Re: New member from Oregon, USA

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 fr...

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 ...

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, t...

Re: ZX81 ULA-in-a-CPLD

Whilst knowing nothing about the original problem I can concur with Mark re the ROM. I have a Hunter EPROM board fitted with 4x 2716 EPROMS and all kinds of weird stuff would happen if I used it in conjunction with the Sinclair ROM described above(three all behaved the same). One example would be th...

Re: How bad was the wobble on the zx81

I've heard a lot about the wobbling issue with the ZX81. how bad was it? did it really wipe out everything? It was very frustrating, I made a little metal bracket that clamped the Sinclair Rampack to the main case - using the original screw holes. Helped a lot.... :D Julia Hells teeth! I have a ton...

Re: Possible bug in ZX81x2 ROM ?

Slow down Zsolt I'm running out of EPROMS!! :lol: Sorry Moggy, here is a newer one . :lol: Zsolt Thanks for this Zsolt. I have a few maths routines which I will test this with. One example being the Collatz conjecture ,which the new ROM speeds up significantly and although in places it resorts to e...

Re: How bad was the wobble on the zx81

I often wondered why nobody built a bus extender with a socket for the zeddy side, a piece of flexible ribbon cable and then another socket. Instant isolation of most things. Certainly overly enthusiastic keyboard mashing anyway. They did. A few people offered such a cable I seem to recall and ther...

Re: How bad was the wobble on the zx81

The wobble ,speaking for myself, was only apparent with the Sinclair packs. I switched to the snug fit Memotech units and wobble was never a problem for me from then on likewise with the xpand. As for the Filesixty keyboard pictured above I still have this one which is made of hard plastic and frank...

Re: New member from Oregon, USA

Glad to see you've caught the bug! As for the printers, the 2040(known as Alphacom in the UK and sold by Tandy) is the one to persevere with. no need to cut down fax rolls as any 100mm till receipt thermal paper roll will do the job.(served me well for thirty years) If the paper is white then it is ...

I am using EEPROMs (or flash in ZxMore). So I can update my Zeddies also in winter, when the sun is on holidays (and cannot be used to erase EPROMs) :mrgreen:
