Restoration "Apple II Clone"

Hi, we are getting an Apple II clone up and running.

( Excuse my language, I use a translator )

 

The Apple II Clone was in this state. It was collected many years ago, its destination was a recycling plant. With the help of some friends, we have gotten to it.

 Before putting it into

 

Before putting it into operation, we check all voltages.

The entire process has been carried out by friends. Without your help it would not have been possible.

For the cleaning process, we used "Alcohol isopropílico", also know as "isopropanol" .

I love seeing another system saved from recycling

Clones need love too. 

Well done Tulack. I hope it brings you much joy.

Comment on Apple II clones and the sockets seen in the photos

"Clones need love too."

 

Uncle Bernie concurs. I have one Taiwanese made clone, too. And guess what ... this clone never gave me any trouble, it runs, and runs, and runs ... unlike my Apple IIe (one of the RIFA caps in the power supply exploded, so now it has a PT-65B inside), and worse, NONE of my early Apple II originals works anymore, as they did use the lousy low profile IC sockets with the weak 'dual wipe' contact fingers, the same cr@ppy socket type found in the Apple-1. Not necessarily the same manufacturer. But these sockets long went the way of the Dinosaur, and for a reason. They never were very reliable.

 

The clone seen in this thread uses a much better, much more reliable type of IC socket which is still being sold today  - - - but these do have the feature / bug that their snail-like contact can grab the IC pin so strongly, that the 'snail' gets pulled out of the socket and is destroyed in the process. So when you see this type of sockets, you need to extract the ICs very carefully. I always try to pry the ICs  loose by putting a small screwdriver blade between the IC and the socket, and then use this as a lever, just a little bit, and then other side, and only when all pins have been moved, I apply the IC extractor tool.

I often use that extraction method as well.  You are entirely correct that while reliable, they are fragile in that way.  When building with them you also often have to be careful as many of the makers of that type of socket just press fit the metal into the plastic socket body and if you aren't careful you can inadvertently push a pin back out.  I ran into that with some (expensive and somewhat hard to find) 48 pin sockets when I was building Apple2Idiot cards which use an IDT 7132 dual ported SRAM which uses that huge package.  If you aren't careful when you put the sockets into the PCB you can loosen the pins. whch have to be carefully pushed back before soldering the socket into place.

Thanks for sharing all those

Thanks for sharing all those nice pictures! Isn't it lovely to see the nice board colour when the grime goes away?

You can use soap and water to wash - I then rinse in distilled water to remove any mineral residues from tap water. If you have compressed air, you can use it to dislodge the water from under the ICs, then you leave it to dry for a few days. 

Personally I use a dedicated fluid from Electrolube which is also great at removing oxidation but it's not stricly necessary.

 

Well done, it looks amazing!

 

10 ? "Hola Mundo" 

Does that mean that "?" replaces the "PRINT" command??

In Applesoft BASIC the ? is a shortcut for PRINT.  The tokenizer will replace it with the token for PRINT when it parses the line.

ROM

Hello from Ireland, I got the same one from Nederland couple years ago but with no ROM at all. It's anywhere a dump of the original ROM ? Thanks in advance

Pretty sure you can just use the Apple ROMs.

You can use the original

You can use the original Apple ROMs.  Most of those clones shipped with no ROMs and they were added after they arrived in the US (due to customs/copyright/etc).  A lot of dealers or mail order sellers here either left them empty and the user supplied their own EPROMs or they were often sold with copies of the Apple ROMs or with ROMs patched, often to allow lower case input or other minor things.  Those that did ship to the US with ROMs were mostly the early ones before Apple started complaining and they often were basically the Apple ROMs with a few patches like they would say "UNITRON" or "ORANGE" or whatever brand they were being sold under instead of APPLE ][.

 

Some software wouldn't run with the patched ROMs which is why a lot of people copied the Apple ROM images.

 

If you want the clone images I would bet someone has them.  I don't have a Unitron machine myself.  I have a Pineapple and a Micro ][ which have their own patched ROM, as do the Franklin ACE 1000 and ACE 1200 I have.
