Byte Cellar

Indeed, it is a DualUp -- the best display I have ever owned. I love it so very much, I planned to get a spare for when it dies, before they EOL'ed it. (I assumed it would not last long, as there can't be widespread appeal for such a display.) I missed that chance - but after months of setting eBay alerts, I found a local teacher that had a used one with just 400 hours on it (I have 17,000 hours on mine), and I bought it ($50 above retail price) and have it cleaned and waiting in a cloth sleeve for its time to shine, one day. I talk about it and using it on a Mac with HiDPI display modes in this blog post from several years back: https://bytecellar.com/2022/11/08/4k-scaling-is-not-a-problem-on-moder…

For reference, this [0] is Amiga Four Byte Burger, and it looks impossibly good. [0]: https://bytecellar.com/2023/04/24/lost-amiga-four-byte-burger-painting…

Blake Patterson has a beautiful tribute to No Man's Sky[1] done on an Amiga 1000 if anyone wants to see one in action. I really love his more recent Amiga retrospective[2] and he has a great Amiga 1000 photo album[3] too.

OMG that Epyx joystick [1] in the screenshot brings it all flooding back! I hated that thing so much that I went to my local arcade parts dealer, bought a stick and buttons, built a plexiglass housing and circuit board (designed in Deluxe Paint) in the electronics lab at my high school, and cannibalized that horrible Epyx joystick for its plug. Best decision I ever made! SOTB and Turrican were so much nicer with an arcade stick. I even added toggle switches to reroute one of the buttons to "up" (since many games used up for jump). I still have the buttons and joystick, though the home-built plexiglas housing didn't fare so well over the years. [1] https://bytecellar.com/wp-content/uploads/2020/10/a2000.jpg

The Obscuritory -- https://obscuritory.com/ -- if you have any interest in the culture surrounding computer games or retrocomputing or even just obscure, weird things in general I can not recommend this enough OS/2 Museum -- https://www.os2museum.com/ Fun With Virtualization -- https://virtuallyfun.com/ The Old New Thing -- https://devblogs.microsoft.com/oldnewthing The Byte Cellar -- https://bytecellar.com/ McMansion Hell -- https://mcmansionhell.com/

"High" being relative and constantly changing, of course. The SGI 1600SW from 1998 was 1600x1024 at 17.3 inches, so 110dpi. A beautiful thing, but not really like paper IMHO. https://bytecellar.com/2008/02/13/the_sgi_1600sw/ && https://en.wikipedia.org/wiki/SGI_1600SW

Rosetta on the M1 enables the total store ordering from x86, which has a stronger memory model than that of ARM. It also can compute the parity flag in hardware <https://bytecellar.com/2022/11/16/a-secret-apple-silicon-extension-to-…

By the title I thought this would be about the early 80s and e.g. this Electronic Arts ad/poster: https://bytecellar.com/2009/09/30/i_started_life/

Interestingly, the two oddball ALU flags (PF and AF) live on in at least one modern arch. Apple Silicon has an undocumented extension to calculate those and store them in unused ARM flag bits. Having Rosetta manually calculate those on each of the ALU ops (or at least the ones the compiler can't remove the flag calculation of) would massively cut into it's speed. And apparently Apple either had traces of them being used or enough fear that someone important was still using them in order to include hardware support. https://bytecellar.com/2022/11/16/a-secret-apple-silicon-extension-to-…

TIL the WiFi232 (linked to in TFA) exists. Wow! https://bytecellar.com/2017/05/30/the-wonderful-wifi232-bbsing-has-lit…

This site seems to be out of date: the current development site seems to be https://sourceforge.net/projects/previous/ while https://bytecellar.com/2018/04/25/bbsing-on-a-virtual-next-cube-thanks… seems to have some relevant links too. How does the experience of running NeXTStep or OpenStep in Previous compare to that of running x86 OpenStep or NeXTStep https://www.youtube.com/watch?v=Rz2nPJGx4Qg on x86 hardware, on an old x86 box as in https://www.youtube.com/watch?v=Rz2nPJGx4Qg or on a modern x86 system?

Backus-Naur diagrams are sweet. I used to covet the one that Apple put out for Apple Pascal: https://www.bytecellar.com/2004/06/15/apples_pascal_s/

Pshaw, it's raster and since it doesn't fit 80 columns in I can't play nethack on it! I've been meaning to get an Apple IIc to use as a serial terminal: http://www.bytecellar.com/archives/000113.php I've had some Wyse terms before that sucked, and I've unsuccessfully bid on eBay for ADM-3A terminals before, but I kind of ran out of steam on pure-hardware terminals when I discovered that GNU Screen can open character devices directly! I only need to get a serial console on something a few times a year, but when I do I really need it to work, whether I'm getting console on a network device, an embedded ultrasound machine, or a case full of modems I'm hacking. GNU Screen satisfies that need perfectly, especially since I'm always working in it already. I like the idea of the Apple IIc terminal because it combines the warm fuzzies of ancient greenscreen hardware with the not-sucking-ass of a pure-software terminal emulator implementation. That it's cute and diminutive is a bonus.
