It is done. That transparent transfer tape is TERRIBLE. Barely any sticky. #WouldNotRecommend. If I were to do it again I think I’d make white be the bottom-most layer and put a white border around the whole thing. #maker #TRS80 #CoCo #RadioShack
the finale of Marooned, including one of the most absurd puzzles I have ever run across
with the asterisk this was an unfinished game, and I get into why I think it was left in the state it was

Today for All the Adventures I have a most unusual post as a game by Kim Watt (likely from 1980) was left in a non-functional state by the author and now is fixed and playable for the first time.

I'm not really *planning* on doing any TRS-80 stuff, but found a few books that look interesting:
Seems like the most practical book, but the scan is annoying 2-page layout, I'm making a new cbz of it right now:

And some BASIC:

does anyone that I’m connected to #repair old TRS-80 Color Computers (or is connected to anyone who does) & is based even vaguely anywhere near #Canberra? (or within plausible shipping distance)
I wish to exchange $$ for goods & services to put the #MagicBlueSmoke back into my beloved old #CoCo1…

always liked the tandy trs-80 color computer cartridge boxes. they're small, elegant, and have uniquely colourful and weird cover art
apparently the creator of this game - dale lear - re-released it for iOS:

Also, the booklet that started it for me:

Next for All the Adventures, come for a tale of computer generated swordfights, chess, and frontal lobotomies as I play the wildly ambitious Bedlam (1982).
Includes characters with randomized motivations and multiple endings!
Next on All the Adventures, I play the first three "Misadventures", naughty games by the "Softcore Software Co." via Bob Krotts of Dayton, Ohio.

Starting a fresh new profile, let's introduce me.
I'm Nicolas from north of France, I like old computers, I have a collection of #amiga, #C64, #amstrad, #atari. I also like #computerhistory and started to code emulators, I made a #teletype, #altair and #Intel8080 emulator, and also a #Z80 then a #trs80 emulator coded in #rust. Currently experimenting with #Zig, and #riscv64 assembly.
After much testing and code comparison, the new Feb 2025 Release of #Vezza - my #z80 high speed #zmachine is ready! Took way longer than expected to synchronize across all of the code bases, particularly making sure that all optimizations made it across all platforms - TRS-80 model 1, TRS-80 model 3, TRS-80 model 4, the CP/M versions (~18 platforms), the embedded versions (Spectrum tape, TEC-1G), and slowly pushing into the Agon Light version (which has even more updates still in progress). Lots of individual tweaks, and some major rethinks and rewrites have come together to accelerate game play.
The hardest part of rewriting in this update involved rewriting the dictionary search code. I ended up going back to the original jzip interpreter, written in C for Unix waaay back when. Jzip provided much of the logic that went into ZXZVM, which provided the base for #M4ZVM #M3ZVM and #Vezza. Going back to Jzip made sense as Jzip has an even longer history; and is highly tested and stable and still maintained. This research gave me the confidence that the streamlining and changes I was making to such a fundamental part of the game would work, making all inputted dictionary searching more efficient.
To work around how CP/M stores executable files I spent a lot of time re-organising the memory map to make the executable smaller. This involved rearranging where the initialization code was stored inside the increasingly complex layout. Support across multiple versions means I needed to break up variable sized code and strings to sit inside variable sized gaps, while still compiling all the CP/M versions from the same interconnected set of source files. It needed quite a few manual checks to ensure that it all worked.
What this all means is that your favourite #infocom #punyinform and other text adventures will all play on your favourite z80 #retrocomputing platforms even faster than before!

I wrote a Pomodoro timer program on a TRS-80 that sounds an alarm after a certain amount of time.

A new version of #ugBASIC, the open source isomorphic #BASIC compiler, has been released for #TRS80 #ColorComputer 1/2 and 3 (check under Hardware > Targets).
ugBASIC is a cross-compiler for #Linux and #Windows, for writing simple language games, that can run on dozens of different home computers, and 8-bit consoles.
There is also a convenient built-in IDE for Microsoft Windows, and even a sandbox.
My Radio Shack Pocket Computer 1 has arrived!
Will get some batteries and see if it works. Printer & Cassette interface looks good.
