I just picked up an Apple ][e complete with DuoDisk
box and orange
Opening up the case reveals that it has a number of cards plugged in
including a memory expansion card - does anyone know what size RAM
this gives me? how can i check (forgive me for i have not RTFM yet!).
If it's the standard Apple-issued card for the Aux slot, there are two
varieties: a 2k board that adds only enough memory to make 80-column
video work and a (more common) 64k board, which gives your Apple a total
of 128k. You should be able to tell which of these you have by looking
at the chips on it -- the 64k model will have eight 4164 chips or two
of whatever the later 256kbit chip's model number was (41256?). Other
manufacturers offered Aux-slot boards with more than 64k. If the
memory expansion card is not an Aux-slot one, but fits in one of the
standard seven slots instead, these were normally populated with 256k
but could be expanded up to 1mb.
It seems to work fine, so my big question is can i use
any old 5 1/4"
disks in it? is it capable of formatting any old 5 1/4" disks? I ask
for two reasons: 1) so i can make back-up copies of the DOS 3.3 disks
and 2) so i can save stuff.
The Apple format was single sided, single density, so almost any disk
should work. The DOS 3.3 system master disk should have a program called
COPYA which will make backup copies of disks.
