I have an EIV with EOS 3.00b and I am interested in upgrading to 4.62 but due to the 1mb limit of the cpu flash ram , the upgrade is impossible.
I need to get hold of a 2mb cpu flash ram card but they are rare as s**t !
What do u think guys, is it worth upgrading ?
Unfortunately non ultra models can be upgraded only to v4.62 , missing the most important feature which was FAT support that was introduced in v4.7
A few years ago there was a Russian guy that cloned the card and he was selling it at ebay, I tried contacting him but unfortunately I got no reply :/
There were rumors that there was a 2mb ram chip available that could be used as a direct replacement for the 1mb ram chip (requiring some smd soldering skills) , but no real facts exist.
Does anybody have any info or resources about this ?
