Does anyone have RM03 prints?

by dseagrav＠sakura.lunar-tokyo.net

I'm rebuilding an RM03 head stack (I have two crashed drives, making one good one from the two), and I got a problem here... Drive one has all of the heads bad except for platter 2, head 1, and surface 3, head two. (That is, I have one good UP head, and one good DOWN head.) Drive two has all of the heads good, except for the heads for platter 1. That is, I have both the UP and DOWN heads for the topmost platter dead. The problem is, the good UP head from the first drive is the servo head, apparently - The pigtails for this head come out on the opposite side from the others, and it has a double-ended connection. Can this head be used as a normal data head anyway? The pinout looks the same, except that it has two endings, both of which look alike... Can someone look at the RM03 prints and find this out for me? This is my only good UP head, so if I roach it, I'm done for. PS: Ripping the drive apart and getting the head stack out to play with was somewhat easier than it looked like; All I had to do was get the big magnet out of the back, have someone hold the logic cage while I undid the drive head pigtails, undo the track 0 microswitch, disconnect the big coil at the end of the head assembly, and pull the whole mess out the back of the drive. Oh, and I'll have to take pictures of the crashed heads later; They're really impressive! The original top head for the second drive is COMPLETELY GONE. I have both the head and the platter it crashed onto stored upstairs to take pictures of as soon as the camera works again.

A good book was written about this back in the late 80s by the bloke who taught us about digital design. I forget the title, but the author is Peter Thewlis and the book was published by the Oxford University Press. Takes you all the way from the basics of how to build various flip-flops to how to build registers and an ALU. Excellent fun :) --al

Does anyone know how to take the rolling feet off a BA215?

I accidentally deleted the message before I read it completely, so I don't know what you said after commenting about the VUPs rating for the 7650, but the 7650 is about 155 VUPs, not 175, according the table I got from DEC. The 7610 is 35 VUPs, and each processor adds 30VUPs. You lose the rest due to overhead. -- Eric Dittman dittman(a)dittman.net Check out the DEC Ethusiasts Club at http://www.dittman.net/

I don't think an 11/34 or similar would come anywhere close to a 486DX2-66 in terms of processor speed. More like a slow 286. The real advantage of a mini was the architecture, which was designed to reap the benefit of multiple intelligent DMA subsystems and perhaps multiple busses. The same is true now, comparing expensive SGI kit with fast Pentiums -- you only see the advantage on specific tasks, like certain kinds of rendering. > Any suggestions for a fair race?

I was wondering about this! In all honesty I don't see any reason to go this low level, by doing this you're making it less portable. Ideally you want something like a stripped Linux or QNX system sitting on top of the hardware, with the system emulator sitting on top of that. If you want to avoid UNIX altogether, just take simh, and set it up so that it's started when the system boots, and you boot all the way up to the OS of your choice. Go one step further and hack simh so that if you shutdown the OS running on top of simh, that it shuts down the host OS. If you want to do hardware, go with FPGA's and reimplement the CPU and controllers like Neil Franklin is trying to do with the PDP-10. The tricky part here of course being the disk and tape controllers (unless you want to write your own device drivers). Zane

The last one I soldered was a DIL chip. Timing might be a problem; I have almost no idea what access time DIMMs are supposed to be but I expect it's faster than SIMMs. SIMMs are usually in the 60ns-120ns range, and it's not too hard to get FLASH or EPROM in that range too.

