     This disk contains the files necessary to construct and install an
SBIOS for the Jonos Escort portable computer.  This SBIOS is suitable
for use with SofTech MicroSystems UCSD Pascal, Version IV.1 (UCSD
Pascal and p-System are registered trademarks of the Regents of the
University of California).  In addition to the basic SBIOS files, it
contains the text of a program to format the SONY 3.5" single sided
disks which the Escort uses, and one side of a file transfer program
which can be used to exchange Pascal files through one of the serial
ports at up to 9600 bits per second.

     The accompanying program material material is copyrighted.
Permission is hereby granted for the free private use and modification
of the programs on this disk by any members of USUS or their associates
for any non-commercial use only.

     The disk contains text files for the SBIOS, the installation
program (bootmaker), the disk formatting program (formatter), the serial
port transfer program (trans-mgr), and miscellaneous supporting programs
and units which these programs need to operate.  In addition, it
contains assembled versions of the bootstrap and SBIOS code, suitable
for installation on a disk as described below.

     Each program on this disk can be assembled and/or compiled using an
appropriate redirection file.  The names of all redirection files end in
'-genr.text'.

     The suite of programs is sufficient to install the p-System on an
Escort once a working system disk is available for that machine;
however, it does not contain a method for transferring the files from a
p-System to the Escort to begin with.  A simple serial port transfer can
be constructed under CP/M (which comes with the Escort) (CP/M is a
registered trademark of Digital Research) to get the load files
installed on track 0 to begin with.  I suggest that the bootstrap (file
'E.LOAD.BOOT' on this disk) be installed in sector 1, the secondary
bootstrap (which you must extract from your SMS distribution disk) be
installed in sectors 2-5, and the SBIOS itself (file 'E.LOAD.BIOS' on
this disk) be installed in sectors 6-9.

     The code may be well enough documented internally so that it is
clear to an experienced Z80 assembly language programmer with access to
the SofTech Adaptable System "Installation Guide" and the IV.1
supplementary documentation.  I simply do not have time to write a more
thorough explanation of the code, or how to use it.

     Good luck with your installation!
