Hmm, I tried to post this yesterday ... probably something went wrong..
I am looking for a 63C09E or 63B09E. Anybody knows where I can buy it??
I found a source in Australia, but that is the 63B09. The suffix "E"
is important, it is the *external* clock version, as used in the Core
Board of the Blinkenlight project (40 pin DIL case).
I have a PDP-8/e simulation running on th Core board, but could use
a performance increase. Upgrading to the Motorola "B" parts will allow
to double the clock frequency, but the Hitachi 63B09 is even faster,
as it does many 6809 instructions in less cycles.
Interested in the sim? Check my 'Homebrew PDP-11' page, the link there
is "spin off" ...
