<div dir="ltr">Joseph,<div><br></div><div>I can't think of a good way to explain the specific differences as a lot has changed. I'm pretty sure that none of the open source options out there, despite their claims, *really* offers 100% Blue Book compatibility. Cuis (and Squeak) probably offer reasonable to very good compatibility through chapter 16. There may be some differences here and there, but this is pretty core stuff that I don't believe has changed much. Chapter 17 on is mostly going to be very different and not something you're likely to find in today's implementations. Conceptually, most of the functionality still exists but when Squeak moved to Morphic most things got renamed/restructured/rethought. In the 25 years since, things have continued to evolve even further away from those later chapters in the book.</div><div><br></div><div>If you really want to try to follow the Blue Book, I think the Smalltalk-78 Javascript implementation at <a href="https://smalltalkzoo.thechm.org/HOPL-St78.html">https://smalltalkzoo.thechm.org/HOPL-St78.html</a> might be the closest thing out there.</div><div><br></div><div>Thanks,</div><div>Phil</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Jul 22, 2021 at 12:33 PM Joseph Turco <<a href="mailto:jturk90@protonmail.com">jturk90@protonmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hello all.

The tweaks improved the situation on the BBB rev. C.<br>
I will add to the youtube video the procedure as a comment. <br>
<br>
Still, i will upgrade the BBB to a larger machine, probaby BB AI,
this is the lesser evil to me. <br>

Hey Juan,<br>
<br>
<br>
I tried your tweaks and it did help! Its still a tad slow. The
amount of memory left is 170M<br>

<br>
Ok. The cog version from opensmalltalk is the fastest.<br>
<br>
One thing you can try is to evaluate<br>
<br>
Preferences slowMachine<br>
<br>
This disables some things that are nice to have, but it gives
better response on a slow machine. After that, do <br>
<br>
self runningWorld color: Color veryLightGray;
hideTaskbar<br>
<br>
to remove the expensive taskbar, and for a more tolerable
background color. You might still prefer to enable syntax
highlighting:<br>
<br>
Preferences enable: #syntaxHighlightingAsYouType<br>
<br>
Additionally, this might further improve performance:<br>
<br>
Preferences disable: #subPixelRenderColorFonts<br>
<br>
Besides, 512mb ram is less than ideal. Please check how much ram
you have free when starting cuis. Perhaps we can help reduce it
a bit if needed.<br>
<br>
I never used a RasPI zero, but I find Cuis usable on a RasPI3B,
if the cog VM is used. I hope this helps.<br>
<br>
Cheers,<br>

<div>Yeah
see I think that's my problem. Its a RPI zero w. 512mb
ram and a single core 1ghz processor. I guess it needs
a RPI 3b+ and faster. Oh well I guess its smalltalk-80
for now. <br>
