Description

The original Atari made XF551 was a single sided pcb with fragile traces which frequently caused issues with the SIO connections. This reimaged version of the XF551 disk drive electronic board is a much improved version from the original by providing a proper two sided board. I added some additional optional features like 2in1 BIOS selection, front facing DriveID, Reset button and a dual segment LED track display.

Requires a fully functional XF551 Drive to

salvage parts from.

This pcb version also is designed to need fewer parts from an original XF551 drive.

Still needs some parts from a fully functional XF551 Drive

Description

The main accessory/optional circuitry is already placed on the XF551 A and B main board and should be populated. These two smaller boards contain the actual display and control mechanics. Fitting them to the front sides of the top case is more of an art. If you are not skilled in fitting pcbs into tight places, you might want to find someone who is. This will require cutting of the XF551 top case to fit the pcbs. But if you are game enough these two pcbs will allow you to select which of two BIOS and which Drive ID using a front facing switch. You also get a reset button and a power on indication with dual LED track display. These two boards should also fit the SF551 build and be compatibe with the iF551 board as well.
