1983 Boss DR-110 Dr. Rhythm Graphic Drum Machine Brochure

via Retro Synth Ads where you'll find the write-up.

"Boss DR-110 Dr. Rhythm Graphic drum machine 'A sound Innovator' four-page colour brochure from December 1983."

Note the above image is the inside of the brochure. The cover is much brighter.

Inside a Kawai R100 & the Drumware Inc. Soundswitcher

Some pics in via GrantB of the Music Technologies Group Blog. Click here or here for what an R100 looks like on the outside. There have only been two previous posts on the Kawai R100 Drum Machine and only two on Drumware, one featuring an Oberheim DX Drum Machine, and one a Sequential Circuits Drumtraks.

"Here are some photos of the ROM switcher board in my Kawai R-100 Drum machine. The expansion board is dated 1987. My unit contains three 4Mbit mask ROMs:

MN234000KAA, MN234000KAB, MN234000KAC

I think these ROMs are the original R100 and R50 and the R50e judging by what I’ve read elsewhere on the web. The sound format is 12-bit (non-linear) with a 32kHz sample rate."
