[cctalk] very old UNIXes software, contact at typewritten?

Hello I have been doing a several years effort to save (very) old software for posterity, researchers, students. Mostly early 90s UNIXes, SunOS, Solaris, DG-UX, HP-UX, AIX, DEC-UNIX, some VMS software even. I uploaded some things to the Archive, and elsewhere, but I would rather get this off my shoulders, for mortality affects us all. This vanishing would be a loss, with many of these things are nowhere to be found anymore. I tried contacting the admin(?) bear at typewritten dot org, offering a few things for archiving, without results. Do any of the users here have any means to contact the admin there? I would very much like to access some of the UNIXes software there, and would gladly offer a quid pro quo. Similarly, if you have any software for Solaris (2.6, earlier) and other UNIXes, regardless of licensing status, I would be very much interested. Some things probably are lost forever though, such as Proliant PL/I, VisualWorks 2.5, Tibco S-PLUS, Harlequin WebWorks and such. Thanks in advance, and all the best Seb.
