I guess I was using a prior version, but I could never get it to work. Thanks for the posting the vid. Could you also post or link to the ROM image.

I will have to give that a closer look. I just finished 6 sets of Sys 3-7 boards and used Leon's test ROMS along with some of Hans Hasse's diagnostic tools.

Have a firepower MPU coming in a few days, will look forward to giving it a try!

I was going to give this a try on a Sys7 board I'm troubleshooting but I'm a bit confused by this in the document:

"Only for level 7 boards: Make the following jumper's W23 (typical setting W22), W12 (typical setting W11), W 9 (typical setting W10)."

Can some please explain what exactly these are getting jumped too?

Thanks

Digging this one up as I'm going through a really hard to diagnose board right now.

The jumper settings shown are done to change the IC17 to read from a 2716 chip instead of a 2532, and moves the ROM address for IC20.

I haven't had a chance to test it yet, but you could probably just double it up on a 2532 and leave the jumpers alone. Will report back in the future on this.

Ok, I can confirm. You do NOT need to change the jumpers on a System 7 board to run this rom. You can simply double it up on a 2532, and it will run just fine.

Also, John is correct that you can use one of my LED bar boards on the display strobe header at 1J7 for this test as well.
