A little bit of History
Since there are some evaluation versions out there I decided to add this page with the firmware revision numbers where some new functionality was introduced.
0.34 Allow comments after an instruction
0.39 Port Wide IO through PORT keyword and PORT0, PORT1 commands
0.43 Changed Autorun and and Ctrl-C during autorun behavior
0.44 Changed Ctrl-C in autorun to force a reset
0.45 Changed Random Number Generator to TinyMT
0.46 Max Identifier length changed to 24 from 11 and allow _ in identifiers
0.47 Changed Single Step behavior to print the line to be executed
0.49 Added Pin14 as Valid IO pin for new PCB
0.50 Allow editing of time while entering the date/time
0.51 Added MIN and MAX keywords
0.52 Added WHILE/WEND loop
0.55 Added PULSIN, PULSOUT instructions
0.56 Added SSTEP, the breakpoint instruction

Three Versions of EzSBC1
The version on the left was the first miniaturized version of the EZSBC1and it needed a jumper to function. Only five PCB's were ordered and three were populated and tested. This is the very first one assembled, by hand.
The version in the center was a shrink of the first version with the PCB size reduced, a much smaller Reset button. This is the first one built. The design is ROHS compliant and all components except the RTC crystal is surface mounted. 120 PCB's were delivered and about 60 were populated, mostly with a pick and place machine. None were sold and all but two were given to people who asked to evaluate the EzSBC1. The only requests about the hardware was that the Reset button is maybe too small and RTC crystal may limit the reliability under high vibration.
The right hand board is the final design. It is completely surface mount, rugged and has a larger Reset button. Pin 14 was spare on the first two versions but is now available as an IO-pin.
The price is $49 for singles with free shipping in the USA.
