<today at goodwill I found a Advance Micro Device AM2900 Evaluation &
<Learning Kit in the it's box (very nice design on it) with one worksheet
<the unit was only $5.
I must be looking in all the wrong places. That's only my list for SBCs,
next time.

New subject: AE Z-80 for Apple ][e
Hi;
One of the fruits of a dumpster dive this weekend was an Apple ][e
in pristine condition, without a display.
There's an "AE Z-80 plus" card in it. It's made by Applied Engineering
and the date codes are 82-83. Did this card facilitate TRS-80
emulation, or did it just allow one to run things that needed more
power than the 6502?
Of course I have no use or interest in this machine. If you'd
like it I'd gladly send it to you for some small trade. I will
also include the "Dumpling GX" card, the "MICRO-SCI" card (a memory
expansion?) and/or the power supply.

P.S. Is any of this stuff rare?

That would be cool but nothing of the sort. It's simply a Z80 board so
you can run CP/M applications on it. You still need the AE CP/M system
disk to make this work.

No. AE was one of the more popular manufacturers of Apple ][ peripherals
and millions of //e's were made.

New subject: AT&T 6300 PSU Question
I went to power up my AT&T 6300, which hasn't been up for about 4
years, and noticed that the PSU fan was coming on but the drives and
motherboard didn't seem to be getting power. I opened up the system
and was surprised to find the power supply was corroding. Now I'm
not a PSU expert by any means so this was unexpected. The upper
motherboard appears to be ok but I haven't checked the lower
motherboard yet. It appears I can pull the PSU out and replace it
but I'm curious as to why it began corroding in the first place. You
can see pictures of it on my web site on the AT&T 6300 page or at:
http://www.trailingedge.com/~dlw/comp/images/attpwr1.jpg

Any ideas? Also, anyone have a spare PSU? I don't really want to go
buy another AT&T 6300 just for this but suspect the PSU won't be easy
to obtain otherwise.
Thanks for any help.

David,
Wow! Looks like something have exploded inside and left there,
eating away those metals...or a cat had sprayed it or mouse have
known to get inside via a open card slot and pee. And leave rice
sized BM's inside. This kind of corrsion looks like much liquid have
left in there, judging by the patterns of corrsion. Did something
have dripped on that computer? High humidry is out, you have
good metals anywhere else because I had some that was stored inside a
closet with high humidry and came out heavily corroded clone power
supply box.
BTW, what kind of camera and type of lens used you have used to take
this pics? That's very close up work and very sharp.

I thought about that but the system has been sealed fairly well since
I put it in my climate controlled storage space. Still, it does look
like something was spilt on it. No open slots or anything so I don't
know what could have gotten inside.
I have another AT&T PSU I've been using to power the hard drive on my
Amiga 1000. I may find a new power supply for the hard drive and use
that one as a replacement for the corroded one. Still, it would be
nice to know if something was dumped inside or the PSU itself
released something.

I used a Kodak DC210 digital camera I borrowed from work. It's an
$800 camera so I'd hope it would take decent pictures. :-) I'm using
it to redo most of the images on my web site. It's a great camera.
And those images were taken at it's lower resolution.

New subject: CP/M-86 on a IBM PC
I picked up an IBM 5150 a while back so I went to the
Unofficial CP/M Web Site and downloaded the distribution images of
CP/M-86 for the PC. Then I hit my first hurtle, I had to create the
disks on a 360K drive. The only ones I had were on PC's without
harddisk except for my AT&T 6300, which is dead but that's another
message. So I pulled the floppy drives from the AT&T and plugged
them into my 486. Of course Windows 95 didn't like the program which
created the disks so I had to find a DOS boot disk and but finally I
was able to create the floppies. Finally I'm booting CP/M-86 on the
PC and loving every bit of it. You can see the operation on the IBM
PC page at my web site. Another old machine lives!
