Also I i'm trying to collect more informations as possible about this machine. Commodore 65 was intended as C64's successor. It will be launched on market in 1991 but original project was closed cause too expensive and lacking of funds. It was an 8-bit computer with a greater graphic capability respect of C64 (video chip was VIC-III instead of C64 VIC-II). More colours, more graphic modes, CPU with more Mhz (3.54 Mhz). A very nice integrated floppies reader (3 and 1/2) and an extended keyboard completed this little jewel. I think the only wrong thing was that this pc was too late with times... infact in 1991 there were already pure 16-bit machines. Ah, its software must be retrocompatible with C64 software: that was a really good thing. If anyone has material and information about this topic, please contact me :) Thanks

Dear Friends,

my board is quite ready to "come to life". I'm searching the last component (a Kyocera quartz 28.75 Mhz) and i have found a complete Commodore 65 power supply :)

Stay tuned......

Have a nice day, Carlo

Yes, but you'll need an electron microscope, a very steady hand and a very fine and durable razor =).


I know I've said this before, but MAN how I would love if someone made a C65 clone.

Speaking of electron microscopes, I know that a certain Jeri recently purchased one.  I bet she would be interested if anyone out there would donate their chips... :-)

looks like c65 stuff starts to grow on trees now days... i also would love a cheap c65 clone, if anyone can pull that one of, their in for a buck or two i think. the c64 is getting old and will fall part sometime in the future so a new c64/65 product would be nice...

Xenobiotical, why dont you head over at lemon64 forum with your c65, there you will meet other c65 owners...

Thanks Guys for your interest.

I tried. But nobody helped me in my project. Unfortunately I found a lot of difficulties not only in finding the  missing pieces to my tab incomplete but also who has a full Commodore 65  is always reluctant to talk about and share what they have. In fact I  hope to resurrect my card but I still need a Commodore 65 keyboard to  interact with the card and a suitable floppy 3 and 1 / 2 which  powered the C65 machine as it was designed. Maybe you could produce a clone C65  cheap !!!!!

All the best

Carlo

I have a fully wroking C65, just not a working keyboard, the traces are messed up on the ribbon cable.  A regular Commodore 1541II or 1581 power supply works fine with it too, you don't need a special one for it to work.  I have been pondering about parting with it though.  Any interest in it?

Hi Guys,

i'm near to turn on. I have only to place the correct ROM. ROM is the only missing chip on my board (even quartz is ok).

Let's see.... and hope :)

Thanks for following :)

Take care

Hi Guys,
 
finally i have all components for C65 board. Unfortunately it doesn't power on. Signals (seen with oscilloscope) are all ok... except for CSG 4510.. it seems dead. I think 4510 chip is broken. Let's see. If anyone has spare parts for Commodore 65, please, contact me.
 
Thanks, Carlo
