should be easy to dump if someone is interested in reverse-engineering the EPROM definitions, or writing custom firmware for it. Very clean design. I've already got a number of programmers so I figured I'd pass this one on to someone else to hack on. Thanks, Jonathan

FS: Leader LS-1020 20 MHz Analog Dual Trace Oscilloscope
by Systems Glitch 04 Jun '16

04 Jun '16

link: http://www.ebay.com/itm/272264264580 Simple 20 MHz analog dual trace oscilloscope. Fully tested with my Tektronix function generator. Picked it up in a lot of surplus lab gear. This would be a fine little 'scope if you need something to look at relatively slow digital signals or for general hobbyist level analog work. Thanks, Jonathan
