John TITOR - LOOKING FOR IBM 5100

[dambld]

             :-/ :-/ :-/

To the GURU's I'd like to find an old IBM 5100 it is suppose to be able to interface with unix with right tweaks If you want to know more seach John Titor  your self - and I'm sure there are people working on this stuff right now any hints on finding this hard ware and anything you know about tweaks please reply

This is a great form for help - even if this an off the wall question it is it is worth the look considering UNIX experation Date similiar to Y2K because of engineering limate at the time of design

You can probably find one at the obsolete computer musuem or Ebay. Considering the fact that this 30 year old portable computer weighed 50 pounds, cost 10K usd, had 64KB, and used a subset of the IBM-360 operating system, the Y2K tweak would be the least of your worries.

Thank you for reply I hope you are aware of "john TITOR " intresting read yes I know I"m looking for dinosaur ,but I stand a better chance understanding the relation between unix and dos, this unique feature of 5100 is suppose to be available now which would beg the next question how would some one be aware of this feature unless it is required? I started this thead to build information when I read between the lines of the post by "JT" I see it as a call for help.

sub system info relevant thanks TWEAK works other way around 5100 is to help recover unix systems in future 2038 when clock expires do to physical design of unix at birth. go a head ask me how I would know such a thing :-/

The time stamp variable is 32 bits long. Only 31 of these bits are used to store the number of seconds. The maximum number of seconds that can be accommodated is therefore 2,147,483,647. (I'll let you do the math)

Unix keeps track of dates by measuring seconds from Jan 1, 1970. I'm guessing that the number of seconds elapsed from Jan 1, 1970 will bring you into the year 2038 when the timestamp variable overflows.

Now that 64 bit computers are here, it's doubtful we'll all be here when the next overflow occurs.

Hope this helps.
