[Heathkit] [Fwd: Heatkit part # 443-92 (MC9860P]

[MICHAEL TALLENT]

That is a Motorola RTL logic device, runs on 3.6 volts.  You probably can
sub a TTL 7441, but all pins are different and it runs on 5 volts, but it
will probably be easier to find, as I have some of the 7441.  If there is
room you can get a 16 pin "header" and glue the 7441 upsidedown on it and
then wire the pins to mate with the MC9860 pinout, BTDT.  Both have been
obsolete for over 30 years.
