I've just built the old ircII stuff... and that was involved to say the least. the University of Wisconsin version of 4.3 BSD seemed more usable as its got some SUN magic in there like NFS and various other cleanups ... I haven't looked at irssi as I'd imagine it'd be ... involved.

embedded libraries for PDP-11, was Re: [HECnet] DECUS RSX C compiler

On 10/22/2012 02:56 PM, Jordi Guillaumes i Pons wrote: The main barrier to a bare metal binary, or for that matter a not so bare metal one, is the supporting libraries. I did a *really* crude hack job on newlib to give me just enough bare metal support that I could run the GCC test suite under SIMH. But that certainly isn't enough for real bare metal. A pdp11 port of newlib would be a nice project. I tried... But it is too big. I think I got a fatty library because I selected the floating point support... I tried to use sprintf() and it didn't even fit into the PDP address space :(. The printf() family is GIGANTIC. In newlib there are non-FP-enabled versions of those functions; iprintf(), siprintf(), etc. They are much, much smaller than their floating-point counterparts. I suggest you try again with that and see where things land. I'm using them on ARM7 with great results. Granted that's got a much larger address space, but my resultant binaries and stack utilization are still pretty small. The 2.11BSD lib looks leaner, and I am using it in my pet OS project (I pick the pieces I need "on the run", I have not done a complete port... yet). If the above suggestion doesn't get you anywhere, perhaps avrlibc could be hacked into a PDP-11 library. All of the hardware support will have to be ripped out of course, but there are nice tight implementations of generic library functions in there. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

I need to figure out, watt for watt, if it's more expensive to heat with electricity (via big iron in my case) than natural gas here in western PA USA. I suspect gas is cheaper, but am not certain, and I don't know the transfer function of the boiler in my building. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Bad Bug in Windows Version of DECnet Router

by robert.jarratt＠ntlworld.com

Just in case anyone is trying the router on Windows, I just fixed a bad bug that causes heap corruption. The linux version is unaffected. Regards Rob
