I have some things in BM format, but my priority is sources available online in a format that other editors can read. I'd especially like online copies of the announcement letters, which I can't find at botsavers.
VM/[B]SE and [B]SEPP are common abbreviations for VM [Basic] Systems Extension Progeam Product, which install over VM/370. VM and the VM Community: Past, Present, and Future, presented by Melinda Varian at SHARE 89, Sessions 9059-9061, August 1997, says "1979 brought us VM/370 Release 6 and Release 2 of BSEPP and SEPP, with logical device support, the EDF file system, 128 and the first of many very disappointing implementations of CMS HELP." That matches my recollection; I ran into an incompatabily in the GTE 3277 clone, which did not update the buffer address after a RA order; the updated SEPP login code, quite properly, relied on the updated address, and it was only by tracing a second level virtual machine that I was able to diagnose (spitting nails) the problem. -- Shmuel (Seymour J.)

Yes, but the -2 level of the book has the TNLs in it. >Are the VM/370, VM/SE, VM/BSE, VM/SP, VM/XA (MA, SF and SP) and VM/ESA >announcement letters and GI manuals >available online? I can find online announcements back to VM/SP Release 2 and back to VM/XA MA. Basically, anything prior to 1980 isn't there. Several years ago there was a reprint of the VM/370 announcement, and my copy is on the wall outside my office in a building I haven't been in in over a year. As far as manuals go, I think VM/SP R6 and VM/XA SP 2.1 were the first to have electronic copies (BookManager READ). Those CDs are in my office, too. :-) Somewhere in the office are also a couple of still-in-the-shrinkwrap CP-67 or VM/370 manuals. (I *think* they're CP-67.) I can find references to VM/BSE and VM/SE, but it appears to be shorthand for "VM/370 with BSEPP or SEPP". If memory serves, I began with VM/370 PLC 3 or 4, then 6, then VM/SP R2 in college, but I wasn't aware of minor details like CDF vs. EDF. I just formatted my disks using the defaults. After joining IBM, I remember arguments in the aisle over what to do about changing the default from CDF (800 bytes blocks) to EDF (1K or 4K). I was just a young whippersnapper at the time and didn't involve myself in the deliberations of the Elders. A lot of memory cells have become non-functional in that amount of time. :-( Alan Altmark IBM ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
