Re: 260ST barn find

Just a small update - I didn't sort out much else but this one: The MC1377P video encoder IC used on the Commodore A520 needs an 4.43Mhz sine (or square, as seen in the original schematic of the A520) wave on pin 17 for the color subcarrier. The original design was using a clock provided by the Amig...

Re: 260ST barn find

XadUndisk on Amiga handles both ST and MSA images. Thanks for pointing this out. I prepared my Miggy and will try to write the culprit images as soon as I got this Atari up and running. ~ My makeshift Power Supply is finished. I just butchered an Amiga 500 PSU and soldered an Atari PSU plug to the ...

Re: 260ST barn find

Nah, all I have and know is ADF2DISK, I didn't try that with non-Amiga formats yet.

Re: 260ST barn find

You have a memory upgrade there! :) Not fully populated either. That's great news (as I alluded to over at Reddit). edit: Yes. you got that right. The Atari talks Shugart, just over 14 pins in that external connector instead of 34. It's just wiring. http://info-coach.fr/atari/hardware/interfaces.ph...

Re: 260ST barn find

Eew I'm glad I didn't just power this up before opening. I don't really wanna know what that fluffy stuff is. Also, this MMU PCB popped right off the socket when I touched it: https://i.imgur.com/tZp188M.jpg It looks like this machine is populated with TOS1.4 roms, according to the stickers: https:/...

Re: 260ST barn find

Great news, thank you. So do I interpret that correct that the external floppy case has no own logic components aside from the floppy itself? Concerning my building abilities... I'm certainly no master, but I learnt proper soldering techniques in my job training, and made the occational hardware mod...

260ST barn find

Hi folks. I'm new around here and to everything Atari in general. I was a Commodore kid back in the days so I've got NO prior knowlegde whatsoever, so please bear with me when I seem to ask stupid questions. I already read up on some topics, but still need confirmation on some things. I only know th...
