It has been a long-time (almost 40 years now) since I worked part-time at an IBM dealer,
BUT attended ALL the IBM hardware training (and later as an early corporate PC center
manager), including the wonderful OS/2 presentations.
I also selected that IBM model for my father’s business software, which required IBM
hardware in late 1980s.
Most of my documents went to on-line resources, like Tomáš Slavotinik (Ardent Tool).

IBM PS/2 model 80  : “Wrangler”
8580-071 Type 1 Planar
The Diagnostic Disk and Support information for that model can be found there.
That Disk and a Fresh battery (as required) is a Good Start.
I acquired an IBM PS/2 Model 80 (8580-071) today and am looking for advice on what I
should do to check it out before, during, and after applying power for the first time.
I'll try to get some pictures if anyone is interested.
The label near the power switch says that it's an 8580-071. I have no idea how that
compares to the hardware that's in it.
There are two full size (5¼) hard drives, the controller card. I don't know what type
of drives they are yet, they look to be MFM / RLL like in that they have the common cable
and a per drive cable.
There is a video card that has a daughter-card in the same slot like a thick sandwich.
There is another card that I don't recognize. The card doesn't have any external
connectors and it looks like it takes multiple (approximately 4"x4")
daughter-cards. I am wondering if this is a memory expansion of some sort.
There are two of what I believe are the memory boards between the back hard drive and the
The battery is still in the system, but I didn't see any corrosion and it's away
from the motherboard.
There is also the degrading black foam used for air ducting. Blech.
Q: What things should I do as part of checking out this system. I'd like to
eventually power it up and see what is on the drives (if they will spin).
I need to physically clean it with a damp rag and get some pictures of the system.
Please share any pro-tips / gotchas / etc. that you think I could benefit from knowing.
Thank you and have a good day.
