Apple II

Disk ][ does not boot

Hello all,

 

I have a Disk ][ drive that I can read/write  to (for example, using Locksmith to adjust the speed) when used as drive 2. But I cannot boot off of it; the disk just spins and the light remains on when I use it as drive 1.

 

Basic troubleshooting: the controller is fine, as I can swap the drives and drive 2 will boot. The cable *should* be ok as I can read and write to the drive when adjusting the speed. Drive was working (booting) when I last powered it up some years ago...

 

Is this a common issue? if so, what are the possible causes?

Looking for a couple "real" Language Cards

I have a couple of original II's (well one is a Taiwan clone of a II) that do not have Language cards in them.

I have tried a couple of the Saturn clone cards in them, but they do not work right... They may sometimes pass diagnostics, other times they don't. Neither works with Skyfox.

Does anyone have a couple of old spare Language cards they want to get rid of? They don't even need to be working- I can fix them.eBay auctions at nearly $100 "untested" with obviously missing chips seems a little steep.

Apple II disk card as a Smartport

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)

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

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

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

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

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:
