Re: Q68 Emulate original QL Keyboard

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...

Re: Q68 Emulate original QL Keyboard

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...

Re: Q68 Emulate original QL Keyboard

(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.

Re: Q68 Emulate original QL Keyboard

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...

Re: Q68 Emulate original QL Keyboard

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 ...

Re: Q68 Emulate original QL Keyboard

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 ...

Re: Q68 Emulate original QL Keyboard

BREAKING NEWS : I have tested Pudge with the just released v1.6 of Minerva4Q68 and as far I can see it works now, except for the sound of course. I have added the SLUG command which can be used to slow down the Q68 (0 = full speed, 255 = slows down to a crawl; 128 will be about original QL speed). ...

Re: Q68 Emulate original QL Keyboard

I would try it in Q-emuLator with both Sinclair and Minerva, to see if is a Minerva issue in general, or specific to Q68. Most games use the keyrow IPC QDOS trap. On Sinclair ROMs, the trap works fine when the rest of the OS is halted or disabled. Yes, but this depends on the IPC hardware being emu...

Re: Q68 Emulate original QL Keyboard

I've recently been playing around with pre-historic QL games etc but using my Q68. I've been booting it with Jan's Minerva mod for the Q68 (here: https://github.com/janbredenbeek/Minerva4Q68) and in conjunction with Martin's MDI microdrive device driver I can get an original cart assigned as mdv1_ ...
