Apple II disk card as a Smartport

Submitted by coopzone on January 29, 2026 - 12:06pm

I have an apple iie with a disk II card. I found some software for a A2PICO card, I normally use this card for z80 card emulation and it works very well.

 

I installed the software, but can't seem to get the Disk II card to work as an Smartcard.

 

Anyone managed this? If so how!

Circuit Diagram for an Apple iic (revision with 4xram ic's and a expansion header)

Submitted by coopzone on January 26, 2026 - 6:58am

Hello,

 

I recently got an apple iic computer. It worked fine for about a week, then degarded with all sorts of random issues until it eventually stopped working. Just a screen full of random characters.

 

I figured it may be a RAM Issue so started to look for the circuit to help debug the issue. I can find iic cirtuits with the 16 chip ram setup but not one for the 4 chip ram setup.

 

Does anyone have it? or know where I can download it?

Another Apple II rev.0 replica and an old clone

Submitted by SQ9PXB on January 25, 2026 - 10:35am

Hello,

Some time ago, I received a Polish Apple II clone PCB (it was called Lidia) for repair – it's the gray PCB without soldermask. It was manufactured in Poland in 1984. I decided to build myself a modern Apple II rev. 0 clone using available Gerber files. One is mounted in the original Apple II Plus case, the other in a 3D-printed case. The power supplies are modified Dell ATX boards. It also includes a language card, an 80-column card, and a Disk II card. Keyboard's are a Datanetics replica with blank MX keycaps. The letters are laser-engraved.

Help for connecting a 7" LCD to A2e

Submitted by JulGiul on January 18, 2026 - 10:34am

Hi everyone!

I just found an unused 7" color LCD, 800x480 with an LVDS 20 pin iterface (and touch screen).

It would be nice to use it on my A2e :-)

I suppose this is almost out of topic,  but every hont is well accepted!

I found 2 small driver cards with AV-composite input on AliExpress,  but then I have to choose the firmware, and here I get stuck,  since I have no knowledge about LCDs.

 

My LCD is an Ampire am-800480-rs-tmqw-ta2h 

3-3.6V , 2W,  20 pin LVDS

The almost correct specs I found are here:

Apple IIGS RAM Failure Diagnostics

Submitted by techconspiracy on January 12, 2026 - 10:27pm

I recently acquired an Apple IIGS.  When turning the computer on, the screen fills with the "@" symbol for about half a second (which I believe is normal), then shows the following corrupted display:

Introducing BurgerDisk, a daisy-chainable Smartport hard drive

Submitted by colinleroy on January 12, 2026 - 3:40pm

BurgerDisk is a Smartport hard drive for the Apple II. Its main unique feature is that it is daisy-chainable.

As all Smartport SD-based hard drives, it's more adapted to the non-slotted Apple II, like the //c and IIgs.

 

Here are a couple pictures of the finished device:

ImageWriter/Super Serial Troubleshooting

Submitted by Anonymoose on January 5, 2026 - 11:12am

Hello,

Seems I've run into a slight issue that I'm also curious about.

 

My ImageWriter DIPs are set to the defaults (11101011 0010) and so are my Super Serial DIPS (terminal mode, 0001011 1001100). However, in AppleWriter 2.1 when printing with the defacto 9600,8,N,1 setting, nothing is printed. It's only when I set DIP 5 on the printer to zero (ignores 8th data bit) that it prints correctly.

 

Not that this is a serious issue, I'm just curious if this is the correct setup and why it's happening. I'd like to learn about parity and whatnot :)
