How to get more colour & higher Rez on a Falcon?

https://www.atari-forum.com/viewtopic.php?f=27&t=2850 https://www.atari-forum.com/viewtopic.php?f=27&t=10267 https://www.atari-forum.com/viewtopic.php?f=27&t=14325 https://www.atari-forum.com/viewtopic.php?f=27&t=16559
Nova: https://www.atari-forum.com/viewtopic.php?f=27&t=12207

  • With programs like Videlity, Videl Inside, Blow Up, you can get a resolution of 800*592*256 colours easily.
  • For better resolutions with better colour depths, harware mods are needed.
  • You can get normally in 16 bit:
    • RGB/TV: 640*400 (768*480 in overscan)
    • VGA: 320*480 (with tools like "videlity" you get a little bit more)
  • For Mint/Xaaes:
    • 640x480x256 is video=27
    • If you set video to 15 you can choose resolutions from the Screenblaster software.
  • Screen Blaster III drivers here.
  • Modified Nova drivers for the Falcon


Why does the Falcon slowdown in higher video Modes?

https://www.atari-forum.com/viewtopic.php?f=27&t=13270
Bottleneck is the bus to ST RAM. This bus is more occupied by the video chip. The processor sometimes has to wait to get to the data in ST RAM. Slowdown is high when moving big chunks of data in ST RAM (lot of bus time needed). Slowdown is almost zero when heavy computing is done in tight loops that fit in the 68030's processor cache (not much bus access needed).
Chart on Videl's memory consumption is in the thread above.

Can my Falcon use a LCD panel?

https://www.atari-forum.com/viewtopic.php?f=27&t=8708 https://www.atari-forum.com/viewtopic.php?f=27&t=10017
LCD works just fine with every resolution, including ST modes, as well as standard Falcy VGA and extended Centscreen modes. The only reservation with an LCD display is with the frequency. You have to treat an LCD/SVGA as if it were an old fixed-frequency 60hz screen, which is fine for the majority of stuff, but some games and demos like to use weird screen-busting 100hz modes, which an LCD cannot display.

What are the keyboard pins on the Falcon motherboard?

https://www.atari-forum.com/viewtopic.php?f=27&t=10414 

Pin 1 - gnd 
Pin 2 - n/c 
Pin 3 - ide/floppy led 
pin 4 - vcc 
pin 5 - rxd 
pin 6 - txd 
pin 7 - reset 
pin 8 - gnd 
pin 9 - KTOX (Could be KTDX) 
pin 10 - KROX (Could be KRDX)

These first 8 pins are equivalent to the keyboard connector in any ST/STE.

KTOK = KEYBOARD TRANSMIT OPERATION
this signal is connected U52 pin7 and supplys an irq. High pulse when the keyboard interface chip is requesting service to let the keyboard controller chip know there is an operation in progress and to buffer data instead

KROX = KEYBOARD RECIEVE OPERATION
This is an input pin i think used to say im ready {buffer empty etc} pin 150 TOK combel{maybe transmited ok flag or something}

How to reset NVRAM of Falcon??

https://www.atari-forum.com/viewtopic.php?f=27&t=12700 https://www.atari-forum.com/viewtopic.php?f=27&t=12831
When you change the NV RAM chip, do a HARDWARE RESET of the NV RAM (Alt+Ctrl+right Shift+Undo) during bootup screen (Atari logo) because otherwise the system does not accept new settings, besides date/time.

How to fix "Coprocessor protocol violation" issues?

https://www.atari-forum.com/viewtopic.php?f=27&t=10233
I was getting some problems with booting, that I narrowed down to the FPU. I'm not sure why, but I do have quite a bit of hardware hanging off the motherboard (Nemesis and MightySonic32). On bootup, it was hanging around the point it loads the ext2 filesystem driver. Removed FPU, all was fine.

It has some short circuits, on top side you have to cut 2 tracks, on the bottom 3 tracks.
Photo in thread above shows where to cut.

Why does the falcon sometime crashes with graphics error?

https://www.atari-forum.com/viewtopic.php?f=27&t=15450
Graphics errors could be related to RAM problems. Removing the Memory card and putting it back into the falcon may solve the issue.

Can I use a ATX PSU on the Falcon?

https://www.atari-forum.com/viewtopic.php?f=27&t=16381#p147218
You basically only need the +5v / +12v and GND for an atari.
On an ATX PSU these will be
RED = +5v
YELLOW = +12v
BLACK = Ground
So, the Blue wire on an ST is +12v so you can substitute the BLUE on the ST with the YELLOW on the PSU. However, the BLUE on a PC PSU is actually -12v so dont mistake them.
Also, in order to force an ATX PSU to ON, you will need to ground the GREEN wire too! When I did this withe the Mega, I used the GREEN-BLACK shorting with a simple PTM-PTB Switch and this worked a treat.

