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: http://bitsavers.trailing-edge.com/bits/IBM/360/360A_CM-03X_Scientific_Subr_Pkg.zip How do I read/convert this back

SIMH .tap file 7 track?

2017-07-11 Thread Chuck Guzis via cctalk
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. --Chuck

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. https://i.imgur.com/NxGPBFN.jpg https://i.imgur.com/NOg7WfZ.jpg https://i.imgur.com/HnhmO33.jpg The XCV21 manual is available on bitsavers.

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

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. Christian

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
