I have compiled some useful information on the OPD / Tonto, which can be found on the QUANTA web site.
QUANTA supports QL and related systems, and I am responsible for maintaining the societies web site. If anyone would like to donate their OPD / Tonto to QUANTA, or would like to support, documentation or advice, please get in touch.
We can offer a small sum for surplus OPD / Tonto hardware and accessories, which we donate to the Red Cross. We are trying to establish an OPD / Tonto support network, so that enthusiasts can swap software, trade hardware and keep this machine alive.
We are in the process of scanning in manuals and documentation for the OPD, establishing an OPD software library and list of frequently asked questions (FAQs). FAQs will include : where to obtain OPD software, tips for repairing damaged monitors, suggestions for troubleshooting hardware faults and advice on exchanging files with a PC or Sinclair QL
