In my second year of TAFE, quite a while after I completed the Microprocessor Fundamentals module, they decided to upgrade from the MEK6802D5 systems to these units. At the time, and still now I'd say, 68HC11 development boards from Motorola cost a fair bit and were out of reach of the average students budget. Dennis, our head of department, designed this board as a solution and it was sold to students as a kit for a measly AU$60.
Even though I had previously completed the aforementioned module, I decided to repeat it just as an excuse to buy the board. Basically, the 68HC11 is a 6800 with an extra index register and the ability to combine the two 8-bit accumulators to form a single 16-bit one. It also has onboard ROM and RAM as well as inbuilt peripherals like timers, A/D conversion, RS-232, parallel ports, etc. Now you can understand why I wanted one, eh?
