June and July have been very busy for us, but not busy at the acid bench or microscope. Now we're back in the lab and getting down to business, knocking a few chips off the top of the amazing pile of historic devices we've received from donors lately. Here's a very early microcontroller from TI.
Keep an eye on our Chip Status List.
Great shot! Any idea what this chip was programmed for? I decoded the output PLA and it's not set up for a 7-segment display. The resolution is good enough, but I'm not sure I'm up to decoding the 8192 bits of ROM! Also, that's a 28-pin chip, but there are 30 pads - I guess VSS and VDD were each connected to 2? Thanks! Sean
