Yeah, I know. I'm using that thing in the 4000/60

DS1287A
Poking it around it looks like the DS1687 is reasonable replacement.

The 1287A was a replacement for a Moto part used in the IBM PC: There is an app note on how to replace it, which is what made me look at the DS1687.

Dallas semi says the 1687 is SW compatible with the 1287A which I think is what you need to care about and then maybe a little HW hacking, although it looks fairly close. Needs to check any timing differences and the name of the RW/WR pin is different - but they >>might<< work the same way (might also need to be inverted).

Right now if you search for DS1287A in their web you get nothing.
Well then that one may have been discontinued. I bet there are still
quite a few of them around, though. (one can readily buy brand new
7400-series TTL, for example...and I'm not talking 74LS!

Sigh. The misinformation that keeps spreading. The problem is for specific older VAXen. I think it's even only specific 3100 models. And the problem is just that the boot rom uses a more restricted disk block addressing, limiting the booting to disks of less than 1G. (Actually, you can boot from larger disks as well, as long as the boot rom don't need to read from anything above 1G.)
Well, I'm in shopping mode now. Any suggestion for a reliable EU shop to get these kind of drives at a reasonable hobbyist price? I have done a quick google work and I have found http://www.scsishop.co.uk which seems to be pretty decent price-wise. Amazon also lists some american sellers, but the shipping costs are bigger than the drive prices :). And ebay is... well, ebay.

If you can copy it to your default DECnet directory I can
pick it up
from there.
