Well, we were given a REAL gem. A genuine IBM computer, a FOUR megahertz 8080 WITH co-processor. A real screamer! Funny, I remember, it belonged to a friend, a college prof, and he got something better (how could you get better than THAT
I remember he still had a spreadsheet with grades on it.
I scrolled down and like we see to day, scroll down and it goes down quickly.
Not so on THAT box. It fiddly farted around and the first couple lines of the SS moved a bit and then a blank line appeared and then the next line above jumped into the blank space. THAT was scroll. If you wanted to get down to the bottom of a long SS list, be prepared to wait about a half hour
Now we have what, ten thousand times the power in just our cell phones? Times have changed, eh.
My first comp was a TI-99 with I think 16K of ram. So I started a project of hand wiring a 64 K memory board, got the proper connectors, chips, wire and such and started hand wiring the thing together.
I got about half finished when I saw an ad come out in some electronics rag. Now available, the one MEGABIT memory chip. Ah shyte! I threw my half finished board across the room in disgust. My board was obsolete before it was even finished
One megabit chip= 128 Kilobytes of memory! Quite something for back in the day!
16 bit chips couldn't even address that much, limited to 64 K unless you did some tricks.
24 bit chips could only do about a megabyte or so.
32 bit chips can only access 4 gigabytes and now we see 16+ gig ram so we have to go to 64 bit chips and they can access about 18 TRILLION bytes so I don't think we will need much more than that!
