Re: My First Sinclair QL

Hi POLKa That lead from Retro Computer Shack works because it also connects the Composite PAL signal from the QL (pin-1) to the SCART Blanking input (pin-16) - which doubles-up to select between CompVideo (0-0.4V) and RGB (1V to 3V) on most TVs. The Comp-PAL signal from the QL, whilst fluctuating, i...

Re: QOMBI

My own first experience of PC gaming was a terrific puzzle game called The Incredible Machine - see here on ''My Abandonware":

I'd love to see something like this on the QL!

Nah - just switch to SUPERVISOR mode, at least anything really important could still catch Dave's attention :-)

Hi Dave!

That'd do nicely!

(I'll reserve judgement on the other topics since discussed here - beyond my pay-grade to comment!)

Re: Announcing availability of a QLNET driver for the Q68 (ND-Q68)

Terrific, Dave! I couldn't spot your 'mistake', but take your word for it! One thought - those 2mil pitch headers are more awkward to find connecting cables for than the more common 2.54mil pitch - could it work to include the 2mil (to connect to the Q68) and a 2.54mil for the pass-through connector?

Sounds good to me, Dave. But then, I'm just the SW guy :-)

Re: Announcing availability of a QLNET driver for the Q68 (ND-Q68)

Good evening afx and Francois If you are hesitant to make the HW mod yourselves, I believe that Derek Stewart from whom you purchased your Q68 HW is currently researching some viable solutions and plans to offer a modification service in due course. I will be posting some guidance plus photos from m...

Re: Announcing availability of a QLNET driver for the Q68 (ND-Q68)

Hi Pr0f The propeller has several timers on board plus access to the cpu clock timer. Also useful is a wait on I/O port which could be used to trap for the start of a sequence on the network :-) I believe the Inteface 1 used something similar. So with the timing routines it should be possible to rea...

Re: Announcing availability of a QLNET driver for the Q68 (ND-Q68)

Hi Pr0f! Awesome work - I may steal the timer idea to get QL networking driver written for the propeller if you don't mind? It 'aint stealing when it's given freely! In the provided source-code, you'll find a bunch of 'timer-primitives' fully commented towards the end of 'dd_nd_q68_phys_asm' - just ...

Hi Dilwyn! Well done Martyn. I'll be pleased to add it when you're ready. As soon as you like, thank you! The zip-file attachment to the original post is all that is needed, perhaps with a 2-liner comment: "ND-Q68 is a new driver for the Q68 to allow networking with QL-compatible devices over t...
