PPro (was: RE: Need manual URL/hardcopy for HP Netserver LX Pro 6/200 serve)

by ken＠seefried.com

From: "wizard" > PS: Still not conviced that PPro is "worthy" CPUs. I view it as > "bastard child" of PII, celeron is even worse. Excuse me? Considering the PPro is significantly older than the PII, it would be hard for it to be the child. Further...the PPro has faster cache (clock == core, as opposed to clock == 1/2 core on PII) and on some versions more cache than the PII (up to 1MB). Clock for clock, the PPro is a better chip than the PII, it simply never got clocked up as high as the PII (for a number of mostly economic reasons).

Security bits

by paul＠wccnet.org

I purchased a 33 piece security bit set from Radio Shack for $8 last May. They had to order it and it cost me $2.50 more for delivery. I just checked www.radioshack.com and I found it for $13 in the tools section (catalog number 910-5247). The URL is http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&category%5Fname=C… Paul R. Santa-Maria Monroe, Michigan USA

Toshiba T250 & moving files

by djg＠drs-esg.com

I got this and can't really help. From what I understand if you assist him so he can get the files off then he is willing to give the machine. Sorry, didn't think until now to ask where he lives. Reply to address in message below. -------- Original Message ----------- From: "Dave Bradshaw" <dave(a)fishmonger.com> I own a Toshiba T250 CPM PC that is around 17 years old. It is in excellent condition, and fully operational. It has 2 8 inch floppy diskette drives. The disk drives are high capacity, and the floppies contain 1MB of data. I have a lot of text data that I would like to move to a Windows based system. I'm looking either for an 8 inch drive that I can connect to a Windows PC, or another solution. I have never been able to locate a communications application that will wild card the file transfers, making the job way to ponderous to do one file at a time. There are literally thousands of small files. Do you know of an 8 inch drive that is compatible with a Windows PC and my high capacity 8 inch floppies. Also, if you are interested in my machine I am more than willing to part with it after I move all the data. -------- Original Message ----------- I pointed him to http://www.cpmspectre.pwp.blueyonder.co.uk/cpm/cpm_faq.htm#q14 http://www.cpmspectre.pwp.blueyonder.co.uk/ and classiccmp.

Initially all 2048 bits of the PROM are in the '0' state (outpiut low). Information is introduced by selectively programming '1's (output high) in the proper bit locations. All 8 address bits must be in the binary complement state when pulsed Vdd and Vgg move to their negative levels. The addresses must be held in their binary complement state for a minimum of 25 microsec after Vdd and Vgg have moved to their negative levels. The addresses must then make the transition to their true state a minimum of 10 microsec before the program pulse is applied. The addresses shouyld be programmed in the sequence 0 through 255 for a minimum of 32 times. The eight output terminals are used as data inputs to determine the information pattern in the eight bits of each word. A low data level (-48V) will program a '1' and a high data input (0V) will program a '0'. All eight bits of one word are programmed simultaneously by setting the desired bit information patterns on the data input terminals. During the programming, Vgg, Vdd, and the Program Puilse are pulsed signals. See page 2 of the data sheet for required pin connections during programming.

Info needed on 1702A programmer

by r_beaudry＠hotmail.com

Hello all, I recently obtained a 1702A EPROM programmer, but it's having some problems. Does anyone have docs or schematics for the following programmer? Tenor Inc, Model 763 Solid State Programmer Other markings: EPROM Loader 763-7-0120, S/N 763 3303 P 1083 See http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1678511077 for pictures. It helps to see the item for the description below... Basically there are 16 switches/LEDs. In Read mode, the LEDs should show the byte values, and in Write mode, the switches select the data, and the LEDs should reflect the data being input. None of the LEDs fire. There is a display for memory location, and it properly resets when "reset" is pressed, and properly increments when "step" is pressed. One other note, the "load" button is supposed to write the data, and advance the memory location display, but the memory location does not advance... I suspect at least the "Read/Write" switch is bad, as it is very mushy feeling, and doesn't seem like it is switching. Perhaps that holds things in some weird state. Standard DPDT, so no big deal to replace. Beyond that, though, I'm at a bit of a loss w/out docs or schematics... Disassembly reveals no blown parts, no smoke marks/burns, and no broken connections.... Thanks!

