DIY Amiga DB23 to VGA (15 pin) adaptor
Hi all,
Did this adaptor the other day, works great...Goal was to make a very cheap adaptor, hence the use of a cut down db25, but still with good signal quality, maybe someone else has use for this info so sharing it here, github here: https://github.com/jbilander/HowTos/...to-vga-adapter

Great work! How much was the cost when you say 'cheap' since I know AmigaKit sell these for under £10.

Thanks, Don't know exactly about cost, I had most parts at home already, just had to get a new db25 and I was all set.

And now you can use normal PAL resolution on VGA or LCD screens with VGA input?? Or is this DBLPAL or EURO36 Screen mode?

I made one of these last week and used a 74LS14 instead of a 74HCT14. Seems to work but I see some jitter. Not sure how critical the choice of logic family is.
