@exxos - I am sure I can fit another chip on that board somehow However I think we now have to task of unpicking our conversations as to how we were going to get this thing to work.
Well the hack jobs I did worked, so if its doesn't work, its your PCB

Got it to boot with from the firmware @exxos was using on the V3 - 1508 mod
Now to start with the RTC first to see if I can get that working.
Have been working through the board all day and have finally got the RTC and Flash functions working. We have found a few oddities along the way for example the RTC chip was initially had got itself into an always busy state and had to prod it to make it think it was not so it could be initialised. We working on ironing out the software and once we have the RTC and Flash areas solid we will start on the ALT-RAM.
Any how the clock functions work and am able to program and boot to one of 5 banks, one being the motherboard ROM, and then the 4x Flash banks. I'll do a video later on the programming and booting to each bank.
In the meantime here is a really wobbly video of the board programming a bank. Lets see if you can spot when the flash is being programmed

Yeah hurry up @Icky keep poor @exxos busy during his lockdown. Hes already crazy and we don't want him getting worse / better. (Delete as appropriate)
I could update the software myself, but well, its tea-time, and icky may have sent it by then anyways.. i'm willing to take the chance...
