VCF East 5.0 - Exhibition

The Vintage Computer Festival wants you to display the pride of your collection at VCF East 5.0. 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.

A variety of Ohio Scientific microcomputers from the 1970s will be displayed.

To Float or not to Float: That is in the Answer
Dan Roganti (New Kensington, PA, United States)
A retrospective in 1970s microcomputing hardware, this will be a demonstration of an S-100 computer system using a floating point coprocessor. The software will create ASCII artwork based on the math functions using an FPU coprocessor.

Cold War Computing: Relics of SAGE
Mike Loewen (State College, PA, United States)
With more than 50,000 vacuum tubes and requiring 3MW of power and cooling, the SAGE (Semi Automatic Ground Environment) computers were the largest ever built, and kept a radar eye on our airspace for 25 years starting in the late 1950s. This exhibit will feature a pictorial description of the computers, artifacts from the system, and a multimedia presentation.

The z80 ain't dead yet!
Jeffrey Jonas (Elizabeth, NJ, United States)
The Z80 CPU was the "king of the hill" in the 1980s with the TRS-80 series of computers, but it never went away. It's still hard at work undercover as an embedded processor, and the peripheral chips are still the best around.

PDP-8 Computer
David Gesswein (Bethesda, MD, United States)
PDP-8 minicomputer and peripherals...

Mattel Aquarius - Harmony & Understanding
Andy Molloy (Syracuse, NY, United States)
The inexpensive Aquarius was in production for less than six months. This display will feature a working system, peripherals and games.

Surfing the Web on an Apple II
Sridhar Ayengar (Poughkeepsie, NY, United States)
This exhibit will involve using the Contiki operating system to attach an Apple //e to the Internet for the purposes of web surfing.

Don't Panic: Computer Games Without Pictures
Joe Giliberti (Jackson, NJ, United States)
Before computer graphics gave us video games that could challenge reality, computer gamers could entertain themselves with an adventure based mainly in their own minds. With just a simple outline and some descriptive phrases, these games came to life, for hours of fun and challenge. With that in mind, we will take a look at one of the classic games of the genre: The Hitchhiker's Guide to the Galaxy. Don't forget your towel and babel fish.

Citadel bulletin board system
Andy Meyer (Clark, NJ, United States)
I will demonstrate the Citadel BBS software on a dual-floppy CP/M computer. Quite innovative for its time, Citadel is written in the C language, and features a message base where discussions are organized into "rooms".

Savage Frontier
Michael Kelly (Jersey City, NJ, United States)
Savage Frontier (initially started out as PhillyChat! and went through a few names until becoming SF) was a Diversi-Dial 300 baud chat system run in the mid 198s until the great Internet machine crushed it and most every other independent chat and BBS around 1993-1994. After getting a bug about it one day, and observing the work of others in the area - ENTchat ( was a ddial clone written for UNIX, and STS/Gtalk systems were upgraded to take advantage of the Internet, I decided to set out making a 100% emulation clone. With the help of a friend, we modified an Apple II+ emulator to support 7 virtual AppleCat modems. I then spent time expanding the virtual phone huntgroup software (in C) to take advantage of multiple systems, and created a bot (in Ruby) to login to the system as a "remote" or extension, and interfaced it with the huntgroup software to extend (not modify) the original Ddial functionality to keep track of users and even play online games. For this exhibit, we will bring Apple, Amiga, and Model T computers as well as a Diversi-Dial server running on a Pegasos box, to demonstrate how 6502 is still affecting the lives of people today.
