Hi Guys,
just to add another experience with the VGA problem to the thread.
Yesterday i got my GBS-8200 Ver4.0 and i was able to connect a standard VGA monitor to the QL. The pins were the classic ones RGB,GND and Csync.
The solution works perfect with a German QL issue 7, but no chance with my English Issue 5 one. But i am already aware that this machine has unstable signals, even on the digital site. I am getting only noisy pictures on all outputs from it (time to look for the error).
The VGA converter works with all modes. No chance to test with a Q60.

Latest news: On my issue 5 i added the resistor (1K Ohm), described earlier, in seriell to the C-Sync line and got a stable picture. On the oszillocope i saw a serious defoming of the signal wihout the resistor. I put also 100 Ohn in seriell to the RGB line to protect the ZX8301.
The noisy internal signals of the Issue 5 just causes a very light noise on black areas. But who cares if you now can use a cheap standard mointor. On the picture the monitor is in 1024/768 mode, so the QL picture is strechted a bit in vertical, but that can be adjusted on your demand.
I paid just 30 Euro (inc P&P) in ebay for the adapter.
