Re: Hello from the SouthWest

Been some improvements in the Z88 OS as well - I have a couple of Z88's - one with a bigger supercap, 512K Flash and 512K RAM internal upgrade - a full Slot 0 :-)

Re: Q68 QoE Ethernet Driver

The perils of writing code for micro controllers ! Using a high level language distances you from the silicon, so keeping an eye on call stacks and so forth is that bit harder. I program a lot with PIC's, but usually resort to assembler (because I like pain :lol: ), and it tends to focus your behavi...

Re: Keyboard Interface problem

I think the fact the ABC Keyboard interface plugs into the ROM socket - confines it to the bottom 64K or memory map - so accessing areas outside is not really possible.

That leaves you with 48K for the OS and 16K for extension ROM (TK2, user ROM, whatever you want in there).

Re: Keyboard Interface problem

most of the Minvera ROM versions are pretty packed, as is toolkit II, so you are unlikey to find the room in a 64K Eprom for the keyboard driver as well.

Re: Sinclair QL2 Prototype replica on eBay

I think the keyboard itself is from an original QL, and just sits in a void within the printed case.

Re: Sinclair QL2 Prototype replica on eBay

It also looks shorter than the original QL case, and probably lacks the opening for the expansion port. All things that could be sorted though...

Re: I hate BREXIT !

Now it's just getting silly - as most of what we see is just oscillations - then surely a quick Helium bath for everyone and we'd be no more...

Re: Sinclair QL2 Prototype replica on eBay

You can just make out an SD slot at the front of the case - in the area of the 'red dome'. I think the case is printed in 3 sections to get the length, and looks to have maybe 3-4 layers.

I'd be interested in the 3d print files for it - but not for that money.

Re: Sinclair QL2 Prototype replica on eBay

the alignment and positioning of the 4 USB ports and the RJ45 scream Raspberry Pi !

So most of what you are paying for is a rather slick looking case.
