Wanted: Atari STE

In the UK. Just the motherboard would do too, but working condition.

Re: USB HID interface

I've bought this board with the intention of doing something for the IKBD interface. The nice thing about this board, it has dual USB ports for Keyboard and Mouse. But also a bunch of I/O for joystick emulation too. It has a serial port for direct interface onto the IKBD interface. I think it has a...

Re: New board: MonSTer

Currently have 10 MegaSTE boards, and 10 ST/MegaST boards half finished for those folks still interested.

I'll be getting some of these finished this Friday.

Re: Mega STe/MonSTer blitter problem

The BLT pin is connected to ground via a pull down 10k resistor near the pins on the reverse side of the board. The default OFF position. When you add a jumper, it connects the BLT pin to 3.3v. To tell the CPLD that you have wired up the pins on the other blitter connections. Now the BLITTER would b...

Re: Mega STe/MonSTer blitter problem

I'm convinced it's on the XC95144XL. If your soldering skills are up to it then I'd reflow around those pins.

And if not, I guess you can send it back and I'll take a look.

Re: Mega STe/MonSTer blitter problem

Can you check the top right corner of the XC95144XL chip, and the two pins on the far right.

The last on the right is 3.3v, and the one before it is the connection to the blitter pin. Check if you can spot any bridge between those pins.

Re: New board: MonSTer

When the images match, it's likely to not cause a problem because the data is the same.

It's when you've flashed a modified TOS that problems will occur.

You could put a switch on the OE/CE pin on the originals ROMs and leave them in though for when you'd need a failsafe.

Re: Atari STBook issue with power circuit - L1003 ?

Size and shape doesn't follow at all once you start looking at them.

I've opted for a 200mA though.

Mmm. Seems as though there's a mA rating with them too. Doesn't seem to mention in dev-docs.

Atari STBook issue with power circuit - L1003 ?

Anyone know what L1003 is on the STBook ?

Looks like an inductor, that has 9147 written on it. Seems as though the one I've got is blown.

Looking for a spec/alternative.

If you still haven't had a reply it's likely I've not got you down for a board, so you'll need to PM me directly. At this point it's likely people will end up on a pre-order li...

Sounds like the out port of the unicorn may have a bad solder joint then. Might want to check that.

Re: PCI for the Atari range

You've got to ask yourself a question of why you need PCI ?

Is it just graphics for a bigger TOS screen ?

Is there anything you require for the Atari that's now not available via USB ? Sure, maybe drivers haven't been written, but they could be.

I've had a few PMs over the last few hours. Bear with me folks. They take time to solder and test. And the boards I mentioned above, are bare unsoldered boards. I've just tested 1 x STE, and I'm half-way through a MegaSTE board. I think I might not be able to provide the Interrupt cables for the IDE...
