Thanks again nc50lc. I raised an issue
https://github.com/spesmilo/electrum/issues/7893. The responses have been very interesting although somewhat disheartening. They're saying that prior to version 2.0 Electrum used a fixed word list; and if my word list is not in that list it could not have been generated by Electrum; so basically I must have used a different wallet to Electrum.
It's pretty much everything we said in the first page: the dates in your memory are off.
The issue is you're using 0.3 while the version that doesn't have a word list was the initial release up to a couple of commits.
Version 0.3 is way past the version after a fixed word list is introduced so your unique seed phrase wont work there.
A fixed word list was only introduced in this commit:
https://github.com/spesmilo/electrum/commit/93c27a62d47d9aab6b5502999df2ff184482e1e0Prior to that, Electrum will ask for a 20-word-minimum "
seed phrase" or "
passphrase" in the earliest versions. (
check my screenshot above testing the first commit)
So, you should only be trying the versions prior to that commit, only the last page of the commit history.
