Hi Ewan,
Yes, when I did my initial attempt I didn't realise the main board needed the mods. Once I realised I dug out the Hardware Notebook (I now have a printout as I keep referring to it) and converted it. It worked fine for about a week then stopped (Just before I was due to take it to a local retro meet, no less)
I also converted it back to test if the main board had failed or the core board. (It worked fine with the PC85 core board)
I then converted it again back to DRAM for the ongoing testing. This time I did it a lot neater too. :-)
BTW, if it's causing confusion, the BASICA+B ROM is sitting in the DRAM core board. A suggestion from Ernest.
Cheers!
