Federal Communications Commission Radio Frequency
Interlerence Statement (USA Only)
This equipment generates and uses radio frequency energy and
may, if not installed and used properly, that is, in strict
accordance with the manufacturer's instructions, cause
interference to radio and television reception.
It has been type-tested and found to comply with the limits for a
Class B computing device in accordance with the specifications
in SubpartJ
of Part 15 of FCC rules, which are designed to
provide reasonable protection against such interference in a
residential installation. Shielded data cables were used during
the type test; therefore, properly shielded and terminated data
cables should be used
to reduce potential interference. However,
there is no guarantee that interference will not occur in a
particular installation.
If this equipmentdoes cause interference
to radio and television reception, which can be determined by
turning the equipment offand on, the user is encouraged to try to
correct the interference
by one or more of the following
measures:
• Reorient the receiving antenna
Relocate the computerwith respect to the receiver
Move the computer away from the receiver
Plug the computer into a different outlet so that computer and
receiver are on different branch circuits
If necessary, the user should consult the dealer or an experienced
radio/television technician for additional suggestions.

1.0 INTRODUCTION
The TMC-850M supports SCSI devices such as CD-ROMs,
WORM optical disks, hard drives, tape drives and other SCSI
devices that conform to SCSI-1 (ANSI X3.131-1986) orthe 8-bit
wideSCSI-2 specifications.
The
TMC-850M is an advanced design that requires no user
configuration
in mostinstallations. It is a true PLUG & PIA Y@
host adapter for PC XT/AT and 386 computer systems. The
BIOS automatically adjusts for use in the system. The SCSIhost
adapter uses no DMAchannels,
no I/O ports, and no interrupts
under PC/MS-DOS. All operations are memory mapped.
The standard configuration uses
8K of memory space at address
CAOOO in the system (the area reserved for ROM BIOS).
1.1 TMC-850M Features
• Future Domain SCSI BIOS supports a maximum of two SCSI
disk drives. Additional devices require a separate driver.
• For PC XT/AT bus systems.
• Highperformance.
• 50-pin internal SCSI and 25-pin external SCSIApple signal
connectors.
• Jumpers: Six alternate addresses (fourjumpers) and two
interrupts (3 and 5).

2.0 CONFIGURATION
2.1 Factory Configuration
The TMC-850M SCSIhost adapter and ROM BIOS are factory
configured as follows:
• BIOS/HostAdapter Address: CAOOO (Wi, W2 OPEN)
(W3: 1-3,2-4, OPEN)
• Interrupts used: None under DOS, jumper set for
interrupt 5 (W7)
• I/O Ports used: None
e The SCSI BIOS supports up to two hard disk drives. Other
devices require a separate driver.
$ If the factory configuration meets your requirements, proceed
to Chapter 3, INSTALLATION.
If you need to modify the
configuration
of the TMC-850M, read Chapter 4,

3.0 INSTALLATION
3.1 Pre~InstaUation Instructions
Step 1. The tools required to install the TMC-850M and most
hard disks or tape drives are:
• Screwdriver or 3/16" nutdriver
• Installation instructions for the particular disk or tape
drive
Step 2. Place the system unit switch to the
OFF position.
Step 3.
Tum OFF all external equipment.
Step 4. Remove the system unit cover by fonowing the
instructions provided with the system. For IBM PC/AT
systems, use the screwdriver to remove the screws at the
rear
of the system cabinetand slide the unit cover
forward and off. See diagram below.

Step 5. Locate an unused 8- or 16-bitexpansion slot in the system
unit. Using the screwdriveror 3/16" nutdriver, remove
the screw holding the system expansion slotcover in
place by turning it counterclockwise.
3.2 Internal Installation
The following steps are for installing SCSIperipherals inside a
system cabinet. Proceed to Section 3.3,
External Installation, if
using an external cabinet.
Step 1,

Locate the 50-pin SCSI ribbon cable and install one end
on the 50-pin SCSI header J2 on the TMC-850M. The
red
or blue stripe on the cable should be aligned with the
side of the header labeled 1. See the figure below:

Step 2. Align the TMC-850M board with an 8- or 16-bit
expansion slot and firmly plug it in. Reinstall the screw
to secure the TMC-850M in the expansion slot.
Step 3. Pictured below is a typical installation with a hard disk
drive and a half-high tape drive in a PC/AT.
