re: http://www.garlic.com/~lynn/2018c.html#57 The IRS Really Needs Some New Computers in the ACP/TPF timeframe, non-airlines, other res systems and financial were starting to use ACP ... prompting the change in name ... from airline control program to transaction processing facility. this was also when 308x was introducted which was going to be multiprocessor only. the problem was that acp/tpf didn't have multiprocessor support ... and IBM was concerned that all the ACP/TPF customers would move to clone vendors which were still offering faster, newer single processor systems. Eventually 3083 was introduced, basically 3081 with one of the processors removed (one of the problems was that 2nd 3081 processor was in the middle of the box, just straight removal would have left the box dangerously top-heavy). -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
