Results testing AutoStain machine

Research topics:

Baseline Sharp SM4 as these are relatively plentiful and are known to be very easy to stain (ie wide margin of error for experiments)

2020-08-11 S1 Etch RG 2 hour (no changes)
TLDR: test was mostly invalidated due to preparation error

* Staining visible
* Crystals present

Tried to use less grease to hold sample. Resulted in sample flying off during final wash.
I didn't have time to fish it out and it stayed in the drain tube for some hours.
When I fished it out waste acid had etched it, probably resulting in the half eaten ROM

* Use more grease
* Position sample holder to slightly block drain
* Budget cleanup time for important chips
