ADDING RAM TO THE BOARD
SIMM memory chips are designed to be easily installed and allow the flexible
configuration of an Amiga 1200’s RAM capacity. Each chip has a fixed capacity
measured in Megabytes (Mbs). The higher the number of Megabytes, the greater the
amount of storage available to your Amiga.
The AMITEK expansion board has one SIMM socket (see fig. 2.1), that can be
populated with 1

SIMMs. The FAST RAM used is of the 72-pin
SIMM type and is the same as the RAM available in the high specification Amiga
4000. The AMITEK board will accept RAM that is 80ns (nanoseconds) in speed, or
quicker (the lower the nanosecond rating, the faster the RAM performs). This SIMM is
either supplied as part of the product that you have purchased or can be bought from
your local Amiga dealer.
Fitting SIMM boards is an easy operation which should take only a few seconds. It
can either be done before the board is installed in your Amiga or when you decide to
upgrade your machine’s memory and the board is already in place. In the latter case,
you will need to remove the AMITEK board from the Amiga’s trapdoor slot making
sure power is switched off before removing.
If you are in any doubt about fitting the SIMM boards, contact your dealer who should
be able to help.
NOTE 1
- The 72-pin SIMM was designed to allow the user to fit it into a SIMM socket
only ONE way. It is not possible to install a SIMM the wrong way round.
NOTE 2
- The AMITEK Expansion will not allow the use of slower PCMCIA memory
cards. If you have previously used a PCMCIA RAM card, you will notice a significant
speed increase in your Amiga when you use this AMITEK product.
