WTB 3/80 colour framebuffer

Having got my 3/80 up and running, I'm now on the look out
for a colour graphics card. These are a bit tricky to find...

Unfortunately the 3/80 has a totally different layout to the
3/60 so you cant use a framebuffer from the 3/60, which is a
shame because these are reasonably common.

The colour cards which are known 3/80 compatible are:-

501-1443
501-1505

If anyone has one of these let me know (off list). I would
pay up to $300 for a known working colour framebuffer for
a 3/80 - they are pretty rare - but would make it a lot more
usable in my current setup.

Thanks

Ian.
