Vintage Synth Repair

Hi, I'm new to the group. Back in the late 80's I used to repair
Roland D-50's, S-50's and other  models, plus equipment from other
brands like Alesis, Boss, Yamaha, Korg, and others. We also where the
out of house service shop for an authorized Roland distributor, so
they usually used to order quite a few spares and passed them on to us.

Anyway, while cleaning the shop I found in a drawer a whole lot of
mostly NOS D-50 (and for a few other models) chips (CPUs, ROMs, RAM,
Gate Arrays, DACs, etc) plus some other parts. These have been sitting
forgotten and well protected in this drawer for 20+ years and where
just recently rediscovered.

So if anyone might be interested please visit my web page where I
published the list (which you can also download there as an Excel
sheet, CSV, or Text file). Incidentally the list was just updated
today as a few additional parts that where found and added.

I was initially thinking of selling these parts through ebay, but
decided it would require a lot of effort, and also decided I wanted to
offer them first at a few Roland enthusiast forums and groups, to give
members a chance first, and in hope that the parts will possibly help
resurrect cherished vintage gear that has been forced to gather dust
for some time now.

As expected some parts have already been sold, so if you're in need of
any of these either for a repair, or maybe just to stock up for future
needs, please let me know. I have no idea (so far haven't done any
market research) on the fair value for any of these parts, so I
haven't set any selling prices yet. I'm open to (hopefully) fair
suggestions. Might also consider selling the whole lot as a package
deal if anyone would be interested.

Please feel free to ask any questions about the parts either posting
them here so other could also benefit from my answers, or via direct
email preferably to the address specified at a web page specifically
setup for the parts and located here:

There I also posted general pics of most parts, but I'll be more than
happy to send any interested party pictures of any particular part(s)
upon request.

Thanks for having me here.
