Even if you use the nominal value of $1600 as opposed to the "real" value, you're getting way more capabilities.
I bought my 2003 VW Golf brand new from the dealer for CA$ 30K all-in, and after inflation that's the equivalent of about CA$ 40K nowadays. I'd get a pretty good car with much better tech and safety even for $30K, and could get something relatively fancy for $40K.
That $1600 Tandy would equate to ~$3250 in Today's day and age.
So, essentially an M1 Pro/Max MacBook Pro.
