Even if this thing ends up as an '040 accel, if it offers all the goodies like RAM expansion, USB, network, etc. that it promises to - it will be an absolute godsend for 3000/4000 owners.
Just do the math - how much have you guys with real nice 3000/4000 systems with all the more modern bells and whistles invested on little crap like USB cards, network cards, accels, gfx cards? Thousands, over the years.
I got rid of my A4000 back in the day because I didn't feel like shelling out $250 for an Ethernet card to get it on the modern net. I bought a PC that had onboard ethernet, great audio, great video, high speed expandable ram, etc.
I wish I had something like this Ultimate PPC card back then - if it's priced fairly I may even build myself up another legacy Amiga. Hope it sees the light of day.
