Questions about Flynn's Machine/Server

We know it's a machine/server from the 80's 1982? or 89

So i ask what is the ram you think? was it mentioned anywhere on the movie? i forgot when sam is at the terminal etc

So the ram would be what? 4mb or 64mb in a high end machine during that era?

We know the type of cpu it was i1386 but registered as unknown.unknown on the movie lol

No doubt it was running an early form of an SSD (seeing as commercial enterprises used them in the 80's and 90's before the public got them) No way can a HDD run 24/7 for 20 years ?

And the uptime was over 20 years, so who's been footing that bill?

How did the "pager" signal get out to Alan? if there is no connection linked anywhere? that machine wasn't linked up to the net but the number was disconnected for 20 years and then reconnected?

Still it's plausible a machine can be left running for 20 years though.
