Vintage Computer Festival East 7.0 - preliminary

This Web page last updated JUne 2 2011.


I was a vendor at the May 14-15 2011 VCF-East 7.0 show held by MARCH at Infoage in Wall NJ. I bought a number of systems to show and sell. This is part of my work in 1970's computer repair and restoration. Many of the systems I showed were S-100 computers, a specialty of mine. - Herb Johnson

Systems I brought included an Osborne 1; :black" Apple II Bell and Howell; a Sony SMC-70 CP/M system; Northstar Horizon on display. Also shown were two early IBM PC's, one with hard drive; an AT&T 386/25 desktop. All were working systems. On Sunday I spread the systems out a bit. I sold a few of these systems, passed along some additional hardware, and acquired some hardware as well.

In addition, I handed out flyers for Lee Hart's 1802 Membership Card, a handheld version of the classic ELF design with COSMAC 1802. Here's the flyer and 'card on display

At the show, Bill Degnan and I compared our Polymorphic 88 systems. See the details of my system and Bill's on this linked page.But real work on Bill's system at the show was done by Jonathan Chapman at his exhibit table.

TTY workshop

I participated in the teletype workshop operated by Bill Degnan. MARCH acquired a number of Model 33, Model 28, and other TTY's and offered them for sale and check out as part of this workshop. The Sunday workshop was very informative and I'm pleased with the TTY I got. These suffered a bit for years of storage and for mice, but were certainly useful or restorable.

Transistor Logic workshop

Dan Roganti ran a discrete logic circuit workshop, where participants built logic from resistors, diodes and transistors. This is part of Dan's interest in a discrete PDP-8 project.

The value of these shows is to bring together owners and restorers of vintage systems as exhibitors. We can compare notes and trade equipment. Also, many people who visit these shows were previous owners, some are restoring and some provide their former systems to MARCH or the participants. THere's a consignment area where MARCH sold a range of items as well as unneeded books and magazines from their archives and donations. Of course, there are talks by people of the vintage period, and they are also informative. But in my opinion, it's the contacts and opportunities for trade and technical support that make the show particularly valuable to me. Contact information:
