Re: HP LED displays Message #11 Posted by Katie Wasserman on 21 May 2009, 11:03 p.m., in response to message #10 by Tony Duell
Tony,
Yes, I think that's it. The BNC connector is hooked directly to the +5V on the power supply board. Here's a picture of the inside of the display:
HP LEDs 6
The date codes on the chips indicate that this was likely made in early 1983, I thought it would have been made earlier, but I guess the smart LED displays that it shows off must have been hot items around that time. It's running a 6802 microprocessor with 8K bytes of EPROM, not exactly state of the art in 1983 but it got the job done.
