Arrgh I'd forgotten about that, but you're right, that was also another great feature.

I always assumed the crash was because the Z80 jumped into machine code in the ROM on the Interface 1, and if any of the edge-connector pins waggled, it started executing rubbish (aka as going into hyper-space) with the microdrive hardware in record mode.
