Value of Altair 8800b

[David Williams]

Trying to figure out a fair value for the following:

Altair 8800b with two Altair floppy drives. System is clean but hasn't 
been turned on since the 70s. No software or manuals available. Contains 
the follow boards:

1 CPU
2 Floppy disk controller
3 MITS 16k dynamic memory boards (48k ram total)
1 MITS 8800 Disk BD1 Rev 0 x4
1 SIO board with 2 serial ports
1 MITS 8800 PMC Rev01 2k Prom Board

Can reply off list.

Thanks.
