Found it Rich, 15 months after Sidewinder but only a couple of adverts in July 1982 for the machine but not on it's own...

When this was first released the nudge tune was all garbled, there was a very obscure bug in the cpu emulation that caused it. Luckily it's all fixed now 🙂

You would think so Rich but I can't find any press info on the super version around the time of the original Sidewinder.

that monitor is spot on! super!! tidy machine!

Here's one that had me going for a bit and that was on test in my Cabaret machine. There is a double lamp on the £100 win and when in test mode it wouldn't light. It would however in attract mode??? This was accompanied by a 0700 in the LED display. After a little head scratching and reading the game manual I realised it was telling me it had sensed a short circuit lamp and was showing #70. Looking on the manual showed #70 to be the £100 lamps! Both lamps were OK and with either removed passed the test OK. Let's have a look at the diagram to see what might cause that. MPU3 circuit diag cropped.pdf The lamps in question were connected to Blue (6) which is driven by T35. The resistor on it's emitter R41 (2R2 Ohm) will show a voltage across it, it's value depending on how much current is drawn. In this case the resistor wasn't 2R2 any more is had risen to about 3R4 which was enough to trigger the sensing circuit (T38), turn the lamps off and show the position in the LED display. (clever chaps these software Johnnies)
