Better 8296 Schematics?

Steve Gray
Anyone got an original of the 8296 schematics they can scan? The zimmers scan is pretty bad. I want to study the video sub-system and memory circuits and a lot of the labelling is very hard to read.

Hi Steve,
maybe these are better to read:
http://www.idealine.info/CBM/PDF/CBM8296_ServiceManual_DinA4_alle.pdf

Are you working on the Colour8296 ?

Re: Better 8296 Schematics? Christian.

Many thanks for that - I'm reviving one at the moment, and the schematics from Zimmers weren't much of a help. Those are MUCH better.
Now, just to brush up on my (non existent) German!

I believe much of the text is at least equivalent to much of the "8296
Supplement", if not outright the same, but the latter can be found in
English: http://6502.org/users/andre/petindex/orig/8296supplement.html.

Hi Christian,

thanks for posting this!

A nice trivia to be found there: the screen seems to be very same as the CBM
700 (CBM-II high profile) version - at least the schematics says "700" in big
letters on it :-)

Hi André,
that's correct only for the 8296-D I think.
The 8296 should use the same CRT as the 8032-SK.

It seems like this link doesn't work anymore.

I have tried to search the net for another copy and also tried to use that URL at archive.org to no avail.

Is it possible to find this file somewhere else?

Did you try the zimmers.net archive?

Cheers

The original question referred to the poor quality of the schematics on zimmers. The missing one was supposed to be of noticeably better quality.

Re: Better 8296 Schematics? You're a saviour, Steve.
I've a "died in storage" 8296 (and a working 8250LP to go with it!) that I've been wanting to get to. This will be invaluable.

Thanks!!

Julian

Thank you Steve so much!

Far better quality than the funet files at zimmers.net.

Re: Better 8296 Schematics?

With the availability of the service manual and ROM images, I thought I
would try to make a parts list for the 8296 (see below). There were a
number of problems, so it probably needs correcting.

4K editor ROMs have a description at $E800-E900, so these are easily
identifiable. This area is not accessible from inside the 8296.

"324242-01" is the same as "324242-10". The service manual says "-01",
"-10" is questionable for a system with only a few variations.

There are two versions of "324243-02B" that are very different. One is a 2K
ASCII ROM. The other is a 4K EURO ROM. The 2K ROM agrees with the description
in the service manual.

"324243-04.bin 2017-05-23 4096" is the same as
"324243-04_editor_din_ue8_8296d.rom 2011-05-22 4096".

"324381.01B" is the same as "324402.01".
