The System at a Glance

The block diagram in Figure 1 shows the principal features of the AM-6060. This is an introductory

view. Details are presented later.

➀

Chassis

—The AM-6060 comes in a new, attractively styled deskside chassis. There’s room

inside for CPU components and a mix of disks, tapes, and other peripherals. A Wide SCSI bus is

standard in one AM-6060 model.

➁

Ethernet

—A 10BaseT Ethernet port, backed by AlphaTCP and other standard networking

software, connects the AM-6060 to user workstations, WANs, the Internet, and so on.

➂

Serial ports

—Four RJ-45 serial ports, with full modem control, are standard. Most AM-6060

sites will use one, and often two, of the ports for modems. More information on serial port usage

appears later in the bulletin.

➃

External SCSI port

—Attach a RAID subsystem, a ½-inch tape controller, and other devices

at the external SCSI port.

➄

Upgrade to AM-6000

—A field upgrade kit converts the AM-6060 in its original chassis to an

AM-6000 Business System. Optional AM-359 cards in the AM-6000 provide a total of more

than 50 serial ports. The four standard serial ports in the AM-6000 replace the four serial ports

originally installed in the AM-6060 (➂ above).

Technology in the AM-6060

The central processing unit of the AM-6060 consists of a main processor board and a small plug-on

auxiliary board. The processor board is identical to the Roadrunner 060 board in the AM-6000. The

auxiliary board, model AM-301-10, is a new product.

The technology and functional specifications for the AM-6060 main processor board are the same as

those announced earlier for the AM-6000. Differences in SCSI configurations are noted in the

following description:

Superscalar CPU At the heart of the AM-6060 main processor is a Motorola MC68060 micro-

processor. The 68060 offers superscalar integer performance of over 100 MIPs

at 66MHz. (“Superscalar” here means the CPU can execute two scalar

instructions, such as multiplying one number by another, simultaneously.)

This performance far exceeds that of any prior 680X0 microprocessor. The

MC68060 includes two 8KB on-chip caches for fast access to instructions

and data.

External Cache The AM-6060 main processor is equipped with 64KB of external cache,

mounted on a small plug-in circuit card.
