Hamfest schedule will determine whether I can make it or not, I had a full day at the hamfest yesterday.
I just didn’t feel like making it to the workshop today, sorry.
 thanks for the invite
I’ll try and make next one if I can

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.

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 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.
