I'm looking around to see if there is a cheap evaluation board that could help me learn Motorola assembly that will then enable me to do some re coding, understand hacs etc.

What do you CodeOphiles think about this?

At NZD 139 (that's about USD 70) for the CPU board plus the development board and the software, that doesn't seem like bad value.

I'm looking for something that allows a serial link to my PC with "lights and buzzers" to turn on and off with the HC11 code so I can learn hands on. Is this the right place to start?

Any other suggestions on tools that might be better value or a better place to start?

Programs can be easily compiled and downloaded directly onto the board, allowing rapid application development. Board is suitable for use with a number of compilers and is a great learning tool for the 68HC11 series.
The 68HC11 Development Board includes 24kByte of program memory, stored on board in the AT29C010 flash eeprom. A further 32kByte of RAM is provided in the 62256 on board RAM chip. 40 Bit I/O is provided via the 8255 port. Expansion sockets are also provided for a Z80 bus expansion. 8 bit, 8 Ch A/D is provided on the 68HC11 IC, a socket is also provided for the fitting of a M6242B real time clock.

Connections are pre-wired and fitted with terminals for an RS232 Connection, RS422/RS485, SPI, LCD, Keyboard and timers.

Please note: This is a complete unit and not a kit. Power supply is not included, a 12V dc power supply can be used for the unit. The RS422/RS485 requires two 75176, not included in the basic version.

Features
• 24kByte Flash Program Memory
• 32kByte On-Board RAM
• Easy to Download and Test Programs
• Great learning tool for the 68HC11 Microcontroller Series
• RS232 Port Provided On Board
Special Introductory Price of USD$65.00

One thing you need right away is an ecm bench. Even then things can slip by you. But at least you can get past the flashing CE light.

I've bought 2 developement boards, and a serious robotic toy, and abandoned them all out of frustration.

My current strategy is just bombarding myself with the snippets of stuff I've found on the net, and trying to edit that into actual source code.

To have really meaningful source code also means even having the RAM locations the processor uses, and I to this day have no clue how guys figure that end out.

It is really addictive, and usually fun, but it can be a long road.

 

i know what you mean.
