CFFA Logic version 1.3 CPLD has timing problem... v1.4 in testing

[Rich <rich@dreherNOSPAM.net>]

To all CFFA users,

As many of you know the current version of logic in the CPLD shipping is 
v1.3. This was an update from v1.2 that allowed my card to work in the 
Apple II+ and IIe. It also was suppose to improve overall timing 
margins.

Recently, enough customers are having problems with larger CF cards that 
I decided to investigate a little further. I bought a 256MB SanDisk CF 
card and found that it didn't work at all. To my embarrassment it 
appears that in making v1.3 I messed up the timing in other areas. 
Specifically the timing of the latch operation that latches the high 
byte during a read cycle from the ATA device so the Apple can then read 
the high byte. NOTE: v1.2 CPLD does not have this timing problem.

So after more carefully looking at the timing, several key changes have 
been made. These changes will become v1.4 CPLD. After more testing, and
hopefully some beta testing by others, I will let everyone know.

The good news is that now all of the SanDisk and Lexar cards I have all 
appear to work fine. The Lexar cards have never worked for me before.

To get this update out to customers, I think I am going to offer two 
options,

A) Send me your CPLD and I will reprogram it and send it back. No 
charge.

B) I will send you a new CPLD at no charge, and you send back your old 
one.

The customer pays the shipping to get his chips to me and I will pay the 
shipping to send the return chips.

Thanks,
Rich Dreher
