Re: PALs to GALs...Pole Position 7C

<x-flowed>I'll dredge up a datasheet at work, but the 82S153 is a FPLA, NOT a
PAL. It's been a REAL long time, but if I remember correctly PALs and
GALs were AND arrays feeding OR arrays. The FPLA back then was an OR
array feeding an AND array, basically the same thing as a PROM. (The
difference is a PROM has ALL states (addresses) represented while the
FPLA only does a relatively few of the possible states, ie most of the
outputs ignor many of the inputs).

In any case just hang on, I'll find you a datasheet.

If you ever want to (un)subscribe yourself with TTL, you can send mail to:
<Majordomo@flippers.com>
with the following command in the body of your email message:
(un)subscribe techtoolslist
or from another email account, besides xxx@yyy.com:
(un)subscribe techtoolslist xxx@yyy.com
