There really is no need to convert it to a B unit, as the A unit has the same specifications. If you put John Seamons' BBB CPU card in it, it will simply sing as far as speed goes, and you can use the A or B virtual roms as you wish.
The principle difference is the B analog boards are easier to calibrate, and, have a different range of threshold settings on the front panel knobs.. -Chuck Harris Perry Sandeen via time-nuts wrote:
List, I won a 5370A from ebay. Though it seems to be missing the A channel level knob, the unit was shown powered up with the correct 0.0 on the display, although the unit was sold as non-working for parts or repair. But the price was right with a best offer accepted. So assuming (gulp) that the unit works after fixing the A channel problem. is it practical or desirable to convert this to a B unit? I have one of the new processor boards with the BBone option that I can use in the unit. Advice requested.
