6502/Z80 speed comparison (was MITS 2SIO serial chip?)

by ajp166＠bellatlantic.net

From: Richard Erlacher <edick(a)idcomm.com> >without modification, in most cases, on a Z80,.by the time the 6502 became >popular. Now, I've always believed the 6502 at 1 MHz to compare favorably with >the 4 MHz Z80, but I used the Z80 running CP/M 2.2 to do useful work, since it >was a lot more trouble squeezing useful work out of a 6502 back in '78-'79. If anything I'd say CP/M was a factor more than any virtue of Z80. I say that as most "z80" code underused the Z80 as a fancy 8080. One may wonder if a cp/m like (or better!) OS existed for 6502 such that it was portable or easily ported if things may have developed differently. Allison

D*A*T*A* I*/*O* M*a*n*u*a*l*s

by mranalog＠attbi.com

Last fall I suddenly, in the space of two week, received five requests for a D*A*T*A* I*/*O manual I mentioned on ClassicCmp back in 1999. Thank to help from Arlen Michaels, I got all of those requests filled. Now, I don't mind copying manuals, but after two years and one move the manual and the files where a pain to dig out of "the pile", and these were not list members. So, the ClassicCmp list archive is the reason for the "*"s. Now, one of the people that requested a manual sent me a couple of PDFs that I wondered if anyone here would like to host? I want to get them out there so everyone can use them, but I didn't want to keep getting requests years from now via the archives. 1. D*A*T*A* I*/*O* 2*9*a* U*n*i*v*e*r*s*a*l* P*r*o*g*r*a*m*m*e*r* 9*9*9*-*0*0*2*9* dated May 1982 102 pages (includes schematics) size - 10 MB 2. D*A*T*A* I*/*O* U*N*I*P*A*K* 2* dated 1984 76 pages (includes family, pin*out codes and schematics) size - 8 MB So, if ONE person would like to host these files, (and not mention my name) I can put them up on the web one at a time to be grabbed.

Pyramid 90x

by dancohoe＠oxford.net

I recently brought home a Pyramid 90x. The old owner who had run the machine at his work in the 80's bought it from his employer about 1990, but never got it set up at home. Apparently he decided to dump it a few months ago, but because of its size didn't get the job done. However, he did put all of the software and the documentation on the curb for the garbagemen at that time. Mike Kenzie and I got there just before he called the recyclers for the machine itself. What I need is a boot disk or other software and any documentation that might be out there. According to the old owner, it starts by loading the boot program off the 8" floppy before it can find the fixed disks. Does anyone have anything for this machine? thanks, Dan Cohoe

6502/Z80 speed comparison (was MITS 2SIO serial chip?)

by CLeyson＠aol.com

Come on guys cool it. Who really cares if a Z80 is faster than a 6502 ? I sure as hell don't. For those who are interested check out the following: US Patent 4004281 Microprocessor Chip Register Bus Structure (6800) US Patent 4332008 Microprocessor Aparatus and Method (Z80) US Patent 3991307 ...on the fly correction to provide decimal results (6502) By the way, the 6800 Patent has complete circuit diagram. The Z80 also contained DRAM refresh circuitry that the 6502 didn't.

Round two: PC vs the Dishwasher

by rschaefe＠gcfn.org

Well, it turns out the case isn't in as good of shape as the boards inside it. After a good washing, the cover has surface rust all over it. Not from the washing, but from the 'storage' it sufferred thru before I came across it. I ended up taking out the top drawer to make enough room to stand the case on it's end. I tried with it sitting flat on the top of it, but that didn't work out so well-- hadda run it thru twice. Bob

ROM preservation

by csmith＠amdocs.com

I've been thinking recently that I should possibly get a ROM reader/writer so that I can preserve the ROMs out of all my old parts, and I was wondering whether anyone had some experiences (good or bad) with any different programmers? Which programmers are good, which aren't so good, and why? Where is the best place to get one, and which is the best to get on a tight budget? What about making your own? (Note that I think this may be an interesting project, but I'd really rather put my time into other things right now, so this is near the bottom on my list of options...) One called "Leaper 3" interests me because of its ability to copy one ROM to another without any kind of computer hookup, which I imagine might be useful, but I know nothing else about it.

Tinning on old PCBs

by ajp166＠bellatlantic.net

Are you sure it was the solder plating and not the resist(solder) mask(a plastic like over coating material)? If it was the tinning, that's there to improve solderability and appearance as well. The tinning adds very little to the current carrying capability as tin and lead have significantly more resistance than copper.

