Well, the best accelerators for ST/STE are the old classic ones, with cache. Like ICD's AdSpeed and the Mega STE. Well, isn't AdSpeed affected with compatibility problems with IDE? Without cache, memory access is not improved at all, which basically is like replacing your car engine with a faster o...

Thanks to all of you. My application shall be run from the AUTO folder, so the advised methods won't work for me. I think I have found a solution for my problem (not getting the filename, but the underlying problem). Anyway: I do add a cookie but the cookie's value (uint32_t) is too small to take al...

Got a problem retrieving the filename of my own application at runtime. As argv[0] is empty under TOS I tried to get the filename via DTA: DTA myDTA; memcpy(&myDTA, Fgetdta(), sizeof(DTA)); printf(">%s<\n\r", myDTA.d_fname); I'm using Pure C 1.1 and if I enter the debugger via Alt-D I ...

What is "the problem"?

Think about it: what happens when you move the mouse?

Jo is right. You can have more than just one section of Alt.RAM at the same time - see MagnumST. Then the contents of $5A4 is probably not non-ambiguous.

That method works for ST-RAM only, but not for Alt-RAM.

Nope.
It's not a fault. The BIOS checks during VBI processing if a disk change occurred.

Thanx,
so you mean the first byte looks like this

with XXX being the ACSI target number?
But what follows? Standard 10/12Byte SCSI command?

Hi,
is there any documentation around about the ICD extensions for ACSI to send 10byte commands?

thanx, Arne

I'm writing some code to handle a hardware device I am working on. It is mapped into the 68k's address space and my hardware will generate /DTACK if addressed. Now I want to detect it via software i.e. access it and in case of a bus-error handle the exception instead of letting TOS throw two bombs. ...

Merci beaucoup

Can anyone point me to a downloadable archive of the INSJAR program (http://toshyp.atari.org/en/003007.html#Cookie_2C_20INSJ)that installs a cookie jar and fills it with some standard cookies?

I really dislike to see first 5 RECENT TOPICS polluted with FPGA stuff. I occasionally open atari-forum.com just to see 5 recent topic and almost always I see 5 topics about FPGA in "recent topics". And I am not interested in FPGA at all. There is no need to prohibit anything, just move t...

Seems to be an interface for this bus: https://en.wikipedia.org/wiki/Europe_Card_Bus IIRC it was a DIY project of the German c't magazine. At least the small yellow PCB at the left hand end of the flat-ribbon cable is a ROM-Port buffer. Useful to protect the ST and for extending the port's signals.

Do you refer to something like this: http://info-coach.fr/atari/documents/myFAQ.php Section Falcon video?

I posted the GAL code here: http://www.atari-forum.com/viewtopic.php?t=30291&p=315382#p315382

3meg isn't a supported RAM config on the ST, you probably have 2.5meg :) You are not up-to-date. 3MB IS possible. I had it one of mine, too. how does that work ? 2 meg add on card with 1 meg onboard ? Exactly. 2MB bank must be bank #1. With some TTL (I used a GAL) /RAS and /CAS lines are generated ...

(double post - please delete)

Back in the day 2.5Mb was quite common on STFs. With a GAL or two 74 TTL you could resurrect the last 512KB again. At least TOS 2.06 counted up to 3072KB but I think that TOS 1.xx supported 3MB, too. Wasn't 4 meg the max on ST models ? In general: yes. Besides the well known Alt.RAM expansion that ...

I remember having a TT-RAM-card in my TT where I would have to manually add jumpers to these pins as the SIMMs I had left all these pins floating even though they were 32Mb SIMMs. Might that be an aixTT? MagnumTT has additional jumpers/pull-ups in case the PD pins are not set (correctly). I guess t...

"T0 MFP Timer" Service Manual says that's a problem with the MFP timer(s). Or is protocol here to just remove/replace the 68901 MFP? NO. Protocol is to find the error. Take a scope, the schematics and check the clocks(2.xMHz and 4MHz), the /CS line and see if /DTACK is activated shortly a...

Still have some available in my shop.
