Range
[edit | edit source]The CF-3000 has no space inside for a floppy disk drive.[1] National's MSX1 range also included the one-piece CF-2700, CF-1200 and FS-1300, which share a case, and the CF-3300, which has a built-in floppy drive.[3]
Servicing
[edit | edit source]The MSX Resource Center's page has photographs of the inside of the main unit and of the keyboard. No Matsushita service manual for the CF-3000 is among the MSX service manuals held by the MSX Archive.[1][4] For general advice on capacitors see Capacitor Failure Symptoms.
