New Cross Assemblers Available

We have recently added three new cross assemblers to the S-C Macro family.

     Intel Z-8...................$32.50
     General Instruments 1650....$50.00
     General Instruments 1670....$50.00

Unlike previous cross assemblers, which were based on Version 1.0 of the S-C Macro Assembler, these are based on Version 1.1.  This means 80-column support for the Videx, STB-80, and Apple //e-//c 80-column, as well as standard 40-column.  It also adds certain directives and fixes some problems which were in version 1.0.

We have also been hard at work generating Version 2.0 of the S-C Macro Assembler.  It will be ready soon, complete with a brand new manual.  It will support all the new opcodes and address modes of the 65C02, 65802, and 65816 processors.  Owners of older versions of the S-C Assemblers will be able to upgrade for a very reasonable fee.
