VCF 7.0 - Exhibition

The Vintage Computer Festival wants you to display the pride of your collection at VCF 7.0.  Every collector has a machine or two in their collection that is in exceptional condition, or is extremely rare, or has a good story behind it, etc.  Or perhaps you're a programmer and have written a great simulator of some grand old machine.  Or maybe you've built a wonderful re-creation of a significant machine of the past.  Now's your chance to show it off to other hobbyists!

Not only is this your chance to show off the pride of your collection, but your exhibit could also win the coveted Best of Show award! First, Second and Third place prizes will be awarded with a ribbon based on the votes your exhibit garners from VCF attendees.

PDP-11/40 Running Ancient Unix
Pavl Zachary (Aptos, CA, United States)

A Digital Equipment Corporation PDP 11/40 computer, complete with vintage peripherals including disks, high-speed line-printers, and ancient terminals, inviting you to login to a UNIX system, the likes of which haven't often been seen since the mid-1970s when Digital was the world's largest minicomputer manufacturer and UNIX was just becoming the rising star of the nascent Internet. This is a trip back to a time before windowing operating systems, 5.25" floppy disks, and even vi!

Pre-Altair Personal Computers
Jack Rubin (Wilmette, IL, United States)

This display includes the Scelbi 8-H and the RGS-008, two 8008-based computers accompanied by an extensive collection of documentation, marketing literature, contemporary reviews, relevant publications and transcripts of interviews with the designers/creators.

First TRS-80 on the Internet
Frank LaRosa (Belmont, CA, United States)

In 1985, a BBS called Searchlight running on a TRS-80 Model 3 was brought online. In 1997, the old TRS-80 was pulled out of the cloest, refurbished with some "modern" floppy disk drives, and the BBS was re-born on the Internet using a modem emulator running on a PC that fooled the TRS-80 into thinking it was taking calls over a modem.

The Searchlight BBS will be reanimated once again at VCF 7.0, connected live to the Internet to allow incoming "calls".

Osborne I Portable Computer
Fritz Schneider (Sunnyvale, CA, United States)

The first microcomputer with a serious software bundle was the Osborne I. It featured a fast Z80 CPU, two floppy disk drives, and was portable. It came with CP/M, SuperCalc, WordStar, Basic, and dBase II.

The Evolution of Handheld Math
Boris Debic (Foster City, CA, United States)

Sixty years of palm-sized computational history presented through devices, simulations and applications. From a WWII concentration camp survival story to symbolic algebra on a contemporary PDA. We'll spin counters and go back to a time when assembly language was more like:

"A calculator will automatically subtract by addition, when it doesn't transfer to the main counter the number set to subtract but, instead, its nine's complement, and subsequently adds a one to the lowest position. The complement segments are not in operation during addition because they move between the possible positions of the setting gears. When the stepped drum is shifted up over one and a half times the distance between the segments, then the complemented toothing engages with the setting gears, and each gear of the setting mechanism does not rotate over the number of teeth corresponding to the number set, but over its nine's complement."

Semi-Virtual Diskette - Vintage Floppy Emulator
Eric Rothfus (Austin, TX, United States)

The SVD is a device that emulates a vintage 5.25" floppy drive that would normally be connected to a TRS-80, Heathkit, or Apple ][ computer. One can download a floppy image from a "modern" PC to the SVD, and the vintage machine can boot directly from it.

The SVD can be used to run vintage software or to create backups of vintage software that can be saved to modern PCs.

More information can be found on the SVD website.

Raster vs. Vector Display Technology
Kathy Fulton (Cupertino, CA, United States)

This exhibit demonstrates the difference between raster and vector display technology by using contemporary non-computer technology: an Etch-a-sketch and Spirograph to simulate vector display technology versus a LiteBrite to simulate raster display technology. The exhibit will include a Vectrex to further illustrate vector technology.

The exhibit is directed towards younger visitors to provide a gentle introduction to the two types of display technology.

IBM 1130 Simulator
Brian Knittel (Berkeley, CA, United States)

An IBM 1130 simulator including a paper tape reader, Documation card reader and an Epson dot matrix printer.

