Well,,, You don't quite have it right. You can use all the memory (including shadow ram). There was an upgrade (about a year ago), which would allow you to utilize all the memory (get back your 384K), no matter how much memory you are using 2mb, 4mb, 8mb, etc. I know because up until about 2 weeks ago we had a Wyse 3216 in our office here, plus several in customer sites. So the answer is, YES you can utilize all the memory, you just need the right update. Hope this helps. ... bob willey ...
