The Alphastation 500 is also a very nice desktop machine that
is also rather powerful (provided it has a decent CPU). Alphastation
500 were the high-end EV5 / PCI based workstations in a dark blue

400, 433, 466, or 500 MHz, and has 2 or 8 Mb L3 / Bcache (8 Mb
on 500 MHz version only).
The Alphastation has a 256 bits wide memory bus using industry
standard 72 bit wide buffered ECC DIMMs. It has 8 DIMM slots,
and memory is installed in sets of 4. The maximum memory is 1
GB (512 Mb max on 333 MHz CPUs).
There isQlogic 1020 based wide SCSI bus, early machines had
