I'll write no. The display is usually different from model to model and rarely interchangable.
Instead, I find it best to optimize what I have. Simple things like uninstalling any software I haven't used in a few months, changing the antivirus to something less filling (Free AVG from www.grisoft.com) and such usually kick up the machine enough.
I have an old Tecra 8000 with a PII 366MHz processor. I would like to know if it is possible to get a new mainboard and processor or am I just stuck with what I have? If it is possible, where would be a good place to look for prices and such? Thanks in advance for any help anyone can give.
