Subject: Re: Where to find 44pin edge cards/ 6502 d/l freeware
Having made and sold a combination backplane/extender
board for a bus
based on
this connector (2 x 22 @ 0.157" pitch) , I still
have a few of the things
lying
about, hence haven't had to look for them in the
stores. Nevertheless, I
do see
them from time to time at various surplus outlets.
Here in the
Denver-Boulder-Longmont area, the surplus outlets are down to just a
couple,
namely Gateway electronics and J. B. Saunders
Electonics, and, at last
check,
both had a few of them in stock. I doubt you will
have trouble finding
them
wherever you are.
Silly-con Valley.
I got a lead on a local computer surplus outlet.
I'll be bopping over there for lunchtime tomorrow. :)
Thanks for all your support.

Used to be, you could go to Radio Shock and
purchase one of those
solder-yourself 44-pin edgecards that mate with the KIM-4 expansion
board. I'm thinking one way around my dead keyboard issue which
also solves my desire for expansion would be to add a CPLD
decoder, 32K SRAM, 32K ROM (with holes around the 6530s
and remapping new patched monitor into $1800-$1FFF), and 6551
UART/MAX232 combo to input code and d/l intel hex. (The cassette
interface on poor KIM is dead, too.)
By the way, if anyone's interested, I have a generic 6502 Intel Hex
program downloader program that allows you to assemble and directly
download programs from the development PC into your SBC.
It's freeware so have at it if anyone finds it useful.
