I only have a ZXpand not a plus but mine works fine with both my Memotech Keyboard and ChromaSCART plugged in. Very useful for testing the occasional zeddy that happens along.

Yeah, I have the regular ZXPand too (not a ZXPand+).

And it just seems like it won't move the RAM out of the 8K to 16K area.

Even after I do CONFIG "M=H" and verify with CONFIG "M" if I poke the 8K to 16K region it remembers the value, but if I poke the 40K to 48K region it doesn't. And after I power-off if I do a CONFIG "M" the RAM is back to 8K to 40K. Strange....

The ZXPand seems to work fine otherwise, and my board works fine when I write to it, but I cannot read from it because the ZXPand memory is in the same region (8K to 16K).

Maybe try to write to SirMorris on SellMyRetro. I'm not sure if he follows all threads in this forum.

I can confirm, as Martin recommends, that Sir Morris is best contacted through Sell My Retro.

I have sent a message to SirMorris on sellmyreto on 8/22 but I haven't heard anything back yet.
Does anyone know if there is another way to try to contact him ?

Thanks,
Bean

I believe he's on vacation in the USA, not very active at all electronically.

Can confirm that the good Knight is currently Stateside.
