My sick A600 = dead

by aliensrcooluk＠yahoo.co.uk

Sadly things have taken a turn to the graveyard... I hadn't been able to find the time to see what the original problem was caused by. A few weeks ago I no ticed that the floppies started coming out of the in ternal floppy drive warm on the underside. Today when I switched her on I heard a click sound ( no, not the switch button, another click) and when I started to see a slight whisp of smoke coming out f rom the floppy drive I knew something was seriously wrong and switched her off. I daren't switch her back on and will have to remove the harddrive and open up my 2nd A600, even if it m eans breaking those damn clips at the back. This comes after a few weeks of long working days (8 to 8.5 hours) when I should only be doing 7 hours a day. I am not a happy man at present. Regards, Andrew B aliensrcooluk at yahoo.co.uk

Need an obituary for Don Tarbell

by webmaster＠rcworks.com

While I met Don briefly a few times my father would be probably the one that knew him best. My father was with him from conception of the cassette interface up to his death. My pop might be open to writing what you want, you should ask him. If your still in need of an obituary let me know and I will give you my dads email address.

DEC 57-27889-01 Chip, what was it used in?

by fm.arnold＠gmx.net

Hi, someone offers on Ebay this chip-carrier (#130038367943) It looks like the CIS-option fot the 11/23B and 11/24 processors, but there are only 5 chips on it. Who knows this piece of HW, what was it used for in which devices? Thanks, Frank -- Computerese Irregular Verb Conjugation: - I have preferences. - You have biases. - He/She has prejudices.

Finding bad RAM chip on PDP11 M7551?

by derschjo＠msu.edu

I have a MicroPDP 11/73 I'm trying to get running again; it has a single M7551-AP memory board (1MB) which appears to have a stuck bit; the startup memory test fails with: Expected Data = 125252 Bad Data = 125253 Address = 01400010 Any ideas how to determine which RAM chip needs to be replaced based on the failing address? Thanks, Josh

UK rescue: Domesday + Acorn stuff (Camberley / Gillingham, Dorset)

by julesrichardsonuk＠yahoo.co.uk

I've just been contacted by a chap who posted to one of the Acorn usenet groups the other day - he has a range of stuff available, including a Domesday system player / disc / manual, 3 x Master 128 machines, and a selection of Cambridge Workstation software and manuals. Unfortunately his deadline for moving it is Monday, and all the people who have responded to his usenet post have let him down. Master 128 machines are common enough, but the rest is reasonably rare. Is anyone able to rescue this lot either for the museum, or for themselves? Whilst we'd welcome the Domesday and Cambridge Workstation stuff at the museum, I'm more interested in the rarer bits not going to landfill than anything. The guy lives in Gillingham (the Dorset one, not any of the others) and works in Camberley, so it seems like a pickup can be sorted out from either location. Original usenet post with a more comprehensive list is here: http://tinyurl.com/y4qv5t If anyone can help, that'd be great and I can put you in touch with the owner; unfortunately there's not a lot more I can do from the wrong side of the pond, and our one guy who lives close to Camberley is away right now... :-( cheers Jules -- If you've ever wondered how you get triangles from a cow You need buttermilk and cheese, and an equilateral chainsaw

Faraday cages

by jonas.otter＠gmail.com

A Faraday cage need not be made of solid metal, it depends on which frequencies you want to keep out (or in). The important thing is that any holes need to be smaller than any wavelength you want blocked. Also, slots and holes can act as antennae, so there are other restrictions as well, but essentially, the idea is to keep the holes small enough.

150 something for disk drive, how about $25,000 for a Kaypro?

by jwstephens＠msm.umr.edu

It hasn't sold, but has two declied offers on it. I have heard of overpricing, but this is pretty much one of the highest I have ever seen. He claims serial number 000003 or such. Anyone know how kaypro serialized their units? Is this really the third Kaypro-II. It isn't an Apple 1, which would demand some sort of premium like this, however, and I wonder if the S/N if it is for anything is for the "test set" he says it is part of, rather than the unit.

OT: microsoft browser virus!

by evan＠snarc.net

I use Firefox 99% of the time, but tonight I decided to update IE 6 to the brand-new IE 7. So I opened Firefox, went to Microsoft.com, clicked the update button for IE on their homepage, and .... absolutely nothing happened. I guess they block FF. Not surprising, but no big deal. Instead I opened IE 6.x, again went to Microsoft.com, clicked the same update button, and .... my anti-virus scanner (Alwil Software' Avast, which I highly recommend) immediately popped up! It read the Microsoft download as a virus and it urged me to abort the connection. I rebooted and tried it again with the same results. It cites "VBS: zulu" as the culprit.
