PAK68/3 floppy not working
Re: PAK68/3 floppy not working
As an example, one of my Mega has 120ns ram and will not reliably boot the pak at all. The SOP ram I have is 70ns and runs fine.
If it ain't broke, test it to Destruction.

Re: PAK68/3 floppy not working
I saw this comment in the PAK manual:
Anyone have this buffer board or schematic for it?

Re: PAK68/3 floppy not working
Sounds like he talking about the STE buffer chips.. schematics are freely available for the STE machine. But I would suggest doing the current DMA fixes before buffering...TheNameOfTheGame wrote: ↑Tue Mar 31, 2020 5:04 pm I saw this comment in the PAK manual:

Just because a lot of people agree on something, doesn't make it a fact. ~exxos ~

Re: PAK68/3 floppy not working
About the memory thing... I'm pretty sure I had 120 ns chip on my STacy when I
first started installing my Pak board. But I actually did "RTFM", at least during
the installation, so I caught that part about having problems with slower
RAM.
I switched it out for some boards I got from Brad at Best Electronics that were
80 ns chips.
Hadn't had any problems relating to slow memory that I know of...

Re: PAK68/3 floppy not working
I agree, a mega with 120ns ram would give me memory test issues but when changed to 70ns worked fine.
If it ain't broke, test it to Destruction.
Re: PAK68/3 floppy not working
Its odd though as the MMU controls RAM and speed of RAM shouldn't matter could just be down to bus loading or something ,

Re: PAK68/3 floppy not working
Anyone heard from pakman? The last time he replied to any of my questions was over a year ago. I hope everything is ok.

Isn't he part of the lightning team ?TheNameOfTheGame wrote: ↑Fri Feb 12, 2021 2:44 am Anyone heard from pakman? The last time he replied to any of my questions was over a year ago. I hope everything is ok.
He's not logged in here since July 2019.

Re: PAK68/3 floppy not working
I don't know really. Is there a way to contact him through that project? I've been trying with the German Atari forum.
