Re: stween's build
Without power , do ROMx lines measure short to 5v ?
I don't understand how GLUE gets correct address but does not set any ROMx pins low.. I assume all ROMx from GLUE to the AND gate are connected ?
Do you see any low ROMx lines low on GLUE on FC0000 ?

Re: Slow STFM blitter oddness
how to understand that? e.g. does it mean that in the STfm, every the BLiTTER pass will take additional bus cycle? I don't even remember starting this thread now. But I'd assume due to the slowdowns that a extra bus cycle could be a reason. But not every ST. As stated here https://www.exxosforum.co...

Re: stween's build
So you can decode address zero but not FC00000 , So check address on GLUE itself is correct...
It just seems like you are missing a logic high on the address bus on the GLUE. Either missing pull up, or bad connection.

Re: Atari STE with T0 and e7 spurious interrupt
Ah crap, I measured from the DMA chip for some reason. So IACK does goto the GST. Well its why I shouldn't reply to people in the middle of the night. Its 4am now
So IACK does seem broken on your machine. But do the IPL pins show all high now anyway ?

Re: Atari STE with T0 and e7 spurious interrupt
Ignore my pin numbers , I was looking at the PLCC MFP.

Re: Atari STE with T0 and e7 spurious interrupt
I think you opened a can of worms there.. I tried on 2 STE's and IACK has no connection from the MFP pin 45 to anywhere on the GST

Re: TOS RAM test routine ?
:WTF: Hatari 1.9.0. I set 64 in the cfg file. It refused to show the TTRam bar until I restarted it just. Capture.PNG 1.PNG So putting 10 in TTram size gives me this :shrug: Capture.PNG Does anyone know if there was more " nightly builds" of Hatari 1.9.x ?? I mean it jumps to version 2.0.0...
