This yes that was a good purchase! An IBM 5155 laptop. Spectacular!
This time I went to collect it personally, to avoid transport problems.
Here is a short video I made, related to the test of this magnificent IBM5155 retro computer.
The keys on the keyboard really sound fantastic.
Is it the computer that John Titor used to travel through time? No! That was an IBM 5100.
