Hi tOnyt!

Whilst in principle it should be perfect tly.possinle.to access the I2C bus whilst running a different QDOS version, I suspect that the tight timing loops that are used by the I2C toolkit rely on the primitive routines running in uncontended memory at a fixed or at least consistent ...

Hi t0nyt

I recall reading that the Minerva MKII can only act as Master and that ID clash will therefore be with the RTC/NV-RAM device that is fitted alongside the EEPROM and PAL.

Not sure whether the RTC IC can be configured for another ID, but would imagine so...

Thank you Derek!

I've since received the PIC uC and have programmed them successfully with my humble TL866-CS, so will be wiring them up to connect PS/2 mice via the Atari compatible mice ports on my Aurora and Thor (once I've replaced the 68B02 on my Thor's IO board...)

I'll share my findings ...

Thanks guys!

I've got the PIC arriving shortly so will just need to find a way to program it and try it the converter.

Don't know how I missed the comment on the QXL.WIN site nor Detlef's PS/2 converter design - so thanks for the links!

And how that 'S' snuck-in my original post I can only assume ...

Good morning all!

On both my Thor XVI and my Aurora QL I have QIMI compatible mouse ports and wanted to explore the use of a more modern/available mouse.

As I use PS/2 mice, I was hoping that the Atari ST/Commodore Amiga type mice interface might be usable via a cheap PS/2 to Atari/Amiga Mouse ...

Hi bwinkel!


When putting modified SD card back into vDrive, be sure to do a reset on QL for it to see updated changes.


This instruction is particularly important and, as it happens, applies equally to swapping in/out real MDV cartridges (and possibly even FLP diskettes) and is due to QDOS ...

Yummy!

Hi tonyt!

Adding a switchable 128kb EPROM is relatively straightforward - the most tedious part is accomodating the extra pins (A16 and Vcc) and re-routing the Vcc power pin from (current) pin28 to its new home. The Minerva carrier board already does the heavy-lifting of routing the A15 and CE ...

Hi everyone!

My own experience, now after about 10months of extensive usage of the QL-Core on my (KS2) Next matches tofro's feedback below. Similar on a KS1 clone (N-Go.)

Aside from the clunky FN key mappings, I find the system a very fine platform for my QL work - especially once you add the ...

Hi Jan!


Ever wanted to have command line history in Minerva by just pressing the up/down arrow keys, just as in SMSQ/E? Well, Minerva now has it!


Brill!

On a day to day basis, command-line history is the only thing I really miss when switching from SMSQe to Minnie (I know, sacrilegious to ...
