To Do
It Right.
To make
a
Winchester
disk
for just Apple®
II.
T hat's how we set out to design our hard disk for
the Apple®
II.
To understand the needs of serious
users and programmers, and to correct the errors
of our predecessors.
You want user-friendliness. So we wrote hard disk
versions of Apple DOS, CP/M® and Pascal that
are highly user-friendly and loaded with
useful features.
0
Auto-boot hard disk
0
Menu-driven utilities
0
Single-keystroke program execution in DOS
0
Disk search with wild cards, and many more
You want low-cost backup. So we wrote backup
utilities that make floppy backup convenient.
0
File compacting to reduce the number of floppies
0
Volume selective backup in all operating systems
0
Automatic diskette sequencing to ease floppy handling
You want compatibility. We maximize compati­
bility with existing software and peripheral cards.
0 9K
interface card leaves main memory untouched
0
Interrupts are allowed
0
Boot protected floppies from slot
6
without removing hard disk
D
Automatic slot/drive to hard disk remapping
0
0
And you want support. We do that right too.
Hardware depot service in every region
Software theft-protection on the hard disk
You want flexibility. So we made every
feature variable.
0
From
1
to
16
operating systems on each disk
0
Operating system spaces grow as needed
0
Slot independence
0
Variable size volumes (to
400K
in DOS)
0
Mountable and unmountable volumes (even in CP/M)
0
Custom DOS allowed
Compare the features that matter to you.
And visit our local dealer or distributor for
a demonstration. You' ll see the difference
specialization makes.
You want reliability. We use the leading drive.
And Corona's unique data protection technology.

How to get started with
the 68000 today
FAST, EASY, AND ONLY
$995.
You won't find an easier way to get
started with the 68000 processor. We've
made it both a simple and low cost way.
And we don't just start you with the
bare minimum. We've made it simple to
have a whole plug-in system, and lots of
software.
The 68000 is widely accepted as the
most powerful of the new processors
because of its 32-bit wide architecture,
16 megabyte
addressing range and
many other features.
That's why we've selected it as the
heart of our new Dual Processor Unit.
The DPU is so powerful that it easily
handles complex tasks formerly requir­
ing a minicomputer or a mainframe.
16-BIT AND 8-BIT SOFTWARE
To go with the DPU there's our wide
range of software. Powerful software
like our widely admired CROMIX'
multi-user, multi-tasking operating
system. It's like UNIX" but has even
more features.
You can also run the wide range of
CP/M"' and other 8-bit Z-80 software
presently available for Cromemco
systems because the DPU has an on­
board Z-80A as well as the 68000.
HIGH-CONFIDENCE MEMORY
To go with the DPU's you can use
our powerful new RAM memory units.
These are available in both 256-kilobyte
and 512-kilobyte sizes. They're out­
standing in their price range. They let
you expand to a very large memory with
confidence because of a special error­
correcting and diagnostic feature.
To get started with the 68000 you can
plug this family of DPU and memory in-
to one of our 5100-bus card cages and
use our PS-8 power supply. You can be
in business that easy, that fast.
The new DPU and memory can also
be used in our present Cromemco com­
puter systems.
LOWEST COST
You can see how easy we've made it
for you to start with the 68000.
And at a cost that's by far the lowest
we know of- only $995 for the DPU.
Remember, too, that Cromemco of­
fers a whole series of other cards that
can work along with the new DPU
series. More Memory. Other processors.
GPIB. All kinds of analog and digital in­
terfaces. Color graphics. Terminals and
printers.
So contact your representative now.
Have a plug-in 68000 system working
for you by day's end.
