<pre>Yes, it had occurred to me too that it simply might not have been economic to mess about with it, even for a fairly simple fix. I don’t know what these things fetch(ed) but the CEMs were certainly worth plenty. If the outside was beat-up too, it might have looked impossible to make any sort of sense out of spending hours on it.
We’ll see, I guess.
Thanks for the documents - that’s a *lot* more than I had before.

But then, maybe it *did* have problems. Chris On Fri, 25 May 2018 15:07:57 +0100 Tom Wiltshire <<a href="mailto:tom@electricdruid.net">tom@electricdruid.net</a>> wrote:

Specifically, Iâm interested in how the voice Pitch CVs are generated. From the era, Iâm guessing DAC->4051->S&H, but I havenât even seen the main board, let alone the schematics, so itâs real guesswork. Iâm trying to help a customer debug one. Theyâve got one that was stripped of CEMs, so theyâve put Alfa chips in it. First thought was that the Alfa chips are either faulty or not totally compatible, but it doesnât look or sound like that to me. I suggested that there must have been a reason someone gave up on repairing it and stripped it of valuable parts, and that we should find that reason. Tom</blockquote>

This material is all in German and includes the MIDI instructions. The schematics are very casual and do not bother to describe things like decoupling and the specifics of the front panel & keyboard assembly. Still, everything is there that one would need. <a href="http://www.beatkamp.com/downloads.shtml">http://www.beatkamp.com/downloads.shtml</a> PS: I will shortly be hand building a MIDI board for my Banana. This involves a simple daughter board tethered to the Z80 CPU socket (the CPU moves to the daughter board). This also requires a new EPROM image (kindly provided by a helpful list member). I am particularly excited to try the Banana split mode where half the keyboard controls the inner synth and the other half, an external synth. Cool! Hope it works.</blockquote>
