Great work, thanks for rescuing this part of history!

Do you have a Greaseweazle? It will increase the chances of you getting anything off those floppies immensely!

For people who still use SCART 12V is also needed to generate the correct signals for TVs to recognize the picture.

(and, if I'm not misremembering, it's also used to generate to correct voltages for serial communication)

Turns out I had a few more SIMMs, although 150ns they're too small. And then I have the biggest, baddest, most MASSIVE SIMM ever too

Just tell me what you want and I'll send them - but I don't have full sets of the 1MB ones

4x 1MB simms 100ns,120ns,150ns.

I have to have the full 4MB set of all the same speed ratings.

These are all SIMMs I have with those speeds if you can't find better matches.

The actual scandoubler part works great. It falls apart when it comes to keeping track of wlthe scanline number, and how many pixels are on each line. Those numbers seem to get noisy or they don't work at all. Very annoying. This makes no sense. I assume you're resetting the lines every VBL? If so ...

Surprising that Gotek has pin 2 as an output. In the spec (and in the world of real floppy drives) it's an input. However, it should work fine modifying the drives we know how to do it on - so this would support real drives too, https://blog.troed.se/2017/01/20/the-tale-of-high-density-atari-mystery/

The one and only coder of the very _first_ fullscreen!
