Press confirms zeddy doorstop confusion

:D I stumbled into a great article reviewing the best "little" computers of the 80s. Sinclair took 3 of the 10 spots. ;)

Here it is:

Re: Issue 1 vs Issue 2 ZX80 case

Hi MaFli,

It does look good! Did you get the file from Shapeways? I looked there but didn't see a way to download it. :?

Re: Proper voltage for ZX81 AC adapter

The PSU with the cord that you want to replace, I have an alternative idea. Instead buy a black table lamp switch (like this for example - ebay listing and use it to join the cable from the PSU with a new lead complete with plug suitable for the Zeddy ;) Plastic cases with no fixing screws are held...

Re: Does anyone have this brochure?

No worries guys. I'm the one that bought this item :-) It is currently in transit to the Netherlands. I have a bunch of ZX/QL machines here, but I never owned a ZX80 before. I will let you know what is in the package when it arrives. Watch this space... :-) *edit And according to the description it...

Re: Proper voltage for ZX81 AC adapter

@gozzo and @1024MAK thanks!! Your expert advice is always helpful! The real trick it seems now is to figure out how to open these things up. All I have are the 'wall wart' bricks like this: IMG_0781a.jpg IMG_0782a.jpg IMG_0783a.jpg They seem really brittle. With laptop cases it's common to find hidd...

Re: ZX80 Gerber files

Hi Mark, I just left a comment about your vacuum forming idea for the case. What a coincidence :-) Great idea btw. Hi again! This is good timing. :D I just got back from another class - this time on injection molding. It was cool to actually see and experience the difference in the manufacturing te...

Re: ZX80 Gerber files

I'm in the process of redrawing the schematics and PCB layout of the ZX80 in my CAD program. I know this has been done before and I have seen the great job that Grant Searle did, creating foils so you can build your own.

Re: Proper voltage for ZX81 AC adapter

Thanks Mark - getting the actual part numbers from the other thread was helpful. I've got an order to put in with Mouser so I'll pick up a couple. I have another question about power adapters :? - one of my "Sinclair" labeled power supplies makes a pretty loud buzzing noise. It's not the typical hig...
