Feast of Apple
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
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 board
Super 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.4
As 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"
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.
1.2 Super II
This is Karl
’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,
The numbers of
Super II NO.4 # and Super II NO.13 are not much different, but the
dates of various chips are different.
1.3 Super II
apple2history.org, "Dean Nichols for finding such a creation from
the bowels of Apple and sending it" Dean Nichols got it from within
1.4 Super II
is sold by vintagemicros.com website, the number is 84, it seems to
increase the SPEAK function.
As can be seen
from the numbers of these 4 motherboards, Super II has manufactured
about 100 of them.
820-0064-00 is the product evaluation board for Apple IIe, which has
been officially named Apple IIe and also has the number 620-XXXX-.
The PCB date is 8212 weeks and the copyright number of 1982.
820-0064-00 is the product evaluation board for Apple IIe, has been
officially named Apple IIe, and also has the number 620-XXXX-.
It also has an
inscription on the bottom right that reads
/ AURICCHIO / RICE / MACPHEE”.
There are two more names than Super II.
is from JonathanFrance.
This motherboard is from the transwarp
This motherboard and my Super II NO.4
come from nerjembless, the same seller of eBay.
3. Apple IIe
official version of Apple IIe has not been marked with the names of
personnel related to the design and production of the motherboard.3.1
Test boardThis Test board is an OzKFest collection. There are 820-0064-B
and 607-0164- numbers. The test board is handwritten with the number
"081" in the blank space, and the official version seems to have the
date printed here.
4. Apple IIe P.A.L.
4.1 Test board
following is the Apple IIe motherboard sold by eBay seller
econsaints. The PCB date is 8238 weeks, which is the test board. The
numbers above are 820-0073-A and 607-0664-.
5. Apple IIe NTSC version
6. Apple IIe
7. Apple III
IIe appeared a little later than apple III, and its design also
borrowed from Apple III. by the way, look at the mainboard of Apple
7.1 Apple III PROTOTYPE
Kottke was Apple employee number 12 ,Daniel was heavily involved in
building and testing the early versions of the Apple II computer,
and later built the some of the first prototype of the Apple III ─he
owns the firsApple III prototype.
