Oh, for the love of god, it wasn't that difficult.

We were an SCO shop for a decade. Maybe more. It worked really well for us.

We had WordPerfect, Lotus and dBase.

You want difficult, try using Tandy Xenix with Scripsit, Multiplan and

Please explain how you duplicated it? If you had a boot floppy in the drive 
then is it possible that enough of the model III or 4 ROM image loaded to allow 
for ROM basic to exist?

Make that the September 19th, 1979 (not September 18th), issue of Info World 
mentions "the Control Logic Industrial Microcomputers, Interfaces, and Logic

Generic Cassette interfaces (was: data cassette and robotic arms)

[Kelly Leavitt via cctalk]

All this talk about computer cassette data got me reminiscing.


Back in the late 80's and early 90's I worked programming remote Campbell 
Scientific data loggers for an environmental engineering group. The device 
could store well head data for several days and monitor 8 wells from one data 
logger. Field techs (like me) would go around the active sites and download the 
data from the units onto cassette tapes using a device like this:

https://www.ebay.com/itm/Vintage-Campbell-Scientific-Inc-C20-Cassette-Interface-/391956667276?hash=item5b42701b8c


Here's some technical info on the device: 
https://s.campbellsci.com/documents/us/product-brochures/b_c20.pdf


When we got back, the data would be read from cassette into VisiCalc on the 
TRS-80 model IIs we used.

Later I wrote a program to read the data into Microsoft multiplan running under 
Tandy Xenix. We'd plug the interface into a terminal aux port, open it for 
reading, then convert it into a SYLK layout.


Were there other devices that did data transport like that.

It's not that easy. It's a chicken and egg thing. You have to have the original 
keyboard to copy in the new z80ctl and related files, then wire up the 2000 
keyboard.

Here are the instructions, I have the install software as well as the 
instructions for changing the 68000 to a 68010 if anyone is interested.
README starts here

UNSUPPORTED SUPPORT FOR TANDY 2000 SERIES KEYBOARDS ON THE TANDY 16B/6000
  Z80 Control System  Version 3(121) and later
 18-Oct-87710185

The instructions and files enclosed in this area allow owners of
Tandy Model 16A, 16B and Tandy 6000 systems to use the keyboard that is
made for the Tandy 2000/1000 family as the console keyboard.

On most systems, word processors and other applications are typically
difficult to use because of the limited functionality of the standard
16B/6000 keyboard.  These changes will allow you to use the console
to its full potential.  It will become a workstation people will
want to use.


THE DISCLAIMER

At this time, these modifications ARE NOT officially supported or
approved by Tandy Corporation or Radio Shack.   The contents of
this tar file are provided "as is", without any warranty of any
kind.  It is entirely the responsibility of the user to determine
whether these files should be used with the users' system.   The user
shall make any adjustments or corrections necessary to use these materials.
By providing these materials, it should be understood that there is
no commitment of any kind to provide these materials in a supported form
in the future.

When reporting problems with your system or obtaining service, make sure
the problem persists when running with the standard release of the
operating system and the standard keyboard.  Problems that occur when
using the items in this tar archive may not be responded to and may not
be corrected.

The modifications have been heavily used on the systems used by the
XENIX System Programmers and other systems with few problems.  (Some
application software does not like the code sequences generated by the
arrow keys.)  Since no hardware modifications need to be made to the existing
keyboard or computer,  you can easily switch to the stock 3.2.0 operating
system if you suspect a problem, or when taking your system in for service.


HOW IT WORKS

Both the original 16B/6000 and the 2000 keyboard use a serial transmission
method, where the data is sent to the computer via a data and clock signal.
The 16B/6000 keyboard produces 8 bit ASCII characters, and sets the
high bit on some characters to increase the number of codes.
The 2000 keyboard produces 8 bit scan codes, generating one code when the
key is pressed and one when it is released.  Most keys also repeat
the "press" scan code if they are held down long enough.  It is up to
software to translate the scan code into a character, and to keep track
of the SHIFT, CTRL and ALT keys, changing the generated character accordingly.

Because the electrical interfaces are almost identical, the only thing
that prevents the 2000 keyboard from being used is the extra software that
is required to generate ASCII from the scan codes.

Starting with z80ctl 3(122), which is included in this area, the software
necessary to operate both the 16A/16B/6000 and the 2000 keyboards is
included.


To make XENIX easier to use with the new keyboard and keep compatibility
with the old keyboards is a complicated task.


MAKING IT ALL WORK REQUIRES SOME HELP

When you reach the Xenix Boot> prompt, a decision is made as to what type
of keyboard you have.  At this point, the first key pressed is of a
small group, and the system uses this to determine
what type of keyboard you have.  If you press some other key as the
first key, the system may ignore that key or select the wrong
keyboard type.  This is because some scan codes look exactly like normal
ASCII characters, and the boot track can make a mistake and select
the wrong keyboard type. If this happens, press RESET and try again, this
time avoiding pressing one of the "collision" keys.
The keys that the system "expects" as the first key struck are:
d  h  x  z

If you have autobooting enabled, then it is possible that no key will be
pressed when the system reboots.  When this happens, the boot code first
looks to see if z80ctl left the keyboard type in memory from the last time
it was running.  (This is always true after a shutdown, and usually
true after a crash.)  If there has been a power failure or some other
program has been run (like diskutil), this information may not
be present.  In that case, the boot track selects the default keyboard
type by looking on the hard disk.  This value is set to Model
