I first used a "disassembler" in late 1980, a program that disassembled 8080 machine code into 8080 assembly language. ( it was called "Resource"). I recall my first (comic) "disappointment" was that it didn't somehow regenerate the original labels and comments...!!!

ZESOURCE: Extension of RESOURCE
RESOURCE: disassembler for 8080 programs
by Ward Christensen (312) 849-6279
" RESOURCE commands are inconsistent at best. - RESOURCE is a kludge based on
years of disassembler experience and hacking, and was never "planned" - just
coded sitting at a tube, and modified over 2 years before being contributed to
the CP/M UG (1/80). For example, to kill a symbol: k.label but to kill a
control value: caddr,k and to kill a comment: ;addr, but RESOURCE does the
job like no other I have seen.
N-O-T-E: Pardon the editorial, but I feel hardware without good software is
useless to 99% of us. Most good software has to be paid for. I strongly
support the legitimate purchase of licensed software. I do not regularly use
any programs which I have not purchased. (Yes, I do occasionally "try" one,
but then buy it if I plan on using it). I have been asked by software
businesses to NOT distribute RESOURCE - because of it's ability to produce
good .asm source quickly. But, there are so many disassemblers out, why not a
good, conversational one? Please use it in the spirit in which it was
contributed: to enlarge your understanding of the micro- computer world
around you, and to allow you to customize programs which you legitimately own,
for your own use.

Ward Christensen built what I understand was the first computer bulletin-board system, which he called "CBBS", in Chicago.I became friends with the owner and operator of the second (?) CBBS, called "CBBS-NW", Jim Willing, who lived in Beaverton Oregon in 1980.
