I got in touch with the makers of the piece that I was attempting to put into Jess’s PS2 about the part I inadvertently removed, and they told me exactly which bit I should buy. So last night I proceeded to buy 5000 of the things (they sell them in reels) and got them today. Popped the tiny little part in and…
…it works!
So that’s me a happy bunny realising I haven’t broken the PlayStation, and Jess happy I haven’t broken her toy. Phew. Ah well, it looks as though in the end everything comes together: the SATA controller, the 2 new PCs, and now the final thing: the PS2.
