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 Jim On 4/5/24 19:41, Bill Degnan via cctalk wrote: I find them to be painfully slow Actually I think it got a lot better once I installed debian in it.

That's not quite on topic here but I used to own one. Just close the lid and walk away slowly.

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. Sellam
[cctalk] Problem with Dell Vostro 1700
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...

Thanks guys for pointing out what's available and the references which will be useful the next time something good comes around! The C200 runs the newer 64-bit processor, the PA8200, which is RISC 2.0, and (I'd imagine is) quite a bit different than the PA7300. I don't understand the silly pricing either. Who's buying them?