Worm/Virus alert

Hey all, Sorry bout the spam (and sorry if you already know about this) but I figured you folks might want to know to watch out for a new Code Red-esque worm that's running rampant...below is from SlashDot. http://slashdot.org/articles/01/09/18/151203.shtml -- MB ************** New (More) Annoying Microsoft Worm Hits Net Posted by CmdrTaco on Tuesday September 18, @10:10AM >from the what-a-pain-in-the-arse dept. A new worm seems to be running rampant Unlike Code Red, it attempts to hit boxes with many different exploits (including what looks like an attempt to exploit boxes still rooted by Code Red). It looks like each IP tries 16 attempts on its neighbors. There is also a new mail worm mailing WAV files or something with bits of what appears to be the registry... it may or may not be related. Got any words on this? Shut down those windows boxes and stop opening attachments. And make that 21. Got another one while writing this story. All my hits are coming from 208.n.n.n (where I am) I'm sure it'll keep moving to nearby boxes. Here are examples of the requests it's sending: GET /scripts/..%%35%63../winnt/system32/cmd.exe?/c+dir GET /msadc/..%255c../..%255c../..%255c/..%c1%1c../..%c1%1c../ ..%c1%1c../winnt/system32/cmd.exe?/c+dir GET /_vti_bin/..%255c../..%255c../..%255c../winnt/system32/cmd.exe?/c+dir While writing this story I was hit a total of 4 times, 16 GET attempts per attack. In only 4 minutes. Also of interest, My desktop has now been hit about 500 times today, all from 208.x.x.x IPs. This might be really bad. I still haven't read anything about this anywhere else, so you heard it here first ;) Update: Web servers compromised by this worm apparently attach a "readme.eml" to all web pages served... and due to a bug in IE5, it will automatically execute the file!

So I finally had time to pick up my MMJ crimper....

by fernande＠internet1.net

It came in last week, I ordered it from Kendall electric. It's an Ideal Industries Crimpmaster. I was a little disappointed to find that it was made in Taiwan. Oh well, at least they are allies. I bought the connectors to go along with it too. I got home, promptly cut off the filed down standard RJ11 connector off of one end of my cable. THEN, I tried putting a new connector into the crimper.... I couldn't figure out how the dumb thing was supposed to work! I was thinking GREAT, I just dumped 70 bucks into a specialized tool I can't seem to use. I checked part numbers several times. Turns out the MMJ die set was in wrong.... they misassembled it at the factory. It worked fine once I straightened it out :-) Now I have a proper cable :-) Maybe sometime soon I can start messing around with the Vax again.... still need to break into VMS.

Embedded PDP-11 Processors

by dittman＠dittman.net

DEC used embedded PDP-11 processors in many different places. There's the console for some of the VAX systems, and I've read some of the DECsystem-10 or DECSYSTEM-20 systems used a PDP-11 as a console system. Other uses of the PDP-11 that I know of are the HSCxx controllers and some of the printers. Where else did the PDP-11 get embedded? I know the HSZxx/HSDxx/HSJxx controllers used an Intel i960 processor, so there's no PDP-11 there. And speaking of the HSCxx controllers, are the PDP-11 controllers customized or is there a standard QBUS or UNIBUS system in there? -- Eric Dittman dittman(a)dittman.net Check out the DEC Ethusiasts Club at http://www.dittman.net/

The console keyboard (basically a 029 keyboard) was mapped into three shift states (3 symbols per keycap) with the shift state being indicated by banks of front panel lights. IIRC, make sure to make lots of copies of the APLIPL card as my experience was that the reader/punch would occasionally munch it. Also IIRC, the correct name for the IPL card is a "Cold Start" card. > We also have the maintenance manuals and schematics, but > no diagnostic software listings.

To garbage or ask for it: Commodore printer MPS801, TIs, Commodore 1525, DEC LA50, TRS80 Mod II exp box etc...

by claudew＠videotron.ca

Hi Garbage day tommorow and I will be scrapping more stuff I have accumulated too much of... This all going to charity (they probably wont want this) or garbage in about 24 hours or pick it up if you want it. I dont wanna start packing -- you have to have someone to pick this up. I know this is quite a long shot since I am in Montreal, Canada but who knows... A shame because most was cleaned and is working....most of this is stuff I have more than one of or just no space for... I anticipate more stuff getting junked so anybody with a large car or van that can pass by here can probably fill it up. MPS801 Commodore printer Commodore 1525 printer DEC LA50 printer TRS80 model II "8" floppy expansion box" with no drives Compaq portable II TI994a beige version TI994a black version Several MAC Plus and SE (no se-30s) Apple IIc Several C64 and Apple books some in french Some C64s and 1541 drives Untested 1084S monitor Stuff I cant see myself throwing in garbage but would like to see go to a good home : several Atari STs and Amiga 500s...

