Title: Budgie rev. A ?
Post by: Jose on May 04, 2007, 08:42:19 PM

Are those rare ? I've always heard that latest rev. A1200 boards were made to take newer chip revisions that never came out (hence the timing problems) but I got a rev. 2b here that has a diferent Budgie then other boards I've seen, wich were rev0.
So could it be that some few boards were actually made with the right chips ?

Nope, not rare.

There were 3 variants that I know of:

Rev A
Rev 0
Rev 1

No idea what the differences between them are.

Here are some examples of date codes taken from the photo's I could find on the net.

Rev A - Week 48 1993
Rev A - Week 05 1994

Rev 0 - Week 52 1992
Rev 0 - Week 06 1993
Rev 0 - Week 10 1993
Rev 0 - Week 11 1994

Rev 1 - Week 50 1995

As well as being 3 revisions, there were at least two variants (-01 and -02) again I have no idea what the difference between the two are.

Judjing by Eyetechs info on they're old site they're all buggy I guess. Maybe we could ask Dave Haynie:)

He probably wouldnt know. Dave Haynie was in a department called SYSTEMS GROUP at commodore. They just "thought stuff up" they rarely implemented anything at silicon level. Just Gate-Arrays.

We need someone from CSG (Commodore Semiconductor Group). I'd love to get my hands on some of the information about the revisions of different chips, bond-out options, packaging.

Trying to find out the differences between Agnus chips is almost impossible.
