Re: 1040 STFM no floppy icons / Desktop appears immediately

Then I suggest to measure the DS0 line. There is just an inductor between PSG's DS0 out and the ribbon cable. I have seen defective inductors, but not in signal lines. A multimeter should be fast enough for this purpose.
Have you checked the swapped parts in another ST that they run correctly?

Re: 1040 STFM no floppy icons / Desktop appears immediately

Get schematics, and check DriveSelect0 and SideSelect coming from the PSG.
Your drive is jumpered for Drive0?
You use TOS 1.0x?

Re: Scooter-PCB to Gerber?

There is either a plotter or printer driver PRG included. But be aware: ScooterPCB (Atari) macro's drill holes are probably NOT correct (confirmed by Mr.Kahlert). Second: ScooterPCB (Atari) can only plot RS-274-D. This is obsolete and almost no PCB manufacturer accepts it! Use the Windows version of...

In general: yes, all ST chipsets (260,520,1040,MegaST, STacey) are interchangeable. IIRC there do exist 80pin SMD MMU and/or Glue. But these are soldered to the PCB.
But better do not mix IMP and non-IMP manufactured ASICs.

Re: Atari TT boots to desktop but black screen with diagnostic cartridge plugged in

If you've got a 2MB ST-RAM card added then remove it and try again with the diag cart. Your TT might have the cartridge port fuse burned. If this is the case when you plug the cartridge it pulls all lines to LOW and would probably give you the black screen you see. Anyway: I've seen the inductor nex...

Re: TT Fast ram compatibility?

But you can enable or disable nibble/burst mode with a jumper. In fact nibble/burst mode doesn't even work with my stock 4x1mb dimms. That's true. Is your card a 4MB card that is capable of taking four 4MB SIMMs (CA401058) or is it a 4MB-only card (CA400312)? You can upgrade a CA400312 board to 16M...

Bad luck... this narrows it down to the SIMM mod.
Don't forget to either deactivate the onboard DRAM or remove it.

I used a GAL instead of 74xx and it worked without problems in a 1040STFM with 2.06.

STing Driver coding

Folks,
I got a question regarding on how-to program a driver for STing.
I think (!) that the driver which accesses the hardware is this STX file. Right or wrong?
Is there a How-To with demo code that driver?

So the problem on my TT was its drained battery i.e. the .C file was always newer than the compiled/linked .TTP.
