Re: PCI Express video

Do you want a different OS to be the base of your machine, so you can emulate in software? Maybe what I require is already here. If you boot an RPI as a QL emulator how would you know it was an emulator? I know what you mean, and if you are not into native hardware as a philosophy, the tempting asp...

Re: PCI Express video

In theory and hardware wise it doesn't seem very difficult but I suppose not all the information is readily available for the Express video cards on what instructions they need to write to pixels so the QL position could be translated. PCI Express being "not very difficult" hardware-wise ...

Re: Beyond Super Gold Card

Regarding the speed issue, here's a quote from a recent post in the QTOP benchmark topic: BBQL with Minerva and (non-super) Gold Card: 5.640 Q68: 24.125 (SMSQ/E) Raspberry Pi 3B+ with uqlx and Minerva: about 103 This means that even a Q40 or a potential Q68 running from SRAM or cache (roughly 3 time...

Re: LibVT

Of c(o)urse I know that ncurses is newer than curses, but most ncurses calls are said to be easily portable to the old curses, which exists for C68.

What is the exact point in an ncurses port?

Re: LibVT

Probably stupid question, but did you include "ansicondef.h" in your source?

Ah now I understand. It is my prototype, which has an illuminated switch. ;)
As far as I know, Derek uses switches without illumination.

Re: Designing 3-D cases: vDrive & Q68

When you say the power switch, are you saying the plug on front left? No, the power switch is not on the board (and not even mandatory) but added via external wiring. For the standard Q68 case, it is located over the audio socket at the front panel. If moved elsewhere, the case could be more flat. ...

Re: Designing 3-D cases: vDrive & Q68

That said, I think I'll first try and see if I can create a Q68 case from scratch and give it some QL stylings. Sounds fantastic! I'd be happy to use such a case, especially if it contains two extra holes for QLNET jack sockets at the side, and "Q68" 3D letters like the "QL" let...

Re: Designing 3-D cases: vDrive & Q68

I also had a crazy idea of purchasing an empty QL case and seeing how to fit the Q68 within it. I think there should be enough room and using extenders for all the Q68 ports (even for the SD cards) you could get most QL ports filled. Then print some covers to make the backside panel of the QL confo...

Re: Beyond Super Gold Card

The entirety of my comment comes from one simple fact: the available 68k cores for use in FPGAs that are cycle-accurate and complete enough to run QL operating systems are limited to 68000 implementations, with no instruction or data cache and no 32-bit external accesses. Is there any point in cycl...
