Great to hear your success,
This is not the first time I have seen uBee512 not emulating a hardware deficiency, I have seen several examples over the years.
I have not been able to find a logical reason for the upper bank switching to have been left off this board design. The only thing I can speculate, is that the designers wanted to give locations of ROM A,B & C (IC5, 10 & 15) the ability to run mask ROMs 2564's and also 2532's / 2732's which therefore requires the +5V on Pin 26 (PIN 24 in the case of the XX32's).
Yes I can see the Command menu pic regardless of my logged in status.
They are both .png images, but the only thing I can see is that the Command menu pic is attached as a thumbnail and the rom_c is a full image attachment. However as I'm not fluent in HTML script I could be reading it wrong.
