WHY

SETTLE

FOR LESS -

THAN

A

COMPLETE

6800

SYSTEM

MEMORY

-

All

static

memory

with selected 2102

IC's

al-

lows

processor

to run at

its

maximum

speed at all times.

No refresh system

is

needed

and

no

time

is lost

in

me-

mory refresh cycles.

Each

board

holds 4,096 words

of this

proven reliable and

trouble

free memory. Cost

-

only

$125.00

for

each full 4K

memory.

INTERFACE

Serial control

interface

connects

to

any

RS

-232,

or

20

Ma. TTY control

terminal.

Connectors

pro-

vided

for expansion

of

up

to

eight

interfaces.

Unique

programmable

interface

circuits

allow

you

to match

the interface

to

al-

most any

possible

combination

of

polarity

and control signal

ar-

rangements.

Baud

rate selec-

tion can

be made

on

each

individual

interface.

All

this

at a sensible

cost

of only

$35.00

for

either serial,

or

parallel

type

"Motorola"

M6800

processor

with

Mikbug®

ROM operating

system.

Automatic

reset and

load-

ing,

plus

full compatability

with

Motorola evaluation

set software.

Crystal

controlled

oscillator

provides the

clock

signal

for the processor

and

is divided

down

by the

MC14411 to provide

the

various Baud

rate outputs

for the

interface circuits.

Full buffering

on all

data

and address

busses insures

"glitch"

free operation

with

full

expansion

of

memory and

interfaces.

DOCUMENTATION

POWER

SUPPLY

-

Heavy

duty 10.0

Amp power

supply

capable

of

powering

a

fully

expanded system

of memory

and interface boards.

Note 25 Amp

rectifier

bridge

and

91,000

mfd computer

grade

filter

capacitor.

Probably

the

most extensive and

complete set

of

data

available

for

any

microprocessor system

is supplied

with our 6800

computer.

This

includes

the

Motorola programming

manual,

our

own

very complete assembly

in-

structions, plus a

notebook

full of information

that

we have compiled on

the system

hardware and programming.

This

includes

diagnostic programs,

sample

programs and

even a Tic Tac Toe

listing.
