Test programs on the MPC1000 and 2500 can be run either using a Test OS or a JIG PC Flash ROM. For the 1000 it's JIG PC Flash ROM MPC1K (AJ-771312J) and for the 2500 it's JIG PC Flash ROM MPC2.5K (AJ-771314J)

The Test OS is installed like you would install an OS update on both machines, copy to CF card and it will be written to the Flash ROM of the machine. Once the Test OS is installed, the unit will always start up using the Test OS, until the regular OS is re-installed.

Running the test Program using a JIG PC Flash ROM MPC1K (AJ-771312J)
The PC Flash ROM is used during repair for the testing jig and boot block recovery.
To access the test program on the PC Flash ROM MPC1K follow this procedure:
1. Turn off the MPC1000 and open the unit.
2. Insert the PC Flash MPC1K ROM into J110 on the CPU board.
3. Turn on the MPC1000 to start up the Test OS from the PC Flash ROM.

And it's the same procedure for the 2500 as well

Akai will not issue anyone apart from authorised Akai repair specialists either the Test OS or JIG PC Flash ROM's.

It's a shot in the dark, but JJ might have it. It wouldn't hurt to ask him.

I highly doubt anyone would post something that rare. Having that would enable you to unbrick every 1000/2500.
