  |   YER Assembler Doc
  Is there any user documentation for the York Electronics Research assembler available anywhere?

  It seems that we currently don't have it. Jim Hehl might have a copy.
  Why are you interested? If you want to program something for the Plus/4, there are probably better choices available.

  What would the top choices be for assembler development.

  If you want to develop on the Plus/4 itself, I'd say Mega Assembler. If you want to develop on your PC, you could take a look at Plus4IDE: it's basically just a simple front-end that compiles your code with AS65 and launches an emulator.

  I used Ophis assembler under Linux. It is good for small projects.

  Thanks for the responses. Does the Ophis assembler include an emulator as well?

  No, it doesn't look like it. I haven't used it myself, but a quick search reveals that this their homepage: http://hkn.eecs.berkeley.edu/~mcmartin/ophis/
  It's a generic assembler for the 6502 processor, which was used in many systems (Atari 2600, Apple II, and Nintendo Entertainment System, etc).
  Are you planning on developing something?

  Well, I did 6502 programming on Commodore machines years ago. I recently added a Plus/4 to my collection and always saw it as an excellent programmer's system, so... thought I would try to revive old skills.
