[comp.os.cpm] 32-bit Z80 code?

julian@uhccux.uhcc.hawaii.edu (Julian Cowley) (08/12/89)

Does anybody have Z80 assembly code that supports basic
mathematical operations on 32-bit integers?  I would like to use
it in order to calculate 32-bit CRC's (for ZMODEM), so if anybody
has any code that will do *that*, I'd be greatly obliged.

Thanks!

PS. I'm willing to trade for a 16-bit CRC routine in assembly,
if that will help.
