It's the newer Escom version of the A4000T. I love it!
The Quickpak 060 is a fantastic board. Many people don't realise it's
so good. It was designed by GVP and is built with quality that Phase5
never dreamed of. (so far I have seen a MK3 and a CSPPC go bad
this month alone!) It's also the fastest 060 thanks to it's
supporting EDO RAM. It actually is the only Amiga accelerator that
uses the EDO feature of RAM. With EDO enabled at 72MHz, it runs
circles around the MKIII/CSPPC. I got it with the 4000T and luckly it
has the 68060RC50A rev 5 CPU that's supposed to be good to 80MHz. I'm
running it at 72MHz because any higher and my RAM can't keep up. I
need to find 50NS RAM if I want to use 80MHz. Also, many people
complain that their Phase5 custom chips (GALS) get too hot to touch,
well the QP060 has a chipset that stays cold to the touch, even at
72MHz.
I can't complement this board enough.
I tried it in my A3000T
system and it works in that too.
