It's jumpered to 1Mb at the moment. (I'm 1 jumper short but memory size doesn't make any difference)

It's the same TOS I use with H4 build. There were no issues with it.

Its not what I mean, I mean checksum will verify all the ROM address / data lines are connected correctly etc..

A10 and A13 shorted together. These are the 2 measuring lower, 2.4k (common imp) to gnd as well.
I'm hoping if that's fixed it will be back.

@exxos Can you help me with these 2 lines (A10, A13). When is it when they're running close together? To MMU?
thanks
