Hi QuikSanz
don't worry about GVP products, QuikSanz :-)
I'm still using a GVP-TBCPus card (one of my best buy EVER) from 10 years without problems.
Quite all the video signal (exept the YUV one) pass through those card in my video gears.
GVP anf P5, has been the best cards in the Amiga market for years.
The only problem, was (and still) theese "custom" SIMMs for the CPU cards and . . .GRRRR!!!! the custom VRAM of my TBC+ card (1 MB-30 ns, 68 pins payed 9 years ago, 220 EUR (=Lire.450000 from USA to here in Italy)
By the way . . .the first VRAM delivered from USA was defective and GVP has replaced it without any problem . . . great Company :-) (thanks to my friend Casonato-Logica too)
Ciao