Can I have a IDE cd-rom or CD Burner on the Falcon?

https://www.atari-forum.com/viewtopic.php?f=27&t=3287 https://www.atari-forum.com/viewtopic.php?f=27&t=7736 https://www.atari-forum.com/viewtopic.php?f=27&t=11752 https://www.atari-forum.com/viewtopic.php?f=27&t=13833 https://www.atari-forum.com/viewtopic.php?f=27&t=16943

  1. I have a 3.5 IDE CD writer connected to my Falcon. I use the Wizztronics 2.5 to 3.5 adapter on the internal IDE port. It gives 2 IDE 3.5 connections. I use SPIN as a driver for the CD writer, but I never tried to burn a CD with it, I use it only as a CD-Rom player. For power, I just connected it to the ATX psu needed by my CT60.
  2. I tried a yamaha cd-writer on my falcon. I store CD images on the IDE HD and had the writer on SCSI. This gave me 4x speed. I burned about 150 CDR's without a single error using CD-LAB by Francois Galea. When reading from CDR to HDD I got about 4.2x speed *g*
  3. HDDriver will pick the drive up, but you still need some other program (like spin, exntedos) to be able to read CDs. CDs have different types of filing system, and AFAIK it's never been added to HDDriver.
  4. You just need a 3-way 44pin IDE cable, one end plug into the motherboard while the 2 other sockets into your IDE devices. A 44pin to 40pin adapter may be needed if your CD drive is 40pin IDE.

Can I have Compact Flash/SD card/SSD on the Falcon?

https://www.atari-forum.com/viewtopic.php?f=27&t=6285 https://www.atari-forum.com/viewtopic.php?f=27&t=6924 https://www.atari-forum.com/viewtopic.php?f=27&t=6931 https://www.atari-forum.com/viewtopic.php?f=27&t=9030 https://www.atari-forum.com/viewtopic.php?f=27&t=11382 https://www.atari-forum.com/viewtopic.php?f=27&t=12130 https://www.atari-forum.com/viewtopic.php?f=27&t=13432 https://www.atari-forum.com/viewtopic.php?f=27&t=15948

  1. yes you can use 2 ide device on the f030
  2. A friend has an IDE CF reader in his Falcon and it works pretty well with the last version of HDDriver. If you want to read DOS-formated CFs, you can use BigDos, Mint or Magic.
  3. I just wanted to let everyone know that I was successful in installing and booting my Falcon from a Compact Flash (CF) card. I tried both 512mb and 1gb cards. I was originally not successful since I was using HDDriver 7.61 (for compatibility with the CT60) This locks up when attempting to boot or ID the CF card. I ended up using ICD Pro Utilities 6.5.5 (I think) and it works fine.
  4. I have been using a CF Adapter and card for yonks now. HD Driver v8 is required to boot from it properly, but then v8 is supposed to have issues with CuBase Audio.
  5. You just need a 3-way 44pin IDE cable, one end plug into the motherboard while the 2 other sockets into your IDE devices. A 44pin to 40pin adapter may be needed if your card reader is 40pin IDE.

What is the speed of a CF on the Falcon?

What is the HDD size limit of the Falcon ?

https://www.atari-forum.com/viewtopic.php?f=27&t=10649

  1. HDdriver states "Support for SCSI drives up to 8192 GByte and IDE drives up to 2048 GByte. For SCSI drives with a capacity > 1 GByte Atari ST and STE require an ICD compatible SCSI host adapter, e. g. the LINK97."
  2. OS limitation:
OS-Release              Size 
---------------------------------------------------------------- 
TOS 1.00 - 1.02        256 MByte 
TOS 1.04 - 3.xx        512 Mbyte 
TOS 4.0x              1024 MByte 

MagiC / BigDOS        1024 MByte 
                      2048 MByte (Compatible Dos) 

MagiC 6.1       FAT32 -> Terrabyte (not MagiC 6.01) 

FreeMiNT 1.15 / FAT16  2048 MByte (DOS/TOS comp. Partition)

Can I connect a ST ASCI drive to a Falcon?

https://www.atari-forum.com/viewtopic.php?f=27&t=5934
Unfortunately the 19pin connector is not SCSI. It's ACSI, that connects to any atari but F030.

How many IDE devices can I put in the Falcon?

https://www.atari-forum.com/viewtopic.php?f=27&t=5826 https://www.atari-forum.com/viewtopic.php?f=27&t=6924

  1. You can use at least 2 devices without problem. I have 1 CD Burner and 1 HD, both are IDE devices.
  2. You can use 2 ide device on the f030. Remember to set the boot drive as Master, and PC/TOS drive as slave.
  3. You just need a 3-way 44pin IDE cable, one end plug into the motherboard while the 2 other sockets into your IDE devices.

