And just what computer can this work with (old >Apple, XT, Atari?) Not CR800, CMU-800. The CR800 was a black wedge-shaped box that was one of Roland's last preprogrammed rhythm boxes. The CMU-800, though, ahhhh, now *that* is another story entirely!! The CMU-800 is a medium-sized, off-cream metallic wedge, with a barrage of jacks on the back and a bare minimum of knobs on the front. It also sported this ruddy great ribbon cable hanging out the back! What is it? Essentially, its a computer-controlled CV/gate output system, designed to work with three computers - a Japan-market-only NEC Z80 machine, the humble Apple II range, and (of all things!) the IBM PCjr. No MIDI, no inputs as such, just a means to let your "brand spanking new 8-bit computing marvel" be the controlling heart of your System 100M. The box was the same for each model, you just bought the interface and software to suit your particular CPU. Imagine an MC-4 sequencer. Now take away all the smarts. Coming close :-). Because a lot of people didn't *have* 8 channels of VCO-VCF-VCA to play with, Roland provided 5 'channels' with incredibly simplistic monosynths that made the same horrid "paaaank" noise. Ghastly things :-) Fun, though, at the time -- I could plug one into my Apple II and make the most horrendously sounding Bachian diddle-doddle noises :-). I think I still have the circuit diag and some software for the Apple II version of the interface ... somwhere in the bowels of my aging A2 floppy collection! Geoffrey Really?
