[Simh] 3.8-2 rc2 Windows XP disk access issue

[Mark Pizzolato - Info Comm]

Hi Mark,

I'm glad you've got this issue solved.

If you picked precompiled up binaries from https://github.com/markpizz/simh/downloads you may want to pick up the latest precompiled binaries.  These include optimizations which increate the simulator instruction execution speed by 20% and also fix some disk sizing issues if you happen to use the vax780 simulator and RP disks.
