VCF Southeast 4.0 Exhibits

Registered exhibits:

What could have been — Earl Baugh — Johns Creek, GA
This exhibit will display items that didn’t succeed at their initial introduction, and/or were alternate designs for products that were released much later.

Desktop and Handheld Calculating MachinesKyle Owen — Auburn, AL
Computers and calculators have been linked from the very beginning. A fine line exists between programmable calculators and computers, and at this exhibit, the line will be blurred even further. Come see a PDP-8 emulate an HP-35, a home-brewed Intel 4004 calculator, the first transistor-based calculator, and various other calculating machines!

Replicating vintage computers with modern parts  — Oscar Vermeulen  — Walchwil ZG,  Switzerland
Working systems from the 60s and early 70s are getting hard to find. But making a replica can be a good way to experience what it was like. Replicas come in two flavours: authentic reproductions using original parts, and work-a-likes using modern components. This exhibit will show examples of the second variety. Play with the PiDP-8/I, a reproduction PDP-8/I hiding a Raspberry Pi inside. Or with the KIM Uno, a KIM-1 for less than $10 in parts. Also shown is work-in-progress on PDP-11 and LGP-30 projects. All are open-source hardware projects you can make with low-cost, commonly available parts. Details at

TRS-80’s in the Modern Age — Randy Kindig — Lebanon IN
This will be a demonstration of TRS-80 machines, one of the machines that made microcomputers popular, beefed up with modern upgrades.  There will be a TRS-80 Model I with the Model I System Expander (MISE) demonstrating networking, VGA, high-res and other upgrades to that machine.  There will also be a TRS-80 Model 4P with a FreHD SD card based hard drive emulator and a high-res board.  In addition, software will be running on these machines that demonstrates modern capabilities such as a Dropbox client (TRSBox) and a Wiki client (TRSWiki).

A History pf Handheld Electronic Calculators — Ben Bradley — Jasper GA
Handheld electronic calculators were introduced in the early 1970s at prices over $100 for even the simplest “four function” models. By the 1990s four-function calculators were so inexpensive they were given away as promotional items. This display chronicles that development and beyond to the present day when smartphones are many times more powerful than any calculator, yet some calculator models are still made and sold. Featured will be items from the long-running Hewlett-Packard and Texas Instruments lines as well as many other brands such as Bowmar, Rockwell, National Semiconductor, Casio, Sharp, no-names and even Commodore before it dropped calculators to focus on those new-fangled personal computers.

NewComputer Museum: 3D Edition — Mary Hopper — Cambridge MA

The clicky-clack Tic-Tac-Toe Computer! (1961) — Jim B. Steiner — Atlanta GA
Jim returns with a show favorite, the Tic-Tac-Toe computer!   This device was designed from scratch, using parts and electromechanical relays from 6 pinball machines (and a piece of furniture). The computer  started as a project for the high school humanities class, but when the science fair coordinator heard of it, he encouraged Jim to finish it in time to enter it in the school science fair.  Additionally Jim was further inspired by the 1960 winners,  the inspiration for the movie “October Sky” Rocket Boys from the small town of Coalwood, West Virginia.  Needless to say, their success led him to have it finished in time to enter the school science fair. The Tic-Tac-Toe Computer then progressed from the High School Science Fair to the Regional Science Fair and to the State Science Fair.  Come see it still in operation and try your luck at beating it!

January 1984. — David Iwanicki — Marietta GA
This exhibit will return to a pivotal point in personal computing history –  January 1984.  It will compare and contrast 3 iconic machines released that month and experience what the best-selling, biggest-named, and most-innovative companies presented as the direction personal computing was headed.   Featuring the Commodore SX-64 “Executive”, the IBM PCjr, and the Apple Macintosh.

ADTPro and OpenCBM — David Iwanicki — Marietta GA
With vintage equipment, sometimes you want/need to recreate the physical media.  With newer equipment this can be normally done by “downloading” and writing to disk.  With older systems, that isn’t as easy.  This exhibit will show how to recreate physical media by interfacing with Internet-capable systems. Emulators are handy, but it’s so much more fun to run real disks in real equipment.  NOTE: For demonstration or allowed purposes only, copyright infringement is always discouraged!

Robotics! — Luis Guzman — Johns Creek GA
Our friends from the Atlanta Robotics Club will be on hand to exhibit some of their equipment and discuss their past and upcoming activities.  A number of the AHCS members are also members of this group, and AHCS welcomes them!
