I need a couple Seagate ST351A/X hard drives in working condition. If you have some for sale, trade or otherwise let me know soon. Any other IDE drive that will definitely work with a Seagate ST05X controller also wanted in 40 or more megabyte capacity. -------------------------------------------------------------------- Russ Blakeman RB Custom Services / Rt. 1 Box 62E / Harned, KY USA 40144 Phone: (502) 756-1749 Data/Fax:(502) 756-6991 Email: rhblake(a)bbtel.com or rhblake(a)bigfoot.com Website: http://members.tripod.com/~RHBLAKE/ ICQ UIN #1714857 AOL Instant Messenger "RHBLAKEMAN" * Parts/Service/Upgrades and more for MOST Computers* --------------------------------------------------------------------

Mac Portable problems (was Re: Mac Portable batt charger)

--- Markus Blumrich wrote: My portable powers up without the battery inside it as well. I'm assuming by your email address "dartmouth.edu" that you are in Nova Scotia? (If not - pardon my ignorance). If so these machines have probably been subjected to some cold weather. I have lost 2 Mac Portable hard drives to cold weather - I'd put them in the trunk of my car, travel to location X and then fire up the Mac only to learn that the drive didn't work anymore. This was most likely due to condensation inside the drives. ---- Actually, it's Dartmouth College (NH) but I'm telnetting in from Miami, FL because I'm home for the summer. As far as I know, these drives haven't seen cold weather, but it's certainly possible. ---- If I read your post correctly the drives aren't spinning up at all, but they emit noises which make it sound as if they are trying to - in this case they are most likely stuck. I have convinced old hard drives to become 'unstuck' by whacking them on the side. I know it sounds cruel but if the drive isn't working there is nothing to loose. ---- Yeah, I tried that -- it's worked many times before, but not now. (The technician I worked for six years ago used to fix Mac SE's with sticky hard drives by picking up the whole computer and giving it a quick half-spin with a sudden stop -- the torque loosens the lubricant.) ---- Also, when the death chimes sound, is there a picture of a sad mac on the screen with an error number? The error number (if I remember correctly) may be a key indication as to what is happening. If your mac is repeatedly sounding the death chimes it is in some kind of endless loop and you are most likely not getting to the error #. ---- When I let it go long enough, I get a sad mac with error codes which I haven't looked up in the TIL yet. They all translate to some hardware (occasionally software) problem diagnosis. ---- I have also opened the drives and lubricated the 'spindle' or whatever it's called - however doing so allowed dust particles inside the drive. The end result though was a reliable, non sticking drive that works to this day. Perhaps I was lucky... --- end of quote --- Huh, I always thought that opening up a drive would wreck it -- maybe I'll try that with one of them. Thanks. But wait, there's more! New problem. I have an external hard drive attached to the least messed-up Portable, which boots nicely, but anytime I insert a floppy disk, the machine restarts over and over. What triggers it is pushing the tiny white button just inside the floppy (it gets pressed by the disk usually, but I was trying to see what exactly was setting the restart loop in motion, and when I pushed down on that button alone that did it). It WAS working fine with floppies before. Guess the logic board is having problems handling both at once. Aaargh! Three bad drives and now *two* fouled-up motherboards. -- MB

Update on Mac Run

by jrkeys＠concentric.net

So far I have heard from 12 people wanting a total 35 cpu's and 4 monitors. I would have liked to make them a offer this Friday but this is not enough units to purchase it all. This what I will do now, I will connact a scrape dealer I know and offer to buy it all with him only if he allows me to pull the units you guys want first and he gets what's left. This way we all can get our units at a low price with a bulk purchase by the pound. I have not heard back from Eric if his boss is willing sell and the date of the employee sale. I will until Monday to see how many more people want in otherwise the 12 of you will get your items if the sale is a go.

