Double your IBM PS/2 Model 55 SX's memory with this one weird trick!

The right kind of memory is hard to come by for vintage machines, especially for the IBM PS/2s, which use special memory SIMMs and like to have a chat with their memory modules before they even start booting up.
But it turns out that you have a chance to step into that process, and force SIMM modules to self-identify as slower memory, to please the host. Thanks Peter Wendt: www.mcamafia.de...
And that's what I did.
The weird trick is one tiny ball of solder.

That's one happy capitalist tool.

What did I just watch... 😅 1) come mai me conta 8064 di kB? Dove finiscono gli altri 128? 2) lava quei rimasugli di flussante dalla saldatura con un po' di isopropilico 👍

1) I PS/2 riservano 128kb per il cosiddetto "high performance BIOS" 2) ok, but tests come first

@@scarpaz so how has the memory performed while in use? errors?
