Restoration: how far should it go??

I had my Otrona 8:16 upgraded from 256KB to 640KB RAM, so it now has stacked chips. However, that was a mod done at the time (actually, Otrona Advanced Systems had gone under by then, but it was a 3rd party (Brown Enterprises) mod that was current with the machine. What Tony was objecting to is a modern collector hot-rodding an old box by increasing the RAM (or processor, or ...) in a way that would not have been done contemporaneously with the machine.

I thought one DIP had an inverted CS, Though I might be wrong. I did the
stacked thing on my atari 400,
Stacked 8K chips to get 16K. But that was in 82 and the atari H/W
manuals are in the garage.
