It could be any of the following (at least): 4006 4012 4014 4051 4052 4054 4052A 4054A I'd guess it's not a 4014 or 4054 (A or otherwise), since these are not in the least "little" However 4052s of any flavour are EXTREMELY RARE. AFAIK, the only two known still to exist are mine and the one in the computer museum in Amsterdam, Netherlands. (If anyone knows of another 4052 or 4054 please let me know!) All the TEK terminals of this date are interesting, partly because of the dead-end technology, viz. the storage tube. If it is more recent than storage tube TEKs, it may still be interesting... BTW, the 4050 series had computers tucked in the bottom of the terminals - a 6800 based micro in the 4051 and a 16 bit bitslice in the others. To give you an idea of value, I paid roughly $200 for my 4052, and I have been advised by Dr Dooijes at the Dutch museum to insure it for $3000. (NB he paid nothing for his). It looks like insurance for the VCF is going to cost another 100 pounds... Philip.
