On impulse, this NOS MAG monitor showed up on eBay, and I pulled the trigger. It's a low-end 15" MAG with a non-flat screen, but it came in the original box and foam, so I knew it would survive the journey to my house.
I'd decided to give up on CRTs except for my Sony PVM, but I couldn't pass up a brand new model.
I wanted to to add for my recently purchased SB CT3670 ram modules.
Well description was clear - single sided 30-pin SIMM. Note next to picture was little bit concerning - "Example Picture - Image similar", but seller was well known german shop elecromyne. What could possibly go wrong...
...and I received this:
So other side has pcb-like material covered with painted black metal plate. yikes!!
They just fit, but they are clearly under tension.
Then again - black matte color, very modern, only RGB is missing...
...also Made in Germany!!

I have a few of those as well, I think is was an extremely low-budget brand called "Topless". Sometimes they are like these plates and sometimes more like blobs of black plastic.
I did a Google image search on "topless" for some examples but then I got distracted...
Something definitely "rammed" it .
Seriously, if you can't easily replace it, maybe you can disable the affected RAM bank .
I need practice with smd anyway so it's going to be a good opportunity. Good thing it's a generic S3 card and not something valuable.
Can these 514260 memories be replaced with 53C16258 from a different S3? They are pin/package compatible but timings are different.

I don't pretend to be an expert at SMD soldering because I'm not, but I'll tell you how I did when I desoldered the memory for my S3 a few pages back. I turned up the iron some degrees hotter than normal. The display on the Yihua (you can tell the quality from the brand alone) said 350°, but it's out of calibration so I'd say about 320-330 actual degrees. I then put a big blob of solder that covered all the pins on one side of the chip, and then kept moving the iron back and forth to keep the entire blob molten while pushing this side of the chip up with a small screwdriver. No need to use force, once it's molten it'll tilt up very easily. Then remove the leftover solder with whatever method you prefer.
Finally repeat with a blob on the other side, except since one side is already free once the tin it's molten the chip will be free without having to pry it.
Disclaimer: this is not the proper way to do it, professionals™ or anyone who sort of know what they're doing would use hot air, but without it you kinda have to be creative.

Some stuff I've picked up the last period of time. ASUS P/I-P55TP4XE. Socket 7 430FX w/ 512kb L2 PB COAST module & optional PS/2 bracket connector (not in picture) (1995). This was ASUS's highend board in 1995 and into 1996. Released in autumn 1995. Supports all up to the 200mhz Pentium (233 by 1.5x). The P55TP4 versions were:
-P55TP4 - Only async cache, no COAST module socket
-P55TP4XE - Sold with either 256/512 Async cache or 256/512kb COAST module (I got hold the best cache option). IR connector
-P55TP4XEG - Same as XE, just without IR
-P55TP4N - Released a bit later. 256kb PB cache hardwired to the board with COAST module for another 256kb.
Unfortunately the board was damaged in shipping and the DIN connector came loose, as the board only came in a thin padded envelope! I need to solder on a new one. Still powers on fine.
I thought I'd backup the BIOS for a P55TP4XEG I acquired recently and upload it here before upgrading as I don't see it available anywhere else. BIOS version is 1.15.
Most interesting things for me:
- Asus TX97 motherboard (Socket 7, i430TX, K6-2 ready) - need to replace the caps
- Sound Blaster Pro 2 CT1600
- AMD 486 DX4-100
