Re: Drive swap on STe without cutting pins/tracks

I also use GOTEK as internal drive. DnSEL signal for drive is only a D...

Re: Drive swap on STe without cutting pins/tracks

If the Gotek is installed as internal drive, and there is no external drive configured as drive 0, it has to be set at ID0. Also please notice the location of pin1 on Gotek. Everything is explained in my first post in this topic, please read it carefully. Gotek is no different than a regular FDD. Th...

Re: Drive swap on STe without cutting pins/tracks

The internal drive gets both D0 and D1, I assume thats so you can copy from Floppy A to Floppy B by swapping disks.. No, disk swapping in single drive machines is done completely by software, DS1 is never active there. According to the Shugart standard there are 4 drive select lines routed to all d...

Re: Drive swap on STe without cutting pins/tracks

Jumpers only route DS0 and DS1 signals to the external FDD port. By default, in models which have an internal FDD DS0 is not routed to the ext. FDD port at all. That's why I only use one of these jumpers in my STe and I also switch the jumpers on the internal FDD. So in first switch position I route...

First few bytes depend on a TOS version. TOS 2.06 synchronizes clock with IKBD, older TOSes doesn't do that (unless some software is loaded).

Re: Wanted : SF314 drive

DIN-5 also has 5V and 12V. DIN-7 (for ST) additionally has -12V. On the forum someone showed SF-314 with DIN-7F power connector - don't know if this was a common version or not, but I haven't seen another one like that.

Re: Wanted : SF314 drive

It is DIN-5F on the power supply. So basically, there is a DIN-5 socket on a cable, and plug on the chassis. It has 5V and 12V output, but 12V is not used in last models of FDD. You may use DIN-7 power supply from ATARI 520ST, it will work without any modification, and original plug will fit.

Re: Does anyone have an original SF314 disk drive With the square button ??

SF314 was the double side double density drive. You may use regular floppy drive set to drive 0, like in any ST (media change detection may not work). In STe and STf(m) you can attach only one external floppy. Reverse connecting the activity LED won't do any harm to anything, it just won't work unti...

USB charger may have not enough power to run a 5V only FDD, and if not the power adapter itself, also the tiny wire in the USB cable doesn't help.

Re: Exist any Intel x86 port of Atari TOS?

TOS was unique to Atari, but its user interface, GEM, did exist in a PC version (actually Atari have ported it from PC). TOS is a mix of CP/M and DOS. Initially Atari wanted to use GEM on CP/M 68k.
