Amiga 500 vs 500 Plus Hardware Compatibility

[AdelaideAmiga]

Hello everyone,

Just wanted to pick some of your Amiga brains and ask whether anyone here has had any success with hardware designed for the 500 working also on the 500 plus and vise versa?

I understand that these machines are fairly similar with just a few minor differences.

Looking forward to hearing from you all here.

Regards,

George

Hi all again,

I recently picked up a memory expansion unit (1MB) that was designed for the a500+ (Gigatron A500 Plus: http://amiga.resource.cx/exp/gigatron500plus)

When plugged into the Amiga 500, it does not recognise the expansion.

Does anyone know whether this is a hardware incompatibility issue or a fault with the expansion card?

Kind regards,

George

- Yes, it recognises zero additional memory.  I.e. the same memory is recognised with or without the ram card.  By the way this information is being accessed from the main workbench screen where the bytes are registered on the top centre of the screen.
- The machine is a completely stock 500, with a gotek system.  Agnus chip is 8371.
- There are no other expansions

Thanks for your help so far everyone!

Much appreciated

George
