Please Help to Indentify this Apple Stuff

First of all,  Is this the right newsgroup?

I recently bought 3 old Apple // type computers from a junk store.  Also 
included were some cards and I got a couple of woking disks.
It has been many years since I was interested in Apples and then I only 
knew about the //e, so some of these questions might be pretty basic.

decription, computer 1:
-normal apple casing.  Name plate on top cover is a thick brown sticker on a 
larger shiny aluminum plate. It has an apple picture with a straight rainbow 
colours to the left of the apple, and the word "apple" on the right.  The 
keys are dark grey.  There are no open/closed apple keys, no  up/down arrow 
keys.  In the lower left corner is an unmarked key with a light on it.  This 
key doesn't seem to do anything. When I press it the light doesn't come on 
or off, and it does not change text from upper to lower case.  
It seems to have 48k memory and 2 16k memory expansion boards.  The 
motherboard is marked "unitron" and the power supply is a gold colour and 
marked "apple".  It says "apple ][" when I start it up.

computer 2:
-really ugly, thick translucent white casing with a top cover with lines 
across the top and it doesn't fit very tightly.  No brand name markings on 
the casing.  The keyboard has light grey and tan keys.  It is similar to the 
first keyboard, but with the addition of a "function" key on the lower left 
and a "scroll" key on the lower right. The key with the light on it clicks 
into an up or down postition and works as a caps lock key.  The power supply 
is marked "unitron" and the motherboard is green and has no 
manufacturer markings.  It seems to be 48k and says "apple ][" when started. 

Computer 3:
Similar casing design as #2 but no lines across the top and better fit and 
finish overall.  Grey in colour with no markings.  Brown keyboard, no 
function or scroll keys.  The caps lock key functions electronically without 
locking into place.  It also serves as a function key and when pressed with 
any other key it writes whole BASIC commands that are written on the side of 
the key.  The power supply is marked "tiger".  It seems to have 64k memory 
on the mother board and will not function with the 16k memory expansion 
cards.  It says "OS-21" when it boots up.  There is a whole bunch of wierd 
video wiring connected to a card and to a horisontal circuit board that 
connects into a chip plug and onto pins on the motherboard marked "video".  
Only the standard connector on the motherboard works with my mono monitor.

Unidentified cards:
All three of these computers have a similar card with two wires coming off 
of it for vidio.  On #1 and 2, it is simply a card that has a standard video 
connector.  Neither of these works with my zenith monochrome monitor on the 
40 or 80 column setting, nor do they work on a colour tv.  What are they?

Computers #1 and #2 also have an identical card with no connectors.  One is 
marked "solartron", the other marked "Z80"  They don't seem to do anything 
either.

Unknown software:

-Something called "apple //  CP/M 44k ver.2.20B"   
-"Diversidos"
-"Applewriter"  - Seems to be something like a really bad wordprocessor?


I would appreciate any information.
