The memory test code in the cartridge is just a rewrite of the standard kernal routine, only it checks every 256th byte instead of each byte. The kernal and Basic routines never use bank 0, so they dont't check for it - therefore neither does my cartridge :) And the 8088 card would even not see this bank due to address translation on the card.

Hi all,

I use Michaus cartridge on my 710 and 610 even when I don't need IEC 

support, just for the fast boot.

I am working on installing RAM to BANK 0-14 on my 610.

It looks like the RAM identification on startup doesn't recognize  

installed RAM in BANK 0.

With RAM installes in BANK 0-14 it reports only 896 kb, not 960 kb.

While testing I also ran RAM only in BANK 0-3, which reported 192 kb.
