Hello dear Apple (1 + 2) users.

I would also like to proudly present my finished Apple1 Clone to you. Due to the component procurement via Bernie, things went very quickly in the end.Everything works wonderfully too. I only have to do an endurance test with the RAMs when the device has warmed up for 1-2 hours.

I think the right keyboard is great too.Greetings from Germany.

Hi AppleMicha!

Glad to congratulate you on a successful build, Uncle Bernie's proven chip kits have proven to be excellent. They make the debugging process a mere formality - just plug it in and you're done! What do you think about the case?

I do not know yet...I will

I do not know yet...I will certainly not do anything on the Apple1 for several weeks, but you might just want to look at it anyway.

I am considering whether I (like so many) just screw it into a large wooden board.

Or, as many have made, a nice (old suitcase) suitcase solution.Then it is protected from dust, but you can simply "open" it quickly.

I did it this way, very convenient, transformers and board on one base. Not authentic, but practical!

the small PS2 keyboard adapter is definitely practical ... but don't you want to build an "authentic" Apple1 / Apple2 keyboard too?

For the YouTube channel and demonstrations I use the keyboard from Apple ][, if you yourself sit more convenient through the adapter.

Nice Apple 1

wau .. yes .. together with your real Apple II keyboard it looks very good.Personally, I think standard IC sockets on the Motherboad are optically better than precision sockets.Your ceramic PIA IC also looks nice. Is it a 6820 or 6821IC.?I still dream of a 6502 ceramic CPU.

Excellent job, I like it!Go

Excellent job, I like it!

Go "green" ! :-D :-D

 

I don't know the quality of that edge connector, it looks nice and robust, but I strongly suggest to always have a look to the edge connector before switching on the computer.

When there are no boards in it, due to ageing / heavy usage / damages / deformations some contact could accidentally touch his counterpart on the opposite side.

The most dangerous row is the 22-Z where +5V may get in contact with -12 (unregulated!), second in line is 21-Y where +12V unregulated may fry the 74154.

Both shorts cause instant damages.

 

It actually happened to a friend so trust me, it's not an urban legend... :-/

 

Regards,

Ciao!
