Got µIEC?

Just a little while a ago i ordered a µIEC (without daughterboard) at Jim Brain’s with the intention to use this a a mass storage device on one of my C64’s. The idea of having a SD card and the ability to install other cartridges was very appealing to me. At first i was looking into installing this into a 1530 datasette but as i don’t want to carry around with various devices and cables i decided to install this into my C64.

First i needed to have a drawing on how i will arrange the wires. So i made a little sketch up.

To start out i created a template and drilled some holes into a plastic ‘casing’. With a Dremel i drilled holes and started beveling the holes to fit the screws. Using two bolts are holding the screws to the plastic plate.


To prevent the contact of the metal bolts to directly contact the µIEC PCB four paper-like rings are stacked on top of the bolts.


One of the paperish rings needs to be cut a little for a snug fit. Here is the bottom view of the construction:


On the top of the µIEC card i also added a plexi-glass plate to the stack.


Due to the height of the transistor i also drilled a hole into the top plate.


Buffing up and cleaning (using ‘pure’ alcohol) the plexi-glass first and the hot glue gun helped me fixating the construction to the memory expansion bracket.


Here you can see that the glue was spread out really wel.


After measuring multiple times this the chosen position. This was the most time consuming job.


Here you can see the wires as i soldered them on the back-side of the C64 PCB to the header of the µIEC.

Bottom side of the C64 main PCB. On the left side the µIEC wires and on the right side the audio/video modification wires.


Down here you can seen the same µIEC wiring loom to the µIEC PCB.


Cutting and filing the plastics away left me with a gap to insert a SD card.


Maybe i need to file a little away on the left side for more symmetrical esthetics.


Does it work? Eureka! The LEDs blink… so far so good.


The already installed JiffyDOS helped me to see the µIEC as the default drive and requesting a directory output resulted into this:



Also writing Prince of Persia directly from SD to EasyFlash worked (as long as your turn off the EF fast disk loader). Please note the two little black buttons for .D64 file swapping (using the AUTOSWAP.LST feature).
