- allthough both Cards have clearly different Layouts both Cards
operate the
CPU at 6 Mhz and both Cards are supplied with on 64
KByte RAM
"onboard".Taking a closer look to the schematics of the
Cards discover
that the both are nearly identical - so for that reason
at the Disk-Section
only the Disks from ALS have been uploaded due to the
fact that thay
operate on both cards andthey offer some additionel
tools like the
harddisk.support.
In September 1985 the german magazine published a
DoItYourself project
that enabled the Users to make a 68008 CPU card for the Apple
II series.
In the following months there had been few adds published to
optimize
the card and thereafter there were several program-codes
published how
to use the card. The card is able also to run with CPM and to
use 68000-
native code.
remark: at the moment the pages
here still are in the native german language,
but i plan to translate the entire text within the next 2
months......
and within that period i will also search for the codelistings
and
software within my archives and bring up both here too.....
unfortunatly the magazin mc was discontinued in early 2002...
probably similar
to the development in germany also in other countries the community
of kids
that still used the APPLE II fadded away due to the fact that the
PC´s based on
the Intel-CPUs dominated the market...
Remark: if you
intend to etch the pcb by yourself it is recomended to use the
printout of the german PDF-file - it has better resolution.
was one of the most popular CPU Cards for the Apple II
Series.
Allthough the card was rather expensive the card was
remarkable
to the fact that MS-DOS Programs did run on that card faster
than
on the XT and AT moidells of those days. AE offered a
"plug-on"
"piggy-back" module to be pluged on the main card and equiped
it
with additional 1 MByte RAM and therefor pushed the limits of
the
card ahead to a point that AT Models could only reach with
additional
RAM cards pluged in. (

the "Rademacher 942" from the german company Rademacher was in
in former days one of the most common PCB´s
for experimental use and
prototyping. The card cost in former days
about $ 16 USD - but in 1998
the company stoped the production of this
card. The card had at the top
border a length of 17,8 centimeter. In very
rare occasions such cards are
offered at ebay and it is a good idea to
keep ebay under survilance for
these rare occasions when this cards are
offered - at least if you intend
to develop own hardware for your Apple II.

The second Alternative is to make some boards yourself at least
if you intend
to develop own hardware for your Apple II.
