Just as a matter of courtesy: consider starting a new thread when the conversation changes greatly from the "subject" line. I am a user, I'm not in charge. But since I'm posting a response, I'll change the subject line. The subject of the thread "Needed SD card solutions for museum" was about SDcard adapters to replace floppy drives on 8-bit computers. But most of the thread now is entirely about an H89 acquired which may be donated to the VCFed museum; and/or about the utility of a "Gotek" hardware product for it that emulates various vintage floppy drives with file-storage. I would have ignored the thread, except by luck. I read this list online, after the fact; not by emails. And anyone looking backwards or search, would not find those H89 interests among the subject lines, until now. The H89 by Heath and Zenith is a great 8-bit Z80 system. It works fine with original hardware and software, and hard or soft sectored disks. One needs a controller for each, with drives dedicated for each. That's how it was done in the era. But people today do like putting modern widgets and new boards on it, some use modern mass storage. The H89 and support for it, or a system to restore or to pass to the Museum, are certainly worth their own discussion threads. As for modern SDcard or CompactFlash devices that emulate floppy drives, like GoTek. I don't follow them much. But it's unusual for them to support formats like Heath's hard-sectored USART based floppy controller. It's a technical challenge, not just "bugs" to fix. If GoTek supports that better over time, that's interesting and good news. Regards, Herb Johnson retrotechnology.com https://retrotechnology.com/herbs_stuff/s_zenith.html#h89 -- Herbert R.