I only wish the thing was documented so > I could get from Apple OS 7.x and/or A/UX to something like NetBSD on > it. Apple's refusal to document the system was one problem. Another problem I had (that I started griping about during the A/UX 3.0 beta test) was Apple wouldn't let the engineers support the GPi pin on the serial ports under A/UX because not all Macs had the GPi pin. I continuously pointed out that all Macs that could run A/UX *DID* have the GPi pin, and they could allow this to be a configuration option. Without the GPi pin there was no way to have secure dial-in and hardware flow control, which means you really didn't want to have a dial-in connection on your A/UX system. There's a lot of other ways Apple mistreated IIfx owners. -- Eric Dittman dittman(a)dittman.net Check out the DEC Ethusiasts Club at http://www.dittman.net/

DEC DESPO-A Transceiver?

by lipo.ml＠gmx.at

Hi, does anybody know something about the DEC DESPO-A BNC Ethernet Transceiver? Its a small box (about 115*60*35 mm) with a BNC connector and a MMJ connector on the otherside. And ther is a cable wich on one side has the MMJ and on the other side a big black connector (don't know the name) which I have seen at token ring MUAs only. I haven't seen those token ring connectors for ethernet, and no BNC connectors on token rings. So I am a little bit confused about the purpose of these boxes. Looks like a ethernet/tokenring bridge but I don't believe this. Regards, Lipo -- Roland E. Lipovits Vienna, Austria

Final numbers on Apple IIgs computers for sale

by r_beaudry＠hotmail.com

Hello all, First let me say that I hope all of you are all right, and that your lives are as normal as possible given the recent events. I know it's hard to think about old computers at a time like this, but I did at least want to let you all know what was happening. Obviously, if there are any delays in our transactions, I certainly understand ... Take care of what's important first.... Bear in mind that these systems are school surplus. They WILL need cleaning, and many have stickers, sticker residue, magic marker writing, etc. They are all in good physical condition (no rust, no cracks in the cases, etc.), but they all need to be cleaned. Here are the final counts on the IIgs stuff... These are all tested and working: - Qty. 14 ROM 3 IIgs CPUs, with power cord, NO internal cards. - Qty. 8 ROM 01 IIgs CPUs, with power cord, and memory expansion card (only one bank full on each). - Qty. 22 5.25" Floppy Drives, Model # A9M0107, with cable - Qty. 23 3.5" Floppy Drives, Model # A9M0106, with cable - Qty. 12 AppleColor RGB Monitors, Model A2M6014, with power cable AND signal cable (see below ... more available) - Qty. 9 mice, with ADB connector, labelled as Model # A9M0331 - Qty. 7 mice, labelled "Apple Desktop Bus", "Family # G5431" - Qty. 3 Apple Desktop Bus keyboards with cable (see more below) - Qty. 2 Macintosh LC II CPUs, with power cable - Qty. 2 Macintosh Color RGB Monitors, with power AND signal cables - Qty. 2 Apple IIc computers, with power supplies The following are untested: - Qty. 5 Imagewriter II printers, with power AND data cables - Qty. 17 Apple Desktop Bus keyboards and cables I am willing to test the remaining keyboards, and the Imagewriters if people want them. I also can get more monitors, but again, I only want to lug them here and test them if people want them. Please, even if you have responded before, respond with a specific list of what you want. Don't tell me "a complete system", because I have no idea what that means (mouse? 1 floppy? 2 floppies? ROM version? Monitor?). BE SPECIFIC. The two types of mice listed work with the IIgs, but I don't know if either is "correct" in that I don't know which version shipped with the IIgs. Because some items are limited in supply, if I get more offers than items, I will throw names into a hat to decide who gets what. PLEASE INCLUDE A ZIP CODE OR COUNTRY WITH YOUR RESPONSE so I can determine shipping costs... Once you respond with a want list, I will determine if I can fulfill it, then weigh everything, and get a shipping quote. In terms of money and shipment ... Payment must be in US funds, and I accept PayPal, or Money Order (International Money Order for overseas). The cost of each order is a minimum of $5.00 + "shipping". What this means is that a single cable will cost at least $5.00. A complete system will cost at least $5.00. Anything over $5.00 is up to you, bearing in mind that ALL proceeds will be donated back to the school I got the computers from. There is no special priority given to people who donate more money. "Shipping" includes actual postage (USPS from Westminster, MA USA 01473), plus actual cost of boxes and packaging (no more than $5.00, even for a complete system). Monitors and printers will be shipped in SEPARATE boxes from CPUs. If you come to my house to pick them up, you can "cherry-pick" for the best cosmetic condition. Thanks! Rich B.

