The 600 had a console with 2 black & white monitors built in, as well as a light pen used to control the system.
It recorded and played back black-and-white "skip-field" video in analog on specially modified disk pack drives (supplied by Memorex, and which were commonly used to store data digitally on mainframe computers of the time) that were the size of washing machines.
This audio was somewhat poor, due to a large amount of jitter occurring from the signal being played back from the disk packs.
The CMX 600 could support up to six disk pack drives, for a total recording time of 27 minutes.
The CMX 600 was a system quite ahead of the technology of the time, and was quite expensive, costing about $250,000 USD at its introduction.
