Upgrade kit for the A3640 (2 wait states removed)

[SpeedGeek]

A3640 must be 3.1 or 3.2 version?

Too bad this wasn't available a year back when I had 4 of my A3640s redone and upgraded to 3.2.

Nice to see these improvements coming out!

WTF? This A3640 upgrade was first released on EAB 3.5 years ago! It was later moved to Amibay because some idiots on EAB posted negative comments about it. Since then, many people have done this upgrade and have been very pleased with the results.

I guess there is no Amiga forum where you can avoid negative comments from the ignorant, incompetent or resident site trolls... :rolleyes:

First of all, Commodore engineering didn't add the extra wait states to the A3640. They were already incorporated into the "040 Bus Adapter Application" designed by Motorola. This application was intended to serve as a design example for 040 designer's. It was never optimized nor intended to become the "Default" design for 040 cards (Unfortunately, that's exactly what happened).

Since, Commodore engineering was ordered to produce the cheapest possible 040 card, it's very easy to understand why they used the Motorola design with as few modifications as possible.

For you German guys, Mozart was actually one of the first A1K.org members to do this upgrade:
