Apple II

I am sure this has been answered somewhere, but a preliminary search didn't turn up anything definitive.

I have a situation where I cannot write disks.  Disk reads are just fine.

For example, it goes through the motions to format (DOS 3.3 INIT HELLO) but nothing is written.

I have narrowed it down to the disk controller card.  Switching that out has solved the problem but what about the Disk II controller might be bad?

BBS:I've tried using programs like Megaterm 1.1 and ColorTerm 3.5, but I've had no luck as they don't seem to support the Uthernet II. I tried using Spectrum, but it didn't show in color like I thought it would, and when I typed a character on my Apple Extended Keyboard II, it would type the character twice.

Hey, I have owned a VidHD and used it in my Apple IIe and IIgs for a couple of years now, with a Samsung HDMI TV.

In preparation for expanding to a new retro space, I bought several Dell 2007fpb monitors as they support VGA, DVI and SVHS

I understand that HDMI and DVI are signal compatible, and that a simple HDMI to DVI adapter, or cable should get the HDMI from my VidHD to my DVI of my Dell screen.

Problem is, it does not work.

Hi

I bought a usb to mini din 8 pins cable to use Adtpro with an Apple II GS and transfer files to local disks (5.25 or 3.5). https://a.aliexpress.com/_EIzLyC4 

Note that I managed to test my Adtpro with someone's Apple II e (with db25 cable) from my Win PC 

The apple 2 Gs doesn't have any serial card so I plugged the cable in the modem port

running the process with IN#2 and ctrl A + 14B before transferring the data, nothing happens on the 2Gs

I tried the printer port but it's the same result

Am I missing something ?
