Probably unrelated but someone appears to have impaled a smurf with one of the resonator legs…

A very curious looking zeddy with an exceptionally well preserved box!

Seems to be working nicely apart from the keyboard:

It's a toast rack.
Reminds me, next week Saturday there is toast Hawaii on our annually meeting :mrgreen:

I fitted a VLA81 to the dodgy issue three and got a K but a very flickery screen.

I replaced the voltage regulator and now I have a rock solid K. The screen is actually white. Not really sure why the camera thinks it is so blue!

Change the colour balance settings on the camera. You should use different settings depending on the source of the light.

Or use a image editing application to adjust the colour balance of the existing photo.

Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb :!:
Looking forward to summer being good this year.

Never even crossed my mind to do so!

Somewhat better. 8-)

A caseless but booting to a K zeddy! Truly these things are resilient. 8-)

Also a pretty nice issue one manual and Vector Maths tape.

The tape, I have to admit, is not my sphere of interest!

A shame really as the zeddy when used as intended by Clive is quite good where complex maths is concerned be it matrix inversion, complex formulae etc, especially with Forth, and contrary to popular belief it doesn't take half a day to do it. :lol:

I never really got on with maths! Too many other distractions in life to try to get to grips with it now. :shock:

If it is of interest pm me your address and I will send it over.
