Re: BAD DMA - Myth or fact ?

I have 1 520 STE, and 2 1040 STE. The 520 and the 1st 1040 were made in 1989, 1990. The 3rd machine, a 1040 STE, was made in 1991, and is the only one working correctly straight out of box with my ultrasatan. The difference hardware wise, is that the one from 1989 and 1990 have the beta motherboard...

Re: new game (need loop fix)

I'd recommend using a state machine for a game
You should have three sub states for each state, init, logic, and exit.
You then call a reentrant function repeatedly and change states when required. The game runs as a tick until the state changes.

Re: BAD DMA - Myth or fact ?

The press at the time said it was limited to 1040 STe machines. I had my PSU reconditioned on my 520STE.

Re: BAD DMA - Myth or fact ?

to give you an answer, i would say that all the STE made in 1989,1990 are plagued with this problem. The STE machines made from 1991 don't have the problem. Those models have a finalised hardware (read : with no patches made at the factory). Yet I have a 1989 model which is fine with ultrasatan and...

Re: Power Cables and Requirements for U.K. 520STFM in the U.S.?

Yes. I did this by accident with a yankee on in the UK. I was lucky it just blew the fuse. Simbo brought it back to life. It works fine with a step down transformer.

Re: DIY Fpu Unit for STFM - possible?

OK, you're mixing two thing up, I think. First, F-line instructions are indeed used for FPU on CPUs that have a coprocessor interface, starting with the 68020. So on the TT -- when equipped with a FPU -- floating point math will be done via F-line instructions. However, the 68000 doesn't have a cop...

Re: Enchanted Land parallax scroll

Sometimes the code is so optimized it won't change anything, like in Wings of Death in which the blitter option does nothing except messing with the player inputs :) Wings of death is frame locked at 3 vbl like Lethal Xcess. Even at 60 hz. Try the fast 25 fps L.E cheat with and without a blitter. O...

I had a copy of ranarama with my original STe explorer pack. Amazingly Atari managed to bundle a game which didn't work with the Ste!

Re: STE horizontal hardware scroll

What's the CPU cost of saving/restoring registers too? What's the CPU cost of 200 timer b interrupts that just RTE? I did a dister with timer b and hardscroll but it must have been 20 years or so ago :D I have a figure in mind of around 20% CPU for that.

Re: STE horizontal hardware scroll

The issue is the maximum number of words that can be skipped on the end of a line. :) If you can reset the scroll and address every line it doesn't matter. You can "skip" as many words as you like :D

Hi. I'm sure I posted an attachment of the TT desktop to the forum as a prg file for general STs.
I'm looking to see if I can get it working on my ST but I can't find it. If someone has it, can they please upload it?

Re: We redesign the STE

OK. So point us at a few recent games released on the Arch. Say within the last 5 years. We had a BBC in our house. I turned my nose up at it and used a Spectrum instead. I much preferred the speccy. The Spectrum scene is still amazing even now. Much healthier than the Atari and Amiga scenes.

True for the arm64 port yes. So far. Who knows the future ? There is an active community of talented coders, let's see what they will do.

Re: We redesign the STE

Arm32 is dead now. There's no arm64 port of RiscOS which is the future. There's no high end hardware. It's a hobby platform like the Amiga and the ST. At least the ST has EmuTOS and the Amiga has Aros. There's no open source equivalent on the archimedes. I know all about the mess behind the RiscOS &...

Re: We redesign the STE

Dude. RiscOS is dead as a dodo. I'm sorry, if you think RiscOS is a healthy software ecosystem you're deluded. The ST and Amiga scene is way more vibrant. You need to face reality. It may be fun as a retro platform but it is not commercial.

Re: We redesign the STE

The problem with the STE was that it didn't offer an incentive to existing ST users to upgrade. Most of the features were gaming oriented. If you were a serious user the SIMM slots and blitter would be useful. The DMA audio might be useful. It's not enough reason to upgrade. I'd have supported more ...
