Honeywell/Ultimate Level-6

This Honeywell Level-6 was sold through the Ultimate Corporation. Ultimate specialized in systems that used the Pick operating system. There were two implementations of the Pick operating system on the Level-6. One used the Writable Control Store to translate Reality virtual machine instructions into Level-6 instructions. The second used a dedicated 7X bit-slice processor board to run the Pick instructions and used the Level-6 processor for I/O. If two 7X processor boards were installed the system was a 15X.
