      I don't know how much of Cutler's original work was in Assembler and how much was in BLISS, since that too was a popular language at DEC. I heard long ago (around the time of VMS v3) that Cutler's original work was really crude -- he was the master of a quick V1, but his code was inefficient, so it had largely been rewritten early on. Maybe he did just use Assembler and leave BLISS to other "wimpier" coders.

      Also bear in mind that the original VAX instruction set was really huge, allowing one assembler instruction to do things that were quite long on other systems. It turned out, in most cases, that a macro of small instructions could do it faster than the VAX microcode, so instructions fell out of the ISA over time (mainly when the MicroVAX chips came out), but it didn't hurt performance. The VAX-11 was the apotheosis of CISC, a philosophy that probably was designed to help assembly-language coders.

      VMS didn't even have a C complier for years, and it wasn't much good for a long time. But it did have a lot of other strange languages. Those were the "we ain't Unix and we like it that way" days.

      The system implementation language for VMS was BLISS. The MACRO-32 assembly language was based thereon. The VAX hardware architecture and the VMS OS were co-developed and joined at the hip. As VMS evolved, portions of the OS were rewritten in C. When Alpha came along, the microcode that tied VAX to VMS was obsolete... VMS knew nothing of the Alpha architecture. Hence a hardware abstraction layer was used as a go-between. That was PALcode, or Privileged Architecture Library code. PALcode enabled VMS developers to rewrite MACRO routines in C. Not exactly the easiest of architectural ports, and it consumed the resources of the majority of the VMS Development team. Alpha to Itanium wasn't an easy port, but it was accomplished by about 25 developers over the course of 43 months. Far fewer lines of code had to be changed, and there was no code freeze... VAX/VMS V5.4 was the code freeze point for Alpha/VMS; while the Alpha porting team turned VAX/VMS V5.4 into the first Alpha/VMS release, the VAX/VMS developers kept on developing VAX/VMS. So VAX/VMS had more functionality (absent the 64-bit support) than did the initial Alpha/VMS release. It took a number of releases to bring Alpha/VMS up to feature 'n function level of VAX/VMS.

      Haven't a clue if VMS was designed with clustering in mind right from the get-go, but VMS started shipping in ~1988, VAXcluster software materialized around 1983-84. Clustering definitely preceded VMS V5.0, the 5.0 release was all about a modular kernel and SMP support and security enhancements.

      Dave Cutler did not write or design VMS, he was responsible for VAXeln, a run-time version of VMS. He then went on to develop MICA, the OS intended to run on the PRISM hardware architecture. PRISM was killed because the hardware existed, MICA was nowhere near ready for prime time, or even initial boot time.

      MICA was designed to be a superset of VMS that reduced VMS limitations and expanded its capabilities. Cutler went to Microsoft the day after the PRISM project was cancelled, and he took the MICA code along with him. Cutler went on to develop NT, and DEC discovered that portions of NT were identical to portions of MICA, right down to the comment lines.

      I'm not a lawyer, but I know enough about intellectual property to realize that NT contained a lot of DEC IP which DEC did not legally convey to Microsoft. DEC's IP lawyers knew that DEC had been ripped off. DEC knew that filing a theft of intellectual property lawsuit against Microsoft would be an exercise in futility, as DEC had far fewer lawyers and far fewer financial resources than did Microsoft.

      The end result: the so-called "Alliance for Enterprise Computing." Big win for Microsoft, massive blunder on DEC's part. DEC's CTO, whose initials were BS, jumped at the first offer Microsoft put on the table. Bill Strecker knew a lot about computer technology and packaging, but he didn't have much in the way of negotiating skills. He jumped at an offer that sealed the fate of Alpha back in ~1994 or so.

      Under the terms of the "deal," Microsoft agreed to endow Alpha with Intel parity on the server side, but not on the desktop. VMS minus desktop productivity tools (trivial things like the MS-Office suite) couldn't compete in the high-volume Wintel space. DEC unilaterally ceded a vast addressable market for Alpha and VMS. FX!32 binary code translation and emulation couldn't undo the damage DEC did to itself.

It had features like privileges for just about everything that you can think of - much finer granularity than all or nothing. It had a fairly well developed system of ACLs that could be attached to operating system objects other than files (unlike Unix, not everything is a file in VMS). One of my favorite things to play with was logical name tables (something that doesn't really have a Unix equivalent).

    Security suffered from the transition because Vax/VMS had KESU shells and the Intel platform didn't support the Exec mode. Each shell had specific instructions that could only run in that shell, and it's own discrete address space.

    as a result of pretending to be Neill Clift) and forward to Digital.

    As for the CCC, Mitnick installed the "show user 0TTO/1TTO/2TTO" bug
    in many VAX/VMS systems, so that he could remain invisible while on
    as well as bypass the "pre-login" password required of dial-ups. He
    also tricked dial-back systems (where the modem calls you back at a
    pre-set phone number) by adding call-forwarding to the home phone of
    authorized modem users, thus intercepting the call-backs.

    Through the availability of source code, technical support (yes, we
    had access to DEC technical services - all it took was an entry in
    their database of support customers) and systems, we were able to
    study several more weaknesses and eventually code a LAT exploit
    which, to-date, remains unpublished.

    Prior to all this, by the way, Mitnick was breaking into RSTS/E systems
    with impunity. If you had dial-up access, there was basically no way
    to stop him... no social engineering required! That really irritated
    me, because I lived an hour away from work and emergency dial-up was
    not an option.

    I actually still have LA120 printouts of some of these exploits... and
    answering machine tapes of mitnick leaving me messages about the latest
    systems he was able to compromise. In the early days, he'd even steal
    other peoples' RSTS/E cracking programs... Like Dave Kompel's tangled
    syscalls to spin the kernel into giving you system privilege. I think
    I still have a copy of that in storage somewhere.

    By the way, all this is just the proverbial "tip of the iceberg."
    There are a lot of other things from Mitnick on those answering
    machine tapes that never made it beyond me... some of his other
    "hobbies" involved the DEA, the MDC (Metropolitan Detention Center),
    Magic Mountain's debit card terminals, and oh... the issuing of
    "patches" to select VAX/VMS customers on upgrade support contracts.
    The patches were delivered in the geniune DEC patches box, on the
    correct media for those particular customers. Needless to say,
    all those customers had dial-up (or network) access available.

    None of that even covers the period of time when Lenny DiCicco worked
    at (what was once) PacTel Cellular as their database administrator (in
    Orange County, CA). Once Mitnick found out, hundreds of thousands of
    ESN's, MIN's and the associated customer names, billing info and social
    security numbers were compromised. Since we had the assembler code
    (complete with comments) to the Novatel PTR-825 as well as the compiler,
    Mitnick was able to remain "invisible" and "untraceable" for years until
    he pissed off Tsutomu Shimomura. After all, he had an endless supply
    of ESN/MIN combos, and could enter them into the PTR-825 directly
    thanks to some custom firmware hacks.

    Perhaps I should write a book on what really took place "on the inside"
    complete with printouts and WAV files. Maybe in another five years,
    after I retire, I might.
