I am the proud owner of a new Smartphone. I reflect on the fact that in 1979 (or thereabouts) I spent over 1500 GBP on a Cromemco System Z2.
The modified but still working system is still running today
The 90KB Wango drive was over 200 GBP I remember. I think that Cromemco Z80 processor card came from the UK distributor Comart, and maybe even the empty chassis too.
Initially I could only afford 1 floppy diskette drive!
Now it is 2021. I paid less than 200 GBP for an 8 Processor Smartphone with each processor running 500 times faster than baby Cromemco.
Instead of 64KB of memory I am now almost drowning in over 5000 MB of memory, an increase of over 90,000 times. Almost incomprehensible.
Oh and it fits in my pocket, unlike the Cromemco which almost gives me hernia when I move it from the study to the lounge.
The whole Smartphone costs less than the 90KB Wangco floppy drive. Imagine that.
I really never thought I'd see such progress within a lifetime.
