This is a great example in really clean condition. Privately owned so no grubby school kids have been at at!! The power supply was replaced early in it's life and a third party non RIFA cap PSU was put in it's place. It has been previously upgraded and has reset, rs423, user port and disk drive ports installed. serial is cleartone 101577. powers up and works, i've run a few programmes and all is working well. I haven't test any other ports other than uhf/rf. comes with 3 programming books and the user manual.
