Hi,
First I want to say that the ACA500plus is a great product!
Just got back into my Amigas some months ago and loving it. Being away from it almost 30 years makes you forget and the ACA500plus makes it so easy to get back into.
But I do have a problem and wondering if someone knows what might be wrong.
I remembered that I back in the day thought that the all the different memory types in the Amiga was confusing(not as much as a PC though haha) So I might be missing something obvious here.
Well here we go.
First some info about my setup:
- I have a ACA500plus that I use with my Amiga 500 rev 6A.
- I use the Amiga 500 original PSU(I use the same one with my A600 and A1200 both with accelerators without issue)
- I also have a M501-s trapdoor expansion that has 512kb and RTC https://bigbookofamigahardware.com/bboah/product.aspx?id=1033
- My 6A It has a Agnus 8372A and from what I've managed to google it should be able to address 1MB chipram.
The Problem:
When I boot into Workbench 3.2.1 it seems to only seems to show 512Kb chip ram.
In the ACA500plus menu at boot, if I press F10 and go into expert menu, the option "1M Chip RAM expansion" states "unavailable".
Toggling the RTC setting to trapdoor gives me the correct time, so that leads me to "think" that at least the m501-s works(partly?).
Am I correct that with the above I should be able to get 1MB chipram without having to solder any jumpers on the Amiga?
If so what could be the problem, is the m501-s broken, someway to try/verify that?
