I came across an odd board in the dumpster at work today. Hopefully
one of you might recognize it. It appears to be some sort of bubble
memory board.

Details:

        Small board, approx. the size of a 5.25" floppy drive board
        2x40-pin Berg headers at one end
        2x36-pin edge connectors at the other
        2 very small pushbuttons
        3 LEDs labelled:
                ERR
                EN
                RUN
        Obvious chips:
                ROM labelled "RCB1.1"
                Z80A
                Intel D7220-1
                Intel 7110A-1 bubble memory module
                Lots of 74LS-family chips
        Markings:
                Bubbl-tec
                division of PC/M, Inc.
