Old Atari SF354 --> HxC Floppy Emulator

[Old Atari SF354 --> HxC Floppy Emulator]

Thanks Poobah - that's a great start and i'll see what i can do to get the rest of the chinon wiring.. I appreciate that

 

Quadrunner - that is what i was hoping to do but when i opened up i wasn't lucky enough to have a SF354 board with standard 34 pin setups.. i do want to do the A/B swap and keep the 'real' floppy inside my 1040 and mega ste, just need to get this floppy emulator working externally first, which will require some kind of 14 pin to 34 pin adapter i'll have to hack together...I appreciate you taking the time to write this up.. I may just tear open my external SF314 next and see if that has what i need..

Thanks Paranoid - unfortunately this is a very old mechanism with the 14 pin setup instead of a normal 34 pin floppy connector.

 

Poobah - yes, i searched, searched and searched.. google, atari-forums atariage .. found a few posts referring to it but the pics and links from those posts with the info needed no longer worked..

 

tried a bunch of 'poobah floppy' 'poobah sf354' poobah sf351 searches etc just now... no luck

[Old Atari SF354 --> HxC Floppy Emulator]

Hi Folks!

 

I need some help/advice..

 

I have an older SF354 that is in bad shape. No real desire to fix it since I just picked up a Mega STE and a 1040 ST each with nicely working internal floppies.. (I've always wanted the Mega STE and really enjoying having it now ).

 

I took apart my SF354 after receiving the HxC (SD Card version) and realized it's the really old type with the 14 pin connector..

 

I did a ton of searching on the web and was hoping to figure out how to wire up that 14 pin mechanism to the 34 pins on the HxC (if it's even possible). I have some IBM floppy cables I can use for hacking/testing purposes..

 

So questions are:

- does anyone have a wiring diagram?

- is there a solution I can just buy if I'm lazy to hook up the HxC straight to the atari via the standard DIN / external connections?

 

(I also have an UltraSatan which i'm enjoying, but was looking for some floppy emulation for my 2.5mb 520STm)

(Yes I eventually will look into the a/b floppy switches )

 

Thanks very much!

[Idiot of the year award - Atari 800 help please]

I think I deserve some kind of award for what I just did..

 

I unpacked my old Atari 8bits -- a couple of 800XLs, and old 800s I also had while growing up.

 

In the process of checking everything out, with the machine powered off, I plugged a Spy Hunter cartridge into the RIGHT cartridge slot of one of the (original) 800s..

 

The original Atari 800 was working but will no longer power on..

 

Any ideas what I may have damaged?

 

Thanks,

John
