Re: WIFI for all ataris over serial!

I have no intention of doing so because I fail to see the benefit. When using the STinG firmware, you don't need the special applications (like wifiset and wgetst) anymore.

Re: Atari Test Cart

Also note that with the PCB that you ordered you cannot simply exchange the EPROMs. The schematic and layout don't fit for 27C256 EPROMs. So the thing is basically useless, I'm afraid.

Re: Atari Test Cart

I bought mine from https://easyeda.com/nplanel/Atari_ST_Cartridge-10329107c6f942e78c3bfcc8d2efa9a8 wich tells you that you need 27C128 roms. Anyway, each dump is 32 kB. There is plenty of room in a 128 kB rom for 32 kB. Maybe you should have looked at the datasheet instead. A 27C128 EPROM is 128 k ...

Re: RAM upgrade

Suggestion: When using YAARTTT.TOS (not(!) YAART.TOS as you would usually do on an ST) you select a "hidden" option by pressing "M" at the prompt. That way you can test address ranges that are not recognized by TOS. In this case, if you enter the range from 0x200000 to 0x3FFFFF y...

PS: You can see how the buffer cleans up the signal in the attached scope screen shot -- measured on the 1040STE. Yellow trace is the mono output from the Shifter. Notice the high amount of noise plus one very visible ripple due to GND/Vcc bounce. Blue trace is the output from my buffer board: much ...

Re: Faint vertical gray lines in STE/MSTE in high-res - Am I the only one?

On the 1040STE the results were (only) partly promising. The lines were visibly reduced, but contrary to my MegaSTE they didn't fully vanish. As requested on FB, I want to document my findings, though, while I think of solutions for the 1040STE. After a lot of measuring, I've come to the conclusion ...

Re: Falcon TOS EPROM?

Well, if you move TOS out of romspace, it has to be relocated to the new adress space it is using, So the TOStoRAM software needs a relocation table to adjust all direct rom space adresses to the new ones. I'm not sure if there is relocating tables in TOS, or the creator of the software has to buil...
