- Apr 1, 2008Ray,As an old Burroughs guy, you probably don't want to hear this but Linux has some support from a big gun. IBM offers Linux on their mainframe systems. Even though I too am an old Burroughs guy, I think that is pretty big gun support.Bill AB3DT-----Original Message-----

Subject: RE: [softrock40] Re: SD Software?Hi Terry,Thanks for putting this in the proper perspective - I agree on everything you have said except for one thing. I have been watching LINUX try to grow to a full blown OS for many years and while it is superior for specific characteristics I don't think I will hold my breath until it matures. I have my doubts that it ever will - it seems to lack the management drive that it takes to make a single entity that does it all. Right or Wrong if it can't at least do what MS OSs (including device support) do then it will never be a big box competitor.I hope I am wrong about LINUX because I truly believe it could be king of the hill with the right direction, management and stability, but that has yet to happen.73, Ray, N0FY

Regarding SDR on older computers: try simultaneously running a
graphical user interface, and the DSP code necessary to decode and
display CW or SSB on a 386 or 486. Without a dedicated DSP chip, you
are in for a long wait. Over ten years ago, I wrote DOS-based code
(in Turbo-C) that displayed an audio spectrum analyzer in a DOS-based
VGA graphics display. All the DSP was done in either a homebrew
Motorola 56000 board, or an EVM, with DMA data transfers over the old
PC bus (homebrew), or fast serial port(EVM).
I don't want to do that again. But, if you are staying DOS or Win-
98, kiss the PC doing DSP goodbye. I still have three Moto 56000 EVM
boards that I'd be glad to sell.
Regarding Linux: There is some movement afoot there with SDR. There
are a few programs that will work. Again, you must do a hardware
upgrade to get the processing necessary to do DSP and on-screen
I also have a couple 486 computers with Win98, and Win95, and DOS.
Just in case I ever want to run my 56000 audio spec analyzer.
But, I also have a working IBM 5-slot computer, and a spare.
And, I have a working IMSAI CP/M system with Heath H19 terminal, and
8-inch drives. I boot CP/M and run Wordstar every once in a while.
How about a nice game of chess? Or the CP/M user-group Adventure?
I also have two Altair 8800s, and an Altair turnkey (no front panel),
plus a bunch of S100 boards. No power to them in about three years.
I don't expect these computers to run SDR software either.
And, I can still erase and burn 1702A to 2764 EPROMS. Go figure.
Don't get me started with software. From CP/M, to DOS 1.x to 4.x, to
the original flight simulator. I even had the paper tapes for Altair
4k and 8k Basic. Anybody remember Lattice C, or Run-C? Or the CP/M
But native SDR on a 4MHz Z80? Probably as likely as on a 266MHz 486.
