What ever happened to Tandem and NonStop OS 2036

Actually, if memory serves, the PDP-8 actually pre-dates the 4004. So it would be more accurate to say "...given that there were no such things as microprocessors at the time."

Oh, GMAFB. No PDP-11 model was ever bigger than the smallest configuration of a PDP-10. The PDP-10 (later called DECsystem-10) was a mainframe -- such a well-designed mainframe that it was sold as an entirely new system (called the DECsystem-20) without any significant hardware changes, only a change in the operating system (TOPS-10 to TOPS-20).

Hyperion, the developer licensee for OS 3.9, is possibly French-based. ICBW.

Osborne didn't make PCs. They made the Osborne 1 and the Osborne 2, and then made the mistake of telling everybody how great the Osborne Executive was going to be, and end off their Osborne 2 sales, which dried up the revenue flow.

As long as DEC kept building PDP-11s, they were producing LSI-11s -- and they kept building them for quite a while afterward as spare parts.

Um, no. The 68000 didn't appear in mbutt-market desktop computers for quite a while after its introduction. The 68000 was released in 1979, and it was 1983 before the Lisa appeared, and 1985 before the ST and the Amiga. That's 4 to 6 years.

But even though the 68000 required a lot of support logic to be used in a mini or a workstation, it was still compebreastive with the PDP-11.

timeframes right. By that time, the Jupiter project (DEC's development for their next big mainframe -- IMHO probably would have wound up being called the DECsystem-30) had already failed and the need for a new mainframe to replace the aging PDP-10 was being addressed.

I could be totally wrong about my timeframes; I'm deliberately trying not to tie down any specific dates for DEC events, just saying that 'by this time, this had happened,' in hopes that I can mitigate the damage caused by my lack of memory of specifics.
