I was trying to put together a minimal PDP-11/03 using a quad width
M7264 CPU and got nothing, no ODT prompt.? I'm not sure the board is
working.
Searching the internet I came across this page which described a M7264
CPU board with a 'bad' MICROM
http://www.datormuseum.se/computers/digital-equipment-corporation/qbus
Quoting the page; "Using a logic analyser showed that the MICROM without
label is not behaving well."
Anyone know how a logic analyser would be used to determine this?? Other
hints to debug this board?
