how did you change the charset in the rom-file? Is there an instruction somewhere how to do this? Welcome here, @maprix! The above German ROM is original one and I didn't modified the charset in it. But changing the font in a ROM file is possible. Unfortunately there is no easy way i.e. no nice vis...

Technically you could also install your low bank in page 2 instead of page 4 (assuming you are not already using the page 2 for internal variables), that would give 256 additional bytes for the programs.
...It should work on Jasmin but doesn't and I don't know why. Well, it works! :D As soon as I read about the problem I thought of the reason - it costed me about a week head scratching when I worked on my ' quadro-booter '! It's general hardware rule after reset most (if not all) peripheral chips t...
The fastest way is absolute addressing without indexing. Or: 112 lines x 40 bytes x 3 byte for STA = 13440 bytes (hex: #3480) which is OK for experiments. :lol: You can generate the "program" from BASIC and here you are: 10 ' 1FFC 78 SEI 11 ' 1FFD A2 10 LDX #$10 12 ' 1FFF 8A TXA 13 ' ........
Welcome here! Replied in X too: https://twitter.com/oric_iss/status/1687227076628099072 I'll check what's the issue with Jasmin and will add support for other 2 controllers. Also I can (and will) test with real hardware. There are some problems with the build (like undefined function 'cpm_parse_file...
Hi all! Some news about the # Oricon project: https://twitter.com/oric_iss/status/1683832139417272322 The project goes bit slower that I wish bit it's already in the final phase! :D I'm preparing lot of stuff for the hardware - demos, source code for diagnostics and communication programs. The best ...
... Please, read the 4 previous posts! From formal point of view the byte should be $00 to indicate BASIC code (full stop) :). But let's push things further - what if we left it "as is" i.e. $80 and make the TAP autostart ... meme-contest.jpg I am announcing a prize-less just for fun BASI...
Does it matter if the header says machine-code? Yes, definitely when basic startup code is used the header byte must be set to $00. The ROM loading routine checks it and uses different handling of the loaded data dependent on this byte . If it's machine code then Oric simply jumps in the void: :) J...
Screenshot_20230709_154715.jpg LOADVADER, LOADLUKE, LOADLEIA - nothing works ! So, the problem isn't with Star Wars! :lol: The issue is with the part 'LOAD' which is reserved word. Use LOAD"LOADVADER" instead... Sometimes adding '!' and double quotation helps too. Also check if the TAP is...
Now finally the Oric starts!!!!!!!!! But I have issues with the keyboard... Congrats, another Oric lives! Check closely all soldering pads of key switches and cable. Check if the newly soldered sockets really make a good contact - I had such magic and exactly on fixing key issues - when I measured ...
