Class ideas for East XI/11
by Evan Koblentz 14 Jan '16

14 Jan '16

Haven't decided yet whether to call our next show XI or 11.0. Leaning toward the first one. :) Anyway, we need some ** new ** class ideas AND PEOPLE TO TEACH THEM for the Friday sessions. (We're not using vintage.org anymore, but you can see the last two years' classes at http://www.vintage.org/2015/east/session.php and http://www.vintage.org/2014/east/session.php -- focus only on the Friday parts.) Fire away.

OT: Virtualbox problems
by Evan Koblentz 13 Jan '16

13 Jan '16

Certainly not vintage, asking here because you guys are smart! I had Windows 7 Pro 32-bit installed on VirtualBox under Ubuntu. It worked fine, albeit very slow. Last week I bought a new motherboard, processor, and RAM. What I had was about 8 years old and only 2GB RAM. The new specs include a 64-bit processor and 16GB RAM (expandable to 64). I didn't have to reinstall anything -- plugged in my SSD and the OS and all programs worked fine, just a whole lot faster! The only thing that broke is Windows under Virtualbox. It kept saying "aborted" upon booting. I uninstalled it and replaced it with the 64-bit version. Same problem -- it aborts during boot, can't even install it. Googling wasn't particularly helpful. Any ideas?

Re: [vcf-midatlantic] TTL components in Philly?

> > Any chance someone knows of a businesses that I’m not aware of in Philly that would stock TTL components like the 7430 8-input NAND? I have a SLOW order coming with one, but feel impatient, especially with time to burn and projects lined up in the retro pipeline. > > > Try Selectronics > http://selectro.com <http://selectro.com/> > > Just please don't buy out all their stock :) > > David I stopped by Selectronics today, but the nice gentleman at the counter said they really weren’t interested in selling small numbers of parts to individuals. From what I could gather, it looks like they recover ICs through e-waste processing, then sell them on the wholesale market. The guy was polite (and checked availability of the parts I was looking for), but clearly wanted me moving along. I guess it’s Jameco / Digikey / Unicorn and PATIENCE for now! But thanks to Bill W for sending me the 7430. Eric

FS: CCS Model 2016 16K Static RAM S100 Board Tested/Working in Box
by Systems Glitch 12 Jan '16

12 Jan '16

Just finished testing it: http://www.ebay.com/itm/272102935924 Tested and repaired by me, including bank select functionality. Programmable bank select feature so you should be able to set it up for either Cromemco or North Star bank select, or your own thing. Tested on my IMSAI 8080, so it works with front panels. Uses common 2114 static RAMs. Includes what looks like the original box, warranty card, some parts identification sheets, and a large ziploc bag. The box says, "Meets IEEE proposed S-100 signal standards," but I'm pretty sure that's only for 8-bit operation. I don't think it's compatible with 16-bit data buses. One of the address switches has a broken paddle, but is 100% functional. I'll replace it for free if desired. Thanks, Jonathan
