I have worked on enough of these to not take chances. It's a pain if you
have to guess. If you can't get into the hard drive you can't read the
config.sys and autoexec.bat for clues, you can't run a diagnostics as
easily. So it's just conservative, my approach. But yes you could just say
this is a stock system I have the ref disks I don't see any need to worry.
Sounds like you have worked on these enough to know and that's good enough
for me.
That's my point, at least try the system see
if it works as is, but
assume the battery is just about dead if not completely. May have
enough juice for one or two more boots. so get the info out of it
you can.
I'm curious, what do you think /might/ be about to be lost that's of value.
Based on my understanding, the system seems fairly stock, an IBM ESDI
controller, an IBM graphics controller, and what appears to be an IBM
memory expansion. I naively assume that re-configuring those from the
ground up would not be a problem. Of course that's predicated on a
reference disk with the proper ADF files.
I'm assuming that said reference disk, ADF files, and possibly option
disk can be acquired.
THis goes without saying but don't remove the battery!

The chances a model 80 will smoke out or catch
fire is less enough
to make that a secondary concern.
Thank you for that.
no caps like that, this is an IBM.
Cool.
I didn't think so. But it's been a long time since I've worked on a
computer 25+ years old. I'm more cautious now than I was the last time
I did so.
Even if there is stiction you should still try to
boot and capture
as much info as you can first before you replace the battery.
Based on previous experience with PS/2s, and re-configuring from the
ground up, I'm not too worried.
I'd be likely to acquire a new battery and another power source to
connect to the battery terminals while I replace the battery.
That being said, I should take my volt meter and see if there's anything
at all. If it's dead, then there's not any point in hurrying.
I used to work at IBM when they sold these.
