Yamaha U-100

Not much is documented about the Yamaha U-100. The only period reference in the archive is a short item in Audio (October 1999, p.19). It calls the unit the RP-U100 and files it under "personal computer receiver" - a home-entertainment receiver built to work with a Windows 98 PC over a USB connection. The category was short-lived.

Per that report, the U-100 had an analog A/V input with composite video, three analog audio inputs, and a discrete six-channel analog input for future multichannel formats. It carried five internal low-feedback amplifiers, rated at 70 watts.

That is nearly all that survives. No production years, original price, dimensions, or full specification sheet are documented. The review calls it the RP-U100, so the exact model designation is a little uncertain. No other period coverage has surfaced.
