I try to inform all 4 major venues (this list, the English forum, the
German forum and Facebook), which is a bit of a pain but they all have
distinct groups of users.

But while I do get the rejection of Facebook I encourage joining at
least the English forum, it is a very lively place (between 5 to 30
posts a day I would guess. If that is too much, the forum is split
into hardware/software/etc. so easy to filter for one's taste) and
unlike Facebook it is exclusively operated by QL enthusiasts.

I uses an RSS reader to read the forum, so I get to see new posts when
they arrive, just like in an eMail list, and can then decide to chime
in or not. This way reading it is very comfortable without having to
manually poll the site for changes, which in the past was my biggest
grievance with web forums.

That is was designed exclusively with the QL in mind and it just
works. If you already have a converter that works for you, you
probably don't need QL-VGA.

Not software. It is simply a hardware description, and the result is
pure hardware, i.e. flipflops, gates, wires. You can as well describe he
same hardware in a schematic rather than text.

It is important to understand that no emulation is involved and there is
no difference to other logic chips, except that an FPGA can be
re-configured. Like GALs, just more complex.

Thanks John. I get that it's a software description of some hardware. This is 
the first time I've come across it. I might spend some time looking into it - 
if/when MrsD allows - just to satisfy my own curiosity. Not that I'll be doing 
any hardware design though.

 Yes , think of it of a high level and standardised method of describing the 
configuration of your FPGA hardware rather than a program for it to execute.For 
example I could define  logic blocks to act as flipflops and attach the input 
to one pin and the out put to another they don't need to  interact with each 
other to perform this so the config maybe sequential once loaded in to the FPGA 
 the resultant Logic config works in parallel or as parallel as you wish to 
design for!JA

Yes, it's a bit of a pity that the discussions tend to get split up
nowadays. The most active thread for QL-VGA is actually the Facebook
one this time, with currently 474 members the QL group there has a
different (more wide spread) audience than even the forum.

Well, it's a bit like programming, the difference is just that
basically all lines execute at the same time! If you want something to
execute sequentially you have to implement a state machine.

That's the gist of it. If you have a base clock and base everything
off of that things are pretty clean and work nicely. But if you have
different clocks things get weird very quickly. For example I tried
implementing an Aurora card for the MiSTer FPGA board, but I couldn't
get the pixel clock to change reliably, it only worked like 50% of the
time.

For QL-VGA I use a base clock of 130Mhz, which divides nicely into the
10Mhz QL pixel clock and the 65Mhz VGA pixel clock, so nice and clean.

Debugging is either done by simulating your code on the PC or by
actually compiling a complete logic analyzer INTO your design so it
runs on the same chip next to your own logic :-o You can then read out
your signal data using the JTAG interface. That is pretty cool.

For a pretty simple example the QL-SD code is open source if you want to
see how this looks like: https://www.kilgus.net/soft/qlromext_spi.v
This is so small it compiles to a CPLD chip, which is basically a GAL
on drugs. But the way to code is exactly the same.

I like the design decision to use a widely-available cheap platform.

Seeking for testers? I would jump in with my various QLs and multiple VGA
monitors.

Looking forward to see this thing become available for the QL community.
