Not yet, even though it’s EOL I imagine they will still be in stock for a while, but this will make getting chips for all the kits a bit harder might make the prices go up on hobbyist projects in a few years.

Apple IIgs Black Screen
by James 19 Apr '24

19 Apr '24

Hi, I have an Apple IIgs and when I boot it I hear a beep shortly followed by another beep. The screen remains black. I've tried a second known working Apple monitor to the same result. I've tried it with both floppy drives attached and not attached. I don't have any disks but was assuming I would at least see a complaint on the screen about missing startup disk. I don't see anything. Does anyone know what my issue is or can you recommend a good Apple II troubleshooting site? Working on Apples isn't something I have much experience with.

Fun fact: you can hook the IIgs' monitor up to a lot of arcade boards as a display, though sometimes you might need to change from the default sync polarity. I used one to test my Defender boardsets back when I still had my IIgs, and it worked like a charm. There are also some Dell LCD monitors that support unusual features for LCDs (sync-on-green, interlaced video) though I'm not sure if they'd do 15 KHz. I no longer have a IIgs to test with, but I have heard very good things about the P1914's compatibility with a lot of things, and they're definitely very cheap on eBay these days, and worth keeping around for a lot of vintage things (a lot of old Macs also do sync-on-green, some of them like the IIci *only* do it, and a monitor that handles it correctly is essential if you don't want everything looking very green). If you're using a VGA converter, be cautious; the monitor sense signal lines function a little differently than they do on the standard Macintosh DA-15 video connector, and cheap ones can often short something to ground which prevents startup and may not be great for the machine in the long term. If you happen upon a Griffin MacPnP adapter, they're really the best of the bunch (and if you don't have one, let me know, I bought about a dozen of them a while back when someone was selling bucketsful on eBay for $4 each). - Dave
