I just remembered that one of my Mega ST has a TOS 2.06 upgrade on it. So, I figured that I should install it on my STacy. It’s this one:

First step is to solder header strips on the STacy motherboard expansion. Then I’ll use connectors instead of solder so it will be plug and play. I was going to install them for STaceX anyway.
The ROM socket is 32-pins, but not 100% pin compatible with 27c010 or STE. But, apparently pins 3-30 (1-28) are 100% pin compatible with Atari 1mbit mask roms. So I figure the TOS 2.06 upgrade is plug and play.
This will settle the question whether or not the STacy needs a special TOS for the LCD screen. I’m pretty sure it will work.
I will do the LCD upgrade at the same time. It will be a busy week and I have a funeral trip next weekend so I’m not sure if I can get it done this week. Will keep you guys posted.
