Commodore A 2091-40 - Installing Random Access Memory (RAM) Chips

Installing the A2091-40/A2091 3-23
After connecting an additional hard disk you will need to modify the tool type of the
Park program as described on page 5-6.
For information on jumper settings for SCSI drives refer to Appendix C.
3.4 Installing Random Access Memory (RAM) Chips
You can install RAM chips in the A2091 to increase the memory available to your
Amiga 2000. You can install 512KB, 1MB or 2MB of additional memory.
NOTE: Use only CMOS 256k x 4 DRAMs, with an access speed of 120 ns or faster.
Slower DRAMs will not work properly. Do not use NMOS DRAMs. The use of NMOS
DRAMs will damage the A2091 and void your warranty.
RAM chips are sensitive to static electricity. Contact with a chip when high
levels of static electricity are present could ruin a chip. Touching a nearby
grounded metal surface before touching the chip can help reduce static levels.
Installation of RAM chips should be performed by an authorized Commodore
Service Center, or by your Commodore dealer. Commodore will not be
responsible or liable for any damages caused by improper installation of RAM
chips.
WARNING: If your A2091 is connected to the computer, you must first turn
off the power, disconnect all cables and peripherals, and detach the A2091
from the computer.
The following steps, required to install RAM chips, are explained in detail below.
1. Disconnect the A2091 from the Amiga.
2. Insert the RAM chips.
3. Set the RAM size jumper.
1 = Disconnect the A2091 from the Amiga
With power off and all cables disconnected, remove the screw holding the A2091
in the slot. Remove the A2091 by pulling the card straight up.
If the hard disk is installed in a drive bay, disconnect the ribbon cable from the card.
