Re: How best to introduce a timed-delay whilst in Supervisor mode

... And in articulating the original question, it now dawns on me a more fundamental issue in blindly re-coding the 'manual retry' as it appears in the existing NET driver... For as long as we remain in Supervisor mode, the Message Queue Scheduler task won't be running concurrently, so we'll never s...

Re: How best to introduce a timed-delay whilst in Supervisor mode

Thanks Martin and Tobias! Yes, for 1s granularity, the emulation of the IPC timer (where available) would suffice for the overall 25s timeout. However, the 7ms 'pause' between manual attempts to re-try the last NET operation remains an open requirement. In fact, as well as the 7ms pause, the actual ...

How best to introduce a timed-delay whilst in Supervisor mode

Hello gurus! I am researching how best to re-code a software timing loop within the NET device driver that is currently tied to the CPU clock in such a way as to duplicate the intended timing effect in a reliable way inside an emulator such as QPC, QEmuLator, uQLX etc. This is part of the on-going Q...

And just...

Re: Games don't load, RAM issue?

Hi Chr$ I concur - though it does require four times the shipping cost and assumes that you can successfully write to (your) cartridge as formatted by the recipient, but it gives you a bit more control over the likelihood of it working when they get it back :-) More than happy to test out some of yo...

Re: Games don't load, RAM issue?

Hi Chr$! Without meaning to displace the RAM fault idea altogether, I would be inclined to suspect instead the state of the recipient's MDV unit(s). The fact that the larger files appear to fail compared to smaller ones is as likely due to the higher chance of a bit-error across a higher number of s...

Re: QLUB Adapter - Initial Release...

Hi everyone - a short update during my lunch-break... Thanks to Stephan's diligence and determination, we now have the QLUB Adapter running successfully with the GoldCard-equipped QL, with both QPC and uQLx emulators on the PC side! So far then, with the enthusiastic participation of several communi...

Re: QLUB Adapter - Initial Release...

Oops... In my earlier post where I attached the 'nettime_bas' program from the SGC ROM source distribution, turns out that QPC/SBASIC objects to the use of 'loc' as a variable name - clashing with LOCal keyword, I guess. I've updated that post with a revised version ('loc' changed to 'location'). Th...

Re: QLUB Adapter - Initial Release...

Hi again everyone I thought it might be helpful to write a short description for anyone wishing to gain a better understanding about the role of the all-important 'Timing Constants' around which the QLAN NET driver is designed. I plan a more full description in the second article in the 'Networking ...
