Definitely.
I never had a Spectrum. I think it was one of the earlier Amiga graphics cards and was kind of forgotten about when RTG mania hit in the late 90s.
It looks quite capable, though - ZorroIII and a built-in monitor switcher are excellent features. I'm very tempted to get one for one of my secondary machines.
The built in pass through was one of the things I loved about the spectrum. The fact that it supported native screen mode pass through on the card without needing to buy the extra component was very nice.
I had one on my A3000 and it was nice being able to switch between native and RTG screen modes automatically without needing to use a monitor switch box.
I replaced my spectrum with a CV64-3d. While the CV64-3d was a faster card and had an 'add-on' pass through option, I could never find out 100% from a reliable source if it would work in my A3000T or not :-?
I am mighty tempted to get the 040/40 on GVP's website for my A3000T to replace the A3640 currently in it.
