If your one of the lucky ones a GBS8220 RGB->VGA converter can capture and convert the whole picture in monitor mode.

Re: QL is 30 Event During 2014

Certainly interested in an event, never been to any retro event before.

Train from Edin->Cambridge is real easy.

Or I could be persuaded to drive and pick upto 3 wayward souls up on route :-)

Re: Super Gold Card + Scart

You were spot on!

Soldered a 330 Ohm inside the SCART plug and its all sorted. I shall email RCS and tell them about the issue and hopefully they can fix that for future purchasers!

Super Gold Card + Scart

Ok this is an odd one. Recently got a SGC from RWAP which seems to be working fine, when using UHF output I see SGC initialization message and can do typical "Hello World". When I use the SCART cable from Retro Computer Shack the QL will not "boot" with the SGC card in. It works ...

I took the value from here

Re: GBS-8220 RGB TO VGA Converter

I have got the GBS-8220 board but I have the same sync problems discussed above. After some investigations, I have discovered that this board is unable to manage the PAL standard video signal with 50Hz vertical sync but only the NTSC 60Hz vertical sync. Odd I use mine successfully with Spectrum +3,...
