The options weren't great back then, unfortunately. The .PNG spec was brand new and hadn't caught on yet. Unisys was shaking everyone down for royalties on the .GIF patent. I'm not sure .BMP existed

I have looked extensively, but have not found a 24V fan with the necessary airflow specs that also had quieter operation than the fan already in the unit. You mention that you have done some mods to

Awesome, thanks! My battery is completely dead, even running it for a few hours won't charge it. Hope you share the modification if you ever get around to it. :o) Sean

Yup, that's the one, not as nicely made as the HP original but it dropped straight in and is still running! I'm not using the 8566A as much as I was these days so I find I need to fire it up for a few

Steve, Is that one fit a 8590A by chance? I have another box that has a noisy Yig in it as well. I suspect the yig heater isn’t working, it drifts +- several hundred Khz. Causing to analyzer to fail

NiCd cells are 1.2 V nominally, making the 3-cell pack 3.6 V, a bit higher while fully charged. This is the correct value for the HP 8566/68 A, I wouldn't confidently put in something like 4.5 V or
