Where Standard 1401 or 1401plus are mentioned, they will be usable, but significant features of the software may not be available.
We have tried as hard as possible to make sure that the information on Windows version compatibility is correct, but there may be circumstances where old software with new Windows versions (or vice-versa) give problems.
The complete list of 1401 types (in order of development) is: Standard 1401, 1401plus, Micro1401 mk 1, Power1401 mk 1, Micro1401 mk 2, Power1401 mk 2, Micro-3, Power-3, Power-3A
The latest versions of Spike2 and Signal require the SSE2 instruction set extension to the IA32 (x86) instruction set. It started to be added to Intel 32-bit CPUs in 2000 and to AMD CPUs in 2003. All 64-bit capable CPUs support this. The following link has a little more information:

CED, through this site, does two things that relate to privacy. We would like to explain them.
We offer free down-loads of many files on our site, from test programs to complete install files for updated versions of major packages like Spike2 and Signal.
When customers wish to take a down-load of a major package, we ask a few questions, including their name, email address, the serial number of the software for which they seek an upgrade and whether they would like an automatic email whenever we update the product. This information is emailed back to CED when they access the final down-load screen. Within this email, your browser transmits the type and version of browser you are using, and the screen resolution you are running.
The reasons why we take and keep this information are that it is useful for our software development team to know who has taken the latest versions, and it is useful for our web site development team to know which browsers people are using to view our site, and what resolution they have their screens set to.
When people down-load a major package, we try to write a cookie, a small file in your computer, that records your name, serial number of the software package, and the version you are down-loading. These files have a lifetime of one year.
The reasons for storing this information are firstly that if you ask for another down-load some other time, your details are read from the cookie and are pre-written into the form, to save you looking them up again. The other reason is that next time you access our site, your browser looks through your CED cookies and compares the versions down-loaded with the latest version numbers read from our site. If there is a later version of a product you have already down-loaded, we tell you on the home page screen, so you know that it is worth going to the down-load page again.
None of this information is ever given to anyone outside CED. ×
