I collect them to go with the old computers I collect. I hate using old iron with new monitors. Doesn't seem right somehow. And, I have a real hatred of LCD monitors. CRT's have much better picture, IMHO. > For my part, today I'm taking a fixed-frequency HP > workstation > monitor down to the recyclers.

For one, that's exactly the kind of monitor I've been looking for for a long time now, and for two - it's important to preserve this kind of hardware. I mean, sure, you _can_ use an LCD with an old HP workstation, but would you want to? Not exactly accurate, if you ask me. -Ian

IBM Thinkpad 600e can't get past password prompt...

by alhartman＠yahoo.com

Dan, You seem to be missing the point of my request for help. 1. The laptop is worth about $50.00, I'm not spending $1200 to recover data off the HDD, and neither is my friend who it belongs to. She is upset losing the $100 it cost her two years ago. 2. The laptop doesn't boot. It asks for a password. This is in the BIOS. It can't be bypassed to boot from floppy or CD. Without this password, the system is bricked. There is no way to recover it other than changing the logic board and HDD. Since all I want is the HDD data, that is not the solution. There is a way to recover the password, but nobody will tell me where the TPM chip is located on the 600e logic board. I don't want to just take the laptop totally apart. I want to take as little apart as possible. I'm hoping someone knows the IBM master password so I can get into the bios and reset the system. Barring that, this system is junk. Thanks anyway. ----- Original Message ---- Date: Thu, 18 Jun 2009 18:06:28 -0400 From: Dan Gahlinger <dgahling at hotmail.com> take it to a data recovery place, ask for a free estimate. be prepared to pay $1200 or more. as for the CMOS, you can still wipe it. remove the HDD, then boot either floppy or CD that would bypass that password, would also confirm exactly how it is locked. you can still try to contact IBM for recovery (for a large fee I suspect) otherwise you're SOL Dan.

Yes that's right. The University of London twisted ICT's arm by saying if they did not fulfil the order, there would not be any undergraduate intake in 1962 and they would make sure everybody knew who was to blame. ICT made an extra prototype machine and shipped it. Every few weeks a group of engineers would come out and spend a day fitting the latest modifications to the prototype to bring it up to date. Students were not allowed anywhere near the machine, it was used purely for administrative purposes, plus putting examination results into grades and printing the pass slips and certificates. On de-commissioning it was offered to some engineering students who ran it as a bureaux come commune (this was the 1960s) on a what customers could afford basis. For instance it handled the membership list of the legalise cannabis movement which could not afford much but did not want their data got at by the authorities. That generated a few problems with the powers that be for the then owners. I bought it from them around 1977. > > That is a truly major score. That's freaking HISTORIC. Good lord, do > you store it in your house? It would not fit in my house. It is in a barn that used to be used for breeding rabbits (there's a job you'd think was easy) until they were wiped out by myxomatosis and the owners went bust. > How much power does it use? 13kVA three phase.

IBM Thinkpad 600e can't get past password prompt...

by amouses＠gmail.com

Well a lot could be said about passwords! I have not seen all the posts but you need to clearly say the exact 4 digit IBM machine type and additional submodel code so everybody clearly knows the exact laptop you are fixing. Also identify which password you are trying to recover. I suggest the first point of call is the maintenance manual here IBM Thinkpad 600E maintenance manual http://www.linuxfocus.org/~guido/gentoo-tp600e/600e_hw_maintenance_manual.p… This will tell you about the different passwords: e.g. Power-On, Supervisor, Hard Disk .... It appears that for a 600E you can reset the Power On Password by shorting pads onthe motherboard. --------- I did find an entertaining article about hacking the Supervisor password http://sodoityourself.com/hacking-ibm-thinkpad-bios-password/ This sounds ideal if you really like soldering and have a lot of free time on your hands. Let us all know how you get on! PS: As an aside, if anybody has a good article on how exactly hard disk passwords work, please post the link. I never quite figured out the exact mechanism of storing the HDD password, and communicating it to the BIOS/OS on first access. regards marcus b.

But who would even want to complain about the cheap and cheerful Speccy? At only 175ukp in 1982 it was cheaper than a modern netbook and single- handedly put computers into the sticky, but impoverished hands of around 2% of Brits. You gotta give'em a bit of Kudos ;-) !

hp laserjet 4si

by james＠jfc.org.uk

does anyone in the UK want one of these? it has postscript support, a duplex unit and a jet direct card. it was working fine until last week when it started displaying a "54 service" error. i have a spare maintenance kit (with fuser) and an unused toner cartridge for it. i expect the maintenance kit would get it going again, but to be honest i'd rather free up the (considerable) space. this would be pickup only from york.? it would be yorkshire's favourite price, of course. i'll help you carry it downstairs too! if you want it, let me know within the next week, or it might find a less loving home... -- James F.

Doing DU0 bootable with RT11 5.3 from one TU58

by spedraja＠ono.com

Hello. I started one virtual TU58 with RT11 5.3 from the COM1 of my laptop in my PDP-11/23 PLUS using TU58EM. In the same machine I have one DILOG DQ696 with one ESDI hard drive of 768 Mb. I want to convert the ESDI drive in a bootable device with RT11. I've initialized the DU0 and copied the complete system from the DD0 (TU58) Searching for the fast path to continue... Someone knows what must I do exactly now to continue ? Thanks in advance. Regards Sergio
