Hello, cyberpals. I make @pushover.net and old Macintosh stuff and @deskto.ps and sometimes OpenBSD stuff for you and me.

man i am not good with these computers
Does anyone happen to know who owns rt\.fm now? Looks like it's just parked at a Hetzner IP but not hosting anything.

In case your DM250 ran OpenBSD too fast, I made armv7 able to boot from a softraid disk so you can have a fully encrypted eMMC root.

what are some smaller software projects or networks that need donations?

I posted a 68K Macintosh "game shell" on Github if anyone wanted to dabble in writing a vintage Mac sprite-based game.

github.com/EngineersNee...

Included, a beta of "Flappy Toaster" (a game-shell demonstrator I threw together).

I will be at Vintage Computer Festival Midwest this weekend with a table (B114) of Dolch stuff, because there are too many Macs there

For the first time in 7 years, I have booted the CPT Phoenix Jr. A couple hours of experimentation and investigation with a Greaseweazle last night finally allowed me to recover the only known copy of its software!

I saw this SCSIknife Multi used in @curiousmarc.bsky.social's video (youtu.be/85mLokY_oe0)

www.tindie.com/products/jur...

I like that the single form factor has all 3 connectors (50-pin, 2.5" portable, and DB-25) populated so it can be used on anything without having to buy separate devices.

I ported enough of NetBSD's armv7 MP code to OpenBSD to do a 'make -j4 build' on my DM250X.

It brings a full system compilation from ~5.1 days to ~3.5. Compiling LLVM is still multiple days :(

The only thing I needed to hear from the new Framework 13 Pro reviews is that after 5 years they still haven't fixed the wobbly screen hinge

Some scattered thoughts on AI

Case in point, I saw these today:

github.com/mplsllc/macs...
A modern web browser for Mac OS 9 with CSS, ES5 JavaScript, and TLS

redd.it/1tph8w3
A 3D printer monitoring app for System 7 with video

A year ago either would have sounded awesome but now I scroll past because I assume AI wrote it all
I have lost all enthusiasm for reading about new software projects, especially dealing with vintage computing. What would have sounded amazing a year or two ago and made me want to engage with the author, I now just assume was something AI spit out and feels hollow and boring so I skim past it.

Sorry for not posting for so long... I have been extremely busy working on my new project: The Enchanter (also called Modos Flow): a 300-ppi Eink portable monitor with 60Hz refresh rate and touch screen. It's fully open-source: gitlab.com/zephray/ench....

Let's look at this interesting CPU upgrade board for the Macintosh Plus and try and build it. 🛠️

Another Pomera DM250 special release: the DM250XYZ in a translucent purple color

Interesting that the keys aren't translucent like on the DM250X and DM250XY

My backup strategy is restic to rsync.net hourly/daily/weekly depending on the system, retaining a bunch of snapshots

Once a month, I manually run a script that fetches the latest backups from rsync.net to a portable disk, imports database dumps to a fresh mariadbd and runs some stored queries
Have at least THREE copies of your data: the live one on your computer, and at least two backups.

Use at least TWO different storage media, eg, your computer's drive and another drive. Ideally you'd use different *types* -- hard drive, network storage drive, tape/optical.

Dimming the screen for the screen saver on #PicoIDE was boring so I added flying toasters as an option. Sprites borrowed from the PicoPOST project
