Two small Apple II cards on the blog...
#Hemi_DiskII: a Disk II controller replacement built around a CPLD, made with Wing Yeung. $36 assembled.
#GrapplerMinus_V2: the SoftSP DIY card, now just two chips.

I’ve wanted to build a launcher for #AppleII #Paddle Games for a long time. It’s almost ready! Check out our Idle Hands Micro Paddle, too.

KeroBurn beta 6 is out. My free Mac app for XGecu T48 / TL866II+ now has preset folders, and if one chip in a 4-chip run fails you just fix it and retry that one instead of starting over. github.com/kerokero5150/Kero…

KeroBurn beta 5 is out. My free Mac app for XGecu T48 / TL866II+ programmers now splits ROMs into HI/LO or 4-chip SIMM sets, tests 74/4000 logic chips, and updates the programmer's firmware without Windows. github.com/kerokero5150/Kero… #VintageMac #RetroComputing
🤖 Made with AI
Made a #Mac #app for the #XGecu #T48 so I can stop booting Windows to burn ROMs. #KeroBurn: presets, drag and drop, multi-chip runs for HI/LO and ROM SIMM sets, and a hex compare view. Free, open source, beta. #KerosMacMods Apple Silicon testers wanted 🙏 github.com/kerokero5150/kero…

New: Pin contact test on the #T48. #KeroBurn checks every leg before it writes and stops if one isn't touching. The log draws the socket so you can see which pin it is. minipro only had this for #TL866II+, ships its own patch for the T48.

Write a file at an address. Each file has an Offset… button: chip address, start in file, length, and "keep what's already on the chip". Put a few bytes of patched code in a small file, give it the address, tick Keep, and only that ...
New on the blog: Kero's SE WevMac, a Mac SE that runs in your browser. Load a BlueSCSI or Floppy Emu disk image, edit it, and download it again.

We have released a web-based Mac SE emulator built on #vMac. It supports loading .hda files, which the original vMac did not accept. making it easier for all #BlueSCSI users to utilize!

New on the Kero's Mac Mods site, under Tools: two browser editors for the SE ROM-inator. Draw your own Happy Mac face, or turn any recording into a startup sound, then flash it with SE ROM Flash Tool.

New blog post: SE ROM Flash Tool 1.1, and how it got here. From BMOW's Flash Tool 1.6 to a tool that can rewrite the Mac SE's own ROM code while it's running. And AppleTalk is back.

遅ればせながら、BlueSCSI Toolboxの使い方を日本語でまとめました。
SDカードを抜かずに、Macから直接ファイルを転送したり、CDチェンジャーでCDイメージを切り替えたり、ファームの更新もVintageMacのデスクトップ側から操作できます。

Grappler Minus 2.0 is in the works. The four 74LS chips are gone, replaced by a single PLD. The circuit already runs on real hardware and the new PCBs are on order.#AppleII #retrocomputing #GrapplerMinus #KerosMacMods

The Flash Tool for the SE ROM-inator is now complete. Since the configuration became slightly more complex than the original hardware, I consolidated the design into a PLD.

The flash tool is finally working properly. However, since the logic has become more complex, I plan to switch to a PLD. Also, as I intend to sell this as a kit, the configuration might change slightly…

I'm currently wrestling with the hardware side of the SE ROM-inator. It turns out the SE's BBU didn't support ROM writing, so I'm trying to generate a CE with additional circuitry… #KerosMacMods #ROMinator #Macintosh
Many people likely have a #SCSI card installed in their PCI-based Macs…perhaps you do, too? That’s why it would be handy to use a #BlueSCSI #DB25 with this adapter. Stay tuned! #KerosMacMods #PowerMac
I created an #SMC ROM SIMM adapter for the #T48 universal programmer. This will make development work a little easier.

A bug in OCLP 2.5 prevented the root patch from applying to my Mac Pro 6,1, ruining my morning; I cleared the system cache and reverted to version 2.4.1. An hour was wasted... 2.5.1 soon? but, thank you to the development team, as always.
