I was wondering if anyone could tell me if these would work in Blizzard 12x0/PPC accelerators? I am worried about electronic compatibility. I am aware of space restrictions/issues.
They are 72-pin EDO memory modules, however also ECC. Here's the best description I could find:

HP 128MB 50ns ECC EDO DIMM Memory-Module für HP B Class Workstations(2x A3830-60001 = A4517A 256MB ECC EDO DIMM Memory-Module-Kit C200)
