You connect to BBS, IRC, and gopher. 8-bit computers and 64KB ram are still be perfectly usable for day to day use in 2017, they just aren't utilized.

>>821834

Yeah, no. I remember not needing a pause key or pager back then because text scrolled slow enough to read it regardless.

>>821936

The only way to not get snooped is to get rid of your computer. Literally every other way will get your snooped.

I have a 6 MF (megafarad) OTP generator S100 bus card tbh fam.

>>821834

C64 has a delay of like half a second when typing and that makes it unusable these days, i would pick a MSX or a BBC micro

Your CPU is backdoored anyway so even if you use 64kb RSA with true quantum random numbers you're fucked

>>821982

Z80 is old enough to be safe. This was over a decade before the i486 chip, and even early instances of that aren't botnet.

>>821984

Isn't Z80 very slow for RSA crypto though?

>>821999

OTP doesn't use RSA though. Just need to make sure your random source is trully random, and that only the person you're communicating with knows it. Works best for small messages, and when you can physically hand him the key beforehand (or via trusted courier). Also you can't ever re-use any part of the key, no matter what. Ideally you give him more than enough key, on a media that's easy to destroy (like say a CDROM).

Your RSA has no forward secrecy. Can you do a Diffie-Hellman on 9600 baud tho?

I have a Commodore 64 and a Datasette drive but that's it. Maybe there's a nigger-rigged way to somehow wire Ethernet to it

>>822638

The X5000 and modern friends are fairly generic cut+paste boards and almost surely use already compromised ethernet hardware, though I couldn't find what.
