VCF East 9.1 - Exhibition

Exhibitor registration is open! We'll continue to post more exhibits as the event nears, so check back frequently.

The Vintage Computer Festival wants you to display the pride of your collection at VCF East 9.1. 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 a prize!

Registered Exhibits

HP 2109E Minicomputer
Mike Loewen (State College, PA, United States)
I will demonstrate a vintage 1983 Hewlett-Packard 21MX series 2109E minicomputer with a 7970E 9-track tape drive. There will also be 2647A and 2645A terminals. The system will be running RTE-6/VM from a HP-IB hard drive emulator. It can also boot from tape to run diagnostic programs.

Handheld Electronic Games from the 70s & 80s
Andy Molloy (Syracuse, NY, United States)
These magical games enthralled kids and adults for a short ten-year period between 1976 and 1985. I think Jaro Gielens of Electronic Plastic sums it up best: these games each had a unique display and custom programming, and only one game could be played. Their time ended with the appearance of the cartridge-based Nintendo Game Boy. They were "excellent toys that illustrated the colors and spirit of the time--of Walkmans, digital watches, Star Wars and sneakers." This exhibit will present a selection of these original games with many playable. If you enjoy VFD and LED displays, simple bleeps and button mashing, you will be right at home. These games are not well represented on emulators but several will be shown.

Multiplayer Network Gaming on the Commodore 64
Dan Roganti & Jeff Brace (New Kensington, PA, & Ocean, NJ, United States)
This is a homebrew coding project on the Commodore 64 to explore the world of multiplayer network gaming. Together with a C64NIC+ cart, which provides network connectivity, the C64 can be used to battle with other players across the internet. This new coding project, called Space Command, is a rendition of the popular arcade game Missile Command. The object of the game is to conquer the planet where the players battle each other to the death over the network.

PDP-8 Mark Sense Batch
David Gesswein (Bethesda, MD, United States)
This exhibit will contain a DEC PDP-8 minicomputer with punched and mark-sense card readers. Visitors can write a BASIC program on mark sense cards and submit it to be run.

Before the Revolution: Pre-Altair Microcomputing
Herb Johnson (Ewing, NJ, United States)
A display of the earliest microcomputing! Not-terribly-personal computers, industrial, degrees of homemade, most before the mid-1970s. Includes works by 1970s pioneers with kits, homemade, adapted technology, and industrial technology. All will be microprocessor or discrete logic or mechanical. It may not be pretty -- not all will play Hunt the Wumpus. But it will be historically correct.

Small Bus Data Center
Alex Bodnar (Oxford, Pa, United States)
See a Heathkit H-89 microcomputer with external disk drives running the WordStar word processing software. The computer will also run versions of the C, Cobol, and Fortran programming languages. Accounting software will also be displayed.

MARCH Presents: UNIVAC 1219-B
MARCH (Wall, NJ, United States)
MARCH (Mid-Atlantic Retro Computing Hobbyists) is a user group for collectors of vintage computers. We have many dozens of active members from Hartford to Pittsburgh to Washington D.C., everywhere between, and even some beyond. We formed in 2004 and we operate our own computer museum at the InfoAge Science Center, where we host the VCF East! This year at the show, our club booth will show off our mid-1960s UNIVAC 1219-B transistor mainframe. It's not working (yet!) but you know you wanna take a selfie with it!! Be sure to visit our museum right down the hallway from VCF East.

How Games Drove the Hobby Computer Movement
Corey Cohen (Matawan, New Jersey, United States)
Many early hobby computer owners just wanted to do something fun with electronics or a computer they could actually own. See some of these early "games" that drove people to learn to solder, read a schematic and show off to their friends what they built. We will start at 1974 with the Scelbi 8H and move to the early Apple II, the first computer to have affordable color graphics that you could actually buy. Systems such as the MITS Altair 8800, Apple 1 (replica), and Processor Technology SOL-20 will also be shown.

Children's Machines
Mary Hopper (Cambridge, MA, United States)
Remember turtles? This exhibit will feature a collection of rare hardware and software that embodies Seymour Papert's constructionist learning theory as he set forth in Mindstorms and other works. The collection includes numerous fun toys like a Roamer, and TI-99 Sprite Logo system, Fred Martin's Crickets and some vintage Lego/Logo systems. All items in the exhibit will be functioning and available for interaction (hopefully, knock on wood :-)

Dual Dazzlers
Bill Sudbrink (Silver Spring, MD, United States)
A very early example of color graphics available for the home was the Cromemco Dazzler S-100 board. I will exhibit two examples of this board in two different S-100 systems. One board is kit built and one is factory built. Both games and an early graphics animation package called Felix will be available for attendees to try out.

