- DSB-8100 Product Specification
-
- The DSB-8100 is a small but powerful general purpose
- microcomputer useful for a wide variety of communication, data
- acquisition and data processing tasks. The 64180 processor
- executes a superset of the Z80 instruction set allowing it to run
- any of the wide variety of CP/M programs available. Assemblers
- are available specifically for the 64180 and a variety of high
- level languages such as Basic, C, Pascal, and others are also
- available.
-
- The basic clock rate of the 64180 is 6.144 MHz but executes
- faster than an 8 MHz Z80H because it requires fewer clock cycles
- to complete most instructions. Two on-chip DMA channels can be
- used for memory to memory and memory to/from I/O data transfers.
-
- Memory consists of 256 kilobytes of dynamic RAM and a JEDEC
- bytewide memory socket accepting devices up to 32k. The RAM
- array consists of eight 256k by 1 150ns dynamic RAMs and is
- directly accessed through the memory manageement unit integral to
- the 64180. The bytewide memory socket is preconfigured for an 8k
- x 8 device (2764) with a strapping option allowing larger memory
- devices if required.
-
- Two RS-232C serial channels are internal to the 64180 and handle
- asynchronous communications up to 38,400 bps with one handshake
- line on the console port and three handshake lines on the
- auxiliary communications port. Two 10-pin (2x5) headers allow
- the DSB-8100 to be connected with straight ribbon cables through
- a DE9 (IBM PC/AT) type connector to most types of serial
- peripheral devices.
-
- The standard Centronics-type parallel printer port is provided
- with a 26-pin header for connection to a ribbon cable, and is
- compatible with the IBM 26/36 pin cable.
-
- The floppy disk interface uses the Western Digital 1773 (1793
- code-compatible) and supports 3.5, 5.25 and 8 inch diskette
- drives, single or double-sided, 48 or 96 tpi, single (FM) and/or
- double (MFM) density.
-
- A SCSI (Small Computer Systems Interface) port, supported by a
- 5380 device, is provided to connect the DSB-8100 to a Winchester
- disk drive or other SCSI-compatible peripheral device(s).
-
- The DSB-8100 was designed to fit in an enclosure alongside a 3.5
- inch drive. Dimensions are 3.875 x 6.750 inches. Power
- requirements are +5v @ 1.2a and +12v @ 20ma. (-12v for RS-232C in
- generated on-board)
