CAPTURING A ROM IMAGE FROM A TRUMP CARD

by Massimo Raffaele


Here's what I did:

- I saved on QL floppy the first half of the whole addressable QL memory: SBYTES FLP1_global1,0,524288
- I transferred the global1 file to the PC
- I saved on QL floppy the second half of the whole addressable QL memory: SBYTES FLP1_global2,524288,524288
- I transferred the global2 file to the PC
- on the PC, I merged (binary method, not text) the two halves: copy /b global1+global2 global.bin (obtaining a "global.bin" file with the exact size of 1 MB)
- I loaded the "global.bin" file into an editor (UltraEdit), searched for the key word "trump" and... YEAH!  There it was!


The "strange" fact is that the Trump Card ROM appears 3 times among the whole 1 MB area. Precisely at these addresses:
$10000 (65536) - I/O Expansion zone
$77a40 (490048) - RAM Expansion zone
$df480 (914560) - I/O Expansion zone

I then extracted the three 32KB "pieces" from the global.bin file and compared them byte-by-byte (with UltraCompare).
Result: they are absolutely identical. So I can consider the dump to be 100% correct.
