Sorry if this is a duplicate. I posted this yesterday but never received
a copy myself. I suspect our mail wasn't working.

My original mail was as follows:-

With regard to my specific interest in reusing Sparc 1, IPC or Sparc 2 memory
in a Sparc 5 or Sparc 20, this was an absolute NO. (Russ Poffenberger) came up with an
interchangability chart which was useful:-

> The following groupings have generally interchangeable memory.
> SS-1, SS-2, IPC
> SS-10, SS-20*
> Classic, LX
> *Means that there are certain restrictions, usually related to speed.
> If it is not listed, then they are not interchangeable with any other machine.
