Tektronix 4225 -- is it an X terminal?

I wondered at first if it was indeed a complete UTek-capable UNIX box but intended to run an external disk (most of the XD88's case height is due to the full-height drives inside) - but the lack of a obvious disk port (it'd logically have a Centronics SCSI port where the "computer" label is) suggests that isn't the case. It could, I suppose, be designed to boot and run solely from an OS image on a remote system via the Ethernet port. It might also contain a HH hard drive inside; if the XD88 had HH drives the guts could probably just be squeezed into a case that size. The fact that it has a local floppy drive and RS232 ports suggests to me that it's more than a mere X term anyway (but then Tek did do some pretty complicated terminals back in the day) - plus my XD88 is circa 1988 and very soon after that slimline X terminals existed in abundance, so I'm not sure what this particular critter would have to offer if it's just a big X term with local floppy storage. Shame it's so far away or I think I'd be putting in my first ever EBay bid :-) I'd love to see an inside pic of it. cheers Jules
