This might be useful to those trying to emulate, make there own roms, or need to know whats going on. This is the complete disaseembly of the so called kick disks, soft kick, kick start disk that from what I know only the Amiga 1000 really needed, the very earliest Amigas with no kickstart in roms onboard (A1000?), 1.2 as a rom came later. This is taken from version 1.2.
A quite full guide on how to write device drivers for Amigas fitted with pre 1.3 ROM's. I would assume the A1000 and early A500's, this info should be relevant for kickstart 1.3 machines too. The author does mention that kickstart rom v2.0 might break some functions that he would not have known in 1990 when he wrote the guide but today we know that statement is true, so use it as a reference only.
Apple iPhone 6 Plus size compared to the Samsung Galaxy Note 3, interestingly Samsung taking a stab at Apples new iPhone 6, however the pic reveals that the Samsung Galaxy to have the bigger screen at least to my eyes.
Stumbled across this strange little project which seems to be a attempt to list all the payphones world wide they can. Users send in the number and location of the pay phone and it gets listed. Sadly the last few times I tried to phone a box in the UK I never got thru, I think most dont accept incoming calls no more :(
Service manual, referance manual and schematics for the Acorn Archimedes model 3000 RISC home computers. Might be useful to someone, these manuals seem to be digital copies so the quality is quite good.

Motorola holds a special place in many peoples hearts for differing reasons, theres a very high chance you ran into there CPU's which were used in basically everything. Low price and high performance for there time and cost, easy to work with and ton's of documentation. Today I found a article called "What happened to Motorola" it seems to focus on there mobile/telecom buisness, but it got me thinking what did actually happen to Motorola?
Motorola 68000 series CPU.
Why does Windows seem to detect certain devices as a toaster? Well theres actually a really good reason for this. It stems from the use of fictional companies in Microsoft documentation that are used to training and development purposes. In the case of the toaster appearing its basically down to a rushed hack job of a driver that was altered just enough to make it work, still nice to see though.
Interesting techinical meddling here, the author of this hack was given a Motorola 68008 CPU and then decided to get it to do something in this case blink a LED. He used a Arduino to boot strap it and get it going, uploading the code and running on the CPU. A interesting read even if your not into doing strange things with obsolete CPU's, covers some technical aspects of the CPU, the Arduino, EEPROMs, and all the problems this mash up created.
Since we posted the Amiga documentation yesterday it seems only fair that some Atari stuff gets thrown up today. Here is a site I have used in the past, its full of all kinds of documents on Atari hardware and software. The site covers the ST range (ST/STFM/STE/Falcon/Mega etc.) the schematics are particularly useful.

The Amiga had some lesser known file formats that never really made it to other systems, at least not in well known or used kind of way. Here is some documention and information on those formats. Never know when this stuff will come in handy.
While reading a article about the missing Pinball game from later versions I noticed there was a mention of HyperTerminal being missing from later copies of Windows also. Now here we are struggling to keep alive the Windows XP and Windows 2000 based machines which we need for various bits of equipment where the software will just not work correctly on anything later think eprom programmers, jtag devices, logic analyzers although fairly modern there mostly USB the software side however is a tad fiddly, and the hardware issue of new PC's lacking serial & parallel ports is not helping matters. Anyhow this mention of HyperTerminal being missing intrigues me so I looked into it and found some solutions. There seems to be no mention as to why its missing some sites say 64 bit issues other sites say its a legal/licensing thing.
Found this site to use as a quick look up tool/referance when using various programming languages it seems to have most of them covered. Works in your browser so platform independent, a good alternative to some desktop based programs that do exactly the same thing but I can't remember there name right now. Worth a look if your into that sort of thing.
Heres a very interesting write up on one guys attempt to rescue all the data from a broken SD card, the story shows some interesting methods with both the hardware and the sofware, also some good explanation on how these things actually work. While it may be easy to just straight out dump the flash putting it back together is not and those pesky on board controllers getting in the way...
Commodore 1530 tape deck gets a upgraded retro style counter. These decks were very popular in the UK not so much anywhere else it seems, probably because they were cheap and 60% (varible -/+ 50%) of the time worked well enough for peoples uses. Sadly now made obsolete by various tape deck/disk drive emulators/adaptors made with cheap off the shelf IDE parts and SD cards I guess we will never see a faster, better, more reliable tape deck version.
The source page is in German.

Interesting home made Arduino based Commodore 64 cart dumper, very simple not alot of parts needed, dirt cheap considering the cost of the Arduinos, author says it works well with standard carts. The author needed to do this in this case because there was no known dump of the cart available on line.
Microsoft has released the source code for some older versions of MS-DOS (1.1 & 2.0) and Word for Windows. Might be of use to some people, mainly those over 30 I would guess. Be interesting to see where this leads.
Very worrying things are going on with the popular software encyption software TrueCrypt . According to the now redirected website the developers have ceased working on it because Microsoft dropped support for XP... that makes no sense to me, they say that Windows Vista/7/8 (other platforms?) have built in full disk encryption so they see no need for TrueCrypt. The site now points to a page on SourceForge with instructions for migrating to BitLocker. There is a final version of the software on the domain v7.2 which can only decrypt old TrueCrypt volumes and drives (?) I was kind of hoping this was some hack & defacement but a while has passed and it seems its pointing to the end.
Wish I had thought of this would have made life alot easier. Simply SMD soldering iron adaptor made from a bit of copper wire. Looks simply enough to do.
