Crucible is a recently developed app for MacOS that allows users to program 2MB SMC ROM SIMMs. The app was developed by Satanic Mac Club and One Geek Army, with most of the programming handled by One Geek Army. One Geek Army is known for developing DiskJockey, a popular disk image editor. Beta Version 2.0 Released Version 2.0 introduces new Split and Join modes, making the app useful beyond just SMC ROM SIMMs and enabling it to stand alone as…
I reverse engineered the Booster30-L33 from Interware and redesigned this card. It is compatible with ColorClassic (first revision) and LC II. Unfortunately, it is not compatible with LC (first revision). *In my experiments, I was able to install the LCII ROM on the LC and operate it normally, and use all the functions, but unfortunately it did not boot with this card. I need to analyze the GAL a little more carefully, but at this point I need the help of a…
I designed a type of RAM card to be used as a daughter board for the AIIE 80COL card. Many people may like the 80COL card, but I never used it and had a lot of it in my drawer. *In fact, 80COL is also supported in AII VGA projects, so there is no need to use the 80COL card alone. For now, it will not be open sourced and will be sold in my store. It will probably be…
We release A][ VGA MINI card. This is a forked project originally drafted by Mark Aikens and our project page can be found here. For this project, we know that various vendors design PCBs used Raspberry Pi Pico (RP2040) and make cards that function the same way, but for our card we aimed to design something that I would want myself… Our AII VGA MINI cards have 2 colors There are Purple and Black colors, but only the Black one…
Our open source project “Grappler Minus” has been completed. I was able to check the latest PCB, and new ROM revision V6a so I made a new post. The difference with Grappler Plus is that the printer interface function is removed. As a result, SPIISD can now be used on Apple IIplus, which was previously unavailable due to timing issues. In the new PCB version, all multilayer ceramic capacitors have been changed to dip type to make it easier to…
SP][SD DIY kit has been released This is an open source project hardware and anyone can build it for free (cc by-nc-sa 4.0). It was hoped that this would be made into a kit for people who have difficulty making PCBs.The Bare PCB was already on sale, but now started selling a kit that includes all the parts. *Ribbon cables are sold separately and can be purchased on Amazon or eBay.

Do you remember the SmartportSD that Katherine Stark created about two years ago? It is based on SmartPortCFA programmed by Robert Justice and ported to Arduino hardware by Andrea Ottaviani. Unfortunately Katherine has left Facebook, but I’ll be posting on her behalf. https://gitlab.com/nyankat/smartportsd I tried to miniaturize this device. The program was designed for Arduino Nano, but I found that it works well on the same chip, UNO and Pro Mini. So I ported this to Pro Mini. Read my…
