In November, an LED sign from the early 90s was saved from the recycling centre and left off at Noisebridge.

A few basic details of what we know about it:

  • It ran on a custom hardware array of LEDs, 128 wide by 48 high, all red. When turned on, all LEDs illuminate, demonstrating that they are working.
  • The sign contains a defunct 386 that connected to the array via an ISA slot. Additionally, it was controlled by both/either a floppy disk and an onboard ROM chip.
  • The screen is labeled as a JVF 2010-A sign.

Someone was kind enough to collect a good deal of information on how to operate the sign at: http://johniii.tripod.com/jvf.html

Included in that page is a set of files to be put onto a floppy to operate the sign.
