Re: STacy RAM Board?

Alan, any way to make the Eiffel work with the original STacy keyboard? Also, with the 68000 covered, you can't use an accelerator board, or am I looking at that wrong? Thanks! You could read the existing STacy keyboard rather than a PS2 one by modifying the Eiffel microcontroller code, so basicall...

Re: STacy RAM Board?

Thanks for the pics, is good to see a shot of Alanh's board. I was going to ask if it overlapped the main pcb or extended outward as I'll be lacking space in the rack case. I got my stacy pcb's from ebay funnily enough. Atarifreakz I think was the seller. Got some nice TT bits from him at a bargain ...

Re: STacy RAM Board?

Right, Alan's does replace the RAM, but the RAM only. So if you're one of those people (like me) who likes their STacy in the original case, then you're kinda out of luck. You can't just ditch all the other stuff that works off the original RAM board. Ah, is it all on one sub board, the rom / ram /...

Re: STacy RAM Board?

It would be nice if someone would make a memory board for the STacy that uses SIMMs, and still gives the keyboard, mouse/joystick, TOS options, etc... The original STacy RAM boards are getting old. I had to go through a couple, just to find one that was fully working to get 4megs in my modified STa...

There was me thinking I was being original. :lol:

Out of interest how much for the Eiffel / ROM board as well? I may take the lazy option and concentrate on the expansion side of things instead.

Re: STacy RAM Board?

No worries if you have it covered. But I use an Eiffel on my recased stacy, as well as a TOS 2.06 board with my IDE adapter. I have all these available if you need any help. Cheers, I'll bare that in mind! What have you recased the stacy in? Another portable form? I've had a couple of stacy motherb...

Re: STacy RAM Board?

£15 inc p&p would be fine. What are you doing about keyboard & mouse and TOS ? Sounds good! I'll be in touch about that. :D Keyboard and mouse will be via a custom Eiffel board which will also include the tos rom. I've been pondering having soft power controlled via the keyboard controller and an a...

STacy RAM Board?

I'm going to rack mount a stacy motherboard I have and need to make a ram board for it as I just have the main board and none of the sub boards. I'm going to make a board which accepts a 72pin SIMM to give it 4mb of ram. Is this something which is of any intest to existing stacy owners? I thought I'...

Re: ST HDMI Out

It can't work in mono mode as that doesn't work over scart. Yeah, it can work with mono. HDMI is not scart. You have to understand I take the video out directly from the shifter (4 bit RGB & single bit mono) and construct an HDMI data stream from this information. I output in colour modes at 720x57...

Re: ST HDMI Out

if somehow it wasn't compatible, you could always make it switched, more soldering perhaps... but it's just an output jump board not a gfx card as such like VBXE There's no switching required, this just outputs the same signal that goes to the monitor port to an HDMI port. So you could run an Atari...

Re: ST HDMI Out

It'll run with any STF / STE / Mega / Stacy (and Jaguar, Amiga, Amstrad CPC plus, GX4000 and lots more machines) as they all output video using 1 pin per bit of the colour data. Unfortunately it wont work with the Atari TT as it has D2A converters inside the shifter and outputs RGB directly as analo...

Re: New ST hardware projects interesting to develop?

Yep, the HDMI adapter is still in the works, just progressing very slowly at the moment! I've got a prototype PCB layout done and am just getting around to getting a small batch of PCB's made in China, as it works out cheaper and easier than trying to make them myself.

Well, I've made a bit more progress tonight. I have the packet encoder generating the CRC for the AVIInfoFrame packet once per frame, which is then output in the HDMI stream.

Re: ST HDMI Out

You'll still need to make some sort of "frame start" signal out of Hsync and Vsync. If you don't, you'll be misaligned, and even if you do get aligned, it will drift. i was using Hsync to count lines, and just ran my output 2 scanlines behind the ST. (tho the overscan Hysnc oddities caused issues) ...
