"Included in the auction of this legendary synthesizer:
- A brand new Roland Boss 100V-240V power supply, meaning that a stepdown transformer is not required outside of Japan, and you’ll be able to plug in and start working as soon as you get the unit. An appropriate plug adaptor will be supplied if required.
- An original Roland leather strap in mint condition.
- An original Japanese/English user’s manual. This includes illustrated parameter settings for producing a multitude of various sounds, which will high light the SH-101 as being more than just a wicked bass machine."

Sequential Circuits Owned Prophet T8 SN 000008 Property Tag 1935
Note: links to listings are affiliate links for which the site may be compensated.

via this auction
via the listing: "This is a time capsule piece. This particular T-8 was not sold through a store. THIS T-8 was owned by 'Sequential Circuits' personally (see the foto of the property tag). This particular unit (serial number 8) has a pre-production Main board that was modified to release specs by Sequential (see photo). All mods and updates were performed by Dave Smith and crew.
According to an ex-engineer from SC, this T-8 has all of the latest firmware revs. It has been fully tested and is fully functional. The aftertouch on a couple of the keys is a bit touchy, but that's to be expected after more than 30 years!
I bought this unit directly from SCI when they were bought out by Yamaha. I never used it on gigs. I only used it (mostly) as a controller in my smoke-free studio. As you know, this keyboard plays amazing and was adopted by none other than the New England Digital/Synclavier people for all of their keyboards.
I have never had any issues with this keyboard, It plays super great. Included are about 25 extra hammer mechanisms, as aparently some of the heavier players would break a key now and then; but I never did."
