I´ve written a new article where I describe hacking the firmware of three recorders so that they might use the penultimate ATRAC version. Most of you probably already know that the R-500 / 700 can be hacked to use DSP Type-R - but I bet not one of you know that the same can be done to the MZ-R 900! Read all about it:

This is a similar question that we are asking ourselves right now on Laserdisc Plaza MD french forum, is it possible to "upgrade" a MDLP type-R deck to a type-S one.

I don´t think so - the ATRAC ICs are completely different, they are not only different hardware revisions but completely new chips. To know for sure a look at their respective Service Manuals should clear things up.
