Yup. Saw an ad in the latest Info magazine by Phoenix Electronics for
an replacement A500 power supply ($100 I THINK). Sorry, didn't have the
magazine with me. If anyone is interested, I can post it here. I'm not
affliated in any way with Phoenix Electronics.

Or you could purchase a cheap switching power supply ($40 to $70) with
about seven amps of 5VDC (much more than the measly 4.5 amps 5VDC
provided by CBM's version). But you would have to come up with a
connector to plug into the power jack on the A500.  Just check any
Computer Shopper out for the power supply bargains.

On another issue, I was not really satisfied with the 1 meg of memory
available on my A500 ... I am *seriously* contemplating doing something
(akin to Chris Erwin's hack) to add 512k or 1 meg to my Amy. But with a
new twist - auto configuration, if it is feasible. I'm still doing my
feasiblity study. Anyone care to comment ? 

I can go over several issues in the area of memory upgrade hacking,
but I need to know if anyone is interested ...

	Boy, do I love hardware hacking !
