Cool, the first ever obfuscated Ada program!

Unfortunately, it triggers a bug in GNAT 3.15p.  I got a bug box at
p.adb:11:16.

GCC 3.4 translates p.adb but hangs when compiling abc.ads. (Or
should we take this as the appropriate error message :-)

Also, the DECsystem 10 was affectionately known as the "DEC-10" and us 
fans of that system  have celebrated "DEC-10 Day" in its honor for some 
years now. :-) Nice to know it lines up well with Ada.

Cool.  In 1982, I worked on an Ada compiler for the DEC-10
(running the Tops-20 OS).

Re: Happy Birthday Ada

I've heard rumors here of somebody porting the Gnat compiler to the 
DEC-10. I don't even know if there is still any hardware out there to 
run it on. I've heard tell of software emulators but I don't know if 
there is much of a user base. It would have been nice to see Ada running 
on a DEC-10 - back in the day... Now? I don't know what practical use it 
would be put to. Its not as if there is a truckload of Ada software for 
the DEC-10 sitting around going to waste.

GCC, not GNAT is being ported to TOPS-20, XKL is paying for the port to run
on the XKL-1.  There are still real PDP-10's running on the Internet, and
several emulated ones as well.  If you're interested in PDP-10 emulation,
see my webpage at http://www.aracnet.com/~healyzh/pdp10emu.html, it also has
plenty of links to info on the real HW.  As for how much of a userbase, I
don't really know, but it is interesting to note that XKL is rumored to be
working on an XKL-2.  For that matter there are a couple of Hobbyists
building their own PDP-10 based systems out of FPGA's.  I gather some of the
SC-20's and SC-30's are still in use as well.  All the genuine DEC CPU's and
the Flooney's seem to have been retired.

Any chance a copy of this is laying around somewhere?  I wouldn't mind a
copy of Ada for my TOPS-20 system!

Re: Happy Birthday Ada

[Marin David Condic]

Beyond pure nostalgia, I couldn't see much point. I don't have any 
software that requires a PDP-10 processor. I'd be curious about the 
logic of XKL in spending money to port to an architecture that is not 
likely to have much of a future in any commercial sense. Maybe there are 
still some PDP-10 users out there who still need some support, but it 
would seem that mostly they'd be looking for a migration path to some 
architecture with a future.

To get back on topic: This is a lesson for Ada. It is facing 
obsolescence and is hanging on to a user base that is for the most part 
looking for migration paths to something "new" with more "industry 
support". (This is what I'm hearing from my customers at least.) If Ada 
doesn't want to be a museum piece right next to the PDP-10, it needs to 
find a way of exciting and attracting *new* users and *new* projects on 
a mass scale.

For the purposes of nostalgia, there are PC emulators for the TRS-80, the
Commodor 80, and the IBM 360. Presumably, someone has written a PDP-10
emulator, right?

(At least) three people:
KLH10 by Ken Harrenstein (the oldest, and not easily available)
SIMH by Bob Supnik (actually a series of emulators of about a dozen
historically important or interesting machines)
TS10 by Timothy Stark (which according to postings about a year ago he
was adding VAX, after which he hasn't been heard from so much)

See alt.sys.pdp10 for the gory details, or a convenient summary at
http://www.aracnet.com/~healyzh/pdp10emu.html .
