The day before yesterday, I unexpectedly discovered that my old (but in excellent condition) HP monoblock (OK - all-in-one PC) supports 4 gigabytes of RAM. HP Compaq Presario 100eu AIO. I was sure it was 2, because it was said on the official website and on a bunch of other sites at the time of purchase (quite a long time ago)
The PupSysInfo program gave me the info. So thanks to @radky.
Yesterday I (again unexpectedly ) discovered that there are just 2 slats of 2 GB each of DDR2 SODIMM memory (Patriot company) still lying in stock at the local store. The last "survivors" in the store That's a coincidence, I thought, and decided to add memory.
I'm still thinking about whether to replace the built-in DVD drive with a second hard drive or let the DVD live
Therefore, if no one kills me and there is time, then I will definitely assemble a new Puppy. I haven't decided yet based on Arch or Ubuntu.
These things will live for a while :
