Subject: TRS-80 Emulators

There is a TRS-80 Model III emulator called PC-THree available from
Hypersoft, PO Box 51155, Raleigh, NC 27609. This emulates the entire
machine, and provides a disk transfer program which creates 'filedisks'
on your MS-DOS hard disk from which TRS-80 operating systems and 
application software can be run. It works quite well, although the
graphics emulation leaves a lot to be desired. It will drive the PC's
serial port and a printer attached to the PC. There is no emulation
of the cassette port (and therefore no sound emulation). You really need
an AT or above to run it efficiently - otherwise the keyboard driver tends
to lose characters.

Since the model III emulates the Model I to a large extent, you can run
much Model I software on a MS_DOS PC under Pc-Three.

Hypersoft also produce PC-FOUR, which emulates the Model 4 in native mode
only. I'm not sure if it also emulates the LS-DOS operating system or
if you have to copy that to a 'filedisk' as with Pc-Three. Pc-four
will not emulate a Model 4 running CP/M.

I should be glad to know if any of the rumours of public-domain
emulators can be substantiated.
