Would anyone have any ideas as to what might be causing a problem
with my Apple ///...it does the following:
1) the only disks it will boot are the disks for the Apple ][+ emulation,
the CP/M 2.2 diskette for the Softcard ///, and the 'Apple /// Dealer
Diagnostic' diskette. All other diskettes give a blank screen, though I
have two full sets of the Apple /// systems disks.
2) The diagnostic diskette keeps reporting a RAM Map failure when I try to
run a RAM test, on either the 5V or 12V settings, and it then asks me for
the amount of RAM in the machine. No matter which choice I've given, it
just goes back to the same error. As far as I know, it is a 128k machine
with the RAM daughtercard below the keyboard. The amount of RAM was gotten
from the factory sticker next to the PSU on the bottom
of the machine.
3) Of the diskettes that will boot, once booted, the machine runs fine,
including being able to boot Apple ][ DOS 3.3 and being able to run Wordstar
under CP/M 2.2.
Any help someone can provide as to trouble shooting this would be
greatly appreciated since my experience with Apple machines is quite
limited. The machine has a Monitor ///, Disk II for the Apple ///, Softcard
///, and a Silentype printer. It would appear that Apple at least did some
kind of work on the machine at one point as it has an extended warranty
sticker on the bottom from Apple, with the additional 1 year ending on
08/06/83. Thanks.
