JiffyDOS is now installed and working. 🙂

With a switch mounted, so i can change back to the Kernal ROM i had in the machine before, if i would need it in the future.

I also changed the LED from red to blue, and changed the capacitors, if you with keen eyes noticed that on the picture and remembered the picture from the previous post. 🙂

I did a simple speed comparison between an original C64, a C64 with JiffyDOS and when using a Final Cartridge III :

My test file uses 92 blocks on the disk.

Original C64 :
57 seconds.

With JiffyDOS :
9 seconds.

Final Cartridge III :
6.5 seconds.

As you can see, the Final cartridge III is the fastest one when only looking at loading times, so JiffDos is not really necessary if you use this type of cartridge and just loads games.
(If i did these tests correctly…. 🙂 )

If you Google JiffyDOS you can easily find an authorized sales channel for JiffyDOS.
I bought my firmware from one of those. (A Kernal ROM file)
(And i have an order confirmation email and an order ID to prove it if necessary. 🙂 )

It is also available as a chip-for-chip replacement ROM, so you just have to swap the old chip for the new one, for those of you that want the job done quickly. 🙂
Remember that you would have to buy one for your diskdrive too… 🙂
