Inside the Prototype Alesis 6461 QS6

Here are ome pics of the inside of the prototype Alesis 6461 QS6 posted here, in via Mike. These pics have been added to that post as well.

Per Mike: "Looks like a 'nearly production' version as I see only 2 hand soldered jumper cables. Everything else looks neat. Even the PCMCIA card slot is there, even though there is no external plastic guide/surround."

Note the ALESIS S6 MAIN PCB REV. x5 dated 5-23-95 printed on the PCB in the 2nd to last image below, followed by a sticker found inside dated 9-5-95. It likely fell off a chip.

The QS6 was released in 1996, per Wikipedia: "In 1996, Alesis introduced the first of their QS series synthesizers. The first of these were the QS6 61-key synth and the QSR rackmount synth. Following these in quick succession were the QS7 76-key synth and the QS8 88-key synth"

Update via Mike: "Info from one of the original Alesis engineers around the time says that this was the only prototype made. They had done tests 'out of the box' but only 1 physical 6461 was made."
