Hello C0op3r,
Is this Frankenstein Apple IIgs motherboard into Apple Platinum IIe case ? And is possible for you to named all those cards you had been installed into motherboard ?
There's a TransWarp in Slot #1, a Uthernet II in Slot #2, an Audio Card of some sort in Slot #3 and a CFFA3000 in Slot #6.
The little card in Slot #5 is probably for Stereo Audio..

<< BIG SNIP >>
Apple with their strong ecosystem may have thrived on that part of the market still, having one foot in the rich households which could afford an Apple as a gaming computer, and one foot in the more business oriented world which perhaps would play a game of chess now and then.
Apple was also strong in the Educational Market in the U.S., Canada and Australia.. Especially in the Pre-College Market..

I just came in to update this. Sorry Mark, someone already took it
No Problem...

Upgrades include 16K and composite mod. The only thing preventing me from enjoying this fully- is the lack of a joystick. Any suggestions ?
This is the Composite Mod mentioned previously?? Or a different one??
My Uncle made a Joystick that mimicked the Keyboard..

How useful was a joystick on the zx81 ? Most things just seemed to use the keyboard

With all the "new" Vintage Computer "stuff" being made, last week I got a couple of the CoCoPSG cards for the Tandy Color Computer..
These are a new card made with a single Yamaha, YM2149 chip..

The research I have done so far, indicates that FPGAs can work in Parallel, so the Programming Language reflect that..
And that Varilog is a lot like 'C', verses VHDL....

And yet in all this time an acclerator hasn't been made using the Carte Blanche. What gives?
For me it's the lack of knowing VHDL or Verilog....
I would suspect that it the Issue with most of the other adopters of the Carte Blanche II, so far..

Unfortunately, Apple II FPGA designers have a tendency to keep the design closed, especially accelerator projects.
For Run #01, one of the options was to use the supplied WDC65815, but it was limited to 1MHz. Essentially the Carte Blanche II is setup as a Alternate Processor Card, with the WDC65816, ( Instead of a Z80 or the MC6809 ).
This is the Schematic for the Carte Blanche II.
This is found on the Carte Blanche II Developer Resources page.
This is the WDC65816 Accelerator Card ( Project #41 ) in Altium Designer 10 (27009).
This is found on the Carte Blanche II Demo Project, Page - 6.
Because of the Zip Chip, the Rocket Chip and the Applied Engineering Trans Warp Cards, as well as the Modern Boards, making an Accelerator is totally feasible..

Is there an ordering page that describes all options and cables and daughtercards?
Not that I have seen...
Contact Steven directly or on UseNet.
The Daughter Cards, like the I/O Board have Gerbers available.

I don't think it can be used as an accelerator (there's a 1mhz 'proof of concept', but that's it). The card seems to have impressive capabilities, but looking at the list of projects you can turn it into an expensive sound card, ram expansion....that's about it from a practical standpoint.
While it should be possible to make an Accelerator out of the Carte Blanche II, no one has, ( yet ).. Run #01 shipped with a 14MHz 65816 chip, and if the ASIC Logic of the Zip Chip was implemented on the FPGA, it should be very possibly to make an Accelerator.
I would have thought an accellerator or video output card would have been done by now, but apparently not. I'm interested but don't see any good uses for this thing, considering how little has been done with it after all these years. maybe I'm looking int he worng place.
VGA and HDMI were available when in originally shipped in JUL-2015..
I ordered my Unit with Option #4 ( out of 4 ):
4. IIe VGA video card + Apple speaker circuit + Mockingboard + 1Mhz 65C816 replacement processor (motherboard processor disabled and replaced with CBII's 65C816).

First I have heard of this device. It looks like an accelerator for the IIGS. Am I correct? A "Vampire" of sorts? If so I am SO on board. Is the developer taking emails expressing interest of purchase?
An FPGA is Programmable Hardware... The concept of making an Apple Accelerator, should be possible, but no one has attempted that yet..
These are the Projects, ( so far ) that would benefit the typical Apple ][ user:
Project 25: ][gs VGA Video Card
Project 31: Circuit Cellar's TMS9918A Video Card.
Project 33: ALF Apple Music Card, MC1.
Project 34: Z80 SoftCard with Z80 Softcore.
Project 37: MockingBoard Audio Card.

In the last 48 Hours, Steven Howell of applelogic.org posted in comp.sys.apple2 that he is getting ready to make another run of the Carte Blanche II.
This will be for the Card Only, no Extras... He is ESTIMATING a price of US$195.00, which would not include shipping...
If you missed getting one from before, now is your chance--> Carte Blanche II

I have a couple DB25-DE9 adapters that I use.... I can MAP them out for you....

I am still working on my Networked Games....
I have a good feeling that I can get something delivered this time..

It turns out it's not a first run. Tandy restarted serial numbers.
Very Interesting....
How do you find that out??? Do you know what Rev the Motherboard is??

What was the Error in the Listing???

Your First Picture, that cable will only provide the Outside Shield... With no Center Conductor, it won't work at all...
You need a Cable with plugs more like the Second Picture...

Learning Assembly Language is the way to get Full Control of your System...
Top Porter is working on an AppleSoft Compiler that looks like it generates pretty fast code..
I am a long time Apple ][ user, ( since JAN-1982 ) and have just started getting into the Tandy Color Computer, which has the Motorola MC6809 ( or the Hitachi HD6309 ).

The Apple II Enthusiasts group has a lot of posts...
I would follow the Apple ][ Game Programing group... Tom posts there too, and much less traffic...

I find Tom Porter, Impressive, because he has not learned how to Count in Hexadecimal, ( yet ), and is tackling developing a BASIC Compiler... With incredible results.
Just Impressive....
