September 4, 2023 – September 2023 Issue of TRS8Bit

Dusty has released the September 2023 issue of the TRS8Bit newsletter. Here’s what he had to say:

The September 2023 edition of TRS8BIT is now available from the Downloads page.
In this issue (one of the largest September issues ever!). Ian Mavric reports what to look for at the T.A.2023, gives us the low-down on M3 & M4 power supplies and continues his article on restoring and upgrading the Co-Co3. Leon Heller found some very interesting, Tandy related websites. New contributor, Tu-Bardh, has converted a ‘PET’ number-sorting game program for us all to enjoy.
E.T. Fonehume has another BASIC one-liner, zapping stars! Vince Otten has part 2 of his ‘Software tools in BASIC’. ‘At the READY> prompt’ shows a quirk in a FOR-NEXT loop. Andy tells us how the ‘Tandy-thing’ happened for him. ‘The Way We Were’ looks at BASIC compilers, TRS-80 software and a Model 2000 review. Pascal Holdry offers an early look at his current hardware project. Handy Hints is just for any model railway buffs out there. Peter Phillips sorts out a 40+ year old bug in David Ahl’s maze generating program. Another new contributor, Wellswang, runs across hardware problems and a manual miss-print which caused rather a bit of confusion.
Tom Nardi restores the cheapest Tandy at a swap-meet. Want to see a M3 using A.I. on the internet; yeh, I couldn’t believe it too. And finally, there’s the details of this years competition. Don’t forget, time’s running out to get your entries in. George Phillips has updated his competition page with information on the structure of Z-80 opcodes and an example disassembler.
Thanks to everyone who has contributed to this issue.

September 3, 2023 – TRS80GP v2.5.1 Released

TRS80GP has been updated to v2.5.1. Release Notes:

Changes – Model I/III/4:

  • Linux joystick support.
  • Type current date/time with -iy ‘%m/%d/%y’ or -iy ‘%h:%i:%s’; %Y is full year. Model 2 users: trs80gp -m2 -iw YYYY -iy “%m/%d/%Y\r%h.%i.%s\r”
  • Model 1 CLOAD fixed when using earlier ROM revisions under TRSDOS.
  • Warning if cassette used on Model 1 disk system without CMD”T” with option to turn off interrupts so cassette operation will function properly.
  • halt, irq, nmi states in Z-80 in disassembly for less confusing stepping.

Changes – Other Computers:

  • Support Color Computer SG-8 semigraphics mode
  • Sound now audible on Color Computer Demon Attack.
  • Implemented import/export of Model II TRS-DOS variable length record files.
  • Approximate video beam dropouts in Model 2/12/16/6000.

Bug Fixes:

  • Color Computer reset works when in OS-9 or 64K mode in general.
  • Color Flex 5.0.4 keyboard input fixed (it was seeing entire columns at once).
  • Linux “Change Model” would fail if trs80gp was not on the $PATH.
  • Correctly exports first file on Aculab wafer rather than ejecting the wafer.
  • Some illegal EXG instructions could crash Videotex or CoCo.
  • FreHD emulation bug on Windows prevented access to files with paths.
  • Model 1 LEVEL II BASIC data .cas files no longer mis-identified as 250 baud.
  • Stopped Z-80 suprious breakpoints in halt state or when interrupt pending.
  • Color Computer Program Paks were limited to 8K due to a typo.
  • 68000 execution speed more realistic and decoupled from Z-80.
  • 68000 speed selectable with -mhz16 N, default 8; closest to divisor of 312.
  • Scroll Lock and ctrl+shift+@ now work as Model 2/12/16/6000 HOLD key on linux. And \0 will also simulate HOLD when used in -i or an Alt+N macro.

August 26, 2023 – Scott Taylor releases another game

Scott Taylor has released another one of his games, “Forest Fire.” He writes

“Forest Fire” is a simulation game for one player. The object of the game is to extinguish a growing fire which is threatening the town and farms of the countryside. To do this, you can supervise the construction of barriers which block the path of the fire, or direct a water scooper airplane to skim water from the lake and drop it over a wider area.

You can only move so quickly, so much of the strategy is in deciding what to sacrifice in order to save the most amount of land. The game ends when the fire is completely extinguished. You will then receive a report on the results of the fire, and a skill rating based on how well you protected the town (“#”), farms (“F”), and forest of the area, in that order of importance.

As soon as the game begins you can move, build fire barriers, or collect or drop water by pressing keys on the keyboard. Your initial position is marked by a “+” symbol in the town. The fire will appear as a single “*” symbol in the forest.

You can download Scott’s games by searching the Software Search page for the author field for Scott Taylor
