Sinclair ZX80 / ZX81 / Z88 Forums

Hey all! Some of you already may know who I am - the crazy guy that made the TS-2068 replica (https://sinclairzxworld.com/viewtopic.php?f=14&t=3397). So I have been here asking for help before about the 2068 and here I am again. :lol: This time I am going to try to build a ZX-Spectrum replica and re...

Nice fake you have there, by the way! :) Thanks! It looks even better in the flesh. A very nice little curio. I love fakes (in the good sense). I have made my own TS-2068 fake a few months back (https://sinclairzxworld.com/viewtopic.php?f=14&t=3397). If those microdrive cartridges were easy to rema...

Not a big surprise to get awesome print results with all the current color laser printers. I use them all the time. But I am not referring to those cheapo ones anyone can buy for a couple hundred dollars to put aside the computer, instead I am talking about those several thousands of dollars huge an...

I don't know if some member from Brazil has had the interest of start such thread, so please forgive me if I am digging an old subject up. I started my computer life with a Sinclair computer as many of us here BUT I did not this with the original stuff. The reason is because in the 1980s we had a Br...

I found online something alike the board I had...



Mine was not compact as this one though.

That's strange that the TC2068 needed a compatibility cartridge. When I had a TS2068, I exchanged the ROM for the TC2068 to gain back the Spectrum compatibility and it worked well. Actually the cartridge WAS just exactly what you said: a small board with a Spectrum ROM to bypass the original one. I...

Hey all! I am glad that you enjoyed it! It's a pity that I didn't document the making off of it. The reason is that I didn't believe that I would finish the project (I have this problem of starting and never finish things), but I can shortly describe how it was done: FIRST STEP - I started finding t...

It was pointless to make it incompatible with the Spectrum, because that meant it would have no software. Of course that made it 100% a market failure. I agree with you. But we should keep in mind that it was the 80s. The personal computing history was just beginning and there wasn't yet a consensu...

Aside the fact that the TS-2068 is too much more fancy (IMO) let's see the facts... I had a TS-2068 several years ago and what I can tell you is that the main (and annoying) difference is that they have distinct code in ROM - mainly the addresses - meaning that the 2068 will NOT run ZX Spectrum asse...

I would like to thank everyone that helped me. The project was finished a few months ago, and the result is here: viewtopic.php?f=14&t=3397
