Re: Asymmetric multiprocessing...

How much work would be involved in doing a 'Tube' like the BBC ? There is even an option to have a raspberry pi zero as tube add on, all be it with bespoke code running. Hi, There is a BBC Tube add on card for the Acorn Electron and an interface to add a Rapberry PI as a second processor. I think t...

Re: Asymmetric multiprocessing...

I plan to discontinue the ROM port after Issue 8 as the image can be saved in flash and relocated. I found the connectors to be very difficult to source, and quite expensive at £5/00 a ...

Re: uQLx 2018a

Hi,

Having used tge forked version of UQLX 2018a, which looks a little faster and it seems to run all the software I have.

I added in TK2 223 which gives Level 2 device drivers, hard directories.

I would like the ability to have the second screen enabled, maybe from a command line option.

Re: Asymmetric multiprocessing...

Hi, Is it possible to programme the Miracle Midi Z80 CPU to perform Z80 assembley language programmes other than MIDI interfacing. Maybe this a way to add a co-processor to the QL. I have a working Midi interface to try this out. I will have to look at Phil Borman's extensions which was to connect t...

Re: uQLx 2018a

Hi,

I downloaded the 2018a code and compiled okay on my Linux laptop.

Loaded in the Extended Environment, Qpac2, Turbo Toolkit, Turboptr, Qliberator.

I use QXL.WIN files for storage.

All compilers work as expected.

Re: Asymmetric multiprocessing...

Have you worked out a schematic, or got clear photos of the MIDI board? It sounds like it would be a very interesting thing to see. MIDI has been whispered in my ear more than a few times in the last 3-4 years. Hi Dave, On the Yahoo QL Hardware Gorup, someone posted some QL schematics and layout fi...
