	This directory contains a number of useful VT-180 utilities written
for the VT-180 (Robin). The only problem with all the nifty stuff in this
directory is that there are no provisions for transferring it to a stand-alone
VT-180. Here at BASD we have a file transfer utility written by Polygon
Associates which allows us to download files from the VT-180 to the VAX
(and vice-versa). Therefore, I am able to provide .HEX and .COM files, but
no means to upload them to your VT-180.
	I apologize for this inconvenience, but for those of you who are
resourceful, these files may be of some use.

.le;GIO - General purpose I/O routine that allows you to do direct output to
physical devices. There are two versions: a generic 8080 version which works
on a our patched version of VT-180 CP/M, and a native
Z80 version which has the capability of working on any VT-180.
	This is written in Micro-Soft Macro-80, but should be
convertable to any assembly language. The important parts are the physical
device address definitions.
.le;Flyer - A little game written in ASM. Should be loadable, runable, and
understandable as provided here.
	My first crack at CP/M ASM, so it is not a fantastic example of 8080
code.
.le;Othello - The ancient, but still nasty old game of OTHELLO. Originally
written by John Fedak of the U. of Penn. and submitted by Ira Winston to
DECUS. This version drives the VT-180 screen in the same manner as the VT-100
version included in this BASD DECUS submission, but does not have the
reqind capability.
	Alas, I can only provide the .COM file, since I compiled it it
Microsoft Fortran-80, which is a licensed product.
