From a friend who cannot access Notes: ------------------------------------- On the new AMIGA 500, it is possible to install 512K of additional memory on the main board. By keeping the extension card A501 the total amount of memory should be 1.5 Mb. Unfortunately after having installed the 4 additional chips on the main board my Amiga continue to see only 1 Mb (with the A501 card). Do you know if something special has to be done (hardware configuration change, software to install...) ? For your information the Gary chip is a 8372 (new version) and the PC boards layout is different of the hardware schematics shipped with the product. By default the extended memory is mapped in C00 000. If you change J2 position to map it in 019 000 then the 1Mb on board are seen but if you plug the A501 board there is no change. Any information is welcome, thanks in advance for your help. Best regards Jacques D (you may reply or send answers directly to me , I will formward them. My mail address is olivier@hpgnd.hp.com).
