uIEC:
My uIEC has been working great, but I really needed a way to disconnect it fully without opening the case. My first thought was to put a SPST toggle switch inline to break the power. BZZT, no go. Next thought was to use the toggle switch to break the ATN line. BZZT again. For testing purposes I tried disconnecting both power and ATN, but there were still problems. All 4 data lines and power should be disconnected I decided. After some discussion with Vanessa, a 4066 seemed to fit the...

To do:
Add more device switches so both 1571 drives and the 1581 can be selected to any device number 8-11.
Add power switches for both 1571 drives and 1581 drive.
Build a RTC module.
Add a power/disconnect board to the uIEC so it may be completely disconnected by a toggle switch.
Build a modified Quickscan board and mount internally.
Mount a motherboard reset switch to the front of the case.
Mount an IEC (floppy) reset switch to the front of the case....

Just a small update. I had taken a little bit of a break to simply USE this computer, but I am not moving forward again. I am proceeding with installing a 1581 disk drive internally.

The picture below is misleading, it is more difficult than simply throwing a common PC floppy drive in a 5.25->3.25 adapter. A typical PC floppy drive will not work. An original 1581 drive is the wrong dimensions and has no standard faceplate. What was used in the end was a modified Chinon FZ-357A drive....

Welcome to my 128 Tower project blog! There has been a modest amount of interest in this project, so I figured a blog would be warranted. This is the first time I have used a blog, so don't expect it to be well written or with very good grammar

This project originally started back in 2008. If you ever used a Commodore 8bit computer with more than one accessory, you know how cumbersome it can be and how much desk space it can take. On top of this, if you start doing modifications...
