Miller Technology’s M-80 single-board microcomputer has a Z80 CPU, sockets for 2K/4K of
PROM, 2.1K ofRAM, 16 highly flexible l/O lines, and a system clock. The board also provides a
breadboard area and 12 decoded address strobes. Designed for test equipment, smart peripheral
controllers, and dedicated control and processing applications, the 4.5″X6.5″ board can be
mounted in a card cage or by standoffs. Two software packages, Wang’s Tiny Basic and Miller
Technology’s M-80 system monitor, are optionally available. Unit prices start at $28.50 for the bare
board, $69 for a kit, and $185 for a fully assembled and tested board. The assembled board has a
one-year guarantee

Single board microcomputer, M-80, has a Z-80 CPU, sockets for 2K/4K Prom, 2.1K RAM, ·16 highly flexible I/O lines, and a system clock. The board also provides a breadboard area, and 12 decoded address strobes for easy user customizing. The 4.5-inch by 6.5-inch board was designed for test equipment, smart peripheral controllers, and dedicated control and processing applications. The board may be mounted in a card cage or by standoffs. Two software packages are currently available. A powerful monitor contained in a single ROM enables the user to dump or enter data into memory, set breakpoints, control I/O lines, or download programs from another computer. An integer Basic provides 30 functions and commands, and permits calling machine language routines. Both monitor and Basic use serial I/O for communications. Unit prices start at $28.50 for the bare board, $69 for a kit, and $185 for a fully assembled and tested board.

The RTI-1221 analog I/O board from Analog Devices was designed specifically for Pro-Log 8080 and 6800 based microprocessor systems (pre STD Bus). The RTI-1220 is a 16-channel data acquisition board while this RTI-1221 is a 4-channel analog output. These were introduced in 1977 with the RTI-1221 priced at $235

Analog Devices also made an RTI-1201 for Intel’s SBC-80 multibus platform.

Prior to their development of the STD Bus, Pro-Log offered non-bussed boards and systems. The PLS-868 is listed as a new product in the 1977 Pro-Log Price List and Short Form Catalog. Pro-Log’s PLS (Programmed Logic Systems) are described as an “Edge Connected Card System”, which, in Pro-Log parlance, means a card system that is expandable via an ad-hoc point-to-point wired connectors, i.e., not a through-bus backplane. While these cards were mounted in a card cage, the edge connectors were typically wire-wrap or solder eyelets and required system specific configuration. Pro-Log did offer pre-wired card cages for standard systems.

The PLS-868 is a single board computer (including RAM, ROM, and I/O). In addition to this stand alone single board computer, in 1977 Pro-Log offered two other M6800 based CPU cards, the 8611 and 8611-1. These cards were CPU only and required additional cards for memory and I/O.

The catalog provides the following description:

The 6800 is well suited to small scale data processing applications and is also capable of high speed bit manipulation for control applications. The PLS-868 allows the designer to select either RAM or 1/0 in memory base page 00 for use with high speed direct instructions. Expansion to ten additional Input ports and twelve additional output ports through simple ribbon connector. Single +5V supply.

Includes 6800 Processor with one microsecond cycle time, crystal clock, two interrupt inputs, power on and external reset, 1024 bytes of D 1004 RAM (2 114orequivalent), with sockets for additional 1024 bytes, and sockets for 8192 bytes of D2002 PROM (lntel2716 or equivalent), 16 TTL input lines and 24 TTL output latches. Requires +5 VDC . Does not include PROM
