Were you discussing IBM cartridges from the 1970’s recently? I just registered and thought I read it somewhere. Thank you and apologies if I am intruding.The subject line says it all.

Thank youSorry, no, it was not me.

Not that I know - with the exception of the emulator. Just having a proper place to talk about them brought the discussion itself.Just curious with all this new attention. Is there any new software for the 5100 family?
I think thats probably true. I got my 5120 years ago from another member for a very fair price...I think most of the interest is coincidental, though --- every so often someone gets their hands on one of these cool machines and likes to talk about it.
COMMUNICATIONS CONTROL GENERAL:
The Communications Adapter Feature includes communications interface hardware and licensed programs that enable the System/23 to communicate using either asynchronous or binary synchronous protocol. The physical interface for asynchronous communication is EIA RS-232-C/CCITT V.24-V.28 and transfer data is via ASCII code. The physical interface for binary synchronous communication is EIA RS-232-C/CCITT V.24-V.28 with clocking supplied by the modem. Transfer of data is in EBCDIC and EBCDIC transparency modes at speeds up to 4800 bps. One of the IBM modems, 3863 (2400 bps), 3864(4800 bps), 3872 (2400 bps), or 3874 (4800 bps), can be attached to the Communications Adapter Feature.
COMMUNICATIONS: Two licensed programs, Asynchronous Communications and Binary Synchronous Communications, allow the System/23 to communicate with selected IBM systems and devices. Both consist of communications access method support, a set of communications customer support functions, and a facility for user-written communications programs using System/23 Basic. In conjunction with the communications access method, the Asynchronous Communication Terminals customer support function provides the user with an interactive interface to perform asynchronous communications. Features of the Asynchronous Communications Program include:
• A data transfer function, making System/23 TTY compatible. This function uses start-stop discipline and permits the user to transfer data using the ASCII translate table and the Asynchronous Communication Terminal function of the licensed program.
• A code translation table is provided to convert Datamaster internal EBCDIC code to/from ASCII code. Other tables may be built by the user.
• Provides the operator with an ease-of-use interactive function that leads the user through a step-by-step procedure using prompts and responses for defining and establishing communications and for performing other TIY functions.
• The input/output devices supported are the keyboard display and printer.
• Provides a facility for the execution of BASIC language user-written programs to perform data transfers. Communications with the following IBM systems is supported:
1) System/370, Models 135-168,3031, 3032, 3033, 3081,4331, and 4341 via VM/370 (full-duplex, switched facilities)
2) Series/l (EDX, RPS) (half-duplex, switched facilities)
3) Datamaster (full and half duplex, switched and non switched)The communications customer support functions can perform the following data transfer functions using the Binary Synchronous Communications Protocol in conjunction with the communications access method:
• Transmit batch data
• Receive batch data
• Inquire into a host system and receive batch data
Many things need to be double-checked in this system. Myths need to go down and replaced with facts.That's why I said this needs to be double checked.
You have been entrusted with a very special system. Taking care of it may be enough. The duty is yours to handle it down to the next generation when the time comes.I think thats probably true. I got my 5120 years ago from another member for a very fair price...
But now what do I do with it?!
Fair enough but it takes up the space of a mini-fridge and weighs as much as a small person.You have been entrusted with a very special system. Taking care of it may be enough. The duty is yours to handle it down to the next generation when the time comes.
We all have our roles in the big scheme of things. Ours is to preserve the history of our profession before it is reduced to scrap. In the last 50 years computers have radically changed how do we live and we should consider not only the technical side but the human one too.
