EDSAC on your desk.

by allisonp＠world.std.com

< We just to joke that Z80EMU on a Pentium was faster than any Z80 process < you could actually buy, I wonder if it wouldn't be feasible these days t < create a 38 pin I/O port and build an "ICE" in software... < --Chuck thats a tall claim as the z80 is available up to 20mhz and z180s to 33mhz. Then you can also use he Z380 is z80 native mode (it uses fewer clocks per instruction than any other z80) at 20mhz (faster are supposed to exist.). I am in the process of bringing up a Z280 at 12.5mhz (with 16bit zbus) and I expect that with it's instruction cache and fast ram there will be a new level of CPM performance comming. since I have a z80 system that runs at 8mhz (no waits!) and MYZ80 on a 486dx2/66 and the 486 is faster on emulated disk IO (inherent caching) but about the about the same as the 8mhz system otherwise. The disk differences are due to the type of interface SCSI-1 vs SCSI-II and size of buffers. Emulators have their place. One is allowing cross platform code development and testing and the other is allowing access to archetectures that are scarce or unusual. Allison

Motorola UDS modem

by allisonp＠world.std.com

< Apart from the "gee, that really was slow" potential for demonstration, < recreating the past, is there *any* use for old modems? I still use a 2400 Zoom pocket modem with my PX8. The PX8 isn't fast enough to keep up with anything over 9600 and 2400 is generally the slowest most services will go now (some will not go under 9600). Allison

Stains caused by Cigarette smoke

by SUPRDAVE＠aol.com

DONT use purple stuff! its way too strong. i used it once on a pc case, and where it dripped and/or sat on the case, the paint was a lighter shade. its very strong, so if you take appropriate measures, it will clean most anything. the best thing i've found is armor all all-purpose cleaner. safe, and cleans good and wont draw the colour out of anything. it you use lots of it with hot water, it even removes the grease pen price marks from thrift stores. david In a message dated 98-09-22 18:11:28 EDT, you write: > If I recall, the FAQ recommends something called "Purple Stuff". I don't > know > what it is or how well it works or how hard you have to scrub, if at all -- > I've never used it.

Quantum Q540 as a RD52

by CLASSICCMP＠timaxp.trailing-edge.com

>THANK YOU Tim You're welcome! > This is the kind of info I've been searching EVERYWHERE for! And the kind that languishes about in DEC-internal docs :-). Keep in mind that I strongly suspect that at least some of the RD51 numbers in that table are wrong. >The info on the Quantum page was virtually worthless, and I'd not been able >to find anything anywhere else. Unfortunately on the net these days, you're far more likely to find folks trying to act self-important rather than actually dealing with useful technical information. I certainly thought I'd see useful information on 'classiccmp', but it doesn't seem to be any better than the rest of the world. >If you haven't already, could you please >stick this on the PDP-11 FTP site, so the next person will have an easier >time finding it (if it was already there I'm going to feel really stupid).

System 7

by g＠ehrich.com

>1800, used for process control (leading to the S/7). > I worked a lot with the System 7 back in the early 70's and wrote the code on it (TPMM) that controlled the first On-Line ATM in the US. It was at a small bank in central NJ. The ATM (2984 I think) was remote to a System 7. The files were transferred at night to a System 3 by carrying the disk pack across the room. The ATM was called "Tin Teller". The bank was Hunterton County Trust. Never forget the day when testing it the machine at the branch with my young kids along, the looks on their faces when they saw money come out of the slot on the wall. gene@ehrich http://www.voicenet.com/~generic Computer & Video Game Garage Sale

PDP-10 (was Re: EDSAC on your desk.)

