Man, these things are annoying.
All of the bands are bad, and they leave residue on the spools.
There are no EOT BOT holes on the HP tape, and the drive locks
the cartridge until you 'unload' it, which spins to the EOT soft
region. Well, guess what, they leave the tape in a position where

Gentlepeople,
Once in a while people ask about GCC. It has long had pdp11 support, but it
hasn't received much attention. Recently I've done some cleanup on it, and
some more is in the pipeline.
One notable new feature is that it can now produce proper DEC Macro-11 syntax
output. It has lon

Hello all - I have created a mailing list for VCF Midwest news and
announcements. You may already get your show news here or on the
forums, but it will be useful to us in the future to have as many
interested people as possible listed in one place. So, if you'd care
to take a moment to drop an em
Great news, Paul!
I'll try and give this a go this weekend.

hi
is there any chance someone has a working gcc-ada compiler? for
- Linux/MIPS (big endian, MIPS3, MIPS4 or MIPS32)
- Linux/HPPA2
I have successfully compiled gcc-ada for SGI_IRIX (MIPS4/BE)
but ... every attempt to create a cross-compiler(1) fails
on HPPA I have never seen an Ada compiler

Al,
thank you putting so much effort into reading these old Tapes. Really
appreciate it.

inside PIC32 there is a MIPS32-R2 core, but the toolchain is not OS-profiled
it's metal bare (without an OS, and in this case Linux requires a lot
of considerations)
