First off, thanks for the reports on the ZuluSCSI!  It’s great to see so
many options in the marketplace for replacing dwindling stocks of spinning
disks.

For the DS1287, I can report that the replacement board made by Glitchworks
and sold on Tindie works well.  It was easy to install on my 927LX main
board, but of course does require desoldering the old chip and soldering in
the Glitchworks product.  Once that’s done you just have to clear the chip
contents with an ISL utility and set the date and time.  I posted about
this a while back when I was going through this process, just search for
DS1287 in the archives.

Here’s a link to the Glitchworks board

Hope this helps.
