Re: Is vintage hardware better able to survive an EMP event?
I believe even vintage cars say 1920s to the 70's would still be affected as they posses an ignition coil, regulator box and spark plugs etc and in the main they also had electrical fuel pumps ( think Morris Minors, Austins various etc) so they would be knocked out. Early diesels ( lorries? ) with m...

Re: Wednesday 3 am quiz: Software houses by street view building
Not forgetting Kaydee, also in Yarmouth. Allegedly set up by a disgruntled family member from DK Tronics hence the reversed phonetically sounding name. The keys, keycaps and legends were the same on both DK's and Kaydee's external keyboards and their UDG boards shared identical content barring set 5...

Re: Currah Microspeech
A plane mono ext cable would be best bet as the units chip is mono. A mono socket to 2 flying mono leads is a bit of an odd ball with no ready use generally and not readily for sale I would have thought. Stereo socket to 2 mono leads yes but a mono socket to 2 mono leads not really unless, for your ...

Re: Currah Microspeech
Just tried my own Micro-speech by plugging the 3.5mm lead into the microphone socket of my tower system and it works perfectly. Looked at the signal level in Audacity and it's quite a strong one which needed to be turned down to nearly zero to stop it red lining. I can only suggest you do something ...

Re: Currah Microspeech
Yup, ran across this website also. You might be right about a signal below line level. But I am actually plugging it into Tascam digital portastudio which acts as an amplifier. What would be a proper way to output audio from its 3.5mm lead without modding it then? If memory serves the inputs on som...

Re: Currah Microspeech
Possibly because you are plugging it into something that expects a line level signal (300-450mv domestic 750+ mv professional line level.) The instruction manual says to record speech plug it into the MIC socket of a tape recorder which usually is for microphones with a weak output, this suggests to...

Re: Issues changing email address on other site (WoS)
Just my two bobs worth.
Iv'e known Mark from the ZX81 forum for the last 13 years and not only has he been thoroughly helpful over all this time I personally would trust him with my details for recovering my WOS account based on all my interactions with him.

I find that any forum using phpBB software suffers the same thing re the searches and common words problems, ( I'm a member on three others) The common word thing is irksome as you have to pad out the search terms with extraneous words which the search function homes in on rather than what you are a...

Re: Timex Sinclair 2040 printer question
The power supply output needs to be AC not DC and is rectified and regulated inside the printer itself. The website in the link in the post above says that you can buy fax paper and cut it down but there is no need as rolls of the right width are readily available, picture is of one of mine, and whi...

Re: Purely theoretical ROM swap
I couldn't say what would be the result re the Spectrum, but I have converted a few ZX81's into ZX80's ( as I didn't fancy paying half a grand for a "doesn't power up not tested no returns" piece of drek) This involved fitting a few resistors to various pins on the CPU to stop the NMI from...

Re: Abersoft fig-Forth Recompiled
Just to make certain I reloaded a fresh copy of the emulator (Fuse) and now it all works perfectly with large integers!! I also tried two other emulators and all ok with them also so can only assume I had a corruption in the emulator as all is ok and to confirm I have just run a primes routine to fi...

Re: Abersoft fig-Forth Recompiled
Then it must be something else causing a reset when using large integers in the Josephus problem, sadly I don't have the skills to solve this.

The Josephus problem if you are not familiar with it can be found here... https://en.wikipedia.org/wiki/Josephus_problem Not a great problem but with large enough numbers a good speed test I have found. Usually in this example a smaller number is used usually in double figures. This code worked in y...

Re: Abersoft fig-Forth Recompiled
I'm enjoying this thread quite a lot as Forth is my thing for computation, Forth79 in my case on the ZX81 and it's been fun comparing the two. Computation wise this is a fair bit slower than the ZX81 and not as fully featured and this latest version has introduced one bug at least which I suspect li...
