back then I was involved in that stuff and 99% of the Dram problems were
design
related and not alpha particle. To see the alpha particle in real apps
you'd need
a box that had thouands of them running 7x24 for weeks! S100 systems that
ran
that well were prone to the power company failing to deliver before ram
failure was
a problem!

Back in that time frame I used static ram due to the general flakyness I
preceived
of most S100 cards. The best S100 ram I'd used for that time frame (1980)
had
an 8202( Netronics DRAM using 16Ks).
