Large vintage Psion collection (Revo, Sienna)

Large vintage Psion collection:

Psion Revo (8MB): 6x 8MB Psion Revo unit's. All need batteries, only one of them will power up currently. The others did work in the past, most of them do not have batteries in at all anymore, there are two loose battery packs but they are very old. I do not think all the units have the required battery plugs etc to rebuild the pack easily (these are soldered AAA size nimh batteries). Some of these units have the cover coming loose, possibly broken. Only one still has the stylus (the one which powered up). 3x spare screens also included, they are unused as far as I know, untested. Also one original manual for the Revo.

Revo dock: 2x docks for the Revo's, look to be in perfect condition.

Psion Sienna: 2x Sienna's one is the 1MB model and the other the 512KB. Both are working. The 1MB model is cosmetically in the better condition. The 512kb model display is a faulty as it has lines running through it when powered up. Both require batteries (they use regular AAA).

Psion series 3a: There is 1 series 3a however it is in bad shape, repairs have been attempted and the screen is very all cracked and damaged looking.

Networking items: There is a collection of Psion network items and interfaces, various floppies with software and manuals.

Modems: A very large collection of Psion portable infrared modem units, some are in pouches, also many power supplies. The power supplies also work for the Revo units. The modems are untested. At least one power supply is working, some may be dead, mostly untested.

Software: 3x software packages: Chess, Expense tracker and Monopoly. The Chess program is a card type unit that plugs into the 3a or the card reader interface (included). The other 2 are on 3.5" floppy disks. All untested.
