Does Hans Franke have a website? Any contact details?
He does not currently have a web site, but if you contact me offlist, I will be happy to send you his e-mail address which is easily found on the internet as well. My contact info is e.east.man at g.mail dot com, less the periods
Hmm, my newsgroup feed server doesn't like attachments. E-mail me and I'll send them to you.
My card has the 1M Flash Rom and the CPLD circuit, but I don't have the pins in place to attach the daughter board. The connectors Hans referred to, pc104 connectors, run along the top, bottom and left side of the logic area of the board to pass the signals 'up' to the daughter card. The ones on Han's board go on both sides of the board and give you a pin socket on one side and pin header on the other. You can get either or both, depending on what you need. My board does not have them installed. Hans assured me I would have no problem finding them 'locally'. I can't find my daughter board so there are no pics of it. But essentially the board is 3 by 2.75 inches and fits directly over the logic area of the BastelCard. It too has the maximum number of pin holes that will fit in that area. All the pins operate as a bus system and with the connectors recommended, can be stacked several boards deep.
The CPLD provides 4 programming registers and all the logic necessary to access and program the Flash chip from the Apple II.
You can access the top 64k of the card Flash Rom can be seen in 256 byte chunks at the cx00 address space. Any of the 1 meg can bee seen in 2k chunks at C800-CFFF. So lots of room for card rom revision testing.
There are jumpers that correspond to the the control register so it can be configured for a specific section of the Flash Rom when you reset or start-up the computer. The setting can be changed via software after that.
There are LEDs that monitor the logic state the card is in, etc.Hans says the flash is a 29F400 or similar series, "they all work the same". My chips number is 29F800BTC-70
The logic can be reprogrammed because it is a CPLD... My chip's numbers are iMA3-128/64 1OYC-12Y1 L103APA8 (I don't know which ones are relevant.)
As you look at the card, the jumpers (9) are on the right side at the top. Below that is the CPLD header for reprogramming the logic, and at the bottom is an extra header for your own purposes.
Likewise there is a jumper for your own use as well as one of the LEDs on the back.
It's a nifty card with lots of control signals and lots of expandable space to play on. :)
Thankx, Ed
