BM LCS was 8 microseconds, not 8ms. As was AMPEX's first product - about the size of a 2821 or perhaps a little longer, with a stripe of pale lights down the middle of a long side.
Data chaining was an absolute no-no - sometimes even command chaining broke. It didn't like 2305s and I think _all_ DASD opens got buffers and built CCW chains in H0. CDC also made a storage product that pretended to be LCS but cycled at the processor's 750ns. It also fitted under the console reading board. We had one of each (Ford of Europe). Got some weird results from the charging algoritm. -- Phil Payne http://www.isham-research.co.uk +44 7833 654 800 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
