Ian Burkinshaw Hardware Documents

Hardware Projects Page

What follows are hardware based projects written by Ian Burkinshaw for QL Today over the last 5 years. Ian limits himself mainly to projects that use either the SER ports or PAR ports. So his projects can be used with both Black Box QL's and emulators. In the case of emulators USB ports are used in SER mode. So standard USB to RS232 converters are used. In the case of PIC Microcontroller projects either RS232 or USB simulating a RS232 port is used. By not delving inside the QL itself, there is less risk of damage to QL hardware. However this is all done at your own risk. There has been some editing and corrections made to these articles, in some cases to just update things. Nothing major, so the articles are pretty much as they were printed originally. Project and articles will be added over time. These will all be new and will not have appeared in print before. So do keep an eye out for new projects.
