Yes it was exist my friend. May be officially it started 2011 but in that dates i was so away from online connections
Exactly end of 2008 or first quarter of 2009
I tried all that things. The paper i wrote cant be wrong cause its still hanging out and alive
Regardless of the date: if it's from versions lower than v0.31, then your seed phrase can't be used to recover the wallet to the later versions.
These are the "
release notes" that came with Electrum v0.32 and some later versions:
version 0.31 fixes a vulnerability in the key generation function.
Unfortunately, this means that wallets created prior to 0.31 are
incompatible with newer versions. We apologize for the
inconvenience. We try to keep this kind of upgrades as rare as
possible.
If you use an older wallet, you will see a message asking you to
create a new wallet and to move your balance to the new wallet.

Note that you may keep your current seed. For this, all you need to do
is to create the new wallet using the wallet recovery procedure. You
will not recover your old wallet with the new software, but you will
get a new wallet instead.
LIST OF UPGRADES:
-----------------
Version 0.34: The key derivation was changed again in version 0.34, in order to offer "type 2 wallet" capabilities.
Version 0.31: This version fixes a vulnerability in the key generation function.
TL;DR: It indicates that there were two updates that made the very old electrum wallets unrecoverable with the later versions,
seed should still work but it will generate a different set of keys hence will recover a 0 balance wallet.
Your option is to install v0.30 below, restore your seed phrase, then dump the private keys from the wallet file.
IDK if there are wallet tools that support it though, perhaps some old timer has some info.
