Okay, make that an Orange Pi Zero. Probably a better bang for the buck:

Ok, I will scan that manual the next days. But in general the contents of
the 5114 MIM is contained withing the 5120 MIM.

I have an NCR labelled ADDS 2020 terminal that emulates the NCR 7930 and
7901. Has anyone a manual for those NCR terminals that describes the
control sequences? OTOH a firmware dump of the ANSI firmware for the 2020
would be fine, too.

So, faulty support logic, rather than a faulty ROS. That's encouraging.

Hi Christian,
I might have some better documentation that I just haven't had a chance to
scan yet.
I have several binders that make up the IBM 5110 System Library. In terms
of manuals enclosed for the 5110, I have the following that I can scan in
the next week or so so that you can put a copy of
Hi!
I have a Plessey floppy as part of a 11/34 system. Does anyone have info
about it? It appears that the controller is similar to the XCV21
controller.

The XCV21 manual is available on bitsavers. It
This was part of a PDP-11/34 system for radiation dose measurement at a
hospital.
Is it something general or very special purpose?

Thanks for checking. Yes, that does seem to be the more common card. As
far as I know, the 12653A was used
This is one that I haven't seen addressed.
If I'm reading a 7-track tape and writing a SIMH .tap file, what's the
custom? 6 bits per 8-bit byte, right-justified (i.e. 2 high bits
zero-filled)?
Just wondering if there's a convention established for this.

Hi Chuck,
Maybe you can answer a related question to the conversion of IBM 360 .tap files.
I see the IBM FORTRAN Scientific Subroutine Package on Bitsavers in .tap format:

How do I read/convert this back int

Thanks Al.
I did not have the insight to look in the decus library. This is exactly what
I wanted.
