Both the serial printer port and the parallel printer port share slot1.

You can select which one you wish to use with a switch that's on top of

the compter, next to the keyboard.

The Laser 128EX has a built in Memory expansion card, mapped to slot 5.

While the Laser 128 doesn't come with this card, it could (at one time)

be purchased seperately. This card is Laster 128 specific, it's an

internal card, and can hold up to 1 meg of ram.

The slots are mapped out as follows:

Slot 0: 40-column display interface

Slot 1: Parallel or Serial printer interface

Slot 2: Serial communication interface

Slot 3: 80-column display interface

Slot 4: Mouse/Joystick port

Slot 5: Memory Expansion interface / or external expansion box

(depends on which way you set the jumper)

Slot 6: 5.25" drive interface

Slot 7: 3.5" drive interface / or external expansion box

(I don't believe the Laser 128 supports 3.5 drives without an extra

card)

Note: The jumpers are located underneath the rom door on the bottom of

your computer

The 50 pin port on the left side of you machine is an expansion port.

You can hook up an expansion box to this, and plug in up two two

standard apple II cards into this expansion box. If you don't have the

expansion box, you can still plug any standard Apple II card into this

port.

Hope this helps.
