Re: [emulatorII-list] Booting stops after 3 clicks....

2012-06-15 by Nigel Cruickshank

Swap the first row of digital memory for the last row.  You don't need to have the piggyback board attached to boot it.

I think the first 7 memory chips are the boot sequence chips.  Something like that.

If there is a problem with your boot memory that will flush it out.

This EII was working fine.....

recently,

only gets as far as clicking the drive 3 times then hangs.

Memory test floppy loads fine, and the memory test passes.

Diagnostic document says it could be something to do with memory register selection, check IC84 and support ICs.

Any other suggestions or tips?

thanks
