Apple IIe Enhancement Kit

IIe Enhancement Kit from ReActiveMicro

IIe Enhancement Kit Sticker

The Apple IIe Enhancement Kit by ReActiveMicro is a reproduction of "The Apple //e Enhancement Kit", Apple Part Number(PN): A2M2052. It allows older Apple //e systems to run newer 65C02 software, and display MouseText.

The Kit is composed of 5 items:

• 65C02 CPU, 40 Pin DIP
• "CD" ROM, 28 Pin DIP, 27C64 Series ROM, Apple PN: 342-0304-A
• "EF" ROM, 28 Pin DIP, 27C64 Series ROM, Apple PN: 342-0303-A
• "Video" ROM, 24 Pin, 27C32 Series ROM, USA Text Version, Apple PN: 342-0265-A
• Keyboard "Enhanced Sticker"

Note: Some ROMs do not have the "-A" suffix on them. Apple was very inconsistent with their markings. It's also possible this suffix could denote batch or different manufacture runs produced by Apple.

Only older Apple //e systems require the Enhancement Kit if you wish to run newer software or use MouseText. Newer systems like the Platinum IIe do not require the Enhancement Kit as they would already be Enhanced. Both systems can be easily identified by the user. If your CPU has '65C02' or '65C03' printed on it and the Part Numbers of your ROMs match the numbers listed above, then there is a good chance your //e is already Enhanced and you don't need this Kit. Another good test is to perform a Self Test (Control, Closed-Apple, and Reset). An Enhanced //e displays colored low-res squares on the screen intermittently. An Unenhanced IIe displays animated white and black horizontal bars. See the Testing If Your System Is Or Is Not Enhanced section below for more information.

History

When Henry from ReActiveMicro first returned to the Apple II he found several systems obtained were Unenhanced. This caused several issues with testing and projects. After a little research Henry found that upgrading the //e was quite simple, and created The Apple //e Enhancement Kit for sale to the Apple II Community.

Later in 2015 Henry created the "Enhanced Sticker" for the Kit after several people had inquired about it. This sticker is a very close recreation to the original offered by Apple.

Major Benefits of the Enhancement Kit

The Enhancement Kit has four major benefits:

• Apple //c compatibility: Users can take advantage of newer software developed for the Apple //c.
• Product line consistency: Apple II software can be used interchangeably on both the Apple //e and //c.
• The MouseText character set makes it easy for developers to create software that uses pull-down menus, windows, and icons.
• Easier programming for users:
  • Accepts BASIC commands in both upper and lowercase.
  • Additional instructions in the 65C02 (OP Codes).
  • Mini-assembler for machine language programs.

Note: There is a MouseText difference in the older II Enhanced character sets versus the newer IIGS character set. The "F" and the "G" Mousetext characters are different. On the other II systems they are used to make a "running man" character. On the IIGS they are used for for menu system icon characters. This caused a minor visual issue with some software and BBSes from the era that used MouseTest.

Testing If Your System Is Or Is Not Enhanced

If your CPU has '65C02' or '65C03' printed on it and the Part Numbers of your ROMs match the numbers listed above, then there is a good chance your IIe is already Enhanced and you don't need this Kit. However this is only is only a visual check for the CPU. There is a chance your CPU could be "fake" which mean it could be a 6502 and have had the original part number removed and a new printed on it. This has become an increasing issue in the Retro Community as parts become more scarce. To be certain an OpCode check should be performed using a test program.

Another good way to tell if your system is enhanced is to perform a Self Test (Control, Closed-Apple (Option key), and Reset). An Enhanced //e displays colored low-res squares on the screen intermittently. An Unenhanced IIe displays animated white and black horizontal bars. However this only checks if the ROMs are the enhanced versions and does not test the CPU for being a C02.

Here is a BASIC program which you can enter that will check and identify which CPU you actually have installed. This is the only way to fully check for a C02 CPU installed.

10 PRINT "IDENTIFING THE PROCESSOR:"
20 I = 800
30 READ J: IF J < 0 THEN GOTO 50
40 POKE I,J: I = I + 1: GOTO 30

70 IF CPU = 0 THEN PRINT "6502"
80 IF CPU = 1 THEN PRINT "65C02"
90 IF CPU = 2 THEN PRINT "R65C02"
100 IF CPU = 3 THEN PRINT "65802/816"

Video ROMs

Several Video ROM options were offered by Apple to fit their markets. "USA" English however was the most common. The early Apple II and II+ did not use a PROM, but a 2513 Character ROM widely used in a lot of ASCII terminals from the era. 27-series PROM support which allowed for a custom character set and lowercase wasn't until later "Rev. 7" motherboards.

  ReActiveText
  Custom creation by Henry from ReActiveMicro

The ReActiveText character set more closely resembles that of an IBM 286 PC clone computer with AMI BIOS, and has an Apple cursor instead of a "grid" character. Henry created this custom ROM back in 1989. An avid BBSer, he was frustrated that there was a difference in MouseText character sets between the Apple //e and IIGS. Most of the MouseText BBSes were written for the IIGS and didn't "look" right on the //e. Henry, sensing an opportunity to help the Apple II Community, set out to edit and "fix" the //e's MouseText character set. Once completed, he also edited the letter characters to be more pleasing to the eye. The Apple //e and //c has never looked so good!

The PigFont ROM: Quote from Kevin Lightner - "The ROM was originally developed for a BBS called the Pig Sty. It was a very private board inhabited by some of the top crackers and pirates of the day (early to mid 1980's). The Pig Sty was headed by Mort Goodman in Orange California and was limited to something like 30 members. Mort was a book binder by trade, but a pirate by hobby. He'd not only copy the disks, he'd copy the manuals, bind them, etc. The Pig Font was made by one of the members (The Freeze) if I recall, as a gift for Mort. There were also various knockoffs of the original PigFont."

Note: The PigFont ROM is displayed backwards. This is because the II+ is not "reversed" like the //e, //c is and the program used to make the character images always reverses for Apple II mode.

Note: The Euro ROMs are a larger size and contain two character sets. This is due to a "switch" option on the Euro IIe. Under the keyboard end of the case is a small switch that allows the user to select between the two character set in the ROM.

For convenience we have created //e versions (2732 ROM) of the ROMs listed above. This will allow the use of the Euro ROM in a //e, //c, //c+, however the ROM is not "switchable" as it is in a Euro IIe. Once installed it will be that character set until the ROM is physically removed and changed for something else. See the "Single" folder under the "Dual-Euro" ROM folder.

• We created //e, //c versions of the Euro ROMs which can be found here:

  ReActiveMicro Server

We also sell custom Euro ROMs with any combination of the above images, or ones you send us.

You can make or edit your own ROMs using Omnivore by Rob McMullen. Big thanks to Rob for his help in making this page possible!
