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

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
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
Just wondering if there's a convention established for this.

Thanks for checking. Yes, that does seem to be the more common card. As
far as I know, the 12653A was used

Is it something general or very special purpose?
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
The XCV21 manual is available on bitsavers.
I might have some better documentation that I just haven't had a chance to

So, faulty support logic, rather than a
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.

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

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

I thought I did, but what I have is the HP 12845B Line Printer interface
card, for which I could find the documentation. Unfortunately, looking at
the schematics, it does not seem to be based on a 12566B interface. Reading
some more, it is meant for the 2607/261x series of printers, which
