I'm again trying to debug my PDP-11/23, and I believe I'm having trouble with my M8067-LB/MSV-11 memory. According to the manual, there is a diagnostic program called CZKMA (for my 18-bit system), but I can't seem to find it. I have all of the xxdp images from AK6DN, but this one doesn't appear to be on any of those. Some searching shows references to it and even a (poorly) scanned source listing, but does anyone know if I can get it on a TU58 image or another format?

Others have already given pointers and help. I thought I should point out that when a diagnostic is called CZKMA, the actual filename in XXDP will not have the leading 'C', and in addition it will have two characters appended, which gives a version. So, the normal way to refer to the diagnostic CZKMA as a file in XXDP would be ZKMA?? Johnny

Don't these diagnostics only print messages out if the switch register is set in the "proper" way. And as the 11/23 do not have a switch register, most diagnostics added a software switch register that could be accessed by hitting some key. Have you looked in the PDP-11 Software Diagnostics Handbook? Johnny On 2015-08-19 21:13, Ben Sinclair wrote:

Thanks everyone! It's running right now, and seems to be passing, however the parity error LED on the board is lit. The docs mentioned that ZKMA's messages (plus the source) would lead me to a potential bad module, but it doesn't seem to be failing. VMJAB0 doesn't run at all on my system. It turns off the run light as soon as it starts.That's why I was wanting to try the diagnostic mentioned in the MSV-11 manual.
