Recently I've purchased an ACA500+ ... Also, I've spoken with Jens via email back and forth pertaining to issues concerning it.
I've looked over some of the threads and discovered a few things. My power supple could be an issue, it was also stated that these green screens are not detecting chip ram. When the accelerator is taken out, I've used Amiga Test Kit to test the ACE2b, 2mb chip ram which I just purchased. This tests out perfectly, however very tricky to get in. So, I certainly do not want to mess with it!
I'm using a never used boxed Amiga 500, which was pulled out of storage and used by me. Everything is old - new ... Revision 5 motherboard. Original PSU, from original unused packaging - stored. 1084 monitor never used, pulled from original box and plastic. No extra floppy drive or anything. No trap door memory, I pulled that out. When I first used the ACA 500+ I was able to put CF cards in and see Workbench. Though when I did try to run things in that Workbench, they froze every single time. Now, if I dare try and use the CF card reader it will freeze and brick the accelerator.
Right now I am happy that I finally get it to boot into the menu. More than once I have used the menu ADF update, which from what I understand and read is also a sort of recovery disk. So I created a floppy on my Amiga 4000. Several times I have updated the menu in a recovery style thing.
As I said, right now I am just happy it goes into the menu and boots up. The Starfield menu thing will eventually freeze. If I keep playing it will do something. What I did was put in Amiga test kit. With the accelerator present. The AC2b 2 mb chip expansion I installed tests out perfectly every single time. When I go into testing fast ram. Eventually it does a red screen and the accelerator goes bonkers and freezes.
I'm on a prayer that I've gotten it this far again. Still, I'm not upset or disappointed if I can not even get it to work. I've ordered so many great things from Individual before. This is an exceptional product. I think it's just in an extremely vulnerable sensitive place by being on the side port. These contacts and whatever themselves can become very sensitive with the card and whatever else. Ideally, it's genius and I couldn't see needing more power than this for a 500. Electronically brilliant and possibly design flawed without having a casing or something.
Still if it works, doesn't work or whatever, I will continue support here. I'm not letting it stress me. I'm not fully confident I may be able to get this to work. Stranger things have happened with patience ...
