Ton's site just seemed to vanish. I'd gone there one weekend to get an Ariane V, went there a few days later to get the "new" Russian ACTS and the site was no longer available.
BTW, Ton's Apollo and Command Service Module prompted me to hunt down your version. I've got them printed, but the construction has me intimidated. I'm still going to try it though.
Looking forward to a Skylab manual
