    IBM was a weird place in the 80s. Its depth and breadth had so many quirks in it. If you had the money - IBM would or could build you just about anthing.

    All kinds of internal tools and utilities that never shipped. Friends who were lucky enough to intern there in the summer came home with all kinds of goodies. They had a laplink-like utility that was lightning fast that could hook two machines together over RS232. easy and fast. beat copying files to floppies and doing sneakernet when upgrading.

    IMHO, Given how the site works for scoring, commenting the article is slop just pushes this to the top of the main page faster.

    If you want to bury this kind content - make a worthwhile comment in another topic and this page will tumbleweed away with its one point.

    Technical difference. Shipping and operating in the wild. The vax / pdp11 rabbit hole gets deeper and deeper .

    You have been here correct? https://en.wikipedia.org/wiki/MouseText

    I can't prove it but I suspect that the Bánffy, Ricardo cited in reference 3 and 4 is the rbanffy seen here and on the orange site. maybe these are bread crumbs to help your quest. apologies if you knew these details already.

      Thanks for the pointers. Yes, I know the MouseText characters are present in Unicode, but it doesn't describe how they were intended to be used, it just provides them for compatibility.

      For example, the screenshot in the 1985 Apple II HIG shows something like the character at 5E (in the table on Wikipedia) being used for the close box at the upper-left... but is that intended? The character at 5E doesn't have a left-hand edge, and I'm guessing that it's supposed to be used next to the character at 5A to provide that left-hand edge, but that's just my guess. I'd like to find some more reliable source.

    The Lisa guidance is a revelation of what Apple knew to be true and required for applications and documents in a graphical world. Of course some things came and went but so so much was right if you read that origainl 1980 document.

    This is cool. In my mind this is what I though the Data General "Eagle" CPU would look like during the events described in the _The Soul of a New Machine_.

    It’s crazy to think that this collection of boards and wirewrap would be transformed into a set of chips that became the beloved Amiga. I assume it goes from CAD to wire wrap and if it "works" the CAD is sent to fabrication on real silicon ?

      I helped Dale set up these boards and other materials for the Amiga 040th at the Computer History Museum back in August. I mounted one of the original chip schematic sheets on some foam core board (very carefully) and hung it up. That sheet was neatly hand drawn and I didn't see any CAD in material he brought.

      I haven't asked Dale specifically if there was any CAD used for Lorraine but from other things I've read about chip design around that time, CAD was just being introduced and pretty rare. These prototypes were first debugged and brought to a working state over Nov/Dec 83 and were shown in the private room at Amiga's CES booth in Jan 84. In 82/83 any computer even capable of complex chip design would have been an expensive minicomputer with an esoteric graphics terminal add-on and Amiga was a startup on a limited budget.

      To a first approximation, yeah, that's basically the process.

    I think you need a beefier Amiga like an A3000 to do that. But I could be pleasantly surprised....

    C64 in north america was ubiqitous and probably one of the first network effects. My friends Zach and Josh and traded games back and forth effectively doubling their game library. Quality was superiour to the 2600 and the NES wouldn't be out for a few more years. definitely a sweet spot.

    The killer app for a high school kid was a word processor and printer. Really couldn't do that with a dedicated console. Teachers were inclinded to give better marks for typed content that obviously easier to read than the chicken scratch that passed for cursive. With spell check, that was the ultimate cheet code.

    ChatGPT and Grok indicated to me that this is likely LLM assisted but not fully LLM generated. Example in this related link : https://slicker.me/emulator.htm - the heading about "caution find something better to do" is just against the LLM ethos. I've seen graduate level draft papers with "As an LLM..." stuck in them so I get your frustration.

    I will leave it to our benevolant overlord to decide if the site should be in the kill file. I am more than happy to comply if that is the will of the site.

    Asking for a friend. Does macOS here mean classic Mac OS or osx/macos ?

    • Screwtapello 10 days ago
      The Apple Network Server in question was made before Jobs returned to Apple and brought OS X with him, so it means classic Mac OS.

    • classichasclass 10 days ago
      Classic Mac OS. It will run up to Mac OS 9.

      XPostFacto might be able to drag it over the finish line, but I suspect there will be a driver problem. No way to know until we can get a system up with these ROMs, of course.
