candle Posted January 29, 2012 Share Posted January 29, 2012 i hope so, i did that mistake before, and it resulted in cable with every other wire twisted if this will be like so in prototypes, i can simply solder 50pin IDC connector on the bottom side and this will solve the issue what i'm worried is daisychaining of memory slots and operation of special cards like 80 column display adapters with chain broken (slots 1&2 disabled) Quote Link to comment Share on other sites More sharing options...
+Stephen Posted January 29, 2012 Share Posted January 29, 2012 Finally a reason to unbox my 800s and get them cleaned up. Quote Link to comment Share on other sites More sharing options...

flashjazzcat Posted January 29, 2012 Share Posted January 29, 2012 Superb work Sebastian. An essential purchase for all 800 owners, I think. Sadly I'm not one... Quote Link to comment Share on other sites More sharing options...
candle Posted January 31, 2012 Share Posted January 31, 2012 erm, should we proceed with this, or noone wants it anymore? Quote Link to comment Share on other sites More sharing options...
+Stephen Posted February 1, 2012 Share Posted February 1, 2012 I want it - I'm ready to prepay and help test Quote Link to comment Share on other sites More sharing options...
AtariGeezer Posted February 1, 2012 Share Posted February 1, 2012 I still want it too, just don't have the programming cable... Jay Quote Link to comment Share on other sites More sharing options...
fibrewire Posted February 1, 2012 Share Posted February 1, 2012 I do of course Let me know how it's going with that Axlon 128K board. Quote Link to comment Share on other sites More sharing options...
venom4728a Posted February 1, 2012 Share Posted February 1, 2012 I want it also, when do we need to pay? Looks awesome! Robert Miller Quote Link to comment Share on other sites More sharing options...
JamesD Posted February 1, 2012 Share Posted February 1, 2012 If I had an 800 I'd want it. Sadly every time I bid on one the price goes nuts. Quote Link to comment Share on other sites More sharing options...
JamesD Posted February 1, 2012 Share Posted February 1, 2012 ok, its done: and schematics: schematics for incognito board Ok, what is the large connector at the top for? Quote Link to comment Share on other sites More sharing options...
visionik Posted February 1, 2012 Share Posted February 1, 2012 I'm in, and I'll get whatever the programming interface is, too. Quote Link to comment Share on other sites More sharing options...
candle Posted February 1, 2012 Share Posted February 1, 2012 (edited) JamesD: its an PBI interface connector fiberwire: it works like this: you put your 128k axlon board back in the drawer, and use 1mb axlon compatible memory expansion which is already built in Ok, i'll PM you with details, and if we move forward, i'll post updates in this thread Edited February 1, 2012 by candle Quote Link to comment Share on other sites More sharing options...
AtariGeezer Posted February 1, 2012 Share Posted February 1, 2012 Q: On the xilinx download page, is just the SDK needed to do the programming? And does anyone know if it will run on Win95?, it's the only one I have with an LPT port... Thanks, Jay Quote Link to comment Share on other sites More sharing options...
candle Posted February 1, 2012 Share Posted February 1, 2012 sometimes its possible to d/l only impact software - this is whats their programmer is called otherwise whole ISE needs to be downloaded - it's over 4gb of download, and chances it runs under w95 are nil Quote Link to comment Share on other sites More sharing options...

Faicuai Posted February 1, 2012 Share Posted February 1, 2012 erm, should we proceed with this, or noone wants it anymore? ...I am IN, for sure (if you refer to making this board happen). My cash is also on it. This would make justice to the wonderful (and invincible) JM-800. F. Quote Link to comment Share on other sites More sharing options...
Ransom Posted February 1, 2012 Share Posted February 1, 2012 How much will this cost? I'm interested, but don't recall seeing a price. Quote Link to comment Share on other sites More sharing options...

Or does this plug in a memory card slot? I'm sure someone will find a use for it, I'm just not sure what you could plug into it under the shielding. I so need an 800 now.

JamesD Posted February 1, 2012 Share Posted February 1, 2012 How much will this cost? I'm interested, but don't recall seeing a price. I think price is going to depend on number of orders. But I think the number of orders is also depending on price a bit so it's a vicious circle. Oh hell... candle, sign me up for 1 if it's not ridiculously expensive; I'll try to buy an 800. I can't test anything for you until I can find an 800 but I can help lower the costs. I'll probably need a new JTAG programmer if you do any PLD upgrades because my old programmer required a parallel interface; I'm not sure I have a computer with a parallel port anymore. Let me know where to send $ and how much. Hell... I'll probably receive this and buy an 800 before I ever get the SIDE cart I ordered.

Ransom Posted February 1, 2012 Share Posted February 1, 2012 I probably can't buy testing equipment or a JTAG programmer. But I suppose such will be needed once it's finished, in the case of upgrades/bugfixes? I guess that leaves me out. Quote Link to comment Share on other sites More sharing options...
Ransom Posted February 1, 2012 Share Posted February 1, 2012 I just went back and re-read the whole thread. If I understand it correctly, the finished board will just require a half dozen or so wire connections for installation. Will the boards be delivered fully populated? (I'm not good enough at soldering to handle surface mount components, but I do fine with 80s-era stuff.) Will I need a JTAG programmer or some other equipment for upgrades/bugfixes?
