Need help identifying cables

I recently received a haul of some Apple hardware including lots of cables, SCSI devices, and two computers (thank you Peter!). In going through the cables, I've come across some cables that I can't identify. Please help if you are able.

 

One is a DB15 M/M cable that has pins 1 through 7, 9 through 11, and pin 13.  

The other is a DB15 M/M with pins 1 through 3, 5 through 6, 9 through 10, and pin 13.

IIe in PC tower

Replying to Julian

It’s a NEC CDROM. It’s connected to the SCSI card and will read CDs. I don’t know if there’s software to read other formats but it works with ProDOS CD. I chose it because I can also use the front controls to play music.

I used a standard Apple 1.4mb drive with daisy-chain board connected to a superdrive card. I’ve considered adding a second drive but have never gotten around to it.

The 3 extra slots aren’t connected to a card, they’re wired directly to the motherboard.

Apex OS for Apple II?

Does anyone have any .dsk images with the Apex operating system for Apple?  I've searched around unsuccessfully.   I've seen a few images for something called Apex II, but that doesn't seem to be the same thing, as it runs under ProDOS and was created ~1984.

I have an Applesauce, but apparently it can not write a .woz file to disk. Does anyone know of a device that can?

Asking for hint: annunciators and HGR

Hi everyone !

It is not the first time I read some quick phrase about Annunciators implying different behavior of HGR colors.

Are they talking about the 4 Annunciator lines in the joystick DIP socket, or something else?

 

Thank you all !

Julian

DRAM test EPROM for all Apple II (except IIgs maybe)

Recently one of my 'IWMless' beta testers ran into a problem with his Apple IIc and needed a memory test program. Since the machine would refuse to boot ("Check Disk Drive" error message), the best way is to remove the firmware ROM (always socketed) and plug in an EPROM with a memory test.

Can you build a IIGS slot based DVI video card for $10 (USD)?

Can you build a IIGS slot based DVI video card for $10 (USD)? Yes, it can be done.

Would you want to build a IIGS slot based DVI video card for $10 (USD)? Now, that's a more intersting and difficult question to answer. The dury is still out on that one. 

For all you sensationalists out there, note that this is the build price and not the sell price.

Trouble with Disk II Analog Card

Hello, first time poster here! I had a stash of Disk II Drives that I have been fixing up and am down to one more, but cannot figure out the issue. The Disk II Analog Card had a faulty 74LS125 which has been changed out, but it will still not read any disks. However, when I insert a different, known working analog card, it reads fine, so I know the head is okay. I have tested each resistor, transistor, diode, and capacitor but still cannot figure it out. I have also changed out each IC chip with working ones with no avail.

Can I fix my Macintosh LC475's Video, Recap It AND then Overclock it? High stakes!

Can I fix my Macintosh LC475's Video, Recap It AND then Overclock it? High stakes!My vintage Mac and LC475 has poor video and on top of this it's capacitors are ALL leaking, causing damage to the machine! So we need to get into this machine urgently, to get those caps replaced and then find a fix for its ailing video output! Oh, and for good measure, we'll "overclock" it from 25MHz to 40MHz!
