S-C Macro Assembler ProDOS

We will begin shipping the ProDOS version of the S-C Macro Assembler in July, so we are now accepting advance orders.  There is more to the ProDOS version than just a change of operating systems.  The new upgrade includes a couple of major new features:

!lm+5
!pp-5
!rm-3
.INB (INclude Blocked) directive -- This works just like .IN, except that only one disk block at a time is overlaid into memory.  Allows assembly of much larger files, with only a minor speed penalty.

.AC  (Ascii Compressed) directive -- Generates compressed strings from a string between delimiters, according to rule tables.  Very complex, but worth the effort if you have a lot of messages and need to save memory.
!lm-5
!rm+3
!pp0

The price of the ProDOS version alone will be $100.  The up- grade from DOS Version 2.0 to ProDOS will be $30.  The upgrade from DOS Version 1.0 or 1.1 to ProDOS will be $50, and will include DOS Version 2.0.  The initial purchase price of the DOS 3.3 and ProDOS versions together will be $120.  These are introductory prices which may well be raised in a few months.


65802's Are Here!

After many months of manufacturing delays, Western Design Center is shipping 65802 and 65816 microprocessors.  We recently received a final production '802, and it's now happily processing away in Bob's oldest Apple II (#219).  You can order the chips from WDC for $95.00.  Call (602) 962-4545.
