Radio Shack TRS-80 Model III vs. Dell XPS 9000
-VS-
My first personal computer was a Tandy Radio Shack TRS-80 Model III. I got it when I was very very “young”. Just ordered my new Dell XPS 9000. I think it would be interesting to see how technology has evolved from my first to my most recent personal computer. Hope my math is right.
Component : TRS-80 Model III : XPS 9000 : Delta
RAM: 16 KB : 12 GB : +75,000,000%
CPU clock speed: 2.03 MHz : 2.66 GHz : +131,034%
Monitor Size: 12 in : 24 in : +200%
Storage: 356 KB Floppy Drive : 2 TB Hard Disk : +280,898,876%
Cost: $999: $2,500 : +250% (Inflation ignored)
There were also other interesting facts about personal computing at that time using the TRS-80 as an example. The monitor was Black and White. There were no bit-mapped graphic although we were quite creative with character-based graphic. Screen resolution was 64 x 16 characters. The floppy disk was 5.25 inches in size. Hard disk was not available until a later time. Mass storage was external cassette tape. There was no such thing as pointing device (i.e. mouse). Windows 1.0 has not been invented until a few years later. There were two interface ports: RS-232 serial port (i.e. for modem) and a parallel port (i.e. for printer). Modem speed was 300 bit per second. In addition to program in BASIC, the other logical option is the Assembly language with Peek and Poke.
Life was certainly a bit simpler then.
