tnylpo allows the execution of programs written for CP/M-80 version
2.2 under Unixy operating systems. It has been tested under Linux
(Debian 8 i386; Debian 9 amd64; Debian 10 amd64, i386; Ubuntu 18.04.1
LTS amd64; CentOS 7; Slackware 14.2 i386), FreeBSD (12.0 amd64),
NetBSD (9.0 amd64; 8.0 i386, sparc, vax), OpenBSD (6.4, 6.7 i386),
Solaris (10 x86, 32 and 64 bit; 9 sparc, 32 bit; 9 x86; 7 sparc, 32
bit), and Mac OS X (10.5 ppc, 10.6, 10.9, 10.11, 10.13), but should
need little to no modifications to run under any other reasonably
recent system. The companion program tnylpo-convert converts text
files to and from the CP/M format.