PEEKing Under the Hood Using BASIC
Bill Degnan (Landenberg, PA, United States)
This exhibit will demonstrate how BASIC can be used to access machine hardware, speed up programs, and control devices. Machines on display will complement my lecture on "Advanced BASIC" for VCF East University. Exhibit hardware will include a PDP 11/05 (DEC Papertape BASIC) with ASR 33 teletype, OSI 1P (Microsoft OSI cassette BASIC), Altair 8800b-Turnkey system (Altair Disk BASIC) and Heathkit ETA-3400 (Heath Tiny BASIC)

Bringing Vintage Microcomputers Back to Life
Mike Willegal (Tewskbury, MA, United States)
Sometimes it is simple to bring a vintage microcomputer back to life. That will be demonstrated with a Radio Shack TRS-80 Model 1. Other times we need extreme methods such as reproducing a whole computer! This will be demonstrated with a replica Apple II plus the custom-built reproduction Swyft card.

VAXen Through the Years
Sridhar Ayengar (Poughkeepsie, NY, United States)
Come see a smorgasbord of DEC! This exhibit will include examples of Digital Equipment Corp. systems such as VAX, MicroVAX, perhaps a DECstation, maybe an Alpha, and even a PDP-11.

Modern Stuff For Old Computers
Michael Hill (San Francisco, CA, United States)
An exploration of some of the modern tools one can use to bridge the gap with their old machines: Bluetooth on a Commodore PET? You bet!

Franklin's Apple II Clones and Prototypes
Bob Applegate (Medford, NJ, United States)
Bob was a Franklin engineer and will show many one-of-a-kind items related to the company's Apple II clones. His exhibit will include Ace 1000 and 2100 computers, various plug-in boards, a prototype "Key" portable computer, a prototype CP/M system, and another prototype clone called Red Lightning. He'll also have an assortment of Franklin marketing materials.

Commodore Curios
Rob Clarke (Tuggen, Schwyz, Switzerland)
Beside the ubiquitous home computers for which they are known, Commodore also manufactured watches, television "Pong" clones, chess computers, and more. You'll see these plus a selection of little-known Commodore computers that barely made it to production, including a KIM-1 single board computer, a MAX Machine, and a Commodore 232.

Vintage Mac Museum Rarities and Highlights
Adam Rosen (Malden, MA, United States)
A gaggle of classic Apple Macintosh systems, rare items and highlights from the collection! Stop by and play with the Macs of yesterday -- an SE/30, a Color Classic, and a first generation Macintosh PowerBook. Look inside the machines with a see-through Mac 512k, read the signatures engraved inside the case, and view an original Macintosh "Picasso" lighted display sign.

Unique UNIX
Anthony Stramaglia (Florham Park, NJ, United States)
This exhibit will feature a selection of vintage hardware running UNIX and UNIX-like operating systems. Examples are the familiar AT&T 3B2/400 and Unix PC, as well as unique systems such an Altos 886, a DEC Professional 350 running VENIX, a rare Sanyo/ICON 3800 that was capable of running PICK on top of UNIX, and a TRS-80 Model 6000 running XENIX. Time permitting, I will attempt to tie two or more systems together via serial interfaces and do old-fashioned cu and uucp file transfers.

The Apple 1 Computer
Christopher B. (Chicago, IL, United States)
Here's your chance to see a real Apple 1 computer -- not a replica -- as designed by Steve Wozniak. This particular Apple 1 was rescued from the discard pile in Steve Jobs' office. It is nearly working, and there's a good chance it will be ready to operate by the end of this show!

Early Desktop Publishing on Commodore 64
Michalina Jernigan (Belle Mead, NJ, United States)
Our youngest exhibitor! Eight-year-old Michalina (with a little help from her dad Justin...) will demonstrate "The Newsroom" for the Commodore 64 to exhibit early WYSIWYG publishing, which included cross platform (Commodore, Apple, IBM PCjr) compatibility including modem connectivity. I will print the "Vintage Computer Chronicles" from a dot-matrix printer. Attendees will be welcomed to take a copy of a VCF East newsletter and meet with a young attendee and vintage computer and press enthusiast.

Amiga Past & Future
Steve Mayo (Grafton, MA, United States)
For 30 years the Commodore Amiga platform has been in active development with new platforms and operating system revisions coming out. This exhibit will show the progression of the Amiga hardware and operating systems over this time period with functioning systems. Also, derivatives of the original AmigaOS such as AROS and MorphOS will be shown along with new expansions and hardware for old systems.

Apple Obscurities
Scott Baret (Pittsburgh, PA, United States)
This exhibit features a few obscure Apple products, just in time for the Mac's 30th anniversary. The following computers will be on display:

- Prototype Macintosh SE, non-translucent version. Exhibited last year at the VCF Southeast in Georgia and featured on an episode of Retro Mac Cast this past spring, this example of early Apple engineering is believed to be the only one of its kind. Unlike the clear prototype Macintosh SEs commonly discussed online, this machine is much older and is housed in an untexturized platinum case. (A regular SE will be around for the sake of comparison).

