        I have an unidentified Q-Bus board that I'm hoping someone will
recognize. it's a quad-height (i.e. full-size) board. On the component
side is says "RELIABILITY ASSOCIATES" and (c) 1987 and "TIME SLOT
CONTROLLER". It has two 40-pin headers and a 20-pin header and two
pushbutton switches. Chipwise, it's got a 68000RC10, a couple of 68450s,
three MK68564s, and a 74S409N, all socketed, and a host of PALs and MSI/SSI
chips.

        Anybody know what this is? Also does anyone have data sheets for 74S409?
