Re: vDrive: With MDV sound? I wonder.

I've built the first version of the sound unit today and it does actually work. Cool idea, congratulations! Crazy how far the gap between wishes for QL style hardware is. Ranging from "several generations newer than Q60" down to "simulate 1984 technology - but please with sound"...

Re: Q68 netwrok port hardware

Yes Detlef and others successfully did that at last years German QL meeting.

Re: Development Systems and Created Code (reentrant, ROMable, ...)

Peter said in the above thread: "PDQC can create ROMable code". Well that is correct and (I'm afraid) also wrong. The C-Compiler of PDQC (Lattice as in EJC and Metacomco C Development Kit [MCDK]) can create reentrant and even ROMable code. Therefore you must use the compiler option "...

PDQC can create ROMable code, thats the only reason I use it. I compiled the very first working QL-SD driver (long before Adrian's Qubide derivative and Wolfgang's QLWA version) with PDQC.

Hi François, glad to hear QLNET with the Q68 works for you now, thanks for the update!

Re: EJC (C-Compiler) experiments

What is the point in using this compiler? Why not C68 or QDOS-GCC?

I've been using another ancient compiler called PDQC, but the only reason for that was truely relocatable code generation.

Re: QL-SD

Second that. An unexpanded QL is not much more than a plain 48k Spectrum (measured by the amount of stuff you can do) I actually had a plain 48k Spectrum. Loading programs from tape was a pain. The rubber keyboard was a pain. Text processing with 256 pixels, resulting in 3 pixel width characters wa...

Re: QL-SD

The SD cards you buy now are invariably microSD cards with an adapter anyway, so it makes absolutely no difference. I experienced the practical difference when interchanging cards between Q68 and Q Zero. Often taking the microSD card in and out of the adaptor is quite annyoing compared to just movi...

Re: QL-SD

Let‘s say I can produce it for 15€ total (the central chip alone costs 5-8€), that leaves me with 15€. Minus the income tax I‘m at maybe 8€ „profit“ (note that none of my work is paid at this point). Only very rich persons with over half a million € per year pay such a percentage of income tax in G...

Re: Q68 support thread

Seen from a programmer's view, the main difference between QL-based HW and "other" is the video hardware which needs to be treated differently. Q40/Q60/Q68 all have the original video modes, so they don't need to be treated differently. Just if you use additional features. The fact that s...
