!!!Percom Service

Tool to configure Percom Block Drives. This Tool can be used to test Disk integrity and to format all kind of different Disk Formats available for Atari Disk Drives.


{image:percom.png}

Needs ACTION! Runtime package to compile a standalone Version. Disk with Source and compiled Version attached.

I wrote this Tool to configure the HDI 3 1/2" Disk drive designed by Erhard Pütz (aka FloppyDoc)

2008-01-13 disabled break key, custom error procedure, updated copyright

!! How to use


|| Key	||  Description  ||
| 1 - 4 | Read Percom Block from D1: - D4: and update display  |
| T	  | change number of Tracks per Disc  |
| S	  | change number of Sectors per Track  |
| A	  | change modulation (FM or MFM)  |
| R	  | change stepping rate  |
| D	  | toggle doublesided <-> singlesides  |
| B	  | change Bytes per Sectors (normally 128 or 256)  |
| V	  | change Drive active Flag / HD flag |
| CTRL+F | Format selected Disk in configured Format (CAUTION!!!)  |
| CTRL+T | Read and Test all Sectors in configured Format, printing Status for each Sector |
| CTRL+S | configure Drive for Atari Single Density, single sided (SS/SD)  |
| CTRL+M | configure Drive for Atari Medium Density, single sided (SS/MD), 1050 Format  |
| CTRL+D | configure Drive for Atari Double Density, single sided (SS/DD)  |
| CTRL+H | configure Drive for Atari High Density, single sided (SS/HD)  |
| CTRL+Z | configure Drive for Atari Single Density, double sided (DS/SD)  |
| CTRL+Y | configure Drive for Atari Medium Density, double sided (DS/MD), 1050 Format  |
| CTRL+X | configure Drive for Atari Double Density, double sided (DS/DD)  |
| CTRL+V | configure Drive for Atari High Density, double sided (DS/HD)  |
