+rc2014-compat
+=============
+
+A respin of the [RC2014](https://rc2014.co.uk/) ecosystem.  I don't have any
+opposition to building things out of SMD parts (in some ways, I find it
+easier to work with), so some boards might go that way to the extent that
+parts availability allows.  Also, I'd like to keep all board sizes within
+the 100x100mm limit within which PCB fabs offer their cheapest rates (like
+$2 double-sided at JLCPCB, for instance).
+
+68b50-dual-serial
+-----------------
+
+Two serial ports, one card.  One is connected to the TX/RX lines of the
+backplane for a TTL-level console port, while the other drives a 9-pin
+serial port through a MAX232 to control printers, modems, and other RS-232
+devices.  Bitrates of 115.2, 38.4, 19.2, and 9.6 kbps are independently
+selectable with jumpers, and by using the 6850's internal bitrate divider,
+rates down to 300 bps can be set up if needed.  The card's base I/O address
+is also jumper-selectable.
+
+This board has its own 7.3728-MHz crystal oscillator, making it independent
+of CPU speed.  (I'm aiming for 10 MHz with both of my CPU boards.)
