Hi Legends,
during corona times i “ported” Dave Cheney’s avr11 PDP11/40 emulator to a Teensy 4 MCU board,
fixed already some bugs in it and added multiple rk drives and a partially working tm emulation.
(space forward/reverse unimplemented)
It runs V6 at about 1 Mips and is completely fine usable with multiple rk and tm drives.
Playing around with V6 i noticed that Shoppa disk and tried to get ncc running, but after some
debugging it looked like it is stuck in some loop which i think is due to possible bugs in
the emulator code.
So the question is, are there programs V6 runnable or rk bootable available which test the CPU
functionality? I already hat a look at some xxdp disk, but the one i found (while they boot)
seem to lack basic cpu tests.
Best regards,
Michael

I wrote an 11/40 emulator too recently and used the diagnostics to
test it (in fact, that's all it has run so far..)
This is my testset: https://github.com/aap/pdp11/blob/master/1140.c#L244
Hope this helps,
aap

Hi Angelo,
i noticed your project recently and found it very interesting, but did not hat the time to look
at it in more detail. Maybe now it’s time to have a more in depth look.
Thanks for reminding me.
Best regards,
Michael
