Re: A501 memory card detection

Does anyone know, besides PIN 32 on CNX (aka /EXRAM on Agnus), what checks the A500 performs to consider the A501 online and available for use?

Does the boot sequence include writing a byte/word out to the memory, and then reading it back in? Prior to making it available for use?

I've got pin 32 grounded, and booted off a workbench disk, "avail" still shows only the initial onboard 512k.

Thanks

If you have a problem with yours...I have a spare one I can give you for free 100%. All you have to do is pay for shipping and handling which is not much and it is all yours.

I bought one thinking my A500 will come with 512 KB CHIP RAM..but it came with A501 itself...so now I have a spare one not knowing what to do with it. You can have it for free. Just pay for shipping and handling.