Southwest Technical Products Corp.
Michael Holley (Seattle, WA, United States)

SWTPC (1964-1986) started selling electronics kits based on construction articles published in Popular Electronics and Radio Electronics. Dan Meyer, the founder, designed a series of audio projects. Soon Don Lancaster started providing IC based designs of test equipment and the famous TV Typewriter.

In 1975, SWTPC introduced the 6800 Computer System and the CT-1024 Terminal (which appeared in a construction article in the February 1975 issue of Radio Electronics). SWTPC continued selling computers until 1986.

A collection of vintage catalogs, brochures, and magazines will be on display. Various SWTPC kits from the 1960s and 1970s will also be shown.

More information on SWTPC can be found at http://www.swtpc.com/mholley.

Imlac PDS-1D - Maze War
Tom Uban (Valparaiso, IN, United States)

The Imlac PDS-1D was one of the first integrated vector graphics computers, circa 1970. This example will be running what is called the first 3-D multi-player game, Maze War, as well as a number of other programs, including Space War, pinball, SNARF, terminal emulator, etc.

Computing by Steam
Tim Robinson (Boulder Creek, CA, United States)

A working model of Charles Babbage's first difference engine, inspired by the fragment he completed in 1832, will be displayed and demonstrated.

The model is constructed entirely from Meccano parts and computes using the "method of differences". With three orders of differences, polynomials up to the third degree can be tabulated.

It is hand cranked, as was Babbage's demonstration engine, producing results at a rate of about one every four seconds. Babbage envisaged that a full scale machine, which he never completed, would be driven by a steam engine.

More information on this replica can be found at http://meccano.us/difference_engines/rde_1/.

Differential Analyzer
Tim Robinson (Boulder Creek, CA, United States)

The differential analyzer is a mechanical analog computer for solving differential equations. It was invented in 1931 at MIT by Vannevar Bush. Many similar machines were built in both the US and Europe in the 1930's and 1940's, and some were still operational as late as 1960.

This recreation is constructed almost entirely from Meccano parts (as were some of the earliest copies in the UK). It follows the layout and functionality of Bush's prototype. It has four integrators, an input table and a dual output table.

It will be operational, set up to solve a simple differential equation illustrating all the principal functions.

More information on this replica can be found at http://www.meccano.us/differential_analyzers/robinson_da/index.html.

Atari ST Personal Computers
Philip Louie (San Francisco, CA, United States)

Bastardized 64
Hans Franke (Muenchen, Bavaria, Germany)

This is Commodore 64 enclosure updated with a 1.2Ghz mini-ITX motherboard running a Commodore 64 emulator under Linux.

Alpha Microsystems AM-1000
Bob Fowler (San Leandro, CA, United States)

The AM-1000, released in 1982, is a general multi-user desktop microcomputer based on Motorola's 68000 CPU. The system commands, architecture, and disk directory structure are intentionally designed to be very similiar to the DEC PDP mainframes of the 1970's. The AM-1000 was one of the first multi-user implementations of the 68000 CPU, but was actually a second generation computer, replacing Alpha Microsystem's earlier AM-100 (1977), which was also fully multi-user.

The exhibit will include a vintage 1982 AM-1000, two 1980s era terminals, an HP-2500 color laser printer (2002), and extensive original AM-100 and AM-1000 documentation. A number of interesting applications will be available for demonstration, including horoscopes (in color), nutritional food charts (in color), and multi-precisional calculations.

Bob Fowler served on the board of AMUS (the national Alpha Micro Users Society) since 1980, and managed the local AMUS chapter for San Francisco during the period of 1980-1993. A complete set of newsletters from both those organizations will be at the exhibit.

SWTPC TV Typewriter
Michael Holley (Seattle, WA, United States)

The TV Typewriter was a landmark in the personal computer movement. The original version (1973) had limited success; the second version (1975) came along at the right time and was very popular.

A fully restored CT-1024 (TV Typewriter II) will be shown plus another one under restoration. Also included is a collection of original documents and magazines for both versions. Don Lancaster's TV Typewriter prototype is in the collection of the Computer History Museum.

More information on the TV Typewriter can be found at http://www.swtpc.com/mholley/CT_1024/CT1024_Index.htm.

COSMAC Elf Replica
Bob Armstrong (Milpitas, CA, United States)

On display will be a replica of the COSMAC Elf.

Microprocessors and Microcontrollers
