The hardware reset by magic word access to $1C024 resets both the CPU and all peripherals except the CP2200. I am curious whether this does preserve the 68000 registers or not. If not, it won't be possible to do a full hardware reset with CALL 390 because it expects a magic word in register A5 and ...

Just a quick question. If I start Minerva4Q68 from SMSQ/E with LRESPR. Once Minerva has started, Can I safely mount QXL.WIN container files in Minerva4Q68, that were mounted by SMSQ/E beforehand. i.e. When Minerva4Q68 starts, is SMSQ/E completely gone. And any open files are closed. You should clos...

In v1.6, I've added a 'sf q68_reset' instruction which should reset the Q68 hardware. This seems to cause an immediate lock-up on Mark's Q68 (on my Q68 it seems to do nothing, even when POKEd from BASIC). He could fix it by adding a 2-second delay afterwards, however his Q68 locked up later on (aft...

Hi Peter, They surfaced when Martyn tests his QLNET driver. Unfortunately they are so rare that I can not even reproduce them myself. I can't say if there is a connection to your problem or not - I simply have no time to dig into https://github.com/janbredenbeek/Minerva4Q68/issues/1 at this time. Ma...

(BTW, I have been in a long conversation with Mark Swift about the 'freeze' problems with firmware 1.05 and keyboard interrupts. Up to now still not resolved. See https://github.com/janbredenbeek/Minerva4Q68/issues/1 ). No time to have a closer look at the moment, but Martyn made me aware of an oth...

Technically no problem, but I didn't want to drill an extra hole into the case for the extra jack and I didn't use the sound feature anyway, at that time.

Good luck. How does QIMSI replace QLNET for you? By SERNET? Yes, with the new Minerva SER driver I get about 8Kbytes/second when sending from QIMSI to Q68. The other way round is slower but works when I lower the baud rate to 57600. (BTW, I have been in a long conversation with Mark Swift about the...

I just read that SMSQ/E attempts to emulate it but I don't know if that's limited to only the BEEP command or the IPC trap as well It works even with games like Spook or Cuthbert, Tony Tebby implemented it for Q40/Q60 and I think he did quite a good job. From the source I gather that the smsq.hdop ...

Great job! I see that the incompatibility with my mouse driver is now also solved. With the KEYROW dependency on interrupts gone, Minerva for Q68 is now getting ahead of SMSQ/E when it comes to backward compatibility. Well, we could even emulate the IPC sound trap through SSSS though this won't be ...
