Works for me. I'll be sure to pick one up the next time I see one
float by. Haven't seen them at Dayton in the past couple of years.
They used to be popular (and expensive).

For now, the Compaq 286/SLT is working for me. Looks a mess, though.
I have a picture (still in the camera) of the setup - the LCD and outer
shell are sitting above and behind the motherboard, which is open to
the world with the floppy drive off to one side and the hard disk resting
on a "Magical Mystery Tour" jewel case. The DS1287 has a crater in the
top with a 9V battery lead soldered to the rim, plugged into a lithium
cell in a ziplock baggie (which itself is soldered to the top of a 9V
battery). I don't intend for it to stay that way, but I was finally
able to a) program a GAL for the SBC6120 at last, and b) verify that
the software someone sent me for a Xander XP6007 _does_ work with the
UP600a (same ISA card, similar data files in the application directory).

Once my DS12C887 arrives, I'll be able to button it back up into a tidy
package presuming I don't have a wierd BIOS interaction issue.

Thanks one and all for help, pictures, zip files and spare parts.
