The ones at http://mdfs.net/tube/6502 ? That's odd, as the source
code is correct, and I remember reading the ROMs directly. I must
have inadvertantly replaced the images with ones saved from a live

There are only three differences between the external CoPro ROM and
the internal CoPro ROM:
 
Startup banner: Acorn TUBE 6502 64K vs Acorn TUBE 65C102 Co-Processor
Help message 6502 TUBE 1.10 vs 65C102 TUBE 1.10
OSWORD table for OSWORD 5, 2-byte address sent vs 4-byte address
