I did run a hackintosh on one very long ago.  IIRC it was a core I 2 not 
very bright bulb.


That's not on topic either, but worth knowing.
thanks

I can also vouch for "Biff".  I've transacted with him before (traded an
IMSAI 8080 for an Alpha Syntauri system he had listed on eBay...I proposed
the trade and he was kind enough to go with it, so I know he will work with
you).  FWIW we are also "Facebook Friends" and he's known in the computer
collecting circles there.  A very great guy.  He runs an e-waste processing
facility in the midwest.

[cctalk] Problem with Dell Vostro 1700

2024-04-05 Thread Van Snyder via cctalk
I have a Dell Vostro.

When I boot, the screen briefly flashes and then remains dark.

I have another one on which the screen would stay lit for a minute or
two, then go black. If I closed the lid and opened it, it would stay
lit for a few more minutes, then go black again. I corrected that by
replacing the backlight power supply.

In this one, is the problem more likely a defective power supply for
the backlight, or a defective backlight, or something else?


Thanks,
Van Snyder

Kevin,

Thanks. but isn't there a big risk with that item that it doesn't 
work at all, given the "for parts" designation? I suppose I can email 
and ask if it POSTS...

You can still run a 32b OS or 32b applications depending on your

prior ISA versions.  I re-read your post and it seems you want chipset
compatibility though, in which case yes you'd want to find a LASI
system like the C160L/C180L if going to C-class.  Here is a good

I don't understand the silly pricing either. Who's buying them? Who is
forking over $1000, $1500, etc for these old machines? I don't really
even buy the "some business relies on this and have never updated"
because you'd have to have some smart folks on standby who could
reinstall software, reconfigure machines with licenses, etc. Assuming
you still had the necessary CDs etc.


I think there is a small subset of PA-RISC machines that are used as
controllers for ABB PLCs, maybe other types of industrial and lab
equipment.  It might not be a big deal to spend $1200 to maintain
something like that and not have to understand how to make it run on
other types of systems.  The sellers then extrapolate that to
everything is worth its weight in gold.

I can vouch for them as a seller in the same way, I've also gotten reasonable prices from 
them when making offers that account for shipping, and the seller actually knows how to 
pack stuff. Same with eBay seller jonnyadler, though their list price for a C180 is,

DEC made the KV8/I option (
http://www.bitsavers.org/pdf/dec/pdp8/pdp8i/DEC-8I-H6MA-D_KV_Graphic_Display_System_Maint_Apr70.pdf)
for the PDP-8/I and PDP-8/L. It had a analog function generator which could
draw vectors and circles. The board is A312 and is a Dual module. My board
look like this:
https://svn.so-much-stuff.com/svn/trunk/Eagle/projects/DEC/Axxx/A312/A312Efront.jpg

THE KV8 was made for connecting to storage displays like the Tek 611 / VT01
and not displays that need continuous updates.
