Re: STe - Bad DMA Chip

For the record. my STE has the 'good' DMA IC and standard CPU and has always 'just worked' both with an ICD based HDD unit (before that broke down with a fault on the ICD host adaptor) and with an UltraSatan, which is what I bought to replace it. Between the two (A special IC produced only for a cer...

Re: STe - Bad DMA Chip

I don't want to rock the boat, but what happens when you combine a 'Good' DMA IC with a 'Good' CMOS CPU? Anyone tried that?

Re: ATARI STE 1MEG NOT WORKING!

I take it you are saying it's dead WITHOUT the Ultrasatan connected now? One possibility is that if any of the parts of the system (STE, Ultrasatan, Monitor) were already powered at the moment you connected them together you may unfortunately have damaged something - there is an unwritten rule that ...

Re: Atari ST hardware problem

i bought a new shifter ic and will wait for it first before checking the rams For reference, unless you happen to be a playboy millionaire, always try the things you can try which don't cost any money first, such as removing and re-seating the socketed ICs.

Re: Atari ST hardware problem

Can't help you specifically with that fault but like mlynn1974 above I notice the socketed RAM ICs are a different brand to the original ones still fitted directly in the board. What this says to me is that someone diagnosed a RAM fault and started to change RAM ICs until the fault was fixed - at wh...

Re: 520STFM, no picture through RGB SCART

There's a recess at the opposite side of the monitor socket into which the odd pin out (pin 13) will comfortably fit if you present the plug to the socket upside down. With the exception of pin 13, the pin layout of the 12 other pins is a perfectly symmetrical rectangle which looks exactly the same ...

Re: Reverse engineering of some ICD Link adapter

OK, I didn't lay hands on my broken ICD interface yet but from DrCoolZic's Pictures and the knowledge that mine did not have a battery backed clock, I can say that mine is some version of the AdSCSI. It looks very like the one in the middle of DrCoolZic's second picture a couple of posts ago. Unfort...

Re: Reverse engineering of some ICD Link adapter

While finding out how to best add initiator ID capability to my ICD AdSCSI plus ( not ICD Link!), I reverse-engineered one or two of the PALs.

Re: Reverse engineering of some ICD Link adapter

That's a pity, as I have a broken ICD host adaptor which I am fairly certain has a damaged GAL / PAL in it. All the standard logic ICs have been lifted and tested in a dedicated TTL chip tester.

Re: 520STFM, no picture through RGB SCART

Long shot, but are you sure you don't just have the 13-way monitor plug plugged into the STFM's monitor socket upside down? It is surprisingly easy to do that despite the presence of the one offset pin and the usual symptom is no picture and a loud buzz through the sound, the latter caused by the fa...

Re: Trying to find the name of an adventure game

I think the limitation of a USB connected floppy drive is that it can usually only handle 'standard' PC track and sector formats, whereas with an integral drive, software can directly manipulate the floppy controller for the creation of / recreation of non standard formats.

Re: Trying to find the name of an adventure game

Maybe we should say that a file which contains an Atari disc 'image' typically has the extension .ST, although other formats exist. If a Linux PC with a motherboard connected floppy drive is available, then the Linux 'DD' command can be used to write an .ST image to a real floppy. if a Windows PC, t...

So I played Price of Magik for quite a while last night (Under Hatari V2, where it runs fine) and encountered two aggressive enemies, a giant slug and a walking skeleton. Apart from fighting the slug I can imagine that the other way to deal with the slug must be to use salt, a traditional anti-slug ...

Re: Trying to find the name of an adventure game

Not a bad looking game, especially for a tie-in, where they tended to spend too much on the rights and not enough on the game. But I've been right through the list of spells (recipes) in a walkthrough for Elvira and I don't see eyebright mentioned there.

If an ST text adventure with really good location graphics made a big impression on you, chances are it was one of the ones by British producers Magnetic Scrolls. But which one?

Notice I didn't say 'trainer', because that normally implies infinite time / infinite ammo / infinite fuel / infinite lives.

Re: Hatari MIDI support

It would be interesting to see how accurate the timing can be on a Pi running Linux compared to an Atari. Unfortunately there are no professional Linux sequencers, so you're always better off with an Atari. My guess without trying it would be: Atari 1, Linux 0, simply because the Atari OS (that I a...
