Lots of miscellaneous. But U might get a kick out of the Honeywell 440 front panel. Its the largest in my collection.
I don't remember whether the Pertec came from the TI-990/10, which has a Tape Controller or the PDP-11/34. The TI has a 6 foot cabinet and so does the 34. It is sitting in the 34's cabinet, but that may not be original; those memories are cloudy.
The HP 7974 is and was always standalone; it has the GPIB I/F.
The rollarounds are from DEC WPS278's or COS-3X0 office stuff. They have 2 RX-0's but could hold four; it have two of those. I found a VT-278 DecMate II that I had forgotten. I had more but reduced them to cards. I should hollow one out and put a QBus cage in the bottom.
I saw two more TU-56's [one half-unit?] and a fourth PDP-8E; there are two TU-55's in the PDP-12. With the 2 in the garage, that's @ least 6.
Again, 4th 8E: there are non-descript cages, some loose backplanes and cards everywhere. Somewhere, there should be a second 8M; one of the cages/front panels is part of an 8A.
The HP 115 belongs in my HP 1xx stack; that's about 1 half-dozen machines. It's more if I count the old 100 carcasses.
