Csepp 🌢Hey <a href="https://merveilles.town/tags/Casio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Casio</a> I have some questions...enum bool {FALSE=0, TRUE=1, HALF=2};cc: <a href="https://merveilles.town/tags/C" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#C</a> <a href="https://merveilles.town/tags/PocketViewer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PocketViewer</a>

Csepp 🌢May be of interest to <a href="https://merveilles.town/tags/PocketViewer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PocketViewer</a> and <a href="https://merveilles.town/tags/BASIC" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BASIC</a> fans: I imported the Mercurial repo <a href="https://merveilles.town/tags/OWBasic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OWBasic</a> into a Git repo on <a href="https://merveilles.town/tags/Sourcehut" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Sourcehut</a>: <a href="https://git.sr.ht/~raingloom/owbasic" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://git.sr.ht/~raingloom/owbasic</a>

Csepp 🌢Adding <a href="https://merveilles.town/tags/AutoHotkey" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AutoHotkey</a> to the list of cautionary examples of ad-hoc scripting languages. But I'm still glad it exists, now I can start automating the <a href="https://merveilles.town/tags/PocketViewer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PocketViewer</a> simulator. Opening it is already so much faster. But ideally I'd still prefer to reverse engineer it enough to use Frida to add some automation and maybe even a GDB stub. <a href="https://merveilles.town/tags/theWorkshop" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#theWorkshop</a>

Csepp 🌢At the portion of my <a href="https://merveilles.town/tags/PocketViewer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PocketViewer</a> hacking where I have to become intimately familiar with Wine and Windows GUI automation. <a href="https://merveilles.town/tags/theWorkshop" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#theWorkshop</a>

Csepp 🌢Don't wanna jinx it yet, so all I'm gonna say is that the <a href="https://merveilles.town/tags/CollapseOS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CollapseOS</a> <a href="https://merveilles.town/tags/PocketViewer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PocketViewer</a> ROM writer is finally picking up steam. :neofox_owo: <a href="https://merveilles.town/tags/theFoundry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#theFoundry</a> <a href="https://merveilles.town/tags/theWorkshop" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#theWorkshop</a>

Csepp 🌢<a href="https://merveilles.town/tags/ReverseEngineering" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ReverseEngineering</a> / <a href="https://merveilles.town/tags/embedded" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#embedded</a> folx, is it possible that a boot ROM is mapped near the end of the address space such that some of its contents wrap around? See: <a href="https://github.com/NationalSecurityAgency/ghidra/issues/7917" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/NationalSecurityAgency/ghidra/issues/7917</a> Context: I'm trying to figure out the memory map for the <a href="https://merveilles.town/tags/PocketViewer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PocketViewer</a> .

Jon Moller<a href="https://merveilles.town/@csepp" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@csepp</a> <a href="https://mastodon.online/@hblaub" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@hblaub</a> Hi all! I recently managed a successful synchronization of my <a href="https://mastodon.sdf.org/tags/Casio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Casio</a> <a href="https://mastodon.sdf.org/tags/PocketViewer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PocketViewer</a> <a href="https://mastodon.sdf.org/tags/PVS400Plus" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PVS400Plus</a> with <a href="https://mastodon.sdf.org/tags/caleidlink" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#caleidlink</a>/#pvlink but couldn't install addins or synchronize sheets. Have either of you managed to sync either? I thought I'd ask after following this Mastodon thread: <a href="https://merveilles.town/@hblaub@mastodon.online/113149241582160220" rel="nofollow noopener noreferrer" target="_blank">https://merveilles.town/@hblaub@mastodon.online/113149241582160220</a>

Jon Moller<a href="https://merveilles.town/@csepp" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@csepp</a> I saw that you've been working on reverse engineering the <a href="https://mastodon.sdf.org/tags/casio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#casio</a> <a href="https://mastodon.sdf.org/tags/pocketviewer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#pocketviewer</a> and using its <a href="https://mastodon.sdf.org/tags/sdk" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sdk</a> in <a href="https://mastodon.sdf.org/tags/wine" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#wine</a>. Is enough of the <a href="https://mastodon.sdf.org/tags/sdk" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sdk</a> documented that we could prepare a <a href="https://mastodon.sdf.org/tags/linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#linux</a> version? I just compiled <a href="https://mastodon.sdf.org/tags/caleidlink" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#caleidlink</a> <a href="https://mastodon.sdf.org/tags/pvlink" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#pvlink</a> on my thin client to try syncing my <a href="https://mastodon.sdf.org/tags/pvs400plus" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#pvs400plus</a>. <a href="https://mastodon.sdf.org/tags/pda" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#pda</a>

Harry Blauberg<a href="https://merveilles.town/@csepp" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@csepp</a> Would you be interested to talk about <a href="https://mastodon.online/tags/PocketViewer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PocketViewer</a> ?