- Macintosh ED. An educational model of the Macintosh sold mostly in Europe, the ED was available as either a rebadged 512K or Plus. Although most believe the 512Ke was discontinued in September 1987, this computer shows the true longevity of the design. This particular computer was imported from Holland.

- A relatively common Apple computer in a most uncommon box with original sales materials and a complete set of floppies! This will be a surprise, but it's believed to be one of fewer than ten surviving examples with a box and could be the most complete machine of its kind.

- In time for the Mac's 30th anniversary, an original Macintosh 128K in a Picasso box will be on hand. If you've never had the chance to play around with MacPaint, now is your chance!

Gaming of Yesteryear
Linda Baret (Allison Park, PA, United States)
Here you'll get to play two classic videogame consoles: the Magnavox Odyssey and Atari 2600, both connected to period televisions.

Retro Tinker's CoCo Adventures
John Linville (Mebane, NC, United States)
A number of projects revolving around the Tandy Color Computer will be displayed. This may include original games such as Sluzzle or Fahrfall, custom joysticks and other hardware, and whatever else makes it onto the truck for the long haul to NJ... :-)

Don't Forget About Prime!
Ian Primus (Niskayuna, NY, United States)
With the popularity of DEC and Data General systems, people tend to forget the other guys. But Prime was a major player in the minicomputer market in the 1970s and 1980s, and made minis up until 1992. I'm bringing a working Prime minicomputer from the mid-1980s. Experience the multiuser operating system that time forgot. I'll have some user terminals and guest accounts, log in and play around!

Atari Computers 1979-1993
Curt Vendel (Carmel, NY, United States)
A look at 14 years of evolution of the Atari Home Computer Systems from their first models -- the Atari 400/800 to its last model, the Atari Falcon030. The exhibit will include many prototypes that never made it to market such as the 1450XLD, the STBook laptop, and one of the original "RBP" prototype wirewraps that became the Atari 520ST.

TI-994A w/ Expansion Box
Jeff Salzman (York, PA, United States)
Come see a Texas Instruments TI-99/4A home computer with speech synthesizer and TI Peripheral Expansion Box. This is a combination you don't see in operation too often. It has the full 32K memory, working RS-232 port, and floppy disk drive.

The Dawn of the Workstation
Francois Lanciault (Blainville, QC, Canada)
The HP-9845 is one of the first and arguably THE first desktop workstation. Introduced in 1977, it was equipped with dual 16-bits processors, high-resolution graphic screen, embedded graphic printer, and could drive a multitude of peripherals. Some models even included a light pen and color screen. Very fast for its time, it was primarily used by engineers and scientists until it was replaced by other workstations of the HP-9000 series. Come and see how it compares with other computers, namely the lower end HP-87XM and the HP-9816 workstation, both released five years later in 1982. The HP-9845 will also be hooked to an HP-9111A graphics tablet, a pen plotter, and 8-inch floppy drives.

Hello World from AHCS
Atlanta Historic Comp. Society (Atlanta, GA, United States)
The Atlanta Historical Computing Society will be bringing a few of its members to display a PDP-8/M with an emulated disk interface via RS-232 and USB connected to a Raspberry Pi, an IBM PCjr with modern-production sidecars like an IDE interface with a real-time clock and expansion RAM, and various other computers that will somehow manage to fit on a 6' table.

Lawrence Livermore Labs MST-80B Trainer
Jonathan Chapman (Troy, NY, United States)
The MST-80B is a compact, self-contained, Intel 8080 trainer with enough I/O to be usable as a laboratory instrument. It will be demonstrated with several homebrew expansion boards for interacting with the user and the real world.

Ohio Scientific Computers
William Dromgoole (Somerdale, New Jersey, United States)
This display will feature the Ohio Scientific Inc. 300, 400, and 500 series. All are based on the MOS6502 CPU.

Cosmac Cosmology
Ethan Dicks (Columbus, OH, United States)
From space probes to video games, remote weather stations to minimalist hobby computers, the RCA 1802 processor appeared in many guises over the past 38 years. This exhibit includes several examples of the 1802 including the Quest Elf, COSMAC VIP, Studio II video game system, and Spare Time Gizmos Elf 2000.

DEC PDP 11/05 system and DEC memorabilia
Ron Blechner (Sewell, NJ, United States)
Learn to play the PDP! Program a PDP-11/05 the old fashioned way: using the front panel switches. Several short programs will be available that work. Test the power off/on capabilities of PDP-11 corestack memory. The PDP-11/05 was first sold by Digital Equipment Corp. in 1970. For those who wish to compete, the fastest correct entry of a 28k memory diagnostic (21 location/12 line program provided to entrant) wins a $25 gift card to "Texas Roadhouse". A $250 gift card will go to anyone who is faster than 'The Master' (out of respect for others, time limits apply) ... Other DEC front panels and memorabilia will also be on display.