by allisonp＠world.std.com

< As far as the -10 is concerned, there would be several hundred (if not < thousands) of modules and the backplane (for want of a better word) was < machine wrapped nest of identical (yellow) wires. I doubt that you coul < reliably follow a signal within a rack, let alone across the whole machi < However, as I said before, I've never attacked a -10 with a scope so I < can't be sure that this isn't possible. Never touched a 10 myself but... I've worked with those who had. Despite it's complexity most of it is the same thing x36 or some sub multiple. So troubleshoorting it would be like attacking and older straight 8 or 8I/L series with it's large number of modules. You follow a problem along a bit path to the point of failure. Usually with a handfull of know good common modules and a scope. Backplane problems were extermely difficult if there were any kind if damage to the wiring or connectors. Allison

Seems the boards were assembled in Mexico and then tested in Texas. Then would fail after a few hours... seems fungus growing on the board from the bad water (recirculated and reused excessively) used would cause high resistance shorts that would affect the microprocessor crystal clock. The fix was a was a wash in good Texas water. Actually, a clean board has a lower fail rate as the cooling is better, no dust or grunge. Case parts can also be cleaned that way if they fit, me I take them out in the driveway and use the hose and a bucket of soapy water. With care you can clean most anything with soap and water... assuming the object itself isn't water soluble. ;) Allison

Mail Mixup (off topic)

by jpl15＠netcom.com

Sorry for this, but it's short. I recently lost correspondence with a list-member... it turned out that my e-mail addr had mysteriously mutated, and mail sent there just vanished, no bounce, no return... zilch. It took a phone call to clear *that* up. [Correct is: jpl15(a)netcom.com] I have written two active list members, with no replies, though they used to do so. So: Seth M. and Paxton... if you are writing me privately... I'm not getting them. And if you've gotten my mail(s) and simply haven't/don't wish to write back.. my profuse apologies to you and the group, and I'll shut up now. Thanks for your indulgence, fellow List-friends. Cheers (digital garlic breath?? nahh....) John

Stains caused by Cigarette smoke

by allisonp＠world.std.com

< Do you have to stop it before it goes through the dry cycle? On mine I can set it for a low energy dry so that varies. I'd suggest letting it start and after five minutes pull it out (warm board will dry faster). < I have a '64 I don't value especially that I'll try this on... anything < else I should know before this venerable machine gets opened up? Anything that can trap water like dip switches or adjustable coils will take a long time to dry. Baking in a 170-180F oven will accelerate drying with little risk. I've done this to PDP-11 and VAX boards, a TRS80 and many other boards that were real grungy. The process used at the factory is very similar to a dishwasher (sometimes is!). Allison

Quantum Q540 as a RD52

If he couldn't figure out the answers to the VS2000 formatter, he's not going to have any easier time with ZRQC! Remember, he's formatting disks that have never been formatted on a VS2000 or RQDX3 before, so he needs all the numbers necessary to MSCP-qualify the disk.

Linux on S/370? Was: Re: printer socket (Off topic)

The S/370s just >do not have the same magic in their name. I can agree with that about their influence. IBM had the marketing horsepower and exposure to put them in many banks, insurance companies, factories, etc. more so than say, Buroughs, CDC and any of the other big names of the day.

