<p>Michael,</p>
<p> That's rather dis-heartening if boards are no longer
available for a 10 year old product. Got a long day out of town
today but will ruminate on responses.</p>

<div dir="ltr">I just pulled out an 8048 and replaced it with a
8048A due to the lack of AC boards for 8048s. I didn't know any
better and put in a new 8048A board and learned the hard way
that they aren't cross compatible. Smoked it. If you think you
can find a board for it, it's yours.</div>
