Re: Apple IIe and Profile (Power supply burned out?)

[cjyo@my-deja.com]

...Well, I walked in to my office this morning to find that one of my
co-workers had bought me a complete Apple II+ system for $7 at a Church
sale.  I guess I was talking a lot about the IIe last week...

Anyway, the first thing I did was switch the II+ on to see if it
worked.  It did, but there are thin vertical lines all across the
screen.  I guess the video chip has gone bad.

The next thing I did was try the II+ power supply in the IIe.  Still
nothing (with no cards in) - just the same thick vertical bars on the
screen.  I took another look at the IIe power supply and I think it is
actually okay - the fuse still looks good.  I'm sure glad I didn't
order another power supply.

I think one of the chips on the IIe motherboard must be burned out.  I
popped out a few of the chips: CPU, Video Rom, etc, then put them back
in, but that didn't change anything.

I'm going to give up on that IIe, since I have the II+ now.  The II+
has a 16mb RAM card (so a total of 64k, I guess).  I also put in the
IIe's CMS SCSI card, SD-20 hard disk and also the Profile hard disk and
controller card.

On the II+ the CMS drive does boot like in the IIe, with a ProDOS 8
v1.4 screen.  I didn't get a chance to try the Profile drive on the IIe
before it died, but on the II+ the Profile disk says "unable to load
ProDOS."  I guess the Profile may have a newer system and the II+
doesn't have enough RAM.  I realized today that the CMS disk doesn't
have a terminator - I wonder if that could have fried chips on the IIe
motherboard (even the the drive and SCSI card still work)?

What started out as a free project (I found the full IIe system with
the CMS and Profile hard disks), is now getting "expensive."  Since I
have already ordered some manuals, system disks and a serial card, I
will probably try to buy another IIe system that can handle the hard
disks...(and has a good video chip, unlike the II+)

Or maybe I'll just buy a GS...I've never played around with those
before.  But it's not as nostalgic...

Maybe I should have never picked up the IIe in the first place...?
