Hi.

The original first release of MyIDE cart only used:

A0, A1, A2
D0..D7
RW
O2
IO (CCTL)
+5v and GND

When I connect all these wires to the internals of the Atari, and a modern MyIDE Flash cartridge it seems not to work.

When I connect all these wires to the original non-flash based, Mr. Atari MyIDE it works fine.

When I look at the modern cart I see almost all cart connections points are used. Does this mean these carts do also use the other Address lines? Also for IDE?

Thanks for any help
M.

I guess the GAL-logic uses A0-A13 to select D50x window for CCTL access to the IDE-module.

In the cartridge version (home built), part of the wiring instructions say that the trace to pin A should be cut. Would this have anything to do with the problems you are having in that possibly the MyIDE software is getting overwritten?
Mind you, this is just a thought.

Hi 8-bit,

Thanks for your reply; no it is probably what Mr. Atari wrote. Pin A = RD4. That has something to do with the Atari 'thinking' there is a cartridge installed, and the reserved/dedicated RAM for cart is preserved/used.

With my wiring the MyIDE was not working at all, so probably I need to use all the Address lines and not only A0..A2
