Attached are two disk images with Allen Ashley's Program Development
System -- "PDS". Allen has given his permission to post these images
to your website. I have scanned the user's manual which is also
attached.

PDS-SDEN.NSI -- single density PDS disk image (earlier version)
PDS-DDEN.NSI -- double density PDS disk image

PDS will run on Northstar Dos or Micro Complex Dos and includes the
following modules:

ASMB -- combination assembler/editor
MAKRO -- macro assembler
LONGLABL -- macro assembler allowing 10 character symbol names
EDIT -- text editor for stand alone source development
DEBUG -- debug monitor and disassembler
LINKED -- linkage editor
KWIK -- relocating loader

PDS uses the Intel mnemonics including a Z-80 superset, but is written
entirely in 8080 code and will run on an 8080, 8085, or Z-80
processor.
