Re: New member from Oregon, USA

Thanks, Moggy. Like my 3K Ram Pack reproduction and ZXpand enclosures, sometimes I just have to do something because no one had ever done it before, as well as trying to fill a need amongst Zeddy owners. All the things you mentioned about the printer are indeed spot-on, but still this is something I...

Re: New member from Oregon, USA

"and if the 3d belt thing ever sees a successful light of day I will change my name to Betty" Well, I hate to inform Moggy that I now have a ZX printer to further proof out my belt design that has already had a successful tryout. Matter of fact, the .STL was posted to the forum a few months back, th...

By slow, I was referring to in comparison to the Atari 2600.

Re: PONG with AI clone ?

My guess is that it would be pretty s-l-o-w. Might still be interesting, though.

Re: Using a paint stripper heat gun to de-solder?

Update. My efforts to heat a copper block to melt the solder on socket pins was a total failure. Even after heating the block for several minutes with a propane torch it never got hot enough to melt solder. Would apparently need a furnace to get it hot enough.

One scrapped PCB.

Re: New member from Oregon, USA

Andy has only made a hundred or so. He's probably still recovering from the soldering fumes if he hasn't already given himself dain brammage. :lol:

Re: Using a paint stripper heat gun to de-solder?

I have a PCB that I somehow managed to solder the chip sockets to the wrong side of the board (old age is unkind at times). After considering using a solder sucker, heat gun, etc. to free them from the board I am going try something a little different. I bought a 1x1x2 block of copper that matches t...

Re: zx80 clone which is the best most accurate?

Yes, it is the same guy (Plamen) who did the Jupiter ACE. Hopefully my experience will go as well as yours and Phill's, assuming everything was to your satisfaction. I can 3D print my own case, but maybe this will get me motivated to get back to work on my vacuum forming project. I have the decal fi...

Re: zx80 clone which is the best most accurate?

I am waiting on the arrival of the reproduction kit sold by Oricfan on Ebay. From what I understand it is based on Grant's design with a couple of corrections made so there should be no issues with compatibility.

Has anyone else on the group built one of his kits before?

Re: ZX80 3K Ram Pack memory

A little update on the RAM Pack seems to be in order here. Since the last episode all of the chips are now socketed and installed on the board as modified by Mr. Robson. The changes to the board consist of correcting the two crossed tracks that had required a little cutting and two jumpers installed...
