2 Kits set for shipping on August 8th
We had
some problems getting the pc boards done correctly, and then we discovered
that the chip vendor (Ubicom) changed the silicon in some way that caused
the chip+resonator not to oscillate ... arrggghhhh !?$#@! We've
worked the problems out with Ubicom and we're in the final stages of
programming everyone's SX microcontroller chip. We will get the kits
into the mail this coming week and we apologize for the delays in getting
them to you. At least they'll work nicely, as expected. Also,
check out the latest schematic, layout, software and manual on the main
web page, as this all describes what you'll be getting as well as the
serial port features.

Pin Mix-up (only in "version 1"
Manhattan-style kit used at Atlanticon)
In the
final stages of software development we swapped a few of the Input and
Output pins on the SX microcontroller ... and forgot to update the
schematic!! This is a classic hardware-vs-software documentation
error <sigh>. Anyway, it's not a big deal but it could cause
some confusion.
The affected pins and functions are listed below:
PTT output --------------- was
pin 7 -- now pin 8
Test Point output -------- was pin 8 -- now pin 7
START Pushbutton input --- was pin 25 -- now pin 24
CONTINUOUS Jumper input -- was pin 24 -- now pint 25