Round One: PC vs The Dish^H^HBoardwasher

by rschaefe＠gcfn.org

Well, the motherboard, mono card, floppy card, & JRAM just came out of the dishwasher. Sparkling clean (no soap or rinse agents!) and hanging up to dry in the basement for a while. The relay for the cassette has a little condensation inside it, but I'm not too concerned-- worse case I'll pop the plastic cap off. I used hot water, as this thing was filthy. The case is in now, and the cover to follow after that. I think I might use a little soap on the cover-- it's that bad. I left out the AMD harddrive controller and Hayes modem, due to paper ROM stickers & a real honest-to-god paper coned speaker respectively. I won't be able to try it out until I find a clock generator for it, but I figure I have a week or so to do that in anyway. Bob

Power Series

by csmith＠amdocs.com

Well, speak of the devil... and all that. After mentioning yesterday that a Power Series machine would be nice to have, I found that somebody brought one home for me. (seriously...) So before I get started here, let me also mention that it would be nice to have: A Symbolics Lisp Machine A Next Dimension Cube A PDP-11 in a small rack with blinkenlights and core ... enough of that, though. :) So, I now am the proud owner of a Power Series VGX machine. It seems to have 4 40Mhz CPUs in it, a full compliment of graphics boards, FDDI, and some extra video I/O boards. It's a deskside type machine, the whole thing fitting in one very large tower --err... coffee-table :) Firstly, this machine is in need of: The plastic "skirt" piece for the right side of the chassis. The plastic back plate. The power-cable. Keyboard, monitor, mouse (all of which I can probably get locally... (that's it.. I think I have the entire machine otherwise) Does anyone know where I can get these, or (in the case of the power-cord, for instance) parts to make them? Any warnings/information/antic dotes for these machines? I do intend to use the thing. I also intend to use it at home. It appears to require 20 Amp service, though, and I have no good 20 Amp outlet within reach. I do have some 20 Amp and a couple 30 Amp fuses (Yes, fuses. I intend to replace the one I hook this to with a mini-breaker) in the box, which I intend to trace before I decide where to plug it in. It may be that I'll contract somebody to run a 20 Amp outlet for this machine. (Never having done AC wiring work on my own, I feel that I don't want to start by wiring an outlet for this beast) Otherwise, the plan will be to plug it into a circuit with a highly rated fuse on it, and unplug everything else. Any holes in this plan? The breaker on the power-supply is rated 16 Amps, btw. I have no idea how much pull to expect from a monitor -- anyone know whether I can safely use both on the same circuit? That would simplify things. I believe a best option is to have somebody run a line up from the washer/dryer hookups in the basement. Those are hooked to 30-amp fuses already and have cutoff switches. As long as nobody does laundry while the machine's running, then, it would be fine. :) Lastly, even before I get this thing plugged in, I'd like to inventory it, and check it for health. What should I look for? Regards, Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

Now I'm impressed.

by doc＠mdrconsult.com

Hey, all. I posted some questions about VMS a couple of weeks ago, got some good answers, mostly "where to start" and have been scratching up for a copy to go on my VS3100. I have Alpha OpenVMS, but it seems more "fitting" on the little VAX. A couple of weeks ago I picked up an SZ12 drive enclosure with a pair of RZ56 drives in it for $22 incl. shipping. I just powered it up, tried booting the vaxstation off the first disk, and I'm looking at the login prompt on a v5.2 VAX/VMS system. OK, now I'm looking at the command prompt. The SYSTEM password was "system". TeeHee. The guy I bought this from says he has its twin. I'm mailing a money order tomorrow. Happy Solstice, Doc

8284a, where to find?

by rschaefe＠gcfn.org

I don't think I'm going to be able to repair the clock generator from my IBM PC (twisted off gnd & rst in a fit of stupidity), but I don't know where to look for another one-- mouser and digikey are all that comes to mind. (Is this an 8284a, or an 8284?) Also, the wife's going to work tomorrow, I'll run the boards thru the dishwasher and tell ya what happens! ja ne Bob

MITS 2SIO serial chip?

by ajp166＠bellatlantic.net

>Ben Franchuk <bfranchuk(a)jetnet.ab.ca>: > >> what is the faster CPU -- A 6502 or Z80 style processor like >> the rabbit. Depends... For the same instruction execution rate (ignores clocks and cycles) the z80 is likely faster. However... if you have a 20mhz 6502 and a 10mhz z80 it gets muddier with the 6502 being the faster. And if you know one better than the other you can certainly exploit it all the more. In the end it's not which one does a task faster, it's what one you can code the task for faster. Sorta like asking apples or oranges. Allison

MITS 2SIO serial chip?

by ajp166＠bellatlantic.net

From: Ben Franchuk <bfranchuk(a)jetnet.ab.ca> >I suspect this is because > >1) All registers but the PC are 8 bit. Total number of bits including storage for status were about 1/3 that of Z80 (208). >2) Instructions grouped into fewer internal states per clock. Yes, and instructions were simpler in construction. Some Z80 instructions like the block moves and searches (ex LDIR) and a complete set of IO instuctions (not present on 6502) made for a great difference in size and complexity of the instruction set. > I think a z80 instruction could have 17+ states where a >6502 used up to 5 states. Actually Z80 went as far as 22states. Allison

Thanks Jeff, it's a while since I read the Wireless World article on the "Chase me Charlie" bomb and I think your're right about the sinking of an Italian battleship. I know it's off topic, but it's quite a feat of engineering stuffing tubes (valves) into shells or bombs. I'm still curious as to how the RF proximity fuses worked. Missile guidance computers are probably a valid topic for discussion on classiccmp. Anybody read Jack Volders paper on the Cordic algorithm ? A true classic. BTW would a "classic algorithm" thread be a valid topic for classiccmp ? It would make a good read and it would be educational too. Chris
