I have the ACA1221LC + ACA500Plus config on a Rev6a A500 with 0,5 MB chip + 0,5 MB slow RAM.
In the booklet that came with the ACA1221LC, it says that there's 11,5 MB usable RAM on the card. But my system sees 8 MB + 1,5 MB fast RAM.
1. Why doesn't it sum up to 11,5 MB (I assume that chip ram comes from the original machine, but even if it doesn't it still adds up to 10,5 MB)?
2. What is this separate 1,5 MB chunk of memory?
3. Is it possible to somehow utilise the memory on ACA500Plus?
Cheers! Sorry for noobish questions.
