MacpMARS 1.99a, by Alex MacAulay (macaulay@mundil.cs.mu.oz.au)
 
This is an alpha version of MacpMARS. It uses the pMARS 0.8.0 assembler,
simulator, debugger, etc. The interface is still fairly similar to MacpMARS
1.0 (especially the menus), but you can now use the new opcodes (e.g. NOP),
new modes (i.e. *, { and }) and pspace. The current biggest limitation is
that only two warriors are supported (even for the command line dialog
interface). The core display is now in colour. You can also bring up
scrolling text core views (as seen in Redcoder) by option-clicking on a
location in the core.
 
Changes from 1.0 to 1.99a (4/9/95):
- Added colour to core display (which will become useful when there are
  10 warriors in the core).
- Added a scrolling text core viewer (as seen in Redcoder).
- Now uses pMARS 0.8.0.
