its prolly a pc-5000 pc-50 pc-60 pc-600. Do a search on them on here and you'll see. They're not much more than a boat anchor. I've owned a pc-50 and a pc-600. I made some money with the pc-600 until i had to send it out to get the print head replaced $600.00+. These machines are the reason that I now own a versacamm.
But....if the machine is in good working order, comes with ink cartridges, and you can buy it for less than like $2000.00...it MIGHT be worth your while.
Otherwise just save your money and buy something thats not gonna give you a bunch of headaches.
