I would like some general information on 68020 upgrades for the Mac,
particularly on the various ones from Levco.
Some specifics I am particularly interested in...if you upgrade a Mac+ to
a 68020 with one of Levco's upgrades, how is memory reallocated? Does
Levco's "fast" RAM become low memory where all the system globals and such
live? Do you loose access to the 1Meg already in the Mac+?
Particularly...can you use the "slow" RAM in the Mac+ as a Ramdisk/Cache
while having the system/finder/applications running in the Levco "fast"
memory?
Does the Levco upgrade work with System 4.1/Finder 5.5? Do you have to patch
the system software at all? What software does Levco include with their
upgrade?
Is it possible to disable the Levco upgrade from software (without physically
removing it) so the machine will act as a normal Mac+ again?
How big a deal is it to install the upgrade? Do you have to send the whole
machine to Levco or can the installation be done by any Apple service tech?
Finally...does Levco have any special pricing for Universities (members of AUC)