How do I install an IDE SD card in a Falcon

There are a number of different hard drive drivers available (HDDRIVER, ICD, AHDI, PPERA)

  • Jookie's ICD Tutorial - Tutorial is for the SCSI ULTRASATAN, so at point no.7 you need to click 'partition' not 'format'

Can I connect a HDD to both a Falcon & PC?

https://www.atari-forum.com/viewtopic.php?f=27&t=8123
Connecting a PC and Falcon to the same SCSI drive is supposed to be possible. Both controllers and hard disk drivers need to support SCSI Bus Arbitration, and be sure to keep in mind that the PC and Falcon's SCSI interface IDs need to be different.
Thread above details how to do this.

  1. convert TGA/BMP or other sane graphic formats into raw Truecolor data on the Falcon = Escape Paint, it can read the TGA format, but not really correctly, you have just to use Gemviem module and use the TGA Gemviem module and save in .TRP format. It's nearly a raw format.
  2. Converting .XGA or .GOD to something PC readable = Godconv by Evil/DHS.
  3. Imagecopy 4 will convert in 2,3,4,5,6,7,8 & 24 bit depths, I have tried it with JFIF95->IMG and GIF->IMG images.

How to remove the bass from the falcons audio output ?

https://www.atari-forum.com/viewtopic.php?f=27&t=16708
Hardware modifications for getting standard line levels in/out (-10dB), instead of the original microphone in/headphone out. These modifications are described in your Cubase Audio handbook as well, but there is a slight change from that to get the true line levels. All the components are surface mounted resistors and capacitors, so you should NOT do the modifications if you're not absolutely certain that you are able to do it.

REMOVE THE BASSBOOST

  • Change C58, C59 from 100pF to 1000pF
  • Change R123, R130 from 10kohm to 15kohm
  • Change R59, R68 from 100kohm to 4.7kohm
  • Change C95, C90 from 0.033uF to 1kohm resistor

LOWER THE HEADPHONE AMPLIFIER'S GAIN

  • Put a 10kohm resistor between pin 2 of U21 (@ R119) and AGND (@ R111).

LOWER THE INPUT AMPLIFICATION TO -10DB

  • Remove R56, R57, R90, R92, C21, C81
  • Change R66, R87 from 100kohm to 1.8kohm
  • Put a 470pF capacitor in parallel with R67, R88
  • Put a 100pF capacitor in parallel with R66, R87

Floppy Drive subsystem

What floppy drives can you use with a Falcon?

https://www.atari-forum.com/viewtopic.php?f=27&t=7149 https://www.atari-forum.com/viewtopic.php?f=27&t=11687 https://www.atari-forum.com/viewtopic.php?f=27&t=13509
You can connect any pc floppy to F030. Although not everyone will work 100% right out of the box. The problem is HD-floppy detect signal. Without it the floppy will always work as a 720kb driver, or 1.44mb drive. F030 expects it on pin 2 I believe, and most floppys doesn't provide that signal on pin 2, (some provide it on pin 4, or pin 6) if they provide it at all...

Modern floppys often lacks jumpers, atleast visible ones. Sometimes they are hardwired from the factory, sometimes they are hidden under the shielding, so you have to take the floppy apart to move the jumpers around.

Is the Falcon floppy compatible with the ST?

https://www.atari-forum.com/viewtopic.php?f=27&t=10839
If it's a double-density floppy, or a high-density floppy that you've deliberately formatted at double density, then it should read OK - but bear in mind that you're limited by the quality of the disk and the gunk in the drive. If you format to 9 sectors / 80 tracks, a Windows PC should read the disk OK too, and a Linux PC will read most undamaged disks just fine.

Operating Systems

Can I dual boot MINT/MAGIC on the Falcon?

https://www.atari-forum.com/viewtopic.php?f=27&t=7057
Of course you can! And the only thing needed is a boot manager, like xboot or stoop. You just select which files to run at the bootstrap, and you are done. Of course, you need to know which files are required to boot each system.

When I put the machine in 800/608-256 colours, when I copy files between ide and SCSI hd, the machine hangs. Lesson learnt: too much stuff into screen=bus clogging somewhere (and DSP getting hot).
Everything will be fixed with SuperVidel or CTPCI

Some tips on getting cuBase working on Falcon CT60.

https://www.atari-forum.com/viewtopic.php?f=27&t=15928
Some hints:

  1. The EXEP060.PRG - must use the Cubase one.
  2. MROS Driver - had to mix and match in order to get the MIDI-8 to accept midi data, and coupled with the MROS from the original Friend Chip Floppy, and the DRV from the CuBase Folder in the CT Archive... Everythign else seems to crash.
