Oberheim Cassette Interface

via this auction.

Details:
"I have only seen 3 of this unit in my 20 years playing synths. Its very rare, and Vintage. Its the Cass-1 Interface for the OB-1 and the 4, 6, 8 Voice SEM synthesizers. Its the only way to load, save sounds into the memories of these synths. It also has check errors for the sound memorries. I dont have my 4 Voice any more so I am selling this unit. I cant test it , as I sold my 4 voice so its as is. It worked fine when I had my 4 voice. I have a copy of the manual that I will send with it. The Cass-1 came out in 1978 from Oberheim. I have only seen 3 unit total, and have never seen one on Ebay. A must if you have a 4, 6, 8 voice Oberheim. I payed $500 and it was worth every penny."

Korg Poly 800 Update

"The Korg Poly 800 and its EX 800 companion module were great synthesizers for their time. I've owned several over the years. But their MIDI implementation is very short on features. Furthermore, there are several features that are just plain missing and on top of that, there are some excellent modifications that people have been doing that require drilling holes in your treasured keyboard. This I hope to change by disassembling the original software and perhaps designing and then short batch manufacturing a retrofit kit whereby we increase the total memory (both RAM and ROM) and thus provide the additional features via the original 80C85 processor.

The basic idea is going to be to add additional ROM and RAM. We'll make sure that the instrument can be booted up in its original configuration using its original software. But, when you want to access the new features, you will boot the instrumnet up into the new ROM's and RAM.

We may also provide some additional interface chips that are able to integrate some of the well known modifications into the new software. This will make the mod's more useful and programmable rather than having to drill holes in your keyboard to fit new knobs or switches."
