Happy AIM-65

All the HP flat-bed plotters use that same electrostatic paper hold-down.

Thanks for the info about these.
I did think my (a bit blurred) photo had HP86B on it, but when I looked at the CfCH event listing for what you had, it says HP85 so I guess there was a typo there.

I attended the Computing Museum Retro Computing Festival, it was great to catch up with you Jeremy.

It was great to see the AIM -65 up and running!

I snapped a quick picture of the AIM-65 while chatting to Jeremy, here is a link to the picture I took.

The AIM-65 is now happily installed in the custom case that came with it. Apart from anything else it protects it better. I have used a small cool-running switch mode supply (Meanwell RD-35B) instead of the huge original linear supply, which I will keep for posterity. The original supply runs very hot so needs lots of holes on the box, and may heat-stress an enclosed AIM. I have added an external reset switch (essential) that can be unplugged if the AIM is run lidless. It looks so smart that no-one will think it’s original now!
