15 4096 8-bit bytes per module Static memory, no clocks required Interfaces with imm4-42 4-bit Central Processor Module Single + 5V power supply Low power requirements Provides Intellec 4 with 4K bytes of read/write program memory

The imm6-28 RAM Memory Module is a standard 4K x 8 memory module de­ signed for use with the Intellec 4 Micro­ computer Development System. This module contains address and data buffers, read/write timing circuits and is implemented with Intel's 2102 1K x 1 static RAM . This basic memory module is organized as 4096 x 8. When used with the imm4-42 4-bit Central Processor Module in the Intellec 4, the imm6-28 becomes a read/write program memory. This feature in the Intellec 4 greatly enhances the user's RAM Memory Module ability to quickly develop programs and bypasses the step of programming PROMs.

The imm4-60 Input/Output Module provides eight 4-bit input ports and eight 4-bit latching output ports for use with the imm4-42 Central Processor Module. This module allows expansion of I/O capability of an Intellec 4 or custom MCS-4 system without additional memory. On-board decoding permits a maximum of two I/O modules to be interfaced with the imm4-42 Central Processor Module for up to sixteen 4-bit input ports and sixteen 4-bit latching output ports. In this configuration the lower four input and output ports on one Input/Output Module I/O module are suppressed because the . ports located on the imm4-42 take precedence. All I/O lines are available at the top of the module and all are TTL compatible.
