|It seems a little more serious than 'crash' as it locks up MAME entirely, requiring the process to be killed.|

Looks like a timer set to lower PC2 on the 8255 is getting recursively called.
Removing the timer adjust in amstrad_ppi_portb_r() fixes Plotting, although I haven't yet tested other games yet.
Regression version is 0.240, likely the strobe fix to 8255.

|I'm not getting a crash, instead it freezes (not responding), and consumes one cpu at high power. Clicking X twice closes it.|
