  • Hi.

    I have this Amiga500-Plus machine. And if I put a 512k expansion in the trapdoor, it gives 1.5mb Chip. The same with a 1mb expansion, gives 2mb Chip Ram in total. Then I have this a512 expansion. The question is. As the a512 have a passthrough port. Can I extend it with whatever expansion I want? Like if I attach a BooBip expansion after the a512. Will I then get 1mb extra Chip and 512k Slowmem. Like 1mb Chip from expansion plus 512k Ranger upgrade? Or do I need 3xa512 in one row, in order to achieve 2mb Chip plus 512k Slow in total, on an Amiga500-Plus?

  • The question is. As the a512 have a passthrough port. Can I extend it with whatever expansion I want?

    Yes, that's what the product description says.


    Like 1mb Chip from expansion plus 512k Ranger upgrade?

    No, the highest possible expansion on the internal trapdoor port of the Amiga500plus is +1MB Chip ram. There is no possibility to add ranger-mem.


    Or do I need 3xa512 in one row,

    As the A512 manual says, the pass-through of the second A512 MUST stay empty.


    If you want ranger-mem at $00c0.0000, I suggest to add the ACA500plus accelerator, which can give you that exact memory config (and many others).

  • Good to hear that I can use two a512's. Yet a shame that the Amiga500-Plus can not adress aditional memory from the trapdoor as ranger/slow mem. :-( The boobip that I have, did come with an Gary adaptor. So I will check if it conflicts or not, with my TF-530, once I get the MeanWell PSU in the mail. The TF-530 did collide with Chipmem that I had adressed with the Gary adaptor, as to why I did the ChipMem-mod/500-Plus-Upgrade on my 500. Just a shame that the 500Plus can not do what I want.

  • There are no "recommended" cards, because there's only a single negative report, and that's from my side: I have a Hama 4G card that does not work. Other cards just work - there's just no negative reports since the ACA500plus is on the market.
