I would love to come to the workshop tomorrow but I can’t.
I will be selling my off some of my stuff up at the hamfest in Succasunna, New Jersey on Saturday.
I may be able to try for Sunday but not sure yet.
It would be nice to see these systems.

Otherwise I offer to look at the Museum's warehouse of H89's and assess them while Jeff does his work. I'll bring some component parts but it's likely Jeff will bring what he needs. I assume he can do some repairs, and likely he'll bring his own diskettes along with the ones he acquired. If not, we can work with what's available. There's variacs around and that's a good tool for dormant computers.
> The Heath H89 is a good example of early 1980's Z80 personal computers, and noteworthy as a Heath product. For those unfamiliar, Heathkit was a premier electronics kit company for many decades, in the mid-20th century where one could make a career and job from servicing electronics. They provided test equipment, radio amateur equipment; their products were both learning tools and teaching tools. The H89 was a good business computing system, with support from local Heathkit stores and local computer stores of the era. The Z-100 followed the H89 and became a noteworthy MS-DOS computer and an S-100 system; the H8 was an early 8080 computer before the H89.
> They are all entirely serviceable today as is much 1970's 1980's equipment if one has digital-component-level skills; that being my interests. They ran CP/M and Heath's HDOS and have VT52-class graphics, so there's lots of software they can run. For some time, SEBHC folks have made new Heath-class boards, so that generates 21st century interest.
