Lenovo Laptops

Ops, Lenovo :P >> >> Lenovo Thinkpad laptops sadly are sliding towards 'plastic crap' and >> away from the 'solid built IBM quality' end of the scale. I have 3 Lenovo laptops in my possession, a T61 (from a former employer) a T420 (on-loan from a current customer) and a G550. They have consumer-grade and commercial-grade lines, with the T-series being the commercial-grade. The T420 still seems of excellent quality, even when compared to the T60/T61-era machines, and the T43 (T60 precursor and last of the IBM-branded stuff.) It has been sad to see them go from metal (magnesium?) casing to plastic over the years, but IBM had already initiated that change, IIRC. Given the abuse I've put my T61 through (weekly commutes from IND to YUL, IND to MSP, etc.) it has my vote of being a solid laptop. I don't see the T420 (current Lenovo) straying too far from that mark. Both my "T" systems run Windows 7. The "G" system is running Windows 8 preview. The G550 is another story. It's a consumer-grade system with a 16:9 screen and 1366x768 resolution. It's body is solid enough, but I've managed to have my DVD-ROM drive bezel pop off and go MIA. I can use it for browsing the internet, but not much else.

IBM docs in Chicago are safe

by wdonzelli＠gmail.com

I have now confirmed that one of the mainframe guys has rescued the IBM docs. Thanks all for offers of help. You may eventually be called for duty again, as there is apparently a whole bunch of microfiche there than needs to be rescued as well. I do not know the details, nor the urgency. -- Will

Raspberry Pi and America, was Re: ST-506/412 to IDE/ATA/SCSI/? adaptor

by md.benson＠gmail.com

The key point behind it is the price is well on the right side of the price threshold between 'I'd like one but it's a bit too much' (about 40-50 GBP in my case) and 'That's cheap and looks good, I'll have one' (about 25GBP in my case). That's an important factor and why demand is so high (a little too high at the moment). Also yep there's more cost for extras but they, as many pointed out, are requisite for any board you buy, so a more expensive board shoves the total price point up by the comparative amount. In this case cheap means 'less than most other equivalents' not 'it's only 35 bucks!!'. The third factor is that by the time I had mine all the files, tutorials, etc. I meeded to get it going inside 2 hours were on hand. Last time I bought a minature ARM dev board I paid a lit more and it went back in the box after a couple of days because I couldn't find the stuff I needed to get it going (it was a few years ago) Raspberry Pi has been the dismetric opposite. Satisfyingly inexpensive, easy to setup and use. Now mine is running 24/7 pretending to be a VAX. The whole lot including extras cost me less than 50 GBP. Mark me satisfied. -- Mark Benson http://markbenson.org/blog http://twitter.com/MDBenson

IBM (Sony) 6091 19 monitor

by rampaginggreenhulk＠yahoo.com

I figured I'd pay my last respects before these got chucked. Could be in better shape cosmetically (but, uh, everything about a monitor is cosmetic, no?), but they were working the last time I turned them on. I used to get big bucks for these bad boys. But their day has long come and gone :(. Damned LCDs!

IMSAI switch paddle replacements

by dgriffi＠cs.csubak.edu

Can someone point me to a source for replacement switch paddles for the IMSAI 8080? Todd Fischer of imsai.net tells me that he has red ones, but no blue ones left. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

Modern computers with docs

Really, if put on paper, it ought to fill a large room. The last machines I ever saw where schematics were available to the end users were the VAX-11/780 and the uVAX-II. The 780 schematics were as thick as a phone book and 11 x 17" pages. The uVAX-II was a lot smaller, it was a hierarchical description, but gave a lot of insight on how the processor and interface chips were organized. Jon

RCA/COSMAC 1802 assemblers in the 70's

by hilpert＠cs.ubc.ca

Does anyone recall anything about the availability of (cross-) assemblers for 1802 development back in their day? Not that I need to find an original, I'm disassembling and 'reverse- sourcing' the firmware (~700 bytes) for some equipment from 1977 with an embedded 1802, and just idly assessing what the likelihood is that it was produced with a machine assembler vs. hand-assembled.
