Re: A little bit of 8 Bit: 65XE upgrade to 128k RAM

Hi, Sorry to resurrect an old post but I'm curious on which 65XE motherboard this expansion works? I'm particularly puzzled by the connection between GAL pin 7 (PB6) and PIA pin 16 (PB6) as on my mother board that PIA pin isn't connected to anything. So what is that connection supposed to do? I just...

Re: A little bit of 8 Bit: 65XE upgrade to 128k RAM

Hi, sorry beeing late to the party. I read you already fixed the problem ;) As another update - well it wasn't the +5v that was causing the problem. It was the Mitsumi 56-3217 keyboard mylar that apparently decided it had enough of being pulled in and out of the slot. The joys of working with >30 ye...

Wanted: DELA Epromdisk firmware and software

Hi! I got this expansion, a "DELA Romdisk" for the Atari ST - unfortunately without Eproms. Some investigations shows me, that the both Eproms on the top (2x 27256) contains the controlling software and "driver" for drive "c" (little C), and the other 8 sockets can be filled with Eproms containing t...

Re: WANTED COSMOSEX

Hi Jookie, currently I'm not making devices as I'm somehow burned out from everything I did in the last few years... I'm considering to leave the making of devices to someone else, and the schematics and pcbs will be public soon. More info later. Real life, family and health ALWAYS first! Please tak...

This is the current schematic for the new STF design.
This still needs checking against the STFM schematic for mistakes.
Looks very cool. And I see, you´re also a friend of Eagle :)

Re: LIQUID RETROBRIGHT TEST ON MOUSE

Hi, Top part of the mouse socked in liquid peroxide. Left in sun light all day. I have this Retrobright stuff since years on my "to do" list, but never tried until now. Question: Do you leave the mouse all the time IN the fluid? And did you try it also with bigger parts? I saw ready-to-use "cream" f...

Re: Scope recommendation

Hi, Rigol DS1052E (50 MHz) - 321 € new (Amazon) Rigol DS1102E (100 MHz) - 339 € new (Amazon) Hantek DSO5102B (100 MHz) - 250€ new (Amazon) I would strongly recommend the Rigol DS1102E. The price difference between the "50 MHz" and "100 MHz" version are too less, and newer firmware versions prevent y...

Re: unknown ST Overscan circuit with 7400

Hi, For use noobs to extra resolutions, if there are software solutions, why is the hardware needed ? IMHO the hardware is only needed to enable the MMU to scan more than 32000 bytes video memory AND prevent the GLUE vom generating a bus error (2 bombs). I don´t know if we´re talking about the same ...
