Consulting?

I am very grateful to this audience, because when I used Sinclair myself, I was in 7
heaven, but times change, and now I’m sitting on 4, waiting in the cold, as they say, but in general the question is this?
How much technology has advanced, but namely:
We installed a screw
Is it possible to hook onto the IBM port or what other connection have we come up with?
For example, if I downloaded mail on 4, dumped it on the sinclair, and so on in the car
when I had time, I read mail, and if there was an opportunity, let’s say I wrote
replies, and when I came home all this reset to 4k, and at a speed of 14400
would give it to the boss.
Maybe someone can enlighten the lost brother?
I would be very grateful!

Good Luck!

Alexander.
