Microsoft ALDS disk image

Submitted by aofapple12 on September 8, 2021 - 6:11pm

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

Submitted by microstar on September 8, 2021 - 4:22pm

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?

Submitted by Heyme on September 4, 2021 - 1:30pm

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?

Submitted by Ronin47 on September 3, 2021 - 4:58am

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

Submitted by mkinn on August 30, 2021 - 11:29pm

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

Submitted by jnoxon on August 30, 2021 - 11:12am

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.

Apple //e no power when Disk ][ drives are attached

Submitted by ryandesign on August 24, 2021 - 9:05pm

Hello friends! I figure it's about time I created an account on this site given how long I've used Apple computers. 

I just took my non-enhanced Apple //e out of storage yesterday and spent several hours using it successfully. Today it would not power on (no beep, no LEDs). I isolated the problem to the Disk ][ drives: when both are disconnected from the Disk ][ controller card, the computer starts normally.
