I found this HRD board under a stack of other TI stuff today and had totally forgotten about it. I think I got it a one of the Chicago Faires several years ago. It does not seem to work and I'd like to fix it if possible. The battery is definitely dead. Pin 8 of the chip immediately below and to the left of the Zippie sticker is bent upwards and there was something soldered to it in the past, but I can't seem to find a loose wire anywhere.
I can't tell which version of the HRD it is. Clearly some modifications have been made and there is a mysterious "Zippie" sticker on it. Can you guys help me identify this board properly?
