The same thing on a friends XL machine, with 2 x 27C256 eproms piggy backed. Initially thought cause fail the selector switch, but finally the eproms was bad. Of course I will replace with one 27C512 for the 4 OS's.

@flashjazzcat I can confirm cause placing the Lothar's version of Ultimate 1MB in 800XL with my way, the upper lid close perfect! Side day by day becomes more interesting. Ok, I make an open proposal to all from here. Taratarataraaa... If Sebastian support this, how will see the idea for an internal version of Side especially for Ultimate 1MB XL owners? A version without the SDX and real time clock. Only the main circuit in a form which could placed inside the computer directly to the cartridge slot with no solder points . In upper side of pcb there will be one cartridge connector free to place any other cart on the fly. Of course Sebastian must modify his firmware code as to allows to disable the Side. Maybe within Ultimate setup menu??

Yesterday a friend of mine gave me the new (from Lothar) "Ultimate 1MB", plus a "stereo final" upgrade to install on his 800XL. Finally I was able to place it, near the initially position as on first batch from Sebastian. To avoid the bunch and also to look better, I cut and remake the ribbon cables to optimum lengths. Also placing in this position the pcb, battery socket on bottom used as a second foot for better support. Because I have make this upgrade in my 2 Atari 800 and 600 XL, I will let you know cause the Lothar edition, is impossible to fit on this place as is in stock form! I mean with standard IDC connectors on ic sockets. Maybe someone has a better luck using angled ones. I attach some pictures above without comments. Please take a look...

Hi Marius. Yes, but what is the problem with the list?

Thanks both for your answers. I thought cause this thing operates according the logic of 1050 drive, but anyway I can live also as is! I can choose another drive as D2 etc, and all work good.

Hmm.. Roy we say the same thing. Maybe with my bad English not formulate it well! Ok please set your sio2sd as ID 2, Atari 1050 as ID1, and connect together on your Atari. After place a game on each one and power on your Atari. What you see? Normally only the 1050 must be load the game. In mine condition I have a purple screen with a boot error. This will never happen when I connect two 1050 together with a different ID! Am I wrong?

Hello. I am in a strange situation. Can anyone knows for what purpose is the device ID on SIO2SD? I mean the option on the configuration menu who change between 0-1-2-3. In my setup I have one 1050 as device "0", plus a sio2sd as device "1". If I place from one floppy on D1 in each device, then with command DIR from Sparta Dos X all devices run, and kaboom. Why all devices run simultaneously since they have different ID? The same also with my second 1050 or another sio2sd. Is a firmware issue of SIO2SD? The thing look to work correctly only if I use the second floppy D2 and empty the D1 on SIO2SD. Have anyone try this?
