Hi
Hi,
As a proud owner of a P390 system, I've collected some questions that i
wasn't able to find answers to at [1].
Welcome to the club.
If you have knowledge regarding those or related systems, I kindly ask
that you read through the page. Maybe you can shed some light!

Hardware
1) It's my understanding that there are some companion cards that go
with the processor card.
- Bus & Tag
- ESCON
I think you're also missing any information on the older ISA card sets.
E.g. the ISA System 370 CPU+RAM card that goes in the PC/370 and the likes.
Do the R/390 et al. cards have different FRUs? Or is it the same
hardware with different software; OS/2 vs AIX?
2) I would guess where and / or when 08J5941 and 08J5882 were made.
3) I have no idea. Debugging indicator for the card? Maybe this
speaks to question 2.
I wonder if there is any relation to the LEDs with any bits of the
Program Status Word.
OS/2 Software
I've used my P/390-E with OS/2 4.x and ArcaOS.
AIX Software
I have no idea of #1 nor #2.
I wonder if part of the difference with OS/2 console vs AIX console is
related to the fact that dtterm / aixterm / xterm are inherently text
(especially with the version that I think they are). As such, some of
the more special characters that are used in the status line to indicate
connected, waiting, offline, etc. probably don't display as cleanly in
pure text. Remember that the console in OS/2 was it's own GUI that did
it's own terminal emulation and could thus support special characters.
You can see similar with the difference between X3270 and it's console
counterpart C3270 from the same source code.
LIC
I have no idea about versions of the LIC.
