Re: greater than 256 channels. I vaguely remember it was the top end of Amdahl 5995Ms which could have 512 channels. In order to use these the system had to be partitioned in 2 (not using MDF?) with a max of 256 channels in each.
Re CF links, Hitachi were known to licence the IP for some System z functions. Maybe they did this for the links.

Q: was it possible to connect Amdahl or Hitachi machines with IBM CPC using sysplex links? Did they use the same hardware and protocol? BTW: I found the following Hitachi CF link descriptions: ISCH2, ICF, ISB, ICC. Any of them is similar to IBM links (I know IBM channels, its names, etc.) Any clue? Another question: I found some non-IBM machines offered over 256 channels. How??? Note, it was definitely before XMP machines (multiple CSS). -- Radoslaw Skorupka Lodz, Poland ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
