Re: QL Core on Spectrum Next KS3

Hi Richard

XChange certainly works on the QL-Core without issues.

You'll want to configure it's default directories to use 'win1_' instead of MDV or FLP, or possibly to use something like PTH or SUB to get QDOS to redirect MDV/FLP to a chosen subdirectory on WIN1_<somepath>

As for printing, the ...

'Proclivity'!

That must win our Word of the Day award, Dave!

Those darn 2-tone CPU sockets... How many have I trashed!

Re: My current QL accelerator project

Morning Mark!

More great progress - well done!

Ok, so that apparent VPA bus cycle is not really a bus cycle, but a workaround for not having a dedicated 'Auto Vector' Interrupt Acknowledge signal.

All interrupts on the QL are thus hardwired to generate the Auto Vector approach to interrupts. In ...

Re: QubATA v3.11.. - can't seem to re-partition my DOM drive...

Hi Derek

Yes, I provide power via a separate 2-pin 5v connector (though it could take power from Pin-20 as well.)

Is a 'PQI 128MB' - cheap, if I remember correctly, so probably not quite to standard anyway.

What is perplexing is that it formatted and was accessible under QubIDE 2.01, but not once ...

Re: QubATA v3.11.. - can't seem to re-partition my DOM drive...

Thank you Derek :-)

Your SB program appears functionally similar to the process I followed.

I suspect something awry with my DOM - I have another to test - after I return from the family holiday in August :-)

Warm regards,
Martyn.

Re: My current QL accelerator project

Hi Will!

I've been following your progress with great interest :-)

You can ignore interrupts from the 8048/IPC, but should expect IPL1 to go active on each 50Hz interrupt - but only after you see the Minerva logo appear (if Minerva installed), or else once the traditional F1/F2 prompt is drawn ...

QubATA v3.11.. - can't seem to re-partition my DOM drive...

Hi everyone (and esp. Alain Haoui - if you're here!)

I've finally gotten my Aurora+SGC system built and started to explore using the QubIDE (original board - but with the v2 GALs "1a/2a") expansion-card.

I had successfully attached and formatted a 128MB DOM (single partition) with the QubIDE v2.01 ...

Re: Bare microdrive units.

Hi Dave!

I LOVE your initiative here - if there is anything I can do to assist in developing/testing your improved MDV headboard design, please let me know.

I may have a couple of spare MDV units and I also have a couple of NoS MDV ULAs, ready to replace failed units.

If it proves easier, I have ...
