Sinclair ZX80 / ZX81 / Z88 Forums

Hello again,

I forgot to mention that my display also shows Ver 1.20.

Hi jojo, the buttons on my 1.18 version work as expected, the only time I have to press double is when pressing the play button as it pauses the load function when pressing play the first time, simply pressing play again will load the software. I have now tested it on my zx spectrum +2 and my oric 1...

Hi jojo, Glad you got it working! I have just installed ver 1.18 on my TZXDuino (I couldn’t find 1.19) To get this to work, you will need to change the code in the very last line of the userconfig.h (as well as the same OLED1306 modifications you did earlier on the 1.17 code) I downloaded the 1.18 f...

Hi there, I hope so too, programming Arduinos can be a pain if you don't know which libraries you require, there is also the problem with the configuration for the different types of display. I thought about using a pro mini with my design but decided against it for a couple of reasons; the first be...

Hi all, just noticed this thread and thought I would try to help out a wee bit with those struggling to write the firmware to the Arduino nano. There are a couple of options available to you; the first one is fool proof but it doesn’t boast the latest firmware update for the TZX Duino. I have a Yout...

Hi all I hope you don’t mind my sharing with you the latest mod I have done on my ZX Spectrum +2 (grey) This mod was relatively easy to do and I have included every single step in my blog https://alleged-geek.blogspot.com/2021/ ... g-fix.html at the end of the blog entry I have included a Youtube cl...

Hi all, I have just finished my latest project on my +2; the umbrella fix! This one was good fun as it gave me the chance to dig out my eprom programmer to program the GAL16V8D IC. Many thanks to the clever folks at velesoft.speccy.cz for making their modification public. I have included a youtube l...

Hi all, I have been going through my old 8 bits recently and have turned my attention to my ‘spare’ ZX Spectrum +2 which I won at an auction here in Aberdeen for the staggering price of £5! My main complaint about the +2 is the fact that it was very temperamental when loading from an external source...

Hi all, reading this thread with interest; I also bought a TZXDuino on ebay (not the enclosed one as shown earlier) but a slightly different version on a PCB. Although it worked flawlessly and was a pretty good price (I think I paid about £17 for it) I didnt like the fact that there were components ...

Thank you for the welcome.... good to know that there are others out there who "also dont have any other 8-bit computers"
