OT: Good place to ask about XP memory problems

[Bob Eager]

On benchmarks, yes. The barrel shifter made a few things faster, but overall it was a bit disappointing.

And the correct name is V30.

[Bob Eager]

REXX and C for me!

I have seen plenty of portable code where the portability is done with compile time switches to compile different code. If that's what you deem to be portable then I guess you are correct.

Motorola have. Look at some of their VME boards (well the ones five years ago as I haven't looked at the recent ones).

Just because you can't do it doesn't mean others can't do it and will do it if there is a good reason. Intel made some very nice devices that Motorola never made. You either used the Intel ones or didn't bother making the board.

[dennis]

That's why we had our 8086 design running before the PC came out.. you couldn't get 8088s and you could get 8086s.

Its like FPLAs and FPLSs from Signetics.. I liked them and deigned them into one of my boards, others doing other boards copied the design.. we then ordered all the output of FPLAs and FPLSs that Signetics could make.

As it happens it was about then that PALs appeared and everyone else resorted to PALs. It probably saved AMD from bankruptcy as FPLAs and FPLSs were far better than PALs so why would anyone have used PALs?

Well they waited until they could get 8088s.

Did you ever try too buy a few thousand 68000s at that time?

[Andy Champ]

You are the first person I have ever heard say that.

Most of my career has been 8086 family; I hate it. Barring the iapx432 it's the nastiest instruction set I've ever used.

[dennis]

No geof you just can't read! You think you can read but get it wrong.

I am glad. I would hate to have anything in common with you.

You are missing out, it would be the most exciting thing you have ever done.

[dennis]

Who's C compiler? C compilers were around when tapes were being used. You didn't load the tape three times to do three passes.

[ARWadsworth]

Followed by observing speed limits?

[Tim Streater]

Beats the IBM 360/370, does it?

[dennis]

Oh no it isn't portable. You would have to use one of the C libraries to store the data to make it portable.

Most of the portability issues have gone because the hardware has gone. Lets face it with nearly everything running on Intel CPUs it all appears to be portable.

However it was claimed to be portable even in the days where there was different endianism, 7/8/9 bit bytes, 7/8/9/12/16/24/32 bit words, etc. and they are just the ones I recall.

It's kept me in business for most of my 22 years - SuperBeam 1 was written in Turbo Basic, 2 in Turbo Pascal and 3 & 4 in Delphi

[Andy Champ]

You never used it did you?

I had to write a memory test to run on '286 machines, and our test environment was real mode. So in and out of protected mode to get to the extra memory.

I got a headache every day driving that damn chip. Bill Gates was right when he said it was brain damaged.

Of course the '386 and everything since has had a segmented MMU on top of the paging system. And how many people have used it?

Andy

[dennis]

Oh yes, very portable just use different functions on different machines. For example

"The sqlite3_value_text16be() and sqlite3_value_text16le() interfaces extract UTF-16 strings as big-endian and little-endian respectively."

It shows what I was talking about quite well.

[Bob Eager]

And of course there was no documented way to do that...once you'd entered protected mode, only a reset would get you out again. Leading to some very weird circuitry and BIOS code in the PC/AT to do just that.

They basically had a brief to support all current popular memory management models. So they did.

[Tim Streater]

No, it just shows you know nothing about UTF-16. And that you've chosen to ignore everything else.

[Bob Eager]

For the best, most orthogonal instruction set, you still can't beat the PDP-10...

[Bob Eager]

Your inexperienced opinion.
