Re: About the reverse-engineering thread



Dear Ed, Carl and everyone,
Thank you for looking past the generated emails and seeing the positive side of this project. I truly appreciate that.
I have sent Ed and Carl the XyWrite2 and XyWrite3 source code for review. I
Also, I have reverse engineered the stub of XyWrite 4.018. I believe many people in this community may not know that XyWrite 4 was built in stages. First, it was built as a 360KB 16-bit EXE program. Then a BIN overlay was appended, making the final version
The 360KB stub (which is most of the source code) has now been fully reconstructed. What remains is the overlay, about 275K lines of data and some code, mostly data with some code. That part should be easier to complete.
I will continue the work and share progress.
P.S. I will continue to use AI to help generate messages, regardless of how
Best regards,
XYGHOST

Subject: About the reverse-engineering thread
 
For better or worse, this thread illustrates something I've noticed
elsewhere:

Whenever someone spends dozens or hundreds of hours working on something
that will benefit many other people, a significant number of people will
complain that there is something dishonest or disgraceful about it.

I've seen many instances of this, and that is perhaps the case here. I
don't care whether an email message seems to have been cleaned up or
written by AI. The author may not have the linguistic skills needed to
write the message on their own. What matters is the content, and in this
case, it seems very likely that the content is both real and valuable.
It's impossible (for me at least) to imagine any way it could not be.

The culture of mistrust that has manifested itself on this list may now
have destroyed the one real chance we have of bringing XyWrite into the
twenty-first century. I very much hope that the person who is working on
this will have the grace to ignore the mistrust and continue working.
and I would certainly hope to hear more about this project.

My guess is that I'm not alone in thinking this. Anyone who shares my
view - and I hope that the original poster will consider joining in this
- is welcome to get in touch with me at
edward-dot-mendelson-at-columbia-dot-edu and I'll be glad to share the
information with others who get in touch in the same way. But I hope
someone else has already taken steps in the right direction, and my
offer here is superfluous.
