Nice setup and some great suggestions. Thanks for sharing.
I don’t see one but I presume you use an RS-232 switch to share a single terminal with the three H8 systems?
The 8” heath floppy unit is their second generation 8” unit right? (Z207??) not the 47 (that was bigger with vertical drives that were unreliable as I recall?)
Your notes say that there are two 3.5” drives mounted in an H19? Is it really an H89? Or are you just using that as a convenient case/power supply for the drives, which connect to one of the H8s?
I had an old 4-way serial switch but the mechanism that “clicked” it into each position was broken (plastic piece) so I ended up just tossing it and buying a new one. Ironically at VCF there were a number for sale that I could have bought. Useful to have.
Interesting approach to “downgrade” an ’89 back to a ’19 and use the extra power and space for two drives!
It sounds like you’re very much still using floppy drives and disks. But your original re-engineering of the Z80 board included a GIDE interface. Is that still how you do hard disk op’s? still using a physical hard drive or one of the IDE-to CF/SD emulators?

When I get time I'll get a IDE solution up and running thanks to Norby for the Z67-IDE+
I have been cleaning up all day my computer room. I put into the mobile cart my original H8 computer, H19 green monitor, and H17 floppy drives chassis. My original H8 system is in pieces as I used to debug boards and I need to put it back as it was back in the 80’s. I’m ordering a second mobile cart one to put in there a set of H8’ systems: one for debug and one for development of H8 boards.
On the H17 three drive chassis: the 5.25” floppies are dead, so at least I have two 3.5” floppies in there. So, I will need to divide the H17 into three sections: 2 floppies for the H17 controller (buy in eBay a 5.25” floppy drive + 3.5” floppy drive), 3 floppies for the H37 (2x 3.5” floppies + 1GOTEK), and 1x Z67-IDE+ for the H67 controller. I asked my son to 3D print a box for the Z67-IDE+ to add into the H17 chassis as a 5.25 half height floppy drive look alike.
Thanks for the recommendation,
My original H8:
