Replacing the battery in an Apple IIGS

Submitted by Austin_iigs on June 9, 2024 - 1:43am

So I keep on seeing guides and warnings stating that I should replace the battery on my IIGS. However, I am often seeing conflicting guides, some saying to use battery holders, some saying to solder them on, some saying to clip them on. Some say to use 3 AAA batteries, and others say to use the Tadiran TL-5101/S 1/2 AA battery.  What do you guys think?

MG ROM++ for the Apple II/II+

Submitted by jeffmazur on June 8, 2024 - 1:54pm

First there was the ROM eX, then the ROM 4X and ROM 5X. All great improvements to the standard Apple System ROMs.

 

Now we have a version for the Apple II/II+ with ROMX+ !! Boot menu, coldboot, mini assembler and much more. See current status at theRomExchange.

What exactly is a Smartport please!

Submitted by Thlorian on June 8, 2024 - 12:34pm

Hello all - sorry for the noob question but I never understood what a smartport was/is for the Apple II computer line?  Is it a special hard drive technology that can be used on Apples?  Something else?  Tried searching online and found nothing -  thanks for any layman's terms explanations on this please!

ITT 2020 specific softwares

Submitted by Ben_Aveline on June 6, 2024 - 4:30am

Hello,

A few month ago I bought a nice ITT 2020 for cheap. It wasn't working. I cleaned the rom's leg (very corroded) and checked the whole ram (had to replace 6 bad chips).

Now it's back to life ! (except for the speaker, I still have to figure it out)

I managed to successfuly run a couple apple 2 softwares from a floppyEmu, but some other just freeze the computer or run but with graphic glitches.

I know there's been a few specific sofwares for the ITT 2020 but I can't manage to find a source for them, either as cassette dump or disk dump.

Apple IIGS Monitor for sale?

Submitted by Austin_iigs on June 5, 2024 - 7:44pm

It's super hard to find a working AppleColor RGB Monitor Model 6014 online for purchase, so I was wondering if anyone here would be willing to sell me their working monitor? Please don't tell me to get a VGA/HDMI convertor.

Apple II DISK Emulator using STM32

Submitted by VIBR on June 2, 2024 - 3:02pm

Hello, 

I know there are a lot of project available using SD or emulating disk drive. 

I am trying to make a new one available to the community, stable and cheap. 

I have started a new project to emulate the SDISK II using a STM32 bluepill and a SDCard. 

Once it is fuly working I will add a 0.96 screen, 3 buttons and make a dedicated PCB everything for less that 10$.

 

I am almost done with the prototype, but I need to debug a bit what the Apple II is getting from the stm32.
