<tr><td colspan="2">Batch spice processor for RISC OS. BSpice simulates non-linear dc, linear ac and transient signals in electronic circuits, making it the best tool for advanced student or professional circuit designers.<br></td></tr>
<tr><td colspan="2">This is an ancient single tasking program to prepare small electronic and/or logic diagrams. Written for an operating system called Arthur, I think but it will still run on all Acorn machines. There also is a user guide.<br></td></tr>
<tr><td colspan="2">This is a rather nice Stepper motor controller. You can change speed and direction, single step or turn a pre-determined number of full turns.
Output is to either the printer port or the user port. There is no help file at the moment, but the controls are fairly obvious. I have included a PCB negative. I can send the board at near cost, but you have to supply your own stepper motor.<br></td></tr>
