Question - ROM based computers other than Atari ST?
I’ve got a question which will help me with Postcards from Cutty. In this setting, most modern computers have backdoors. So, some space colonists use miniaturized retro computers to control spacecraft systems.
Currently, I’m thinking they’re mostly based on the Atari ST because it was ROM based, but also the 32 bit 68K CPU code and address space is adequate for most of the tasks required for spacecraft systems. In contrast, 8 bits are just too limited for a lot of things.
But are there other good possible systems to use instead?
Fundamentally, it needs to be something that enthusiasts could pick apart byte-by-byte and transistor-by-transistor to ensure there are no vulnerabilities. So something a bit “small” is good. And it needs to be able to eat its own dog-food. The entire development system needs to be able to run on itself (so - no specialized microcontroller systems).
And ideally, it needs to be popular enough that there would be an enthusiast scene in the first place who will have laboriously picked apart everything byte-by-byte. The Atari ST, of course, is a popular platform for the demo scene.

The original Amiga computer was launched to the public on July 23, 1985, in a legendary demonstration at Lincoln Center in New York featuring the likes of Andy Warhol and Debbie Harry.#RetroComputing #Computers #Commodore #Amiga
Prior to that epic event, however, there was another Amiga - a lesser-known member of the family most have never even heard of. Back in 1984/1985 Commodore created a few hundred “Development Edition” machines called the Amiga Development System. Sometimes, due to a very unique early design, they are also sometimes referred to as “Velvet” which was a name for a particular motherboard layout some had.
Commodore sent these computers to companies around the world in the hopes they would decide to support the new platform in the form of creating software and tools.
Thus, the Development System is a very unique machine most of which have been lost to the sands of time. Prior to this writing it was believed that only 5 Development Systems remained around the world.
Assuming that’s true, there are now six.
I now have in my possession one of the rarest Amigas ever made - one that was never sold to the consumer market. And this one appears to be entirely unique from its brethren, which I shall soon explain.

Some easier stuff that doesn't require persistent shared storage:
1) Post/comment editing : You can edit a post/comment by starting a comment with the line "EDIT". The CSF uses string matching to determine which post/comment this EDIT should replace. (Matches 5 character substrings; the post/comment with the most matches is replaced.)
2) Comment liking : A like is implemented with a comment that looks like "+1 @ user "quoted ... comment". The quoted comment is the start and end of the comment, limited to 20+20 characters.
3) Ignoring comments : Currently, you still see comments made by ignored users. If I can scrape ignored users from https : // pluspora . com / privacy, then it'll be easy for the #CSF to filter out comments made by those users.
4) Personal Hashtags : A personal hashtag looks like #hashtag isaackuo AT pluspora com. The CSF will filter out any "hijack" post. In other words, if it detects a personal hashtag on a post by someone whose name does not match, that post is filtered out.
5) Reply with Commentary : Reply to a post/comment with optional additional commentary below the quoted post/comment ... this would seem somewhat straightforward, but I'm not sure how to translate a post/comment into the required Markdown?
For other features, I need some sort of persistent shared storage (shared between devices by the same user, at least). For example, I want to implement hashtag lines, where you only need to type the first few characters and it'll fill out the rest of the line with a list of hashtags. That will help with Collection-like usage. You type "#ami" and it fills out "#amiga #commodore #retrocomputing #retrocomputing isaackuo AT pluspora com"
Another feature I really want is shared flaglists. This is sort of like Community moderation, but applied to the entire stream. A flaglist has an OWNER, who authorizes MODERATORS to be able to flag users, posts, and comments. The flaglist is implemented as a special post with control comments, maybe? The basic idea is that any flagged users, posts, and comments get filtered out by the #CSF for anyone who "follows" the flaglist.
Additionally, a flaglist could be hashtag specific, providing Community-like function. The flaglist only applies to posts and comments matching the moderated hashtag.
I'm not sure what's a good way to implement this persistent shared storage. I've been thinking in terms of special posts with comments providing the "storage". But maybe there's something better?

The computer is responsible for turning the heat and the air conditioners on and off for 19 school buildings.
"The system controls the start/stop of boilers, the start/stop of fans, pumps, [it]monitors space temperatures, and so on," Hopkins explained.
A Kentwood High School student programmed it when it was installed in the 1980s. Whenever the district has a problem with it, they go back to the original programmer who still lives in the area.
Parts for the computer are difficult to find, Hopkins said. It is on its second mouse and third monitor.
"It's a very unique product. It operates on a 1200-bit modem," said Hopkins. "How it runs, the software that it's running, is unique to Commodore."
Hopkins said the system runs on a radio frequency that sends a signal to school buildings, which reply within a matter of seconds with the status of each building. The only problem is that the computer operates on the same frequency as some of the walkie-talkies used by the maintenance department.
"Because they share the same frequency as our maintenance communications radios and operations maintenance radios -- it depends on what we're doing -- yes, they do interfere," Hopkins said.
If that happens, "we have to clear the radio and get everyone off of it for up to 15 minutes."
If the computer stopped working tomorrow, a staff person would have to turn each building’s climate control systems on and off by hand.
PS/2 Mouse Interface for Amiga, Atari ST and Commodore 64/128
Micromys V5 is the long-awaited successor to Micromys V4. The new version now supports more computers than ever before: #Amiga, #Atari ST/STe/Falcon, #Commodore VIC-20, #C64 and the Atari 8-bit series. With a total of nine different modes of operation, Micromys V5 is probably the most versatile mouse adapter on the market.
Micromys V5 uses the proven automatic computer recognition of its predecessor without the need for DIP switches. The adapter figures out most computer environments automatically, and choosing a mode of operation is done by holding down one or more mouse buttons during power-up.
