I for one would be more interested in a 6800, personally. It seems at though the pinout and various functions of the 6502 and 6800 are quite similar enough to make a 6800/6502 board that can be jumperable for either. From the looks of it, there would only be a handful of pins that would need a configurable jumper. Thus, would it be possible with a bit of redesign to make a combination board to get "the best of both worlds" and perhaps double the number of takers on this board?Just a thought...--On Sun, Feb 10, 2013 at 2:53 AM, Paul Birkel <pbi...@gmail.com> wrote:
I'd say that the 6502 CPU PCB is never going to happen given only 6 (3+2+1) requests at the moment (which I'll increase to 7 (3+2+2) :->). It's a "lost cause", which would be very sad. What could be done to make it more "interesting" to a wider audience?
If it has a intrinsically-limited audience, could we work out a higher per-board cost against a smaller run and see if we can find a trade-point that will get-it-done? I think that you earlier said that you were paying $150 for 4 boards with tin-connectors (so ~$40 per board)? If we had, say, 8 or 10 or 12 orders (half our usual threshold) what would be our options?
In effect, I suppose we could think of this as a 2-fer where boards cost $40+6 each (and a "3 board" order ends up with 6 boards at the usual 6-board price).
Just exploring options in "viable". Otherwise I'd say that the 6502 CPU PCB "is toast" :-<.

I am starting to think I should have gotten a larger order of the PCBs since they are going quickly. Some boards go fast and others go slow. I am kind of getting the hang of this but not quite yet. I know Z80 CPUs, backplanes, IDE, prototyping boards, ZFDCs, and some others go fast and I should order extras.
I am patiently waiting for this darned S-100 68K CPU board to complete PCB trace route optimization. This board would try the patience of Job. It is on the second pass and looking good. It can’t be too much more. If it goes on much longer I may just take it as it is and press with it. We’ve got good momentum going and I’d like to keep it rolling.
Regarding S-100 PCB reorders, what would you and others like to see next? I am thinking S-100 4MB SRAM boards and S-100 IDE V2’s are always popular. On the waiting list the two highest boards are the S-100 IDE V2 and S-100 buffered prototyping boards.
Please see the attached S-100 waiting list. The boards on the far right-hand side are all still in development. The S-100 6502 V2 CPU board is ready to go to order as soon as there are enough to warrant a viable PCB manufacturing order. Also the S-100 uPD7220 GDC is ready to go whenever as well. It is in a quasi-developmental state yet but probably could go straight to manufacturing since it worked so well on the ECB side. The design is pretty solid I think.
Thanks and have a nice day!

If they are not already spoken for, I would like to take 2.

Hi
There are three (3) S-100 Regular Prototyping board PCBs and eight (8) S-100 LAVA PCBs still available
aka “Basic S-100 Prototype Board” (scroll down to the second board description). These are going fast so please act soon if you would like one or more. Approximately 90% of the boards have already gone to their builders.

S-100 LAVA PCB is for a VGA monitor compatible display. Uses Mylium LAVA-10 chip module (based Spartan-3 FPGA)

The S-100 LAVA works fine and does what it was designed to do quite well. However, in my personal opinion the S-100 LAVA capability has been barely even touched since the current software uses the board as a VGA monitor compatible text terminal replacement. I believe it is capable of quite a bit more text and graphics capability with further developed software.
The S-100 LAVA is capable of 800x600 @ 16 bit display (65536 colors -- RGB565) with 32MB of SDRAM and 8 MB of Flash it should be easily capable of being an X-Window server and who knows what else. It makes a logical pairing with upcoming S-100 80386 CPU and S-100 68K CPU board PCBs currently in development.
These PCBs are $20 each plus $3 shipping in the US and $6 elsewhere.
Please send a PayPal to LYN...@YAHOO.COM and I will send your boards right away!
Thanks and have a nice day!
