Thank you for taking the time to comment! Yours is a very nice collection! This PS/2 means a lot to me because it was my first experience with PCs when I was at school. I believe the 8086 can only have 640KB of Ram, if yours had 1MB, it might have been the 286 variant - it's still called "model 30".
Good luck with the 486 motherboards! I have some socket 7 to fix!
Thank you very much, I put your YouTube channel under observation, from today I plan to follow it, both because it is of interest to me, and also because I like old PCs a lot, on the contrary I like the new ones relatively less, but I have some to fairly recent fixes, if you have seen something in my link, you will have noticed that I don't have a particular preference, generally I like everything before the PII, speaking of S7, I have several under repair, unfortunately I have little free time, and equipment limited, add that I am not a professional repairer, but apart from the most complex cases, I have a certain success rate (which can certainly be improved).
About IBM, I'm not sure if it had 1MB, maybe you're right, but I'm sure it wasn't a 286, because it had 8 bit ISA slots, I also started with an XT (assembled), it had a frequency of 12 -15MHz and this is 1MB of RAM, there was DOS 3.3 and Windows 1.03, I still have these programs today on an 8MB CF, ready to use on PCs like this, in case I find one to put in a collection.
