Regarding the 1MEG upgrade of the 520ST, the European 1040ST is simply a piggybacked 520ST but there are no resistors in the RAS and CAS lines and they seem to be reasonably reliable even with TOS in ROM (according to my source). So why do Americans need the resistors? One theory: some, but perhaps not all, of the upgraders have damaged their DRAMs in some way when installing them and the resistors allow these DRAMs to function or prevent further damage. Further note: it has been said that the critical period for 1MEG upgrades is between 3-5 months after the change (if anything will happen it usually will happen then - assuming, of course, that the modification was successful initally). So, if you made the upgrade without the resistors and have not gone back to put the resistors in (perhaps because everything is fine with your system) and it has not been 5 months since you did the upgrade it might be wise to go back and do so. Adding the resistors shouldn't hurt performance of the ST and may prevent you from damaging your DRAMs later.

I have not seen any 520ST+ (1040ST without disk drive) here with TOS in
ROM. The reason for this is, that the German language is much more
redundant than the English language. So the German TOS is always a
little bit bigger than the US version. Why have those cracks at ATARI
not put the desktop resources into a file, in order to load this
from disk when booting?
