Hmm, both of the ones that were originally in this machine (a 2MB and 4MB)
were 85ns. The 2MB was snafu, but now the 4MB has gone bad, too.
I can work around it by booting the reference disk and reconfiguring, then
removing the disk and doing a warm boot, but it's less than ideal!
I'm tempted to hack the 4MB simm and change the presence detect pins so
that the machine thinks it's a 2MB one, which in theory should give me a
happy machine so long as I don't try using that simm alongside any that I
might acquire later.
