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 feel to be worth my time and effort.

And I'm still working (at least mentally) on my vacuum-formed ZX80 case project.

I truly enjoy the challenge. Plus, I'm pretty stubborn.

Now it's time to go see if the changes I made in my slicing software will do the trick. And I promise not to insist you change your name to Betty. That just ain't right, as we say down here.

The 3k ram pack I have to say is a thing of rare beauty and please keep at it with the printer, Mike as I know there are quite a few interested folk this side of the water with belt-less printers and the ZX80 case is certainly of interest not just for making an old one look better but also to house the replica board projects that exist. :D

Best Regards

Betty. Moggy.

Just a bit of an update on where I am.
(Some of this is in my Composite mod thread)

I made a basic (just 1 transistor and 1 resistor) composite mod and at a basic level, it works!
I cut back the ribbon cable a tad and now all my keys are working.
The 16k RAM pack isn't working. When I plug it in, the TS1000 won't start. I'll look at that later. Could be lots of things. I am probably going to add 16k internal to this guy anyway, but might want to get it working with my ZX-81.

I successfully loaded 2 games!!!
1K Chess and a 1K breakout game.
I tried loading them from my laptop directly with WinTZX, but it didn't work. So then I used WinTZX to convert it to WAV and then playing them (using VideoLAN.. I don't have another media player installed other than Windows Media Player apparently).
I was able to get both to load!!!

When playing them, I had to adjust the vertical hold to keep the screen from rolling. Not sure if the games POP into 50Hz mode or if my monitor just didn't like whatever mode they are in. Also, they do have some bending at spots. I can't really read the top line on the breakout game (where the score is) and with 1k Chess, there is a bend right at the center of the screen. Again, could be the monitor, could be the screen mode, could be a 50hz/60hz thing.
Still playable, but noticeable.
If I just go into basic and fill the screen with text, it is all fine. No bending anywhere.
I can't get it to display on my LCD screens yet (probably will have to wait for a CX8-CCB for that) so not sure.
I have some other composite devices I can try it on as well. (Some more CRTs)

All in all, pretty happy with the success so far.
I have most (but not all) of the parts for a TZXDuino, so that will be on my list when my tiny amps show up. (And I have to see if I have a slower SD card around somewhere...)

I'm considering a TRACO to replace the 7805 voltage regulator. Not sure if I need to do that.

I am also probably going to use the channel 3/4 switch to change from 50hz/60hz default.

My ZX81 I haven't opened yet. I know it needs a new power jack, so I will need to order that. (As it is the same jack as the mic/ear, I might order several. Just in case.) It will definitely need a CX8-CCB or new ULA or something, as when I did test it and get it to display on the TV, the picture was much darker than the TS1000. So I am guessing it has an older ULA with no back porch.
When I get it working, I will try the 16k pack there. Let me know if I need to open that thing to fix it. (I can do basic soldering and replacing caps. Troubleshooting beyond that level is something I am working on still. ;-)

Anyway, so far so good. (I think)

Top marks on everything done so far. :D

But please replace the bloody regulator for the Traco one as you will remove 99.999999 (old ROM value) of the heat from the beasty which apart from being most desirable will help your newly trimmed keyboard ribbons stay healthy as the material they are made from tends to crack when exposed to many heat up cool down cycles.

Again great work.
