The beast grows. My #68k computer is getting closer to the finish line. Chewed through a lot this weekend!
Adjusted common ROM address lines, they were going over the chips and it bothered me. Plus, I'll probably be bouncing those in and out for a while until I venture to programming via a boot loader.
Wired up the many buffered address lines. I did a continuity check last night and it looks good so far. :blobsweat:
Finished the control line buffer and distributed the outputs. I used a big fat purple wire for /DTACK out of respect (or disrespect depending on whom you ask) :blobcatangel:
Finished the /IACK decoder
Wired up the GAL inputs and some of the outputs
New TODOs queued up:
Finish connecting the 68681 serial chips
Finish placing decoupling caps
Replace 7404 with open-drain 7405 variant to work properly with the /RESET line
Hey folks, if you like retro pixel art arcade adventures, with casts of extremely LGBTQ inclusive characters, and dancing skeletons who can see through time - you might like my in-development game, Quantum Witch!
I'd love you forever* if you followed @QuantumWitch where I post updates, art, and music from it.
This is a hard post to write, mostly because I am needing to balance being straight to the point, while providing enough context on a very complex subject.
FujiNet has grown into a larger project, with an increasing number of platforms being brought up. This project comprises not only the firmware that runs on #ESP32 hardware itself, but also the configuration program, and various application libraries and programs.
While I have a hand in all of these things, I can't have my hands in every bit of it, all at once, so I am asking for people in each respective #retrocomputing community to step up; help maintain their respective ports. I will take the time to teach whatever is needed.
We need people who can help with: Adding unit testing to both firmware and applications, maintaining CONFIG for each platform (#Atari8bit, #Apple2, #ColecoAdam, #Commodore, #CoCo, etc.), making sure that as we change the code things still work. (cont)
So Windows 2000 has this wild feature where you can just load arbitrary web content into the system management console, and I absolutely love the innocence of the time #retrocomputing
It's taken 6 months, but my latest labour of love is finally complete! You can now explore fully documented and annotated source code for Elite on the #NES, reconstructed by hand from a disassembly of the original ROM. Please enjoy!
another obscure #Apple2#AppleII#retrogaming#retrocomputing inquiry—ring any bells for anyone? I couldn’t turn anything up under this title for the Apple II, just legit games on other platforms. I strongly suspect a homebrew gag game, maybe even circulated among a small group of people…
My visit to the Ctrl+Alt Museum retrocomputing museum in Pavia, Italy, blew my mind. Why? The hundreds of photos I took speak for themselves, go see them now.
Opened a year and a half ago, the museum is a new and little known geeky gem packed with all sorts of vintage computing hardware and stuff. It's run by a non profit group of passionate collectors, enthusiasts, and makers who also do outreach and education activities.
More Ron Swanson than Elon Musk, Altair inventor Ed Roberts created the PC industry. Then, at the height of his wealth and influence, decided to walk away.
Oh I love this! The website for https://software.inc/ (a company by the folks that made the Shortcuts app that Apple acquired and baked into iOS) launches Mac OS 8.0 in an emulator and the content of the site is a classic Mac OS application. #VintageMac#RetroComputing /via @daringfireball
Sad #retrocomputing news if you are an OS/2 fan - it looks like the Hobbes archive is finally sunsetting. https://hobbes.nmsu.edu/
OS/2 isn't my thing, but this site has been an indispensable resource when I've tried it. Hopefully it will be archived somewhere.
This is a weird one, because it's one of the versions that didn't really see wide release in the first place, and is one of several false starts that ultimately led to OS/2.
Dear fellow #retrocomputing folks, does anyone have any information about this computer? We have one and it appears to work, prompts for a system disk. However we have no manuals, or system disk images. Any info would be really appreciated. It's a Micronix 80HD from a company based in London which appears to have since vanished.