He did >not drop too many things. Thanks! I do worry about handling those $750-$1k DeForest Audions that come through. We've done the auction for many, many years as you may know (how long have you been an AWA member?). I've helped for at least 18 years I think. Usually it's myself, Lauren Peckham and his son, David, who are up there every year and several other old stand-bys in the "sold" area to the right. Thank God we usually have light weight equipment compared to classic computers!! However, a few Radiola 60's and the like come through occasionally and they can get real heavy _real_fast_! The three '30's and early 40's console radios and the early TV were auctioned while just setting in place as you saw. I was kinda sick for most of the day from total exhaustion or more likely burn-out while working at the conference. I wasn't my usual wise-cracking self with Lauren and Dave. I had to sit behind the platform for about 15 minutes around 2 PM as I was about to literally drop. That recharged my batteries, so to speak, and was able to perk me up enough to continue helping. We had, IIRC, 620 individual lots with a huge number of vacuum tube lots this year. Quite a few paper lots too. IIRC, $62,400 or so was sold during the 8 hour duration. New record amounts both in lot quantity and money. I got a few rather nice items for my collection including a Crosley 50A Two-step Amplifier with brass-base tipped '01A's for only $150 and a real early version of the Crosley ACE Type V (wooden book condensor, ceramic tube socket, cylindrical tickler coil) for $130. Somebody was sleeping on those rather rare items :-) I like Crosleys since they're quite interesting and SMALL doggone it! It was great to just relax on Saturday AM and listen to the technical talks. If any of us get involved with a computer collecting club or association like the AWA is to Electronic Communications and that club or assoc. begins to have an equipment auction, and I get involved with helping run the auction, please haul me away to get my head examined! I'm staying HOME!!! :-) Imagine lugging around Cromemco, CompuPro or other loaded S100 systems, or DEC RL02 drives, or IBM DASD units during an auction. Those are truly comparative boatanchors like an RAL-7 or R-390 (old military radios for the unwashed out there) but we sure love 'em, don't we! ;) I did not see you. Should have come up to me and introduced yourself. > >William Donzelli >william(a)ans.net > Christian Fandt, Electronic/Electrical Historian Jamestown, NY USA Member of Antique Wireless Association URL: http://www.ggw.org/freenet/a/awa/

Transformer

Transformer

by maxeskin＠hotmail.com

I visited Radio Shack yesterday, and look for a step-up transformer for my European C-128D. They had everything neatly labelled, but how do I find out how many watts it's rated for? It has a measurement called 'V/A Cap' which goes from about 70 to over a thousand. The prices goes up with it. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Vectrex (RE: For Sale/Trade at the VCF - plus want list)

Whoops, yeah, 6809, typo. I actually have another one that I'm keeping, equipped with Sean Kelly's terrific Multicart, a cartridge that has all of the Vectrex titles ever created with an on-screen menu select (http://www.xnet.com/~skelly/). A guy named John Dondzilla is programming NEW games for the Vectrex (http://www.monmouth.com/~pcjohn/) This is only slightly off-topic, since there was actually a plan to market a Vectrex keyboard add-on that would make it a full computer.

Removing mailing label gunk

by jon＠techniche.com

Hi Manney, I frequently buy books that are discounted or second hand. These always have annoying old labels on them that are a pain to remove. And my goal is to save the books cover at the same time (typically these are the glossy style covers that are popular for computer books these days). What I do is remove the majority of the "gunk" either with my fingernail or carefully with a pocket knife and then I use something with a sticky backing to remove the rest. The material with a sticky backing might be the label I just removed or scotch tape or a new label I've peeled off of some junk mail. You take that stickey material and repeatedly (like 50-60 times), stick it on the gunk and then peel it off again. This is incredibly tedious, but it works like a charm. You end up with a perfectly clean surface with no damage done during the cleaning. This may not work for you epson since you may not be able to reach all the places where there is gunk. But give it a try. Jon >An Epson gas eaten several mailing labels over the years (I think at least >_some_ of the labels must be 10 years old!). > >What's good stuff to remove the gunk without melting the plastic? > >Thanks, >manney > >

The VS2000 low-level format will be compatible with the RQDX3. (The VS2000 format isn't compatible with the RQDX1/2, though.) Megan suggested: >Then what you want is the XXDP+ kit, and the ZRQC formatter. The ZRQC?? formatter will do the trick, too, but the VS2000 formatter is far more convenient and robust. I keep a VS2000 around for no other purpose than formatting MFM disks when I have to.

Strange Q-Bus Board, SCSI?

by healyzh＠ix.netcom.com

I got a bunch of Q-Bus and Unibus boards today, most of which are DEC, and most of which I was able to identify. One really caught my eye that I can't identify however. It's a Quad-Height board with a 50-pin connector on it There is one chip with a Model number on it "UTS25". The board looks to be manufactured by either MTI or MT, not sure which. The one EPROM says "MTI-U/B A3.4". It has a Z80B CPU from SGS, and a Zilog Z0853606PSC chip. However the chip that really caught my eye was a WD33C93-PL. Could this be a fabled SCSI controller? The WD chip is the same as an Amiga 3000's SCSI controller. Zane | Zane H.

