Feast of Apple IIe mainboard

Feast of Apple IIe mainboardyjfy

 

Fortunately, I got a piece of Super II, collected some related materials, and dedicated to friends who are interested in Apple IIE.

 

In 1980,Apple IIE's first design project called "Diana". Diana was intended primarily to be an Apple II that had fewer internal components, and would be less expensive to build. The project was later known as "LCA", which stood for "Low Cost Apple". the final code name for the updated Apple II was "Super II", and lasted until its release.

 

The Apple IIe was released in January 1983, the successor to the Apple II Plus. Some of the hardware and software features of the Apple III were borrowed in the design of the Apple IIe. The culmination of these changes led to increased sales and greater market share of both home and small business use.

 

1. Project Evaluation boardSuper II is the Project Evaluation board of the Apple IIe motherboard, which has SK4501-01 and 620-XXXX- numbers. You can see the following pieces of Super II on the Internet.

 

1. 1 Super II NO.4As an upgraded version of Apple II, Super II directly skips the wire wrapped version. The PCB date is 8103 weeks.There are two names on the Super II motherboard, one is Walt Broedner and the other is JOHN MACPHEE.

Walt Broedner at Apple did much of the original hardware planning, and was one of those at Apple who pushed for the upgrade in the first place. To help maintain compatibility with older 40-column software (which often addressed the screen directly for speed), he decided to make 80-columns work by mirroring the older 40 column text screen onto a 1K memory space parallel to it, with the even columns in main memory and the odd columns in this new "auxiliary" memory.

 

No information on JOHN MACPHEE can be found. He still appears on the Apple IIe product evaluation board. He is estimated to be responsible for the design of the program or motherboard.

 

This Super II NO.4 has a sticker with "TESTED DATE 9-29-89" on it, which should mean that it passed the test on September 29, 1989, indicating that it was a sample retained by Apple, only But thirty years later, it was still cleaned out by Apple. I don’t know if Apple still has Super II.

This is Karl Grabe ’s collection, he worked at Apple Computer Ltd in Cork from 1983 to 1998.Karl Grabe used this Super II to test character roms for the Apple IIe in 1983, Apple Cork.

The numbers of Super II NO.4 # and Super II NO.13 are not much different, but the dates of various chips are different.

This is my Rev.A board ("5382"):I think that this Apple IIe was bought in a shop in US. I bought it second hand in 1985 in West-Germany.
