Default GoMMC and Sidewise

Hihi

I've been using the excellent GoMMC for a bit and wanting to have more
ROMs I bought the ACPL Sidewise rom interface with the two 8K RAM
chips from eBay

I've seen from some posts that people have successfully used both but
not how to actually achieve this, I'm not actually bothered about the
RAM bank on the ACPL since I'll be able to blow ROMs containing what I
need

However, atm I'm getting results like this:

which after talking to the author it seems is because reads/writes to
the static RAM on the GoMMC board are being intercepted by the ACPL

Can anyone tell me how I can get it working? losing the sideways RAM
would be unimportant, it's the ROM slots I need it for so I can install
patched filesystems and so on

Thanks

Default Making ATPL Sidewise work with GoMMC

Hihi

Never mind, worked it out, here's the info if it's useful to anyone
else:

There are two routes, one if you want the ATPL sidewise RAM and one if
you
don't.

Route 1: Switchable sideways RAM/GoMMC

If you want it, it's very simple, fit a switch to EI and EO, short
when you want to use GoMMC, open when you want to write data to the
Sidewise RAM bank (which you'd better do from floppy since you won't
be using GoMMC while it's open)

(although you could load a file into memory from GoMMC then move the
switch I suppose)

Route 2: make Socket 15A ROM (15B is then unused) and have no sideways
RAM

Bridge EI and EO
Cut S4
Bridge S5
Cut S8 East
Bridge S8 West

Remove the two RAM chips, put one in your Canon X-07 :-)

this will disable the RAM writes on the board and give you a 12 socket
Sideways ROM board essentially.
