Smartport Question & Solution

Hello all, 

I creates here a separate thread regarding Smartport behaviour. 

Smartport is not exaclty working the same between the IIGs, IIc & IIe

 

On the IIc & IIe via Smartport SP card, issuing PR #5 starts the smartport with the command 0x85 to init devices and start reading first boot device (id the lowest)

 

On the IIGS it is a bit different, at boot time it, it start checking the SELECT pin LOW and init device.

If he find not drive or no boot drive, then it start looking at C600 for boot disk

Unleashing the Legend: The Apple IIe and the Disk II!In this episode, we're diving into a true titan of early micro-computing: the legendary Disk II floppy disk system for the Apple II. Designed by the brilliant Steve Wozniak, the Disk II wasn't just another peripheral—it was a seismic shift in engineering ingenuity. Its streamlined, cost-effective design fundamentally unlocked the full potential of the Apple II, tearing down barriers that shackled game devs.

Single Step in Monitor

Hi all,

I'm not seeing it, but then again, I may be looking in the wrong place. Does the default monitor or the DOS 3.3. monitor do single step? If so, how? If not, what did folks do back when? Even the KIM-1 had single step, so, it must've been pretty common...

Thanks,

Will

What's the best Video solution for a Vintage Apple IIe in 2025

Continuing our series on using an Apple IIe in 2025, today we are getting video working. Do we use a vintage monitor to get that authentic CRT look? Or do we use a modern flat screen? Another option is to use a modern Apple II video card. Yes, we can even use HDMI! Watch on to see the options you can use to rock 1977 hardware in 2025 and onwards!

Help wanted testing softswitches

Hi folks, I'm fixing a few emulation bugs, and am hoping to find a volunteer to help verify behavior on real hardware.

Specifically, I'm looking for someone with:

  • an Apple //c or //c+
  • an Apple ][+

and the ability to run this disk image (i.e. with a BMOW floppy emulator, ADTPro, or similar).

This self-running disk contains:

MedFLy Apple II+ Clone

Hi All, I recently purchased a large collection of Apple II equipment from a retired IT administrator who had worked in a local K–12 school district. Among the items was a MedFly, which—based on what I can tell—is an Australian clone of the German Basis 108, itself a clone of the Apple II+. So, essentially, a double clone!

Apple IIe Disk Stuck on Write Protection

I'm trying to write some disks using adtpro and I keep getting a "This disk is write protected" error. I used the other drive and same issue, and I know that one works. I've gone in with a q tip and some isopropyl and cleaned the inside of the rail, but no luck 

I'm thinking it's a software issue

Floppy Emu Alternatives

I was looking for a floppy emu in general, but spending $150 on one doesn't sit well with. I do see some alternatives, like wDrive and Booti, but i want to know any others that are cheap. As long as they do the same thing the Floppy Emu does, it's fine