Shoe collectors?

by WHoagIII＠aol.com

There is a Shoe phone out there in the marketplace, I have seen one. The shoe phone is over 10 years old so It is not too far off topic. The population of collectors is growing by leaps and bounds. The internet revolution is making it much easier to get together and form community. I too am amazed at what collectors collect. Paxton

Quantum Q540 as a RD52

by CLASSICCMP＠timaxp.trailing-edge.com

>Not a silly question in the least. Sort of falls in the "now why didn't I >think of that" catagory! In all cases except 1 DS1 was jumpered, on the >one exception, nothing is jumpered. Set it to DS2, no luck, set it to DS3 >and it works. Thanks! This falls into the category of "my 11/73's line time clock quit working" :-). *Extremely* common problem, extremely simple answer! >Next question, does anyone happen to have the list of correct answers to >give the formating program written down anywhere? Yes, I'm lazy enough not >to want to have to figure that out. Roger Ivie posted the following many, many years ago. It's for the RD51, not the RD52, but it should get you started. One tiny note: Roger didn't figure out the Media ID scheme, but if you look at the source code to my DUSTAT utility (i.e. take a look at: http://sunsite.unc.edu/pub/academic/computer-science/history/pdp-11/rt/dust… ) and look at my comments there about how the media type code is represented. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology Voice: 301-767-5917 7328 Bradley Blvd Fax: 301-767-5927 Bethesda, MD, USA 20817 I've come across the notes I used to format an RD51 (that's a 10MB disk, folks) on a VS2000. When I was done, I was able to mount the disk under VMS. Here's what my notes say: An XBN is a block containing geometry info for the drive. DBNs are the blocks between the XBN and the end of the cylinder; essentially, the first cylinder of the drive is reserved to contain geometry info, but not all of the blocks in the cylinder may be used. DBNs fill out the first cylinder after all the XBNs are filled in. LBNs are blocks containing user data. RBNs are replacement blocks. RCTSIZ appears to be the size of the replacement block table in blocks, but I have a ? after my note on that one. RCTNBR appears to be the number of copies of the RCT on the disk, again I've makred that with a ?. Here were my answers to the questions for the RD51. The RD51 has 305 cylinders and 4 heads. I'm pretty certain the VS2000 and RQDX3 use 17 sectors/track (the RQDX2 used 18 sectors/track; reformatting a disk with an RQDX3 drops its capacity slightly): XBNSIZ: 54 I used 54 because all the info I've seen for other drives used 54. DBNSIZ: 14 A cylinder on the RD51 has 68 blocks. After the 54 XBN blocks are allocated, 14 blocks are left in the cylinder. LBNSIZ: 20000 I just winged this one. You should be able to twiddle this up or down by playing with the replacement blocks. RBNSIZ: 168 I think I picked this because that's what an RD52 uses, but I don't remember. SURPUN: 4 The RD51 has four heads. CYLPUN: 305 The RD51 has 305 cylinders. WRTPRC: 305 I don't remember where write precomp is supposed to be turned on for the RD51, so I turned it off for the whole drive. This should be the cylinder number where write precomp starts. RCTSIZ: 4 Again, taken from the RD52 RCTNBR: 8 Again, taken from the RD52 SECITL: 1 Sectors should be number 1 through 17 instead of 0 through 16. STSSKW: 2 Head-to-head skew in sectors. The RD52 also uses 2. CTCSKW: 14 Cylinder-to-cylinder skew in sectors. I don't remember why I picked 14; some experimentation should let you figure out what to use here. MEDIAI: 627327027 I'm pretty sure I looked in the source listings to see what the driver was expecting for an RD51. Short of doing that, I don't know what else to do here. I don't know if this number is really critical for antyhing; the driver should use the XBNs to get the geometry information instead of depending on the media ID to look it up.

