I'll take a look at that when I have time. I'm still working on porting 
the B5500 emulator from Javascript, but there's so many odd peripherals 
in there (i.e. things that looked entirely sensible in 1960, like 
head-per-track discs) not to mention opcodes that change several 
registers in peculiar ways that I'd be surprised if they were directly 
compatible.
