ZiLOG Z8 Technical Manual

Following are brief descript ions for a few Z8
applications.
Printers. Input data (typically transmitted via a
terminal or computer) can be sent to the Z8 on
either a serial or parallel port. The Z8 then
transfers the data into the external RAM buffer
via another parallel port, where it can operate on
the data before output to the printing mechanism.

Disk. Disk operations are read or write, with
input received from either the disk or the compu-
ter. Data is transferred to the buffer memory a
sector (128, 256, 512, 1024 bytes) at a time via
the Z8, operated on as required, and subsequently
output to the disk or computer.
Terminal. Input is received from either the key-
board
or a computer. The Z8 device must maintain
at least an input buffer and often the screen RAM.
