Does anyone have a clonecd dump of the V2.1 L31 OS CD? , I haven't had much luck with bin/cues.

Thanks, I have made some progress but still having some issues

1.) Drive Mappings



I think have the drive mappings setup correctly but here is a screenshot of setup.exe just in case i have something setup incorrectly

2.) Booting



Booting from the HDD image looks to have worked as mapped drives all appear and TownsOS loads with G: showing the following installed files

I didn't take a screenshot unfortunately (though happy too if needed),  however if i click on any drive like the i: (games) the window is empty.  Nothing is showing.

If i close g: and reopen g: the files have disappeared!  i am at a total loss as to what might be the issue. 

I am speculate the files are present in g: at least as the system boots.  But can't work out why i can't see any files/icons

Hookay so bit of an update ,
I managed to actually get it to read burnt discs , so what I ended up doing was to use my Windows 98 retro PC to burn some CD's at 4x speed with an old pioneer burner from circa 2000-2003ish and so it looks like I wont need to adjust anything. I'm pretty chuffed right now.

If you don't want slow memory past 2MB, you need a RAM expansion that goes in the slot near the CPU. These only go up to 8MB (6MB module + 2 onboard) but in practice that's fine because nothing actually needs more than this.

Very interesting, thanks for the info!

By the way, you actually do need more than 8MB if you want to load certain games from this HDD image (e.g., Valis II) due to the extra RAM they consume with virtual floppy mounting. Granted, those are just a handful of titles.

I have too many programmers. I didn't feel like buying another programmer (USBTinyISP) to program the DFO programmer, so it could program DFO's. 

I spend all evening trying to program the Atmega48A on the DFO programmer (it has a proper ICSP port) But nothing I tried was able to communicate to the Atmega48A. I tried Arduino_as_ISP on an Arduino Nano, AVR USBasp and lastly avrdude on a Raspberry PI.  None wanted to communicate. But I was able to communicate to the Atmega8 on the AVR USBasp.

Given an Atmega48A is pin compatible with an Atmega8 (found on my AVR USBasp), I swapped microcontrollers and was able to easily program the Atmega48A installed on the AVR USBasp through AVRDUDESS, using the Arduino Nano as the ISP.  The only difference I noticed is that pin 14 (/SS) is held to pin 29 (/RESET) and not floating like on the DFO programmer.

The Atmega48A detected fine, programmed, and now CDCE9XX is able to detect the DFO programmer.

Hope this helps someone in the future.

Hi, i would like to get some help to get a og grey x68 running (brough as junk).
The computer show some sign of life: when i press the psu buttons (behind), the power led go red and when i press the power buttons the power led go green and the high reso led go red.

I connect the x68 with a vga adapter to a crt monitor who detect something but black screen, same with an upscaller (sync on something but no picture).
I just recaped all the board (not the psu and the floppy drive) and changed the cristal near the battery. The second floppy drive as the edge connector broken (the one with the floppy ribbon).

Is there something i can verify or test?

I got it working finally in 2 button mode.  I updated the 2.4g receiver to 3.02 firmware.  They don't list the dongle firmware on their website in any obvious place.  On a facebook forum somebody told me what version firmware they were using and when I saw their was a dongle firmware I look into it.  I found an old post online mentioning you can open the dongle with a torxs bit and find a micro usb port.  Now I'm running firmware 2.06 on the controller and 3.02 on the usb receiver.  Like I said I couldn't find this on the website and it probably wasn't meant to be user serviceable.  Hopefully this helps somebody one day because it drove me crazy.

Now it works fine using my 2 button dongle built without the switch.

Next week I'll try the blue retro bluetooth reciever and report back.

Looking at cz-600 schematics (i never found the schematics for the ACE) the battery is re-charged by VCC2, the +5VSB line, so it's charged even when red led is on

My ACE battery has run out of charge. I know I should consider using something else than the barrel battery, but at least it is a "recent" one (7 years old or something), that replaced the original. And I know I will have to set the SRAM settings again, fortunately I have a system disk.

My question: will the battery charge again simply by hooking the machine up to a power socket and keeping it in "soft off (red LED)" mode, or does it only charge when fully powered on (green LED)? I'm a bit hesitant keeping the machine fully powered on for a longer period of time.

Right , well so how do Gain and Offset help , do they focus the beam more?
