It triggers me more that the (E)EPROM is not in a socket 
Because the pins aren't completely engulfed in solder at the top/in the holes? The through-holes are totally full of shiny metal from top to bottom.

These will destroy any socket you put them into. Or won't even fit in case of turned-pins sockets.
Pretty sure those things didn't exist back in the day - we used long-pin turned sockets (designed for thick multi-layer PCBs, I believe). Got the scaling wrong on Mk I and the pin pitch was just fractionally under 0.1", requiring a bit of ... um ... "technique", to get them assembled!

He he, I guess it'd be useful for lazy people like me not to have to set it each time I start the computer.Ruptor wrote:Why is an RTC useful on a stand alone computer?
