I see the Mega ST ET4000 Hack -- here's the updated URL
It's a pretty impressive mod -- it's actually not a VME Mod but something
that connects the ET4000 to a plain ST.. (so it could technically be wired
into a regular 520/1040ST too).
Here is a VME to iSA adapter intended for MEga STE/TT -
I used to also have an ET4000 - my first 'fast' graphics card for DOS.
Would run up to a 16 mhz ISA Bus (20 mhz with artifacting)...
