Speaking of PS/2s...

What did you ask "Santa" for this year.... : )

My wife and I just picked up a VAX 4000-500 for my Christmas gift.

Selling ESDI drives (was Re: Speaking of PS/2s...)

Russ, if "tons" >= 100 try the purchasing dept. at hitechcafe.com. They sell a lot of older drives including ESDI, and would probably be interested in the lot.

Found today ISD EPROM?

by jrkeys＠concentric.net

Today I stopped at a thrift and found a Blue/White metal device made by ISD and can't really figure it out. It has a place burn a chip and the one in it is ISD 1016 AP; a four inch speaker at the top and on the front side panel it has hook ups for a headset, in and audio, power supply. and RJ11 jack. On the circuit board I found this writing "ES001D Evaluction Unit 1995". There is no writing on the metal case or decals what so ever. Any one seen this unit before.

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

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.

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
