Makes sense to halt the cpu during refresh. Interesting that PCS0 is connected to INT1.

And now have the Casper 68000 2nd Processor running. The software list bbc_flop_68000 is now supported with this.

Nice work! I'm glad to see the BBC finally hitting its potential in MAME.

Not many more 2nd processors left to add now, and will be enquiring how best to implement the 32016 CPU sometime soon.

Whilst many of these 2nd processors were potentially great for business and educational use, not much software was ever produced specifically for them. And being targeted at businesses meant software was lost rather than being found 20 years later and imaged by home users.

The 6502 2nd Processor can run an enhanced version of Elite, faster and more colours due to having more RAM available for video. Am hoping no-one posts Elite to the Gotta-rum-'em-all thread until I get the video issues fixed to really show this off.
