hi to everyone,
from time to time I need a frequency standard for calibration etc. I found many circuit diagrams on the Internet. All are 10 MHz, but some I doubt the precision. I would like to know what is the best method to get a 10MHz signal for calibration test instruments.

I found another problem with my HP-85. The cassette won't rewind, but the tape drive motor is whining, don't know what to do about it?

I have an HP-85 computer and some keys do not come back when pressed. But the keys work. When I press the A key for example, the key stays down and the letters A's quickly jump on the screen until I lever the key back up. Does anyone know how to fix this problem?

there is a software simulator in Basic for the Diablo16 processor (displays 4D). You can immediately see what is happening on the display.

so what is coming back to you?
