M9312 boot/console PROM archive

[Don North]

I've posted a web page <http://www.AK6DN.com/PDP-11/M9312/>  that has 
M9312 PROM images in Intel HEX format as well as commented source and 
assembly listings of all the well-known devices, both boot and console.

Two 'new' images are also included, a revised version of the 'DD' TU58 
boot device that allows for a non-standard CSR assignment (the original 
DEC PROM is very broken in this regard) and a new 'ZZ' device boot PROM 
that runs the M9312 CPU and memory diagnostics continuously (useful for 
basic CPU/MEMORY check with no other peripherals).

A pointer to the tool set is also provided.

I'm still looking for *any* form of image for the TMSCP boot 23-E39A9; 
if anyone has one of these and can forward the bits (or a real device; I 
will return it!) I can process it, and we'll have a virtually complete 
set of all the major devices.
