scanning random chips

[xrror]

Another machine passing through the workbench. Still aiming to get the K6's next.

[xrror]

Hrrrmmm, the scanjet seems rather unhappy at me for some reason. Trippy K6-2 wallpaper anyone?

edit: Random amusing thought, imagine if this happened on a computer used exclusively for OCR text scanning.

[xrror]

Finally starting to get these scanned in. If I can find them all there should be 8 K6's to scan naked

Hopefully I can figure out what's up with the scanner though!

This chip is probably going to get rescanned since it's both really dirty (ewww) and the scanner totally fubared when scanning the bottom. Also this chip is rather interesting since it's a "de-binned" K6-III. The letter written on the ceramic top are where I was looking up what resistors (are they?) to try and resolder/move to re-enable the full cache. Problem is I don't have any way to solder on the ceramic w/o destroying/overheating the chip!

EDIT: going to get rescanned. The pin/back pic is just the garbled one hastily re-aligned with mspaint and it shows. Ick.

[xrror]

scanned mostly to see if the scanner is working any better. Unfortunately you can tell it isn't

EDIT: ugh this is getting rescanned. If the screwed scan wasn't enough, the nasty hair/whatever that stuff on there is nasty.

I'm playing around with parallel port settings under winXP. Hopefully just that or the cable is too long. Also I'm thinking with the de-lidded K6's I might break them into 4 scans, since on the 333 above you can't read the heatspreader at all - which makes it kinda pointless.

Any thoughts on how to get the lettering to show up better?

I'm not sure if i want to de-lid the K6-III I have - okay on 2nd thought it's getting de-lidded since well, that's the whole point right . Though I can't remember if I already did that. Hopefully I can get that machine tomorrow (Monday) if my buddy (who had a truck to haul stuff) is available.

The K6-2+ and III+ should be fun ones to see. Need to pull them.

Maybe you can try rubbing some colored chalk over the heatspreader, which should fill in the etching and make it easier to read. Just make sure you wipe off the excess so you don't get lots of chalk dust on your scanner.

The same could be done with a marker or wax crayon, but those are harder to clean off.

[xrror]

Thanks for the idea Neon. Yea I was pondering using some of those paste waxes that tend to leave a white film, but then cleanup is a pain. Plus it might obscure the "metal grain" too. I just noticed now the 4 "dents" on the sides of the K6 heat spreaders are always at a certain orientation to the metal grain, which probably is just showing how the metal stamper was working.

More fascinating is how AMD didn't really care what orientation the heat spreader went into the stamper. Then again that's probably only fascinating to me

I did find the K6-III+, so hopefully I can get the scanner issues fixed. I switched machines, so maybe just a quirk with the current "scan station"

I'd be interested in seeing naked K6's so I can compare their die sizes




...now that doesn't sound right...

[xrror]

arrrrrrggghhhh... I swear, I'll get the K6's scanned if it's the last thing I do.

Of course at this rate, I'll scan a naked K6 and K9 prototype together and the glass will break

I'm to the point of just moving the scanner to another computer to see if it "just works." Been too busy with random stuff - never seem to get enough free time to sit down and mess with it.

But the de-lidding is mostly done. I'll try and get a low dpi preview scan (the scanner pukes more at higher dpi).

i'm really looking forward to seeing the K6-2+ , III+ and the III for comparing - I haven't gotten those dug out yet.

[xrror]

I haven't forgotten. I swear

Real Life (tm) fun crimping my scanning style. In good news (maybe?) friend brought over the remains of an Odyssey 2 which has a socketed(!) Intel 8048. So I can scan that just to be silly

The scanner problems remain unresolved, so I'm just going to move it to another machine. Which should be easy... but requires me to do some actual procrastinated cleaning.

I use dry erase markers to fill in on K6-2s, just cover the lode, and use a dry rag to wipe off the excess, this is the result:

[xrror]

Wow, that dry erase comes out nice. I'll have to pick some up for this.

By scanner problems I was more meaning the corrupted scanning. Hopefully later tonight when I'm off work I can get around to moving the scanner. I've started a new "job" and it has really been kicking my butt. When I get home at 6am all I want to do is sleep

[CPUShack]

at 6am all I want to do is sleep too LOL
