I found the schematic and compared it with the 10811A.
I guess I'll just plug it in and look for smoke signals !!

Is the 10544A interchangeable with the 10811A ?
If I plug the 10544A into the controller board which
previously held a 10811A will I fry anything ?
Anyone have a manual for the 10544A ?
Thanks,

I believe you can find the 10544A info on the HP Archive website.

What piece of equipment are you trying to plug it into? I'm sure

One difference between the 10544A and a 10811A is that the 10544A requires +12v
on pin 8 in order for the heater to turn on. Without this signal, the heater
will appear to be dead, even with the proper voltages on the heater pins. So,
you may have difficulty using a 10544A as a direct
