Anything that will store bits for an IMSAI with the stock 8080 processor
card.
Thanks

I need a S-100 RAM card of any size to test my
IMSAI. If
anyone has one
they feel comfortable parting with, please let me know.
Your last msg did make it. Do you need 8 bit, 16 bit,
static, dynamic,
16 bit address, 24 bit address, mixed RAM and ROM, do you have a boot
ROM of some kind, what CPU card are you using, do you have a front
panel? I'll check and see if I have anything to spare this weekend.
The catch is the S-100 boxes are piled 6 hi and chances are the spare
card is in the bottom one, plus I have to unscrew each top to look
inside.

All right, darnit I'm back. I moved jobs, started my new business and
found out the new business only requires about 20 hours of my time every
month and a half. :-/ And I've still got a garage and basement full of
iron beasties waiting for resurrection.
So...
(BTW, Allison and Don Maslin, I think I owe each of you $5 for some docs
and disks you sent me.)
I opened up my Lisa with the bad video (weird horizontal sync problem)
and discovered that the batteries in the back have corroded and dripped
down the I/O board. Some of the contacts that go into the motherboard
have corroded and, without seeing a schematic, I'm wondering if this is
causing the sync problem. I verified that it's the video driver
circuitry and not some malfunction of the monitor by connected a
monochrome monitor to the Video Out jack on the back and seeing the exact
same behavior.
At any rate, I removed the offending batteries and will clean up the
board. Are the batteries necessary? If so, what for? If so, what is a
viable replacement for them?
Is my theory about the video plausible?
I've got images of bootdisks etc floating around in an email box
somewhere on the backup tape from which I had to resurrect other email
messages so once I get the video cleaned up I'm ready to rock and roll I
think.
Also, I have a Profile harddisk that alledgedly goes with the unit.
Without documentation, I see no place that indicates a hard disk should
be connected there on the Lisa. But the Lisa has one parallel port and
an expansion board with two more parallel ports. Does it connect to one
of these? If so, what cable is appropriate? (No cable) And to what
should it be connected?
Thanks in advance for advice and assistance...

Oh, bleep. Let me guess you've got a Lisa 2/5. They're infamous for this
problem. I was able to get to mine just prior to the batteries really
messing stuff up. This is most likely the cause of your problems, any
chance of reparing the damage?

No, you can boot without them. IIRC it's a _slight_ annoyance not having
them, but it does work. Besides the clock won't go past 1995 so who cares
if that is wrong :^)

I hope someone remembers this, it's goes in one of the parallel ports on
the expansion card, it will ask you which one when you boot. The problem
is, there is some sort of trick about the cable IIRC, the thing is, I don't
remember what it is :^(

And if so, does anyone know what's special about the cable? That might be
the source of my Profile problems with my III.

Is the image on the screen wrapping off of the edges, or is it all within
a well-defined rectangle at the center of the screen? If it is the
former, then it does sound like a horizontal sync problem; however, if it
is the latter, then your Lisa has probably been fitted with the "screen
kit upgrade", which changes the screen resolution from the Lisa's standard
720 x 364 to 608 x 431 to better approximate the Macintosh pixel shape and
aspect ratio. The Office System doesn't recognize the "upgrade" and still
writes to video memory assuming that it is in the original format,
yielding a garbled screen.
If you can find a copy of MacWorks, try it out. If MacWorks runs, then
you will need to downgrade the upgrade (with original system ROMs, the
video state "ROM", and the removal of the transformer included in the
screen kit upgrade from the video circuit) to make this system run the
Office System.

The corroded nicad pack you mentioned earlier is a "feature" of the 2/5.
On a 2/5, you should be able to plug a ProFile into the built-in parallel
port, without using an expansion slot/card at all. A straight-through
wired DB-25M - DB-25M cable (with pin 7 cut off on one end) should do the
trick.

I managed to pick up at a thrift today the Lisa 2 Owner's Guide and a
MacWrite/MacPaint boxed set. This last item is notable because in it,
along with all the retail pack MacWrite and MacPaint stuff I found a
shrinkwrapped MacWorks disk package and a receipt from Sun Remarketing for
a Mac XL ($995 + $3 shipping). Maybe the Lisa will show up tomorrow
morning, I must remember to stop by on my way to work. (:
Anyway: the picture in the back of the book shows the Lisa 2/5 with its
Profile disk stacked on top of the CPU and.. a DB25 ribbon. So it's
definitely straight-through. It is depicted connected to the internal
parallel port which the Lisa 2/10 lacks. (The manual states the 10 MB
widget drive plugs into an 'internal parallel port'.)
