I'm still trying to figure out this Firepower board.

Blanking will not go high. I've replaced all chips and sockets at IC1, IC18, IC7, and IC23 and all components in the blanking circuit with no change.

Using Leon's test, the board boots and passes memory tests.

I watched the videos using the Siegecraft Solenoid tester with Andre's test chip. I do not get the same results and I need help deciphering what the tester says my board is doing. This is my first attempt at using Andre's chip.

I should add that when the board LEDs cycle on and off prior to pushing the diagnostic button, the blanking shows high on logic probe when LEDs are on..

Any ideas out there from the gurus?

When it flickers really fast with the failure LED is on, that means the test failed. I think that is saying IC13 has failed, but i can't tell for sure without the LEDs labeled. The test happens kind of quick.

Map out the connector header according to Andre's documentation and note what flickers.

Leon's memory test in system 3-7 is not accurate. Only use Leon's test rom to cycle the PIA outputs. Andre's memory test, while not perfect, is far more reliable than Leon's.

How many people use the Andre Rom? Would this LED test result board be useful?

anyone have a good part number for something to PC mountable and able to plug into the KK headers used on the MPU board. I had it in mind board to wire to female plug which then would mate on MPU 1j7.

I use a test rom that can be downloaded at www.smokingcircuit.com (ROM 0) to test memory.. Has always seemed to be accurate.
