If anyone has a working STUN game around here please let me know. I have
an ADSP board with ADSP time-out error and I'ld like to compare it with 
yours.

  I think I'm on the right track, after I replaced the LS245 buffer that's 
tied to PMD16-19 (failing ram locations suggested problems on this bus)
the symptoms changed.
  Now the ADSP 2100 test nolonger runs (before it said that 9E & 10E were
bad) , now it just waits a while and then says:

 	HIGH BANK MEMORY TIME OUT.

  Question_ Does the self test have to read the roms on ADSP in order to
pass this test, or they only matter in the game?

I do not know what version of ADSP Tests you are using, but in general
there are two modes of ADSP Tests.

	1. Tests that are run by the 68010. All of the ADSP RAM (Program, Data
	   and Sequential Output) can be tested this way. Note that the RAMs 
	   are tested at 68010 bus speeds which are much slower than ADSP-2100 
	   bus speeds. Graphics ROMs are not accessible to the 68010 bus.

	2. Tests that are run by the ADSP-2100. The ADSP Program and Data RAM
	   are tested this way. Note that if the ADSP-2100 Program RAM is bad
	   it might not be able to run the test program. The program is solely
	   in Program RAM; Graphics ROMs do not contain program and do not have
	   to work to run the tests. However; incorrect ROM data is a major 
	   cause of game program crashes, especially when the ROMs are in the
	   wrong socket.


Let me see if I understand this. You replaced a buffer and now nothing works.

  Thanks for the info. I'll keep digging more, and as far as the tests go
it passes all other ADSP tests except for 2100 test.
