Unfortunately DonutKing I'm not ready to pull the Osborne down yet. Some more photos are coming though. As I said early on, I will try tackle the easier projects at the start. By that time I should gain some experience to tackle the older machine. Have a massive tidy of Man cave to do + Workshop area. Preparing space for the projects & clearing some horizontal bench space. Want to start looking into Time capsule on Monday. Thankyou for the answers. So Osborne has Heatsink. That could mean 5v board ( + upgrade cpu that was optioned then ?? ) You say Intels were the desired ones then, compared to others. Watch out re: Psu noted. Thanks Being like a 20year old machine, that means was around when Win95 OS was kicking. That a sucky OS ?? OR a possibility for these machines? What are expansion cards that have some quality in these machines? Can try get a better pic of them. I can't see any battery or Dallas clock chip. This I must find first?? Speaker has continuous squeal.
