Re: Qubbide Extended drives
Ah, thanks
That makes sense. So we are making the CS lines more granular, but still using the overall select for that I/O area to gate the other signals through the GAL(s)
I was planning on decoding 4, so just need to use 2 of the address lines A4 and A5 then.
Many thanks for the response.

I have GAL equations for Qubbide - not sure which version, but these have the amendment for alternate status register - dated 1998 Jul 07. Looking at the manual an...

Wanted - QL motherboard - non working...
As per the title - I am after an electrically broken motherboard for standard QL. It's more about having a template to work with. It can be missing connectors, components, broken tracks - just need it for the physical dimensions of the original board, happy to pay postage and a small amount of beer ...

Hello from Berkshire...
Ex owner, came across the forum in my searches online for all things QL. I had 3 of these, before selling up. But I have a love of old hardware designs and making my own little mods to them. Currently have several projects on the go - a P112 z80 based system on the build, in an old media server case...
