I built Zenith: a live local-first fixed viewport planetarium https://smorgasb.org/zenith-tech/ (https://news.ycombinator.com/item?id=48150097)

I added some Voltage Regulator stuff, and after trying to source components last night, some more transistor equivalents to Electronics Reference. It’s an app that should be of particular use to #retrocomputer enthusiasts. Please try the beta and lemme know. testflight.apple.com/join/DEfcHHBA

Trying a few interactive tools. My own electronics knowledge is rusty so it’s fun to relearn this stuff. (Yes we did have transistors in my day). testflight.apple.com/join/DEfcHHBA Electronics Reference on TestFlight

Half-way through Pogue’s definitive Apple book and it’s clear people really don’t know anything! As a species we stumble from one incident to another doing the best we can. There is no way someone earns billions while someone else gets minimum wage in this world, when so much is down to luck.

Might be useful to you - an electronics reference app with a growing number of interactive elements. Feedback very welcome. testflight.apple.com/join/DEfcHHBA

The Lisp-teaching app (LispLab) also got an update. apps.apple.com/us/app/lispl...

The entire economy is now built around software that is designed to generate stuff that looks like it could be right, surrounded by other software - and people - to test if it might be wrong and if so, try again. I’m not sure this is the best way.

Also a rather mad endeavor that tries to emulate S-100 computers and cards. In theory you can mix and match “cards” and use exotic hardware like the Dazzler and VDM-1. Or just CP/M and run Zork. Not perfect, but interesting. Https://grantmestrength.GitHub.io/S100

Virtual KIM got a 6502 assembler for each virtual machine: write code and then run it on a KIM or Apple 1. This is also a shareware app! apps.apple.com/us/app/virtu...

A few iOS apps got updated over the weekend. First up, Retro Computers got new computers, pictures and information. Check it out - it’s shareware! apps.apple.com/us/app/retro...

I’m at vcfpnw.org getting some pictures for the next update to Retro Computers app (a shareware encyclopedia of home computers). apps.apple.com/us/app/retro...

Fancy yourself as Sir Clive Sinclair? Put your ideas to the test. testflight.apple.com/join/pY3ZksZz

Test yoself! testflight.apple.com/join/pY3ZksZz Retro Computers FTW!

I updated the beta for Retro Computers (> 100 home computers now) and I bet you can’t read for more than 2 minutes without finding something I got wrong. Please tell me so I can fix it! testflight.apple.com/join/pY3ZksZz

You’re going to like this: My biggest retro-computing project yet! It’s an app that gathers information, specs, community, new peripherals.. everything I can think of. Here’s the public TestFlight beta. PLEASE let me know where I have made mistakes or omissions! testflight.apple.com/join/pY3ZksZz

Update to the (free) Opcodes app has added details of everyone’s favourite support chips (SID, VIC) and contemporary memory chips. Hopefully a useful resource when you’re retro-hacking. apps.apple.com/us/app/opcod...

What could I possibly add to an app that is already stuffed full of retro goodness? How about 25 more chips? Coming soon!

Saving so much money on tindie right now.

If you’re anything like me, well, sorry, but you also might have a collection of old computer books and magazines. Here’s a way to catalog them - it uses OCR and stuff so you can literally take a photo of your bookcase. Runs on iPhone, iPad and Mac. apps.apple.com/us/app/retro...

Virtual KIM also got an update. Improved 6502 lessons and a new ROM that might look familiar. apps.apple.com/us/app/virtu...

The DEC Opcodes app just got a nice update. Learn how to write low-level code on mini and mainframe computers; now with PDP-1 and PDP-8 programming tutorials. Especially useful if you have a PiDP-1 or PiDP-8! apps.apple.com/us/app/dec-o...

Update for “Opcodes” app is out! I fixed some missing 68000 instructions, improved the view on the iPad, and now you can paste in a string of hex digits to disassemble them in the scratchpad. apps.apple.com/us/app/opcod...

If you’re a 6502 fan, this free iOS app includes a bunch of 6502 data, an assembler and more. Just saying. apps.apple.com/us/app/opcod...

The April 1976 issue of BYTE magazine saw the first mention (and advertisement) for the KIM-1 single board computer from MOS, aka the best known 6502 dev system. The 6502 CPU made so many things possible - including Apple Computer.. Happy 50th Birthday, KIM-1!

The rumours are true: the new version of Opcodes has a “CPU Top Trumps” game. apps.apple.com/us/app/opcod...

A new Pocket Universe public beta is available. Some users report the sky tracking doesn't work. 😭 Please check to see if it works for you! testflight.apple.com/join/lQultGX3

What lunatic has two thumbs and added a top-trumps style game to an app about retro CPUs? testflight.apple.com/join/e3nSMedK If it the game beta isn’t on TestFlight now, it will be soon.

Learn Scheme - a version of classic programming language #Lisp - with free app (LispLab). On the Apple App Store now. apps.apple.com/us/app/lispl...

Gotta run code on real CPUs right? Latest batch from 8BitForce.com includes the 6800, 8060 and 8088. That’s a lot of 8s.

Thank you! This is awesome, the iPad version also works fine on my M series Mac.

My retro CPU app is now out. Lots of information on your favourite 8-bit and 16-bit processors. It’s all free too - so give it a look! Instruction sets, pin-outs, sample code and more! apps.apple.com/us/app/opcod...

Trying to help myself so thought I would share to see if it helps anyone else. Got #tinnitus? Maybe this will help. It’s on beta - your feedback very welcome. testflight.apple.com/join/HhYWwQt6

The modern version of those awesome pocket reference cards. @sdforg.bsky.social testflight.apple.com/join/nTcrH9mf

App update: Added 8088 and 65c02 opcodes and lowered minimum iOS requirement to 18. Wondering if this app is actually useful? What would make it useful-er? Or is it more of a comfort thing to have The Sacred Knowledge close to hand? Try it and let me know! testflight.apple.com/join/e3nSMedK

Retro computer enthusiasts: you might find this CPU opcode app useful. Please let me know of errors and omissions! On TestFlight for iOS now. testflight.apple.com/join/e3nSMedK Z80, 6502, 8080, 6800, 6809, 1820, 2652

I updated Trek 75 with a tutorial for all you young tribbles who don’t know how to play the classics. apps.apple.com/us/app/trek-...

I think in some instances a @bluescsi.com can emulate a scsi Ethernet adapter via the raspi wifi. As far as a guide for #globaltalk check out the one linked here. marchintosh.com/globaltalk.h... Maybe some of the folks who are actively using it can chime in here. They are awesome.

Lovely moon tonight. Jupiter is just beside it.

On this day in 1946, ENIAC - the first general-purpose electronic computer in the US was formally unveiled to the public. It filled an entire room, used 17,468 vacuum tubes, and consumed 150 kW of power. I didn’t quite finish my VR simulation in time for ENIAC day.

I’ve created an MCP Server that will help writing and debugging #6502 assembly by creating a virtual machine (based on VirtualKim). If you dabble in 6502 it might be useful. It works alongside Codex, Claude Code etc. github.com/GrantMeStren...
