Re: dflat language update

Hey iss, I heard you like port PR's in your PR, so I put Darwin in a PR of your PR for you to submit as a new PR .. @ibisum : Great! Done. Does as65 exist on Linux... Yes, I've downloaded from (bottom of) this PAGE the file AS65 [1.42] Assembler for R6502/65SC02 microprocessor. . as65_142.zip conta...

Re: dflat language update

As promised here is the PR for Linux port: https://github.com/6502Nerd/dflat/pull/1 This quick port allows compiling of the 3 command-line utilities and 'dflat.rom' + proper 'dflat.pch' file. Some work is needed for full portability (i.e. for big-endian platforms) - mainly the WAV-header structure a...

Re: dflat language update

Well, you woke my interest in porting the build system under Linux ;), ...with no special Windows includes. The "security" variant of some functions are undefined under Linux/Posix i.e. fopen_s, _itoa_s, strcpy_s, etc. but this is easy fix. What I'll do first - a script to translate as65 syntax to x...

Re: Oric on VGA monitors

@HigashiJun, @Symoon : What models are your 15 kHz compatible VGA monitors? Oric outputs the CSYNC signal as negative pulses - are the Sync Striker output HSYNC/VSYNC compatible with the monitor requirements? Else thanks to this thread, I recall that I should have some old VGA monitors buried somew...

@ dizzy33 : Thanks for the interest and good questions :). ...moving the switch may let your finger push the capacitor. The micro-switch and the capacitor are close, but the switch can be easy manipulated with fingers - no danger for mechanical damages on both (capacitor and switch). It's possible t...

Re: dflat language update

Congrats! dflat looks cool and I like small caps :). But I have one recommendation - change the names of ROM/PCH files to dflat.rom/dflat.pch , because: - dflat sounds not bad as name and is self-explaining for the file content; - it's really easy to change one line in 'oricutron.cfg', so the custom...

Re: Wolfenstein / DOOM for Oric : has this been done?

I don't manage to have the text written below the hires part of the screen... The 3 text lines in HIRES have index 25,26,27 (where the first screen line has index 0 and starts at address 0xbb80), so you need to call AdvancedPrint with 'y' parameter one of the 25,26 or 27. Another problem is this 3 ...

Re: Oric on VGA monitors

In short: unfortunately, direct wiring will not work. By strict spec VGA input requires separate H-Sync and V-Sync. There is no straight "just wiring" solution. Here are 3 possible variants (the simplest first): - https://www.electroschematics.com/sync-signal-separator/ - https://www.retrorgb.com/sy...

In the above attached @Symoon's zip-file the longest name is "only" JOYSTICK CONTROL (i.e. without "LER"). This are 16 bytes and the ROM 1.1b routine (for 1.0 is slightly different...

Re: OPEL Software for the Oric

Great work @Dbug! The joystick utility will be very helpful and even more as part of the OSDK. What is the bug related to the C compiler? About the OPEL's code: you found all "secrets" which I discovered (are there more?). To summarize what I found as interesting: 1. Merging machine code with BASIC ...
