I was never able to get that one to work with my A800, has anyone had any luck with it?

I made that one from Nir, and it works fine,

 

This is the one I bought. https://www.ebay.com/itm/PL2303HX-USB-to-TTL-RS232-COM-UART-Module-Serial-Cable-Adapter-for-Arduino/322619331980

I don't understand.... if you have a sio 2 pc that works... just boot with the sio2pc and create the disks yourself... the images are everywhere...

you can swap the boot drive # in ape, respeqt, or whatever....

 

You don't need pro-system or the 1050 switch mod to make disks, it's just super convenient... You can always sector copy from one drive to another. If your sio 2 pc can't get along with other sio devices it need to be re done...

New cable will be here tomorrow. I will be certain to connect the handshake wire, etc. and test before heatshrinking this one. It will be a good excuse to hunt up my Fluke 87.
Yes, the existing cable needs to be redone. Each wire and then the entirety was heatshrinked, so I decided to forego tearing into it and to start over. This next one will surely be better and cleaner.

Willing but quite far away. Standing by if no US floppy copier comes forward, just send a PM. 

Thank you very much, slx! I sincerely appreciate it! A couple of minutes ago I ordered another cable from Amazon that will be here tomorrow and I will rectify the issues I had using the homemade DIY2PC-USB with the 1050. From there I will be able to make he disks. 
 

I was going to wait and save a little $ and get the compact SIO plug version from Lotharek, along with a couple of other things, but will go this economy route for now.

When you are poking around the web sometime, head on over to www.retrobits.net  Check out Atari810.  It was the ancestor of AspeQt and RespeQt.  Of course, much has changed and been improved upon in the intervening years.

Thank you for the link! I will try that out in a little bit. Looks cool and makes me wish I had an 810.

 

It was a pain in the ass, but I got the outer heatshrinked off of my cable and connected the CTS wire. The shell around the USB connector was loose, so I popped it off. There was a loose wire at a solder joint. I fixed it and super glued the shell shut. I made a TBXL disk and it boots and all, so I’m a happy camper. SIO speeds are improved over the prior incarnation. This 1050 definitely needs to be made Happy, however. 
 

Edit: Retrobits has an article about 1200XL keyboards being wonky and a guide to repair them. I pulled out one of my 1200XLs two days ago and some of the keys do not work. This is quite helpful!

Here's my recent build:

(Note:  The hot glue is holding in some plastic brackets to hold in my board, not the board itself.  The case I found on Thingiverse didn't fit my board exactly, and there is something about the STL files I downloaded that print fine, but don't look good when I load them into Tinkercad to edit them. (I have been playing with Meshmixer to try to get something I can edit).

Here it is in the case and attached to the 400:

Seems to work fine so far...

I don't plan on daisy chaining it, so no need to order any diodes at this time. ;-)

Hi everybody, i've used for years the following home made circuit and works perfect, it's really cheap and easy to do:

https://retrogames.cl/sio2pc.html

Excuse if it is in spanish, but the scheme and the materials list is universal, and you can easily translate with your browser if you wish. It is a serial to SIO port converter; you can use an old PC with a DB9 serial port and Windows XP; i personally, use it with Windows 11, and the serial port is an USB 2 serial CH340 (driver install required). The main chip, is really easy to find:

MC1489 and LM1489 are fully compatible:

The software, is a freeware called "AspeQT":

https://sourceforge.net/projects/aspeqt/

You can emulate many disk drives using ATR or XFD images, plus, you can mount folders (with no subfolders) as disk images; plus, you can copy real disk to images and visce-versa.

My hardware, is a 65XE GS with 64K of RAM, i can play Yoomp!, His Dark Majesty, Bosconian, Break it, Arcadia, Dr. Mario, JrPacman, etc., many ports and ABBUC games, any game made for 64k machines, on floppy or executables.

I went into my storage container looking for a multimeter and found another 100 floppies. Today may be a good day after all.

Hey! Incredible, you can record so many games on those disks, Have you ever played His Dark Majesty? Its something easy but a good strategy game which requires a disk. As i understood, you require your atari floppy disk drive back working, or a working drive, i hope you can get one soon.

RespeQt is great. I always assumed RespeQt was just the newer branched off version of AspeQt which I've therefore assumed was no longer updated, etc. 

 

Whatever works for you is great. I've never used AspeQt myself. RespeQt is easy to use and works great with my SIO2PC USB adapter whenever I needed to use it.
