Challenger 4P-MF

I have a 4P-MF with the 48K expansion board which has been in storage for many years, but seems to run as floppy drive cycles. I do not have a way to check video and thus actual operation. I have a great deal of documentation and some floppies for it as well. Will provide photos on request of everything.
Am downsizing so shipping and a reasonable offer is all I am expecting. Have original shipping box to go with it and a joystick. Live in NH if that is reasonable driving distance.

Thank you for consideration

Hi Ed,

Could you provide some images of the case and internal boards? Does the equipment include the original 5" drive and/or any other OSI accessories? Last question: what is the 48K expansion board -- is it an OSI board or third-party supplier?

Many thanks, Tom

Hi Ed,

I'd be happy to discuss a fair price for the C4P-MF equipment and software! Tom Blum

Is this C4P still available? I am very interested in getting my hands on this.
