But isn't that the AT-Speed C16? Does it have socket for FPU? The AT-Speed is a simpler one and it doesn't look like it is has clock on the board. So it probably use the system clock.

Very few games check for disk swap automatically. You most likely need to press space bar or fire button to continue. In GEM when you have a window open with A: just press ESC on keyboard to refresh and reread the floppy content.

How are you going to mount it? The Mega STe or STe don't have a 64 pin DIL sockret. It is a plcc chip.

Or just get an Eiffel interface and use a PS/2 mouse and keyboard.

Older came with DD, newer with HD. Same with TT. However the Mega STe came pre pepared for HD if you only got DD. It's just a GAL chip and a HD drive I think. EDIT: WD1772 needs changing to AJAX.

This is pretty good as well: Part 1, Part 2.

Here you go.

You won't get double speed with 16Mhz. It's like 25%. Bitter doesn't do that much different. I would say a HDD. UltraSatan or a IDE interface internally . ParCp-USB or NetUSBee for transfer. Can you solder?

Nope, a blitter won't be enough.

Have you hold your finger on all the chips? Any of them getting extremely hot? Warm is okey, you should be able to hold your finger on them. If it is burning it is a sign that is is shorting. MMU or perhaps memory chips hot? Otherwise you need to start checking if you got clock signal on all chips and if you got signal on address lines and data lines. If anything seems strange or a missing signal. Or checking cold solder joint or cracks. Anything suspicious really. When does it start bombing by the way? At boot screen? Directly after power on? Does it have time to start accessing the floppy drive? When booting with diag cart in you could connect to another computer via a null modem cable and see if anything appears on the other computer with a communication program on it. 9600 baud 8N1 (8 bit char, No parity, 1 stop bit). RAM seems to look as they do on factory Mega 1. I got 256 in my Mega 1 as well.

Nope. Falcon has SCSI in the back though. But no STe has it from factory. Maybe someone hacked one in? Do you have YT link? I'm really curious now.

Or was it a Mega STe?

Nope. Normal STe didn't have SCSI. But it have ACSI. But you can't connect a SCSI HDD directly to that. You need a adapter for it.

I read this at https://forum.atari-home.de/ written by Dal on facebook: Later:

The decoupling capacitors would provide a more stable feed and eliminate spikes. But it isn't necessary. Tried changing the 74LS244 and 74LS373? Otherwise try put your finger and feel if any chip is hotter then the others.

Yes, you already made a topic about this some time ago:

A rom is 192Kbyte on the ST, or TOS 1.00-TOS 1.04 is. So 27C256/29C256 or similar work. 256Kbit/8 = 32 Kbyte and 6 of them = 192 Kbyte. I think 150ns or faster is fine. Can't remember what Atari put in. I say get 100ns or faster. eBay... Well, most of the time it is fine. To be safe, buy one or two extra. Just verify when you burn them that they burnt correctly. It's a gamble. EDIT: Apparently 200ns is fine and 150ns or faster chip is prefer.

The programming tool is called xgpro. eprom depends on which Atari you are planning to upgrade. Diffrent TOS version has different sizes and demands different eprom. Normal STfm for example can use 6 or 2 eprom configuration. 6 is easier since the eprom just fits. 2 eprom you need to hardware hack a bit to get them to work since the eprom is 32 pin and the slots is 28 pins. There is no 28 pin of that memory size that is a direct fit. Depending of what you choose and what is fitted already you might have to change some solder blobs on the main board. And fitting a chip in certain cases. STE often needs to change some 0 ohms resistors, other then that rather simple. Then you can choose from eprom or eeprom chips. The eprom is a bit cheaper but needs UV light (sun or gadget) to be erased if you want to program it again. eeprom is electrically erasable memory and you don't need additional hardware. So what Atari do you got and have you open it up and looked what configuration it has now? Pics please! EDIT: Is it your Mega 2 you want to upgrade?

I actually found a YT-video when browsing for other things just now. The guy developing HxC is running DSOTS on a STe when demonstrating on-screen-display capability on gotek. You can see the case open and the two ROM under the diskdrive clearly showing a STe.

I don't think it's a STe thing. It's a timing issue when you run it on a ntsc machine.

Yep. I can confirm that also. Tried on Swedish TOS 2.06 with Swedish keyboard (QWERTY top left corner) and it behaves as a AZERTY in FF file selector.

Yes, but if a french keyboard with a UK TOS it will be this problem. He haven't proven if indeed it is a QWERTY keyboard or the keys have been moved around from a AZERTY to become a UK keyboard we will have no problem. It is in fact as you say dumb switches. It is really strange. UK TOS with french keyboard bought in Australia. Yeah, sounds like it have to be a UK QWERTY keyboard.
