I have an old Microbotics / Paravision M1230XA accelerator board, and it's not working properly. Can you help me debugging it?
For starters, a few screenshots would help: SetXA utility window /
running, Early Startup Menu boards listing, "showconfig" output, SysInfo
screen with speed test results (each of course with a working M1230XA
I mostly test my board with Kickstart 3.0 - are you aware of any issues regarding KS3.0 and the M1230XA?
(apart from the fact that RAM has to be added "manually" / software-wise)
Please leave a comment in the comments section below, if you think you can help.
Or contact me via this thread at amiga.org:

The Microbotics M1230XA seems to work fine without memory installed.
With memory installed, adding the memory to the system doesnt work.
This is the situation with a Kickstart 3.0 Amiga 1200:
In the picture below you can see the previous settings ("RAM Speed: 100nsec", ...), new settings("setxa ramspeed 70", ...), and the state after adding the board's memory. After "setxa addmem", it takes maybe half a second to activate the memory. During this short timespan the Amiga remains usable - e.g. a mouseclick on the workbench. But once the memory has been added, it looks like any memory access fails. That includes (re)focussing the shell-window, clicking an icon. When keeping the shell window active (no workbench click), keyboard input is still possible, but entering a valid command and hitting <Return> crashes the machine.
Behaviour is almost the same with different RAM SIMMs/speeds/cycles, only the type of system crash differs: sometimes screen graphics corruption, sometimes black screen, sometimes Guru Meditation.
With a Kickstart 3.1 (=autoconfiguring) Amiga 1200 the screen stays black on powerup.
