A while back I had problems accessing a Grid 1520-286

2 pins cleared the memory.
I've seen that detail on the web pages.
Your problem would seem to
stem more from the BIOS settings and it is going to the
default setting and since the Dallis chip is dead nothing
is retained.
Exactly.
ISTR that the 12887 is a drop-in replacement.
If you want to call soldering all those pins "drop-in"
I do. Soldering is not offputting to me.
Dallas has a bunch of info on the chip. I don't
have the
URL handy.
I have those data sheets. I was curious to learn from others
experiences.
Considering all the problems and low used prices
involved. You might consider getting an old Grid 1520
which also has the advantage of an additional EPROM
slot which can contain info configuring various aspects of
the computer, including a system boot.
I wouldn't mind a Grid, but unless it has an ISA slot, preferably two,
it won't work for my application - I need an Ethernet interface for
getting EPROM and PLD data in and out, and the programmer interface.
The Compaq 286/SLT has two ISA slots in the docking station. I already
have the machine here, and I have a DS12887 coming as a free sample.
I appreciate the suggestion, but until I completely run this machine
to the ground, I would like to continue to explore using it.
Thanks,
