Rosscomp tape drive.

This probably the only one of these around now.  At one point, I think Sanyo (Sangyo in Japan) took over Rosscomp and a smaller 5 1/4" drive.  I don't have one of those.  This one was the last US assembled drive and was a proprietary interface.  Also it was an 8" short form factor.

The 5 1/4 drives made by Sanyo had a SCSI interface, but were stillborn, too late, and the contractors couldn't make the firmware work.

Here are a couple of LA times articles from 1985 when Rosscomp was circling the drain, and started to sell off parts of itself.

Article mentioning the president of the company at the time, Rod Hosilyk.

S 100 board load for a Friday night

I bought a Vista Card some weeks ago, and need to figure out what it is.  Main reason for it was that it was made here in Santa Ana, CA and Vista was bought out by Dave and Tom Freeman and operated with Advanced Computer Products for a long time.

Steve who had these boards had a bunch of other boards, and I bought most of the Compupro / Godbout stuff he had.  Also there was a Tarbell Double Density floppy controller.

And for good measure there was an SA-1000 / ST506 controller which will be fun if I can get it running with Dave Geswein's 506 emulator.  Will be a whole new dimension on S100 computing.
