Re: Disk conversion - with XP

Can't find what means "read fault 10", if somebody can help. Anyway, Track #14 Sector #01 should not be modified by OricFS except if you modify the hidden file .source in the mounted filesystem. If you can't send the disk image, can you tell your friend to type the following commands in the mounted ...

Re: Disk conversion - with XP

Ok, I will check Sedoric manual to see what means "read fault 10".
Do you know if the disk image is a fresh one generated by OricFs or by another tool?

Maybe you can send me the disk image so I could see what's wrong.

Re: Disk conversion - with XP

@Chema: can tell me
  • the OS version on the image disk (ie Sedoric 2 / FT-DOS 3.2,...)
  • the operations you do (was it adding and removing the same file, was it with the emulator or through OricFs,...).
  • The emulator you use
So i can try to reproduce this issue.
Thanks

Hi,

About FUSE driver, you can do all what you want even mount a web site or a database.

I posted a message last year in this topic about such a tool for Oric dsk images.
More information can be found here (in french)

Re: VirtualBasic and Oric

Something like Magic Gosub was published in Theoric #29 pages 40-43. Here is a tap file with BASIC loader and test (Atmos version) The test part: 30 CLS 40 INPUT "Numero de menu ";N 50 ON N GOSUB "MENU1","MENU2","MENU3" 60 GOTO 40 100 ' "MENU1" 110 PRINT "Menu1":RETURN 120 ' "MENU2" 130 PRINT "Menu2...

Re: not a 'game' but.....

I did not know this utility but it seems to be similar to another one called Minicomp and published in A.N.A.L.O.G Computing Magazine #23 (October 1984) page It was for Atari 800 computer. The BASIC subset was only 11 instructions: A=ccc A=B A=B+C A=B-C END IF A=B THEN nnn IF A<B THEN nnn GOTO nnn G...

Oricutron : ADC / SBC not properly handle V flag?

Hi Xeron, I have a program that does not work with Oricutron but works well with Euphoric. After some digging, I think intructions ADC and SBC do not properly handle the V flag (at least in binary mode) This code should end at $500A with V flag set: 5000 CLC 5001 CLV 5002 LDA #$B4 5004 ADC #$B4 5006...

Oricutron Jasmin auto-boot not working

I'm working with Linux and now that Oricutron can use a keymap, I tested it to replace DosBox+Euphoric. A new behavior was added between v1.0 and 1.1: jasmin auto-boot but unfortunately it does not work as expected. With oric-1, the "Ready" prompt is replaced by "Printer error" and with atmos some c...

ID AM is "ID Address Mark", it is just before the beginning of a sector. A track is composed by: [GAP1][sector 1][sector 2]...[GAP5] A sector is: [GAP2][Index][GAP3][Data][GAP4] Here is Track 0 / sector 1 / Side 0 (from a Sedoric disk image): Start of track 00000100 4e 4e 4e 4e 4e 4e 4e 4e 4e 4e 4e ...

Re: Track reading (Sedoric / FDC)

I watched the code at $CFCD, it disable only T1 interrupts but this should be sufficient: CFD4- LDA #$40 CFD6- STA #$30E Reading is done by polling the DRQ register ($318) then reading the Data Register ($313) and so on until the FDC issues an IRQ indicating the end of the command or an error (subro...

Re: Track reading (Sedoric / FDC)

What's even more puzzling is that somtimes the C2 bytes crush other bytes, and sometimes they are inserted between two bytes (I could see that by saving the reading buffer and comparing several readings of the same track) Does it means you don't have the same number of bytes read every time? Maybe ...

Re: Track reading (Sedoric / FDC)

This is very strange because you always get $C2 bytes. $C2 is a SYNC byte (of course you can find some in the datas). I think there is one $C2 somewhere on a sector, so Euphoric is right because there is 3 $C2 bytes at the beginning of each track. On a real hardware you should find only 2 $C2 bytes ...

Re: Oricutron for android (POC)

Hi,

Tested on ASUS EeePad TF101 with Android v4.0.3: Barbitoric works at 50fps but the Keyboard dock isn't working (only [ENTER] and some CTRL+[key] sequences).
What is the [1] in the lower right corner?
