8085 Expansion Board
Michael Vossberg, one of the founders of SGE & Associates,
has spent the last 15 years working as an Electrical Engineer for various
companies and a part time instructor of digital electronics for Kirkwood
Community College in Cedar Rapids, Iowa. Over the course of these
years Michael has established a five part course sequence that is based
on Albert Malvino's text, "Digital Computer Electronics, An Introduction
to Microcomputers". Courses Digital I - Digital III follow
the traditional path of lecture, lab and experimentation. While Digital
IV and Digital V are based on the student constructing an Elenco
MM-8000K 8085 trainer in Digital IV and assembling the 8085 Expansion Board
in Digital V. These two boards can be interconnected to enhance the
understanding of microprocessor based systems.
The features of Elenco's MM-8000K include: a compact single board trainier
with 2816 EEPROM, hex keypad and two digit display and a monitor routine
to complete the project. Once completed the student has a self contained
development system with which he or she can use to program and run 8085
assembly code.
The 8085 Expansion board can be connected to the MM-8000K trainer to
extend the trainer to include two 8255 PIAs, 2816 2K x 8 EEPROM, 2K x 8
Static RAM, LCD display and an A/D converter. With these components
the Expansion board can be attached to the MM-8000K to develop programs
that use the PIAs, A/D, LCD Display and program 2816 EEPROMS. Once
the Expansion Board is properly programed it can be detached and run as
an autonomous single board computer. Note: The Expansion Board
requires a seperate 5 VDC @ 1 A power supply.

This page as well as SGE & Associates is presently under construction.
Work is underway to forge an alliance with Kirkwood Community College in
Cedar Rapids, Iowa in an effort to work jointly to offer the 8085 Expansion
board. As more information is known this page will be updated appropriately.