Csepp 🌢> How Wozniak’s code for the <a href="https://merveilles.town/tags/Apple1" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Apple1</a> works <a href="https://redirect.invidious.io/watch?v=SpG8rgI7Hec" rel="nofollow noopener noreferrer" target="_blank">https://redirect.invidious.io/watch?v=SpG8rgI7Hec</a> Great video by <a href="https://merveilles.town/tags/BenEater" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BenEater</a> on the <a href="https://merveilles.town/tags/MOS6502" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MOS6502</a> machine monitor. I'm working on some low-level <a href="https://merveilles.town/tags/PocketViewer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PocketViewer</a> stuff in <a href="https://merveilles.town/tags/theFoundry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#theFoundry</a> , so I found it especially useful. Probably won't go to this level of optimization though, at least not for the first implementation.

Csepp 🌢Made some progress in making the <a href="https://merveilles.town/tags/PocketViewer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PocketViewer</a> SDK more usable under Wine with some wrapper scripts. UwU <a href="https://merveilles.town/tags/theWorkshop" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#theWorkshop</a>

Csepp 🌢Figured out how to install <a href="https://merveilles.town/tags/OWBasic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OWBasic</a> (a <a href="https://merveilles.town/tags/Basic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Basic</a> implementation) onto my <a href="https://merveilles.town/tags/PocketViewer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PocketViewer</a> ! Turns out the PV application manager errors I was getting were misleading. The import function doesn't seem to work, but I can upload files to the device just fine. So now I have the interpreter, a reference browser, and the OWB reference docs all on the PV. :moomin_happy: ! And I won't need the Windows 98 machine after all and can continue developing under Wine. <a href="https://merveilles.town/tags/theWorkshop" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#theWorkshop</a>

Csepp 🌢Hrmm, I think I'm better off setting up one of the old computers I have as a dedicated old-Windows machine. Emulating old <a href="https://merveilles.town/tags/Windows" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Windows</a> versions with <a href="https://merveilles.town/tags/QEMU" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#QEMU</a> is too fiddly (especially shared folder support) and I am never quite sure if Wine is emulating something correctly, especially with physical serial port access being involved. I need to validate if the <a href="https://merveilles.town/tags/PocketViewer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PocketViewer</a> SDK works on real hardware. cc: <a href="https://merveilles.town/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#retrocomputing</a> <a href="https://merveilles.town/tags/theWorkshop" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#theWorkshop</a>

Csepp 🌢I should be sleeping but I found more still online <a href="https://merveilles.town/tags/PocketViewer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PocketViewer</a> sites. OwO <a href="https://mcpvc.stackeffect.de/index_en.html" rel="nofollow noopener noreferrer" target="_blank">https://mcpvc.stackeffect.de/index_en.html</a>

Csepp 🌢Got a <a href="https://merveilles.town/tags/PocketViewer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PocketViewer</a> in its original box with a dock. :moomin_yay: I can finally transfer files between it and my PC. UwU

Csepp 🌢Trying to reverse engineer the x86 emulator in sim3022.exe from the <a href="https://merveilles.town/tags/PocketViewer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PocketViewer</a> SDK. Or rather, trying to locate it in the relatively massive GUI app. I have some candidates that look like they are doing instruction or operand decoding.

Csepp 🌢I envy those who do not choose projects where they have to learn about 16 bit <a href="https://merveilles.town/tags/x86" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#x86</a> segmentation. I'm digging deeper and deeper into the <a href="https://merveilles.town/tags/PocketViewer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PocketViewer</a> SDK in <a href="https://merveilles.town/tags/theFoundry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#theFoundry</a> and it was pretty messed up when I realized that I was incorrectly converting 32 bit addresses to segmented ones.

Csepp 🌢Trying to figure out the architecture for a somewhat self-hosting OS for the <a href="https://merveilles.town/tags/PocketViewer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PocketViewer</a>. Instead of sleeping. <a href="https://merveilles.town/tags/CollapseOS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CollapseOS</a> would only give me access to about 28K of near addressable RAM, but maybe that would be enough? I don't see much point in scrapping the existing OS though and its standard library would be nice to have access to. Well... I guess I could start by shipping cOS as a C application and providing a C call primitive...?
