[sebhc] H90

[Bill Beech (NJ7P)]

Yes, I was suprized as I figured the heat would have gotten them.  I 
suspect the 8-inch and even the 5-inch floppies write with a lot more 
current that the 3.5's.  I have 5 year old 3.5's with read errors.

I am still booting the CP/M system from a disk written in 1983 when I 
was in Korea.
