Hi,
I am preparing to get some S-100 6502 CPU board PCBs manufactured for the N8VEM and
S100computers.com builders. These are CPU bus master only (no TMI circuitry) and include
provisions for a 4K boot ROM. There is no onboard SRAM or other IO. The board includes a
large prototyping area for builder customization.
Assuming we can get 20 solid board builder commitments, I will place a PCB manufacturing
order in the next few weeks. Please contact me by email if you are interested in
participating. This is a hobbyist board built by hobbyists for hobbyists. The PCBs will
be $20 each plus $3 shipping in the US and $6 elsewhere.

Question... a related link.....

Where does one get just the 6x4 keypad in that picture? Is that
something custom made just for this project? Is it available for
purchase? I am looking to hook up a nice external keypad to my Micro-
Kim after mounting it in a chassis. Can't seem to find a good 6x4
matrix encoded keypad, hopefully with covers that remove so you can
put your own labels "under the plastic". I'm thinking of a keypad that
has a similar look/feel to the one on a heathkit H8. I was thinking I
would just get some perfboard and individual cherry switches and wire
it up, but if prior art exists at a reasonable price....
Best,

FWIW, the Heathkit H9 terminal and the Heathkit ET3400 trainer have the
same keys. The ET3400 is a common item on EPAY.
