Apple II with video and (probably) RAM issues

Hello,
I’d like to ask you for help with my Apple ][ board: As you can see [here](https://imgur.com/a/ocoGj2W) (the upper one is without the ROMs, the lower with them), the board has some issues with the video output and start up process.

Microsoft ALDS disk image

Hello all,

 

I am looking for a copy of Microsoft's ALDS (Assembly Language Development System) for the Apple with CP/M.

 

The usual suspects (Asimov, etc) have not yielded anything.

 

Thanks,

 

Armando

IIe RAM test results question

If the result of the built-in RAM test is 00000100, does this mean the chip at location "11" has been identified as the bad one?

Apple II+ HDMI converter - what works?

I have been struggling with what i thought was a colour killer issue as my text is always blue when using one of those amazon AV2HDMI adapters.  I finally lugged the apple up to an old LCD flatscreen and it works fine, but not very pratical for working on the desk.  with the adapter to a monitor i have to fiddle with the cable for a while before i get a clear picture (usually get almost jailbars over the image.  Color does not work at all, blue text/graphics on black or blue background..

Anything on the market that is known to work?  RFI Motherboard..

SELTRON DD40 External 5.25" Floppy Disk Drive - Anyone familiar?

I recently acquired a SELTRON DD40 External 5.25" Floppy Disk Drive, supposedly for Apple II series machines, however there seems to be a dearth of information around this item when I search for it.

I was wondering if anybody is familiar with these drives and has any information about them?

TIA

ROM 3 GS won't save Control panel settings, but keeps Time

New 3.6 VDC Lithium battery, + side towards the back of the machine, keeps time perfectly, but won't save Baud rate or Mouse tracking speed.

I'm pressing Return after changes to save them. Same for CDA's.  Nothing in the owner's manual about this.

Apple A9M0107 5.25" Disk Repair

I received an A9M0107 5.25" (1986 Unidisk) floppy drive with a IIgs I bought recently. When attached to the computer, the LED flashes briefly a few times at power-up, but otherwise it shows no signs of life. There's no motor movement, and GS/OS doesn't show it in the Finder. I know the Smartport interface is fine, because I'm able to read/write disks using a different drive.
