1982-12 (Byte) "Versatile Single-Board Computer"
The 128-I single-board computer from Insight Enterprises features 128K bytes of RAM (random-access read/write memory) and a Zilog Z80A processor. Both 5¼- and 8-inch double-sided double-density floppy disks are supported, and the CP/M- based 128-I is supplied with CTC (counter/timer circuit), DMA (direct memory access), PIO (parallel input/output), and other support chips. Standard equipment includes two software-programmable RS-232C serial ports, a Centronics-type parallel printer interface, an expansion bus, and a smart Winchester disk controller interface that can handle Western Digital, IMI, and Corvus intelligent disk controllers.
The 128-I costs $600 and can be ordered from Insight Enterprises Corp., Suite 12, 373 North Western, Los Angeles, CA 90004, (213) 461-3262.

1983-12 (Byte) "Single-board Computer is CP/M-compatible"
The single-board EQ-4 from Insight Enterprises is compatible with CP/M 2.2 and 3.0. It has virtual memory-mapping circuitry that lets the Z80A central processor and the DMA controller directly access 128K bytes of RAM, 2K bytes of EPROM, and 4K bytes of video memory in 8K-byte blocks.
Interfaces incorporated into the EQ-4 include SASI, four serial RS-232C channels with independently programmable data rates ranging from 110 to 76,800 bps, a Centronics parallel printer, and floppy-disk ports. The floppy-disk controllers can handle single- and double-density 5¼- and 8-inch drives simultaneously. CTC, DART, and PIO peripheral controllers are standard. The parallel keyboard input accommodates 7- or 8-bit ASCII-encoded boards with jumper-selectable active high and low strobes. Horizontal and vertical sync signals and composite video output compose EQ-4's video features. Standard Microsystems' 8002 video-display attributes controller provides the EQ-4 with an on-chip character generator, 128 characters in a 7- by 11-dot matrix, and character-oriented, wide- and thin-line graphics. Attributes supported for each character are reverse video, character blank, blink, underline, and strike-through.
The single-unit price for the EQ-4 is $750, which includes CBIOS, utilities, and source codes. Complete specifications are available from Insight Enterprises Corp., Suite 12, 373 North Western Ave., Los Angeles, CA 90004, (213) 461-3262.
1984 (OMNI complete catalog of computer hardware and accessories) "SINGLE-BOARD EQ-4"
The Single-Board EQ-4 from Insight Enterprises is a computer kit that's compatible with CP/M 2.2 and 3.0. It has virtual-memory mapping circuitry that gives its Z-80A processor direct access to 128K of RAM, 2K of EPROM, and 4K of video memory in 8K blocks.
The EQ-4's interfaces include SASI, four serial RS-232C channels (whose independently programmable data rates range from 110 to 76,800 bps), a Centronics parallel printer port and floppy disk drive ports. The floppy disk controls can handle single- and double-density 5¼-inch and 8-inch drives simultaneously. CTC, DART and PIO peripheral controllers are standard. The parallel keyboard input can accomodate a 7-bit or an 8-bit ASCII board. EQ-4's video features are horizontal and vertical sync signals and composite video output. The board's on-chip character generator supports 128 characters in 7 by 11 dot matrices, character-oriented wide- and thin-line graphics, reverse video, and character blanking, blinking, underlining, and strike-through.
This unit is not for the inexperienced. The average user will need some training to be able to successfully assemble the EQ-4 into a working computer.
