Performing the Upgrade
Installing the SCSI Host Adapter Circuit Card
NOTE :
Follow instructions to install this card as shown here. Do NOT use the
instructions shipped by the manufacturer with the card.
1. Follow the steps under ‘‘General Steps for Circuit Card Installation’’ in
Chapter 3. Refer to Chapter 3 also for proper jumper and switch settings
for the SCSI circuit card.
2. With the MAP/40 SCSI cable in hand notice that there is a single connector
located approximately 12 inches from the next nearest. Attach this connec-
tor to the SCSI controller card and dress the cable neatly down the side
and rear of the power supply.
3. With the new floppy drive cable in hand route it similarly. Note at the SCSI
controller end the SCSI cable should be under the floppy cable for best
routing.
4. Connect the disk activity cable to SCSI controller card with the two popu-
lated receptacles, of the four, toward the short end of the card.
Installing the Floppy Disk Drive
1. Slide the floppy disk through the front of the MAP/40 in position 1 (right
most).
2. Re-attach any cables to the floppy drive at this time.
3. From either side of the peripheral bay, insert the two screws on each side
of the drive unit. Tighten these screws (4 screws total).
Finishing Up
Reinstall the video card in slot #10 using the step outlined in ‘‘Installing a Circuit
Card in the MAP/40’’ in Chapter 3 of this book.
Go to Chapter 2 and reverse the process you used to get into the MAP/40. There
are also procedures there to replace the dress panel and left cover.