Shoe collectors?

by dastar＠ncal.verio.com

You people thought you were weird. Would you believe there's an article in the Wall Street Journal today about people who collect (and pay outrageous eBay sums for)--get this---old sneakers? A pair of some Nike something-or-others sold for $2,300 on ebay, and some fetch up to $5,000. And we thought all the money was in Altairs. I'm sorry, but sneakers I can not understand. Computers, yes. Beanie babies, maybe. Sneakers?? Sam Alternate e-mail: dastar(a)siconic.com ------------------------------------------------------------------------------- Ever onward.

Tandy 600 questions

by tomowad＠earthlink.net

I purchased a Tandy 600 at the York Hamfest on Sunday. The unit doesn't seem to work - the screen fills up with garbage (just alternating pixels, about 75% black). Anybody know what could cause this? I'm trying to take the unit apart so I can look at it, but its not opening up very easily. Are there screws under the four rubber feet on the bottom? They're in so good I'd have to tear them apart to get them out, which I hate to do unless I know there are actually screws under it. Thanks.

Tandy 600 questions

by roblwill＠usaor.net

Don't take apart. The only time you should have to do this is when you need to replace the battery pack. Here's what you should do: Perform a cold start. Before you perform a cold start, be sure the RAM Memory switch on the bottom of the computer is ON. Then, briefly press the [BKSP], [ALT], [LABEL], and [POWER] keys at the same time. Release the [POWER] key first, then the others. All data files stored in memory are erased, and the System Manager screen appears. If this doesn't work, turn off the RAM switch, and try everything again after a minute. Just remember to turn the RAM switch back on before you do.

Quantum Q540 as a RD52

by CLASSICCMP＠timaxp.trailing-edge.com

>VSfmt_RES_ERR #2 > 84 FAIL > >It does this for each of the drives. The drives "sound good" for what it's >worth. Is there some special trick to getting a Q540 to act like a RD52 Really silly question: what have you set the drive select jumper to on the Q540's? Generally on VAXen you have to set the DS to the third position (DS3 if it starts at one, DS2 if it starts at zero.) -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology Voice: 301-767-5917 7328 Bradley Blvd Fax: 301-767-5927 Bethesda, MD, USA 20817

Linux on S/370? Was: Re: printer socket (Off topic)

by Marty＠itgonline.com

How many DeForest double wing audions did Chris drop? Did they bounce or shatter? Marty ______________________________ Reply Separator _________________________________ Subject: Re: Linux on S/370? Was: Re: printer socket (Off topic) Author: classiccmp(a)u.washington.edu at internet Date: 9/21/98 11:16 AM > Less S/370s out there? I would think, since they are more recent vintage, > there would be more. Any reason why? I'll keep my eyes peeled for you though. I think is simply the prestige of the S/360s. After all, they are probably the single most influential computer family of the 1960s. The S/370s just do not have the same magic in their name. > Yeah, even my beige box 9370 is boring as heck to look at :-( (It's a CMOS > version of the S/370 from 1987/88.) No interesting front panels, can't > tinker with hardware much at all, etc. Pah! Even the last of the machines tagged "System/370" started to lose their panels. By the time the 3033 and 4331 came out (mid to late 1970s), the panels were gone. IBM used the same cabinets until recently switching over to the black and red (very sharp looking) S/390s. S/370 panels are amazing. Unlike the S/360 panels, they are black with all sorts of color coding, and liberal use of the hexadecimal knobs for setting the registers. I would like to find a picture of any old S/370 on the Web, but I have not come accross one yet. > Christian Fandt, Electronic/Electrical Historian Lets give Chris a big hand for being an Auction helper at the Antique Wireless Association meet in Rochester, NY just a few weeks ago.
