ISO: Tektronix 4404 peripherals

Hi all -- I'm working on fixing up a Tektronix 4404 workstation (runs Smalltalk-80!).? Or rather, I'm trying to collect the needed parts to assemble a complete system so that I might fix up said system -- at the moment I have only the main CPU unit (but hey, it's a good starting point).? I am looking for: - Keyboard (Tektronix P/N 119-1872-00) - Mouse (Logitech P7-3F-TX-19-1808-00).? This is likely a standard 3-button quadrature mouse but if I can find the exact match, so much the better... - Mass Storage (Tektronix model 4944, possibly others?? This is a SCSI device containing a hard drive on a SCSI->MFM bridge and 5.25" floppy drive on a custom SCSI->floppy interface.) If anyone happens to have spares or knows anyone who might, please let me know.? Thanks as always! - Josh
