I've searched for this but couldn't find it...
Does anyone know if the DEC book "RTM: Register Transfer Modules"
published in 1973 is available online? It's an 8.5 x 11 book with
red cover and has 50 pages. I think it came with their RTM kit.

Anyone remember the R65F11? It's a Forth microcontroller: 6502
processor with a Forth kernel in ROM, from the mid '80s.
I was going through some old stuff in storage (looking for something
else) and found an R65F11 with the development ROM and some
documentation for building a development board.

Your hometown magazine, ETI, ran several articles about it at irregular
intervals. The first was a development
WOW!!
I Have one of those ETI boards, and I based my final Electronics
Engineering project on its big brother, the 65F12.

Ok, so now the three old style 11/24 CPU boards seem to be working. Ish.
The problem with the processor boards turned out to be the switches: On
my original 11/24 board it would work only at 19200. This is because the
switch pack is dirty and the contacts ain't working.