IBM 1130

by brian＠quarterbyte.com

Good to hear there some other 1130 fans out there! I should have added that we have ten disk cartridges with our 1130. One is labeled "IBM Only" and we hope it's a CE disk. We didn't find any punched card based software other than four IPL (boot) cards. One is labeled "APLIPL" and we have an APL typeball, so we think one of the cartridges has APL on it. However, we're a long way from trying to spin it up to see if the disks are still readable after what must be 20 years. We also have the maintenance manuals and schematics, but no diagnostic software listings. We'd be interested in getting copies of anything you get scanned or OCR'd, Hans. Norm is setting up a boffo website for it all. A grand opening announcement will be coming soon! And as for Jonathan's observation: > Oh my, an 1130! I don't think we've ever encountered such a severe case of > the classic computers disease. Brian, you need help. I don't think we can claim to have the worst case around here, no sirreee. On the other hand, Norm was suggesting that we port the 1130 emulator to the Palm platform and ...

who's got an M88k Aviion?

by red＠bears.org

I'm looking for list members who own functioning M88k-series DG Aviion machines for a research base, so I can finish resurrecting my 310CD. I need some NVRAM information. Let me know if you have one; include the model and graphics type, or at least as much as you know about either. I'll follow up with more information in a week or so, depending on what kind of response I get. Thanks, I'd really appreciate it it! ok r.

UK members - Leicester (Donnington) show

Anyone else going to the Leicester show at Donnington on Friday? Not that the chances of finding anything really classic - as far as computers are concerned, anyhow - are that brilliant. But probably better than the last Ally Pally Rally. Andy

Apple Set Top Box

by mythtech＠Mac.com

>What was that machine? I remember seeing one a while ago and never figuring >out what it was. It was a custom designed interactive TV unit, used for some test program in Texas and I think the UK. I think it was tested in a few schools, but I really don't know how far it went (it was probably slammed out of existance either by cost, or more likely by Channel 1 if it was meant for the educational market). I don't personally know of anyone that has gotten theirs to do anything, although I have read posts of a few people that got theirs to at least boot to an Apple logo screen. Mine just sits (it gets a red "starting up" light, but never gets past that to the yellow "standby" or green "on", or even the red blinking "busted" light). I got mine from a garage sale just recently (paid $5 for it, no remote, no anything, just the unit)... the guy selling it said his son went off to college, and he was getting rid of some of his "junk" he had kicking around the house while his son wasn't there to complain... my guess is, when the son gets home for vacation, he will be mighty pissed off (I also got a vintage 2 foot Godzilla with working shoot out hands and flicking fire breath... paid $2 for that). I have seen them come and go on ebay, usually selling for between $10 and $20 if you want to pick one up. -chris <http://www.mythtech.net>

>By Apple set top box, do you mean the Mac that was black, and had a TV? Or >do you mean that device that was never released, is Apple branded, and >plugged into a TV? Or another machine all together? Can you elaborate? I think he means the black decoder like unit that was never released... at least his flash DIMM description fits the one that I have. (I just need a remote for mine, anyone have one?) Now if I can just find a MacTV (the first thing you mentioned) or a Pippin (the Apple/Bandi "Playstation" like thing), I can be a happy camper. -chris <http://www.mythtech.net>
