Apple IIc Plus

The other day I was helping my parents clean out their attic and I found an Apple IIc Plus, Apple Imagewriter II, and an apple CRT monitor. All items work, but the monitor cuts out sometimes. Does anyone know how much one of these would run for?

If it has been stored for some time, check out the cables are okay and not crunched or kinked. If master disks were with it perhaps a format and install may do the trick.

Otherwise, depending where you are as your profile does not say, try eBay for a CRT. Have seen posts in Mac forums folk leaving them on the roadside for trash collection as they have no or little value.
