Not sure if I can get a QL related thing involved in there yet, still thinking on that one.
Does anyone know of a simple i/o port I can add to the BBQL with basic i/o commands?
Surely the C5 is perfect for this weather cut down or not, I take every opportunity to ride my three wheeled device when the sun shines. I seem to remember that when the C5 came out there were rumours of a four-wheeled C10 or C20. Sadly that never happened, and nothing on the Sinclair X-1 either
To make your dalek gnomes a ql-related interactive, put a speech chip in there so they say "execute, execute" instead of "exterminate, exterminate".
I/o port - there used to be a board called the Q-Control 2. It was a project from Colin Opie in early QL World or QL User, can't remember which. It was available years ago from the late Ed Bruley's company, Care Electronics - you might be able to get some info from it from their ads in older QL magazines. Obviously, out ofproduction for many years now, but you may come across it second hand somewhere. I used to have one 20 years ago and built a few basic projects like sound to light units and such like back in those days. I eventually gave it away to someone IIRC, partly because I lost interest, partly I had no time plus I think it was a dead-end device in that it had no through port, so couldn't be used with disc interfaces, memory cards etc at the time unless you were rich enough to own a multi-way expander like a CST Q+4. A little info about Q-Control or Qontrol (not sure of the right name) on the QL Wiki at

Also, consider something like the Di-Ren MPC (Micro Process Controller). It connects to a QL via a serial port (actually, it had a parallel port but most people drove it through a ser-to-par converter), provides some relay outputs which are controlled at the simplest level simply by opening a channel to the serial port and sending byte values to the port.
Various QL magazines have published QL circuitry, indeed one of the earlier issues of Quanta had a circuit diagram from Quanta founder Leon Heller for a simple 8-bit input only port (it worked through the EPROM expansion slot which is read-only unless you resort to drastic programming measures like Miracle Systems did with some of their hardware.
A super gold card has a bi-directional parallel port so it's probably feasible to build some form of I/O devices onto that with suitable software.
I think some general electronic magazines published QL-related projects in the mid 1980s. These will obviously be hard to locate now, but luckily some of these types of projects have been scanned and can be tracked down on the internet, places such as

Nearly forgot about the Minerva Mkii I2C interfaces.
Good luck!
