” Note: I’ve checked this over 12/3/2015 and tested it with a Synclavier II mini-system, all the switches are working properly and everything has tested good. It has only the slightest scuff on one corner of the case, too small to even see in a photograph. It is absolutely as new.
This is the rarest and most sought after piece of Synclavier hardware, the HOP hand-operated processor. Originally designed for internal company use debugging new software and designing new interface cards, it later proved to be indispensable for anyone trying to maintain Synclaviers and troubleshoot Synclavier problems. Any Synclavier technician must have one of these at all times. TRY2FIND1.
Perfect condition, tested today and working perfectly, no broken switches.
Includes the control box with built-in cable, and the special interface card that plugs into the computer bin of the Synclavier.
Using this hardware is always the first step to take in trying to start a dead Synclavier system that has been sitting unused for many years, and even more so for a Synclavier II to that does not have a Macintosh or terminal display. The light activity on the LED panel always assists me greatly in knowing what the floppy drive is doing, what the Winchester drive is doing, and what brain activity there is going on inside the system, if any at all. That usually leads me to give attention to some physical piece of hardware, such as physical connections, looking for broken wires, loose or corroded connectors, or power supply issues. Beyond that, it gives me the crash codes so I know what card might be causing the problem and should be swapped as the next step and getting the system going again. If someone comes to hire me to fix a dead system from far away, if they have one of these units, it can provide me with a lot more information remotely, possibly preventing the need to ship the system to Los Angeles for a hands-on repair.
One of the photos shows the unit and the built-in cable and the interface card and user manual, and the other photo shows the way the unit is actually used, with the interface card inserted in an empty slot in the computer bin of an upgraded Synclavier II.” Link
