Help with recognising the make and model of a cutting plotter

[Protazy]

Hi guys, wondering if you can help me. My mate has a cutting plotter like shown on the phote. It seems to be a quite old one, on a side it's got only RS232 port, no USB. There is no make and no model mentioned anywhere. Is any of you able to regognise it? any idea if it can be connected via RS232 to USB converter to a Windows 8/10 PC and what software is recommended for it? it seems to have very similar casings to a colorsun model JK720.

Any help appreciated
Cheers
Pawel
