Intel-free...

Post #20,351 by inthane-chan 12/5/01 1:47:58 PM Reply	Intel-free... ...since my P-133. RAMBUS's claims are pretty piss-poor - this seems more like a way for Intel to weasel out of a bad deal, than any actual divvying up of the market. The patents that RAMBUS acquired were gained in direct contravention of a legally binding agreement they entered into a while back - putting them in breach of contract, and probably nullifying their patents. They're still Evil, and should be Staked. Go AMD! "He who fights with monsters might take care lest he thereby become a monster.

If something is a direct copy, sure, sue the hell out of the other company. My only Intel system is a P-III laptop. But, if I buy another laptop. I'll make sure it isn't Intel. Tony
Post #20,375 by Meerkat 12/5/01 5:05:20 PM Reply	MeToo (tm) come to think of it. Last Intel chip I bought was a P166MMX. Since then it's been AMDs and PowerPC. On and on and on and on, and on and on and on goes John.

Post #20,458 by Silverlock 12/6/01 8:44:54 AM Reply	Don't think so. I'm pretty sure it was a Z10. Company name might have been Zilog? I think they make chips for embedded products now.

Post #20,464 by broomberg 12/6/01 9:24:38 AM Reply	Z10? Not Z80? Z80 were in CP/M machines. A Google search for "zilog z80" returns 4,630 pages. A Google search for "zilog z10" returns none. Are you sure it was a PC compatible?
Post #20,465 by Silverlock 12/6/01 9:47:54 AM Reply	Am I sure? Yeah, it was a PC clone. What I'm not sure of is the name of the chip and/or the company that made it. I am positive it was not a NEC chip though. The Z80 sounds vaguely familiar. I do remember that the chip was faster than a comparable Intel chip. 4.77 vs 8 MHz? 8 vs 10 MHz? You know your getting old when you can't remember what you once used for bragging rights.

Post #20,481 by a6l6e6x 12/6/01 12:03:22 PM Reply	Well, the V20 was compatible with Intel 8088 used by IBM... i.e. pin compatible and machine instruction compatible as well. It is 16-bit processor with an 8-bit data bus. Functionally it is equivalent to he Intel 8086 which had a 16-bit data bus. NEC V30 was pin compatible with Intel 8086. The NEC chips had a better design for integer math operations (link says ~15%). My wife had an IBM PS/2 Model 25 whose 8086 I replaced with a V30. The improvement was not large, but noticeable. [link\|http://lowendpc.com/tech/8086.shtml\|Link.] The Zilog/Mostek Z-80, which I knew quite well, was compatible with the Intel 8080 but had many additional machine instructions. The 8080 and Z-80 chips were used on the S-100 Bus machines of the pre-PC period. I built one of these Z-80 machines almost from scratch. e.g. designed, laid out, and etched copper for the processor board, etc. Anyway, the 8-bit data of 8080/Z-80 vs. (internal) 16-bit data of 8088 (and 8086) difference are such you could not run DOS programs on it. In other words, the programming model of the CPUs are different. [link\|http://vmoc.museophile.com/cards/\|Here's a list of other micros.] Pick one. But if you were PC compatible and not Intel, it was probably a NEC V20/V30.

Post #20,482 by Andrew Grygus 12/6/01 12:19:48 PM Reply	Z80 - 8088 NEC also made a chip, I think it was called the N300 that executed Z80 instructions but was clock and buss compatible with the 8088. This allowed a machine to have both Z80 and 8088 compatible CPUs on the same board. My Octagon 8/16 S100 machine had this and could boot CP/M-80, CP/M-86 Concurrent CP/M-86 and MS-DOS.

Post #20,484 by Silverlock 12/6/01 12:28:15 PM Reply	Damn. I used to have a memory that worked. It was the NEC V20. I think. It also had the 10 Meg hard drive that failed all over the place. I splurged and got a 20 meg to replace it for (IIRC) ~$300. Things are coming back to me. I bought a fancy dancy CGA monitor with a hercules video card to go along with this technical marvel. I replaced and upgraded various parts of the system over the years until nothing of the original was left. I am still using its spiritual succesor.

Post #20,500 by Another Scott 12/6/01 2:24:39 PM Reply	Another machine from the earlier days... In grad school in 1985 or so I got to play with an [link\|http://www.coho.org/~pete/IPC/integral.html\|HP Integral Personal Computer]. It was a "luggable" lunch-box-like portable computer. Moto 68000, 1 MB RAM (512 kB standard), built-in 9" yellow on black (or reverse) EL graphics display. Built-in inkjet printer. Had a new-fangled built-in 700 kB floppy drive (disks were $70 for a box of 10). Ran HP-UX 5 out of ROM. Had a built-in HP-IB interface for attaching to instrumentation, external hard drives, etc. The school was evaluating them as required PCs for the program. The list price was something like $7500 and we were getting them for a little under $5000. It was a nice machine, but too expensive for the students. That's when companies weren't afraid to innovate. :-( Cheers, Scott.

It seemed to run faster at 8Mhz and ran all the same BBS software and MS-DOS utilities that the BBS computer ran before on the 4.77Mhz 8088 chip. As I recall it was just a drop-in replacement for the 8088 that almost doubled your CPU speed.
Post #20,512 by a6l6e6x 12/6/01 3:04:09 PM Reply	Well, you would have had to change the crystal as well. That's the kind of thing IBM made impossible in later machines. The power on diagnostics in the BIOS did a timimg run and would refuse to proceed is the speed was beyond the spec. That was to ensure IBM PC reliability, of course, and had nothing whatsoever to do with the availability of faster machines from IBM.
