Steve, you said you started to reverse-engineer RESEQ.100, I just
noticed there is assembly source and some discussion between the author
James Yi and Phil Wheeler about it in M100SIG
100 version

The assembler for Yi's original RESEQ.200 appears to be this? Maybe? It
has his name in it. (There is also an ADSM.100 in Lib-08 but RESEQ.100
doesn't appear to use it.)

Lib-08 ASSMBL.CAT says that the hex files are installed with HXFER

RESEQ.100 says it's in Custom Software assembler format. I don't know
what that is, but I did see there is a util to convert from Custom
Software format to Polar Engineering format. Don't know what that is either.
"
ASMCNV.BA [71706,334] 20-Dec-85 1630
Source file convertor for assembly files, converts from form used by
Custom Software to form used by Polar Engineering on model 100 and 200.
Changes HL,DE,BC,AF register notation to H,D,B,PSW notation and
converts
DM macro to DB with a character string.

I don't expect you need to actually use the original assembler that the
source was written for, especially since it would mean working ON the
100. I'm just putting everything related together for completeness and
reference. Mostly I just thought the original source and the discussion
might be useful.
