I remembered Capitol HUG had huge software libraries for Heathkit H8, H88, H89, Z90, H/Z100 (non-PC compatible). It seems to have disappeared. I tried to contact them, but no one answered. It was many years ago. I do not know if anyone collects the files into the archives. If it is lost, then it will be a setback for SEBHC. This incident is similar to the S-100 system such as Technical Designs Labs, IMSAI, ALTAIR, Northstar, and many others. Many users abandon and use IBM PCs and Apple Macintosh. Less than one percent of users remain with the old system, but 99 percent went to the new system. The same incident with BUSS, Sextant, Kilobyte, Bytes, many outstanding magazines went away.
I collected a lot, but when I moved from New York to South Florida. Many things were stolen while moving. The detectives arrested several movers for theft but very little recovered. I remembered I had 24 boxes filled with vintage magazines and eight boxes secured with binders filled with 8" and 5.25" diskettes including hard-sector types that had disappeared. I wish that I have H.G. Wells' time machine and go back to recover my things.
