Yeah, it was actually my second choice, I probably would have got in trouble with the one I was going to add originally

Just because a lot of people agree on something, doesn't make it a fact. ~exxos ~
People should find solutions to problems, not find problems with solutions.

Re: exxos build
In amongst all the chaos of testing chips on various H4's... #3 seemingly died for no reason which I just investigated.
All the clocks were present but I never saw /AS going low ( or if it did, I did not detect it on my scope). Probing around I saw RESET was switching, but HALT was stuck low all the time. I removed the CPU and HALT started to function correctly again. I noticed a bent pin on the CPU, always one of the corner ones, honestly I seriously hate PLCC packages! But nope, still no boot.
I took the ROM out to make sure it did actually have TOS104 in it.. and after fighting with a iffy PLCC adapter for my programmer, I found them verified TOS was in the lower bank. I also found the ROM also had a bent pin on the corner, and I mention I hate PLCC packages ? But nope, still no boot.
I swapped out the CPU,MMU,GLUE with known working ones but still no joy...But then I noticed something....
Let's see who can see what is wrong, I was frankly amazed by this in more ways than one... I guess us season builders will spot it right off...
Needless to say this board is now booting again now

Re: exxos build
You haven't shorted the necessary pins in the DS1315 socket.
Re: exxos build
That's a point, but that only effects the cartridge port, and in this case there isn't one

Re: exxos build
I will admit I never actually knew what the DS1315 was for.
I'll take another stab at it: You've got your TOS ROM 180° wrong.
Tell us how you feel about PLCC packaging.
