exxos's Atari, Amiga & retro forum

So: Hello All ;-)

Bought my first Atari ST+ in the '80s.
When the Mega ST was introduced I had to have one - I am still using it today
Member of an Atari ST club, where I spent lots of time
With other members we managed to build a small print for automatically switch to HD floppy and back
Also some screen / video mod's: Overscan, BigScreen.
Bought myself PixelWonder and a VOFA card (via Frank Lukas)
After many years of doing very little with my Atari, I lately got (via YouTube) interested in accelerator cards from Stephen Leary
So I bought a TF534, which only boots into EmuTOS 1.1.1, but I have no luck in using floppies and / or HD's ;-(
I have read Agranlund's threads about installing a TF534 in a Atari ST
I did already follow EXXOS forum as guest, and now I would like to become a full member
In that way I can post questions to get my problems fixed (I hope ;-)

Welcome to the forum!

I'd be interested to hear more about the overscan/bigscreen mods for the STs

I've got a TF536 in one of my systems (an Exxos H4 Mongrel board) & have that working with an IDE card (an Exxos TRUDIE board using a CF card for the storage) with the excellent HD Driver & that boots & accesses the hard drive OK.

I did have problems with the floppy on that originally - I can't honestly remember if I resolved them or not...and I've taken the TF536 out for now to help diagnose an issue accessing the floppy on an Exxos H5 Phoenix board.
There seem to be a lot of cache issues and possible problems with where the floppy buffers are stored, so it may be solvable with just some reading on the forum & asking a few questions as you go.

If you are still struggling with it, let us know & I will try to re-fit the TF536 & check the floppy.

Hi.
I am from the UK but in the summer we visited the Home Computer Museum in Helmond. It was excellent!

Would love something like that nearby when I retire, I would help out all week 🙂

:welcomewave: fellow Dutch guy. I’ve started with a 520ST in the 80’s. Some time ago, I found a Mega ST4 on Marktplaats for a reasonable price, so this my project machine. Mods done: High density disk drive with autoswitch, Lightning ST with 2gb CF card, USB ports and TOS 2.06.
