Hi. I have a panel display of BCD thumbwheels I'd like to decipher into
binary: 4 or 5 decades of BCD to 12 or 16 bits of binary.  TI used to make
some ROM based parts for this, the '484 and '184 parts, but they're out of
production. They also took something like 11 parts for 4 decades, by
cascading a lot of 6 bit to 6 bit decoders.

Does anyone have either the Jedec files for a reasonably sized EPROM decoder
for 4 decades, or a clever implementation of a several decade decoder in a
PAL? I don't have the board space for ~11 chips for a set of one decade
decoders wired up for decoding 4 decades.

But I could fit ~5 2 decade decoders to get the 4 decades. I'd really prefer
to wire up ~5 and get *5* decades, though.

In addition: has anyone got a decent PAL setup for controlling and
pre-loading the Harris 82C52 UART? It would save me board space and power
over the 6402 I'm using now: the PAL's I'm using are GAL22V10's.

Thanks for the help....
