I have recently come upon a collection of Byte Magazines from 1976
through to about 1986. It is not complete, that is I do not have every
issue across that time span. But the collection is pretty comprehensive.
I have a scanner with an auto document feeder. I'd like to scan this
material in and post it online as a collection of jpgs. However, to do
this well would require destroying the bindings of each magazine in order
to get a completely flat scan of each page.
- Is it wrong to destroy these magazines in order to scan them
in for posterity?
- Are they as rare as I think? That is, are there plenty of copies
around such that historians and others interested in classic computing
would not find this project of interest?
- Is the copyright violation involved (on 25 - 30 year old magazines)
really an issue?

Here's a question for the list - how many still have and use the TI
calculator that could be used in octal or hex?
By coincidence, I just happen to have my TI Programmer in front
of me, in the process of replacing its NiCds.
I used to use my Casio fx-451 (the solar powered one) a fair bit
(easier than the TI to read & doesn't need an AC adapter), but lately
I've found the Windows Calculator to be the most convenient
(nicer keyboard & display and doesn't take any desk space).

"Most"? I don't think so. 2 billion ARM/XScale cores licensed in the
last 12 months, and about a quarter that number of MIPS chips/cores.
Pentiums don't even come close.

I'm checking through some of my old stuff and I have a Fluke TK80A, which
appears to be a single board computer or training system. It has an 8080
CPU, 1K of RAM (2114), an EPROM and a membrane keypad, some 7-seg LEDs and a
few switches. Other than the power connector it has no external connecters
or sockets - so I assume it's a standalone system.
Some of the LEDs and switches are stamped "ADDR 10000 Output Port" and other
addresses that are over 10000 (ie 100F9)- which has me perplexed as the
address limit of the 8080 is FFFF and the IO range only goes to FF?
I'm going to check it over and apply some power to see what it does (if
anything). However, if anyone has heard of this board or know something
about it could you please illuminate me to its purpose?

It's similar here in the UK. Moreover, every photocopier in our
University, and in others I've seen, has a notice beside it stating the
rules, and spelling out what the allowed "fair use" exceptions are.

No problem; just move the printer! ;->
The Windows Calculator (am I breaking any rules here? :) does indeed
have shortcomings, but there are some pretty useful others out there
with all your logic functions, 4/8/16/32 bit modes, ASCII and unit
And for accounting stuff, a printing calc is indeed useful; use one myself for
certain things. I was just musing that in general people seem to be more
comfortable with calculators (even non-printing ones) than computer versions.
(And looking for and correcting errors in long columns of figures is a lot more
convenient in a spreadsheet.)
>Often I need the result when NOT at a PC.
Aw, c'mon Allison (and Tony); someone asked whether anyone still had a TI Programmer
and I replied, yes, I do but generally use the Windows calculator instead (because
of some of the same shortcomings you yourself mentioned); aside from the
obligatory "*I* don't _use_ Winblows" replies there were one or two saying that it
and computer calcs in general were "a pain" ("can't see the point") and I asked why.
I didn't say that they were "better" or that you should throw your pocket calc away
and use a laptop when you're away from your desk. Just that for the usual
_programming_ stuff, converting bases & doing hex/octal/binary arithmetic,
it's convenient to have a calculator right there on the same keyboard that
you're programming on (and perhaps one or two people weren't aware that
the Win Calc has hex & binary (and octal, the thread of this discussion) modes;
I know that I didn't realize it until well into W98).
I was helping a fellow with a writeup on the CDC STAR-100 (circa 1974) and
stumbled across some of the old manuals on bitsavers.
You know, back in 1975, the machine was arguably the fastest in the world
(I won't get into benchmark results, but it was definitely in competition
with Cray). I'd forgotten that the maximum memory available was a megaword
(64-bit words) and that standard was half a meg.
Back around then, being able to run linpack really fast mattered a lot--and
gave rise to oddball ventures like Saxpy (the company, not the subroutine,
although the two are not unrelated).
Consider that that's 8MB by today's standards, barely enough to host
Windows 98. On the other hand, the CPU is still pretty complex by today's
standards--and we had 256 64-bit registers to work with.
I guess it's like one's childhood home. When you return decades later to
visit, you can't get over how SMALL everything seems.

In 1995, I was unable to buy mercury cells for my Konica 35mm SLR. I _was_
able to find a set at a store in Christchurch, NZ. Dunno if they are
there or not.
seen a real old post about chip programming
noticed you had a data i/o 29b
I have been looking for information abtou this programmer as I am looking into buy a porgrammer and everyone keeps telling me I shoudl ge thtis type with a unipak 2b
but seems noone will tell me what I will need to use this system as in drivers ....front end since data i/o no longer give help for this item I must rely on someone that has one to help me out ...there are a few on ebay and im thinking of getting one but none of the sellers are the users so can not tell me anythign about them other than they passed self tests...
either way if there is anyway you can help me out least maybe tell mewhere drivers and or front end can be downloaded or somthign would be great..
