Personal Mini PM/4T

The Mini PM/4T was the multi-user version of the Televideo PC compatible. A video terminal was used for interfacing directly to the system.

The InfoShare Operating System can run many multi-user programs or execute most single-user MS-DOS programs.

The PM/4T can be linked to up to four computers (PCs or Televideo's PM Workstation [a terminal]).

It was sold for $6000, and a 16-user version was available at $9000.
A $99 card was required to connect each PC to the system.

Igor Pronin reports :
I was one of the first users in Finland. Infoshare Operating System was actually Novell Netware. In the begining it was version 1 or 1.1 but it was soon upgraded to 1.2. As a server running programs off the server, it was faster than from a local hard disk of a 12 MHz AT.

Please consider donating your old computer / videogame system to or one of our partners from anywhere in the world (Europe, America, Asia, etc.).


The TeleVideo PM4 was one of the first dedicated fileservers. It could serve up to 4 IBM (compatible) Pc''s.
As a server running infoshare (indeed the earliest version of Novell) is could handle record and file locking.

I know because, as technical support manager at that time, I introduced this system in Middle and Northern Europe.

have a nice day

Came across this site- great. Sold over $10MM of Televideo-INFOSHARE (aka NOVELL) in Canada- few believe me when I tell them that infoshare 1.0 was the original NOVELL! Also sold 1,000 ALTOS Xenix/Unix CPU's a few years later- another great system!(from Dave Jackson-ex Dec) good luck! Stu

I recently picked up a pm/16t I believe. Haven't tested it yet, came with a few disks. Hope I'll be able to image them properly. E-mail me if you have one or whatever. Better yet join the yahoo group.
