Hmm, I don't seem to have anything helpful, sadly. One of my XD88-related 
scans mentions "4300 and 4200 series workstations and netstations", but all 
that implies is that the 4225 was earlier. Reading between the lines, it seems 
that the 4225 runs on something other than an m88k.

Some Google results seem to imply that the 4225 is "just a graphical 
terminal", and not even a full-fledged X terminal at that.

I don't think there's mention of a keyboard in that auction is there? That 
might be problematic - although the socket's the same as the XD88 family one 
(and, I think, some of Tek's earlier terminals) so it may be that there was 
some commonality across models.

All this makes me realise just how much Tek knowledge seems to be a lost - I 
mean, the earlier Tek terminals seem to be pretty well understood, but then 
most of the hardware, software and docs from the later years has just vanished.
