I've forwarded your message in the first post to
Swizzle,
DOSGuy,
Emmzee,
Jorrit and also
Hallfiry,
leilei,
Litude and
Smush the Cat.
I guess they will contact you via your e-mail if they agree to get interviewed.
Oh, I nearly forgot, I think it might be a good idea for you to re-post your message at
VOGONS (which stands for Very Old Games On New Systems), as more potential informants might be found there.
Also, have you contacted Jason Scott already? I fancy he's one of the people one would try to get in touch with first if you're doing electronic records research.
[Edit] I've just stumbled upon
this project (while browsing archive.org), I guess this is the typical professional old game preserving initiative, right?
