TI-74 Disassembler

An active disassembler that'll run on the '74.

Rename it "DZM.PGM" and load with ' OLD "100.DZM.PGM" '.

I'm having trouble the with attachment process so the next
post will have instructions for use.

All entries are Hex.

Pressing the up-arrow key will cause a BR, CALL, JMP,
DJNZ, or BTXXX instruction to jump to the call or branch
address contained in the instruction.

Pressing "up-arrow" on other instructions should have no
effect.

In JMPs, DJNZs, & BTXXX instructions, the offset byte is
decoded, and the pgm address it points to is appended as
a comment to the opcode display string.

Comments/OP$ which run off the 31 char screen can be
seen by pressing the right-arrow key.

Pressing the left-arrow key returns the 1st 31 char screen.

A work in progress. Suggest, bitch, or flame away.

Bugfix - BR, CALL, Jumps, DJNZ, BTJXXs now work properly.

Thanks, Jack!

Bugfix (typo).

Appreciate hearing about any defects found...

thanks, Jack

Another Bugfix... Change extension to .PGM.

Jack

Added ROM call support...

Thanks for developing this one, Jack!

Glad it's of some use. There's also a loadable sub-pgm version,
if anyone's interested.
