  * Interesting that it's "Symwar" on the KERNAL IC, and SYMAR on the
    daughtercard 2732
  * The 26 ICs confuses me.  I was guessing DRAM, but 26 seems an
    interesting number (256kb *4 * 26 = 3.4MB)
  * 2 6551s and associated drivers are onboard.  That will potentially
    make it hard to determine use, as it no doubt integrated with a dual
    UART type device (or two devices)
