wow, you are right! I didn’t bother to check this whole time of needless suffering, but for what I earn with it in less than an hour I could probably buy 2x8 GB DDR-3, lol!

It just seemed a fair assumption that it would be insanely expensive …

I bought a desktop PC for a little over 2k in late 2011, and still use it. I’m a back-end developer, and certainly I would like to be able to upgrade my 16 GB RAM to 32 GB in an affordable way.

Other than that, it’s perfectly fine. IDE, a few docker containers, works.

And modern gaming is a scam anyway. Realistic graphics do not increase fun, they just eat electricity and our money. Retro gaming or not at all.

Imagine how things were if they were built to be maintained for 15+ years.

Thanks! The whole PC had a time (when its age was ~20 years) where it still booted, but with reset BIOS settings, followed by a time where it doesn’t boot up anymore. So I believe the most likely thing is that it leaked and caused damage. Retro computing community thinks that the most likely cause is battery damage.

Here is the exact model from someone else: https://theretroweb.com/motherboards/s/msi-3121-v3

Battery (top-left) already removed, but it shows that this one has leaked before as well. When you look closely, you see battery residue on the nearby 8-bit ISA (?), so it must have leaked a lot at some point and been cleaned up. Unfortunately, it came with a notorious Ni-Cd Battery; even for its time not the best.

I have an old mainboard from 1990 with emotional value and a leaked BIOS battery. And advice for cleaning that?

In order to change the degree so that it allows studying in many universities abroad (such as Germany), this would be needed:

• functions and graphs, mostly R->R
  • general analysis, continuity, function as a specific type of relation
  • series, sums, limits
  • derivatives
  • integration
    • numerical
    • basic approaches and when to use which
    • a few common “tricks”
• proofs: very basic direct, induction, contradiction will do
• set theory
• Vectors, limited to R³, line, plane, rotation. Very basic matrices
• introduction to imaginary numbers
• stochastics & probability

It’s based on my subjective impression of weaknesses in the few Americans studying in Germany that I know.
