Consists of: 4 Replacement Chips.
Apple P/Ns 342-0304, 342-0305, 342-0265, 342-6503 or 65C02
The Apple //e Enhancement Kit makes the //e more like an Apple //c,
givingit the same ROM level, and fixes some bugs in the 80 column firmware. It
also comes with a new CPU, the 65C02 which has 22 added opcodes, and some bug
fixes over the original, 6502. Most new software packages will require an 'enhanced'
//e and will not run on the original //e.
Consists of 1 Replacement Chip. (Cutting and Soldering Jumpers needed)
Apple P/N 342-0033
The Apple //c 3.5" upgrade lets the //c use a UniDisk 3.5" or SmartPort hard
disk attached to the back of the //c. Most users can get away with a simple ROM
swap and cut/solder modification, some really old //c's require a new motherboard
as well, and this can be done at an authorized Apple dealer free of charge. In
addition to the ability to use the 3.5" drive, other bugs in firmware have been fixed.
Consists of: 1 Replacement Chip
Apple P/N 342-0077-B (NOTE 'B')
The Apple IIgs ROM 01 upgrade is a replacement for the original IIgs
motherboard, it is not for the ROM 03, hence you can NOT 'downgrade' a ROM 03
to a ROM 01. It is not possible. The ROM 01 (or greater) is REQUIRED for ALL GS
System Disk releases greater than 4.0. It fixes and adds some tools to the ROM which
the system software is dependent on.
