Questions about the A2Pico

Submitted by linuxha on December 19, 2025 - 10:17am

I have a A2Pico with SD Storage & USB Storage. I'm looking for ProDOS so I can boot a Frob (Apple II/Atari 2600 programming device).

Where can I find a SD image with ProDOS?

Once I have it how do I boot the Apple II with the SD card?

Eventaually I intend on getting a Fujinet so should I switch over to a different A2Pico image?

While I'm not stupid (don't ask for proof ;-) ), I haven't played with an Apple II in a long time so don't assume I know much.

Thanks

Apple IIe comp. Motherboard - Unknown keyboard rom

Submitted by huttich on December 17, 2025 - 11:03am

Hello everyone,

I would like to use my old IIe-compatible motherboard, which I used to run with an external II+ keyboard, in an IIe case.

The original IIe has a 24-pin keyboard ROM, but this motherboard has a 28-pin socket. What kind of EPROM is used there? I assume the content should be Keyboard-German-341-0151-A-2716.bin.I would be grateful for any information.

Best regards,

Need help with 2716 jumper pads on a language card

Submitted by mochatea396 on December 17, 2025 - 12:36am

Hello members,

id like to use a 2716 EPROM for the F8 autostart on a language card. There are 2 jumper pads marked 2716.  I presume the one by the rom should be jumped but what about the other? It would need to be cut if anything but I want to confirm what needs to be done here before I do anything. Thanks

FPGA expansion card for Apple IIe - Byte Hamr

Submitted by rrico on December 16, 2025 - 2:55pm

 

Hey folks, new here. I've been working on an FPGA-based expansion card for the IIe called Byte Hamr. It's built around a Lattice ECP5-85F, and the idea is that different gateware turns it into different peripherals—serial card, RAM expansion, whatever.

I know Carte Blanche exists, but it's a closed ecosystem. I wanted something fully open where anyone can write and share gateware.

cc65 users: ProDOSi, an API to ProDOS

Submitted by Harry Potter on December 16, 2025 - 9:09am

Hi!  For those out there who use cc65 to program the Apple2, I have a library online called ProDOSi.  It is an API to the Apple2's ProDOS that is much more efficient than cc65's standard file I/O functions in that they don't require a lot of extra processing and don't need to usr malloc() to allocate the buffers.  You can find it at c65 additions - Manage /util at SourceForge.net.  Try it out!  I also have a replacement for cc65's text I/O called A2SimpleIO.  It is at

Tiny mod

Submitted by Wayne on December 15, 2025 - 5:28pm

There’s been a couple of times when I was about to pull a card out of an Apple II and noticed that the power was still on. With the IIe it’s pretty obvious but while there is a power light on the IIgs, it just doesn’t stand out. A while back for a project I bought a batch of LEDs on wires with a resistor in line and the connections covered in shrink wrap.

I just soldered the wires to 5v and stuck the LED in a vent hole. It wasn’t the tightest fit so I added a tab of silicon. If it should somehow come loose, there’s no bare wire on it.

Help with battery bombed IIgs

Submitted by fritter7 on December 8, 2025 - 2:25pm

I think I've bitten off more than I can chew. :) So I got my first two retro machines at VCF Midwest in September, and the SE was super easy. Just needed to replace the battery holder, added a few mods - fun! But I also got a battery bombed IIgs that I'm definitely not experienced enough to figure out what's going on. I've attached a pic of the area that was bombed - it's been cleaned up a bit since then.

Rana EliteOne Drive repair

Submitted by dayoff on December 8, 2025 - 10:16am

Hello!  I was wondering if anyone was familiar with any sources of information on repairing Rana drives?  I have a Rana Systems EliteOne on me IIe that just powers up and spins continuously.  I'd like to get it going but was surprised to see some manuals out there, but not a lot of people digging into this model, unless I'm just poking around the wrong places..

 

Thanks!

Pete

Smartport disk emulators and daisy-chaining

Submitted by colinleroy on December 4, 2025 - 11:39am

Hi,

In the last weeks I wanted to add a smartport "hard disk" to my Apple IIc setup, and chose a SPIISD for that. First I had a problem with it: it is not seen when booting from the internal floppy drive. Basically it's because it boots too slow and missed the smartport RESET/ENABLE sequence that is used for device ID assignment.

I fixed that in software.

Submitted by Chris T on November 30, 2025 - 4:57pm

ProDOS: Why This Changed Everything for Apple II UsersJoin me in this ultimate guide to the Apple II's ProDOS. Why did it take Apple so long to replace AppleDOS, a DOS only suited to the simpler DiskII system. What did ProDOS finally bring to the legendary Apple II and why did it become indispensable to all Apple users within just a few months of its launch? I'll answer these questions and show you how to quickly become proficient with ProDOS on your Apple II.
