Anybody know when Atari stopped making STs?

Hi folks. I think I remember an article in ST Format where somebody from Atari UK said they would be reintroducing the 520 STFM. I think it was originally discontinued after the STE had been out for quite some time but my memory is a bit fuzzy. Can anybody remember when Atari stopped making STs or S...

There is no hostility to the ST from me. I like the machine. I don't get some Amiga owners snootiness when it comes to the ST. Jay Miner said the ST was a neat computer. That should end any Amigan argument :)

The blitter.txt in the .lha is a chapter from the Amiga Hardware Reference manual. Please read it as it will help you understand what the Amiga blitter is capable of. :)

If you google hard enough you should be able to find an OCRed version of the official Amiga hardware reference manual. That's the book to read if you want to understand the Amiga. For testing the effect of fetchmode on bitplane contention I'd suggest a simple raster test with the cpu cache off and r...

I think AGA works like this. CPU is 7mhz, 32 bit or 16 bit access at 3 clocks. The slots available for DMA are the same as on the 500/ECS except depending on fetch mode instead of bitplane fetching 1 word it fetches 2 (32 bit fetch mode) or 4 (64 bit fetch mode). I think it is the same for sprites. ...

I'm being unclear again.. First I talked about timing using the blitter then I segued into how much bandwidth was available to the CPU. Apologies. When I mean multiples of three and four I mean CPU cycles. I think from memory the Falcon blitter is a little slower cycle for cycle than the ST one. Clo...

Hi Cyprian_K. Unfortunatly Commodore didn't officially release such timing information on AGA. There is an unnoficial document in Amniga guide format which if I recall correctly was distributed as part of Asm One. This contains some information on the enhanced fetch modes of AGA. On Aminet there's a...

The blitter hasn't changed since ECS but it *is* faster on AGA machines.

With bitplane fetchmode set to max the lost bandwidth is only 2.5k a frame for every plane enabled in low res. Please read the HRM. It'll show I'm right :)

Sorry I wasn't being clear. When I mean a frame I mean one 50th of a second. In order to have a game run at full frame rate it must complete all it's processing in one 50th of a second. I'm talking about the bandwidth available to the blitter in this time. I'm very familiar with the Amiga. If you wa...

Blitter stuff

I can't believe people are still argueing about stuff like this.. but anyway. Here are the figures. Bear in mind I'm talking ECS here and PAL. ST blitter can clear memory at about 80k a Frame. It can copy memory about 40 k a frame. Amiga blitter can clear/copy memory about 70k a frame. This is assum...

The Amiga Chip RAM bus is 32 bit on the 1200 but it only runs at 7 mhz.
The data cache on an 030 doesn't work on chip RAM either. The Falcon is faster than a stock 1200. Both cool machines though :)

New Atari board online

Hi folks. Squid of Squid's Amiga page and rumour mill fame has created a new board on his web site specifically for the Atari ST :D

It can be found here http://www.flyingmice.com/squid/moobunny/atarist/
Enjoy.

FPGA

A new source of hardware would be amazing. A dual Amiga/ST board would be extremely cool. A PDA form factor machine would be out of this world. Wouldn't be hard to beat the current crop of PDAs. Amiga OS with a TCP IP stack would run rings around Palm OS/Wince. Magic on a handheld would rock too. Th...

STE Issue

Hi Simbo I must have been asleep when I read the forum last night!
I just noticed that you're from the west end of Glasgow. So am I :D
I'm in Scotstoun :) Can you recommend a person in Glasgow who repairs STs?

Kind regards,

STE Issue

Hi. Thanks simbo :)

I'll moth ball the machine till I can replace the power supply. I have a spare STE for bits. I'll swap the PSU over in the meantime.

Thanks again.

STE Issue

Hi. Thanks for the reply. :) I'm using a SCART connection currently. I've tried various cables but the problem persists. The symptom is a roll to the left for a spit second followed by the sound of the TV re-syncing. It looks like the ST screen moves to the left a few pixels within its border. I don...

Hi folks. My 16 year old trusty STE seems to have a developed a slight glitch. :( When I turn it on and use it for awhile the video sometimes goes out of sync. I can see the TV re-sync and the display seems to scroll to the left for a split second. Is this a known issue with STEs? The machine was a ...

I have a software only copy for the Amiga. It's not an emulator as such, it's a version of TOS patched to use the Amiga hardware. Hardware banging code won't work :) It's quite fast in mono modes but colour is slow due to the differences in screen layout between the Amiga and ST. I guess there must ...