Punch cards (again)

by sinasohn＠ricochet.net

I was watching a local show called New Media News (http://www.newmedianews.com/) last night and they had a bit with Gwen Bell talking about punch cards. She said that they were invented by Hollerith at the end of the last century for use with the census. Was I drunk or did we just go through a whole discussion about the cards being invented for the Jacquard loom? --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

here's a Lisa/Apple /// resource

by Marion.Bates＠Dartmouth.EDU

I'm posting some info I already sent to someone privately. I wanted to get permission from Mr. Craig first, in case he was trying to keep the volume of requests down or something. My apologies for wasted bandwidth if y'all already knew about him -- just trying to help. - MB --- awhile ago, Sam Ismail wrote: Ok, so I'd like to make use of the recent discussion we had concerning hard drive repair and attack the "widget" drive in my Lisa 2/10 to see if I can bring it back to life. Does anybody know where I can find technical info on this drive? A web resource that I don't know about perhaps? --- end of quote --- David T. Craig, email 71533.606(a)compuserve.com, has just about EVERYTHING ever written about/for the Lisa. (Even the Product Introduction Plan!) There's a list of his stuff at http://www.atomicnet.com.au/simon/lisa/LisaLegacy/References.html. While you're there, check out his Lisa Legacy paper. He sent me copies of Lisa repair stuff from Apple, Sun Remarketing, and Larry Pina's "Mac Repair Secrets" book, as well as some historical info and a set of Lisa Office System 3.0 diskettes and LisaTest diagnostic diskettes w/ instructions. He copied the written stuff for ten cents a page and the diskettes for a buck apiece, plus shipping. He also has some stuff for the Apple ///, but I don't know what. Email him for info. If anyone wants Lisa help right away, I can look up error codes and other stuff in the manuals he sent me, and email an answer usually within a day. My 2/10 displayed error 84, which means the boot blocks had been erased, but luckily LisaTest reported no damaged blocks, so all it needs is a low-level format. Sun Remarketing will reformat Widget drives and send them back (which is, according to the manuals, your only hope if LOS installer refuses to do it, as was the case with mine). It costs $75 to have them do it, which includes return shipping. They will install the OS of your choice (LOS or MacWorks, maybe Pascal Workshop but I don't know for sure). Sun Remarketing's phone number is 1-800-821-3221. If you get someone who's never heard of the Lisa or some such nonsense (which happened to me the first time) ask for Brian, ext. 340. He seems to know what's up. -- MB

Mac Portable problems (was Re: Mac Portable batt charger)

by Marion.Bates＠Dartmouth.EDU

--- George Currie wrote: Actually it should power up with the 9v and the power supply. If you have a fresh 9v battery and have the unit plugged in and it still won't come up, then the problem could still be with the drive. Have you tried removing it and seeing if the unit boots? Also, have you tried pressing both the reset and nmi buttons on the side to reset it? --- end of quote --- Yes, it's been powering up with just the AC adapter and 9-volt battery, and it boots fine with the hard drive cable disconnected (it's happy booting from a floppy). I'm pretty sure I tried pressing the side buttons in all sorts of combinations -- what specifically are you describing? Just press them and let go, or hold them down while powering on, etc. ? Thanks for the suggestions. -- MB

Minor Tektronix success story.

I can just imagine running FLEX at 25Mc! Its performance > over a 1Mc 6800 must have been blistering! Warning. Clock speeds may not be comparable. 6800 and friends (including 6502) often do more per cycle than 2901s. That said, the 4052 is a 16 bit system, despite its 8-bit instruction set. The data path is 16 bit throughout, it fetches two byte instructions in a single memory cycle, etc. And Tek do claim some quite impressive performance boosts upgrading from 4051 to 4052 (average gain they claimed was ten times, I think) > Yikes!! I think I may have seen some boards from a system like that one > in a junk heap last week! It used four 2901's eh? Hm, I'm gonna haveto > revisit that particular junque pile . . . Bear in mind Tony Duell's comments - 16 bit systems based around 4 2901s used to be common, but may now be worth grabbing anyway. I must do some more research into the relationship between 4052 and 6800 instruction sets. P.

Macs, IBM systems, roms, etc etc...

by fauradon＠pclink.com

Hi John, I would love to join you in that effort. I am also interested in acquiring on of each unit. Maybe we can poll our resources and make a few people happy in the process. Anyway, Eric if you can find out the actual cost per palette that would be a great indicator of the fund needed. Thank you for flagging this one.
