[Coco] SuperBoard Progress

[Mark Marlette]

All,

Quick update on the SuperBoard's progress.

We did have some problems with the IDE interface and we spent a great deal 
of time making the hardware faster and testing it. The optimizations did 
not pan out and we research and tested the heck out of it. Currently the 
SuperIDE board, which is going to be on the SuperBoard as an option is in 
it's final prototype turn. We also used this platform to make the 
SuperBoard's Expansion bus. This to was also done on the SuperIDE project. 
So even though the SuperBoard isn't completed a lot of the work is being 
done. The software drivers are being tested and complete also. I have a 
problem in my final prototype on this board and I'm tracking it down. 
Appears to be an equation problem in the CPLD that was cured by a non turbo 
mode burn on the last rev....IE: race condition.... UGHH. I'll have the 36 
channel 10ns logic analyzer hooked up and trace it down and squash that 
bug. Again LOTS of testing.

Pro-Tector+ which resides on the SuperBoard is also in it's final stage. I 
have found one problem in the last turn of the board and still have one 
minor problem. When the machine is turned on it doesn't always reset 
properly. Every line is buffered on the uP socket now.

Once this is done all that will be left is to do the memory interface, 
bi-dir parallel port and the SuperROM hooks which is based upon the FLASH 
that is on the SuperIDE. :)

It looks awesome!!!! Need to get the web page updated to reflect this 
work.....Never enough time...... :)

Take care,
