Nice work! This is the latest version of your own design, I take it?
Just a small evolution, 374 buffers replaced with 574's to make the layout easier. Swapped the 245's around so I can use R/W signal from podule bus rather than having to invert it, saving a GAL pin. Clock pins for the latches are combined saving me another pin on thr GAL, together that made enough room for a 3 bit page latch for the ROM in the GAL, so removed the seperate page latch chip. Still uses the same ZIDEFS software.
Nice bit of rationalisation =D>

I never find any Acorn stuff in the charity shops (nor any retro computer equipment at all, frankly) but I did bag this beauty today for the measily sum of £10 - has to be the bargain of the year, surely?!

I was a bit dusty but in fantastic nick and has cleaned up nicely - the mesh is all intact and the mechanism works. Lovely for the office!