5.25in. Floppies

by doc＠mdrconsult.com

Is it just me, or is there something not-so-subtly ironic and gratifying about a 450mHz desktop with a working 5.25 floppy drive installed? Not to mention the fact that I "just happened to have" enough new DS/HD floppies (~60) for this entire floopy-based (sic) install? And, am I the only one who forgets just what a PITA it is to handle lots of them? Doc

Going to the dump...

by wh.sudbrink＠verizon.net

Located in Silver Spring, Maryland. Pick-up only, unless you can really convince me to ship (read $$$). Going to the dump tomorrow afternoon (1/23) unless spoken for: 1) TeleVideo Tele-XT. Flakey power supply. Physically OK... all parts present. No software or docs. 2) Heathkit Model IO-4550, 10MHz, Dual-Trace oscilloscope. Physically good, electronically unknown condition. No probes, some docs. 3) Hickok Teaching Systems Model OSK-4 D.C. Wide-Band oscilloscope. This guy is tube (valve) based! Physically OK (a little rust and dirt, missing "DC Bal." knob), electronically unknown condition. Some probes, no docs. 4) A mangy crate, with handle and casters, designed to hold a Teletype Model 33 KSR. Maybe made by Teletype but no markings to that effect. Didn't protect its last occupant very well. 5) A Compaq DeskPro 286e in original box. Good physical shape, unknown operational condition. You may end up with other stuff if you drop by, being unemployed is forcing me to clean up my basement. Please contact me before stopping by.

MCA memory card

by aw288＠osfn.org

I recently pulled a Expanded Memory Adaptor/A card out of a PS/2 model 60 (part number 61X6752). I do not know much about this thing - I have never seen one before. This is not a great suprise - I am not really a PS/2 kind of guy, even though I ought to be. I need to sell this for RCS (we need money), and would like to know *anything* about it, like if it is even worth throwing into the 'bay. William Donzelli aw288(a)osfn.org

The scsi card sees the tape drive and windows finds new hardware but has no driver. I have googled all over and can't seem to find a windows driver for this at all. :^( can anyone help? grovel grover for off topic post.

Probably more like rdT0 or rhdT0 (where T is a type of drive... or not there at all), or rd0s0d0. The "r" is likely to be important because many unixes require a "character" type device to actually make a filesytem on a disk, and in fact to do many disk-level operations. The "r" device prefix generally denotes this. For instance, on RISC/OS, SVR3.5, and I believe SunOS 4, you'll see just that. I've always imagined the "r" to stand for "raw" or something similar, but I'm not sure. > > Also note that early version of AIX were much more like > "something strange" > than they were like normal Unix.

Bell & Howell Apple IIe

by Innfogra＠aol.com

IIRC all of the black apples I saw were IIs and II+s. I think a black IIe would be rare. The audio box on the back was used in a classroom setting to hook each operator to the teacher in an audio network. B&H was a big vendor into the A/V and classroom solution market. Paxton Astoria, OR

Documation M600L - HP 2893A Card Reader

by brian＠quarterbyte.com

I just picked up an HP 2893A punched card reader on eBay -- it appears to be an HP-badged Documation M600L. I haven't been able to find any documentation for it on the web. Does anyone have any info on this or similar card readers? Is it similar to any of the DEC-badged CR11 readers? Any help, especially interfacing info, will be appreciated, thanks, Brian

ISTR No VMS distro was available on floppy, the only VMS floppies I can remember were boot disks for MicroVMS round V4.x. Also, all 3100s have SCSI as standard, the only differences were the type of SCSI connector that was presented externally. Older machines had the female HD68 connector...... CDs were available for 5.4-2 and above I believe; I'm pretty sure I've got most versions from then upwards. a

HP 9000 800/G40 serial cable

by csmith＠amdocs.com

Hi everybody, I've got a new project. An HP 9000/G40, which may not be (probably is not) 10 years old, but there's little information available on HP's site (that I can find), or any other, and I rescued it from a scrap yard, which may make it on topic anyway. I wonder if anyone can tell me how to get the cable that plugs into the mini-DIN looking port so that I can see the boot messages and talk to it? Also, where can I get information on this machine? (Max memory, number of CPUs, etc...) Thanks, Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

Need manual URL/hardcopy for HP Netserver LX Pro 6/200 serve

The PPro is easily the best x86-architecture processor those bozos at Intel have ever released. The PII is a total piece of crap in comparison, in my opinion. If anything, it's the PII that's the bastard child of the PPro! I'm not trying to be argumentative here...and I'm CERTAINLY not defending any of Intel's crappy designs...but I believe the PPro is indeed the best of the bunch, and as such, I suggest that it might be worth another look. -Dave -- Dave McGuire St. Petersburg, FL "Less talk.

Heheh, OK, so VMS on floppies isn't realistic - I've obviously been spoiled by my time with a Sun 386i :-) I guess I'll get a CD drive, join DECUS and get myself the 7.2 CD. Thanks for your help and advice, everyone :) Cheers Al
