Hi All,

Im looking for expressions of interest on this S100 system. There are many boards as pictured (links below). The main system is an 18 slot backplane with a Z80 master (own design) and x86 slave, this is a 80386 board (a reworked design of John at s100computers) and/or a 8086 board (Johns design). There are multiple other boards, my own 8MB SRAM board for the S100 bus (two of 0-8MB 9-16MB), I think only populated with 2MB currently. An FPGA i/o board (my design), the 80386 32MB RAM board (John design) still needs finishing with OTT ribbon), Compact flash board. There is a Serial i/o board with a Flash 25P storage chip on it, this is my own design and makes development of code really quick.. no more writing proms.

As it stands the system bootstraps itself from the Z80 "loader" prom that gets the system into a Z80 monitor via reading it off a flash device, the user can then select to switch over to the x86 slave. When the slave is up, there is another monitor (written in x86 source) and one can move the system into protected mode. There are general i/o and debugging routines in each monitor. Im happy to provide the source and whatever resources I have. I'm also happy to provide PCB files and there is a stack of bare PCB's enough to make close to another system x2 or 3. The current backplane is not terminated as I only use CMOS buffers. i think i have a terminated 18 slot backplane, if i find it ill throw it in.

Happy to give any more detail, just ask






















 
Love the idea but what is the cost? I have been looking at obtaining an s100 backplane, and populating it with a 6502 and 80386 so this is kinda up my alley. All depends what the price is.
 
Hi,

Looks like all reproduction boards ... sadly, I could only afford the shipping to the US for anything. It would be neat to get a multi-color Altair kit though.

I think I have enough knowledge and skill that I could assemble it all into an Altair cabinet and make it work. I kind'a think it would deserve a clear top to show off the colorful system.

Hi twolazy. I wouldnt imagine the price of shipping would be a lot, the boards themselves along with the backplane are fairly light. There is no heavy PSU or anything. With respect to price, im willing to take offers. Feel free to PM me. I also have a space unpopulated S100 backplane from a PCB run from a few years ago.

Hi @wperko, yes these are all reproduction and/or custom boards. They have all be designed to be S100 compliant. I imagine shipping to the US would not be so expensive (as said above) as there isnt any heavy items, only the boards and backplane. For the altair cabnet, you might want to check the length, the 18 slot backplane is quite large. But in saying that, the boards can be plugged into any S100 backplane, and there are many re-productions that fit the Altair. A clear top would be awesome!

Hi,

IF you can accept sending me the kit for the cost of shipping, I'd love to buy it. I'm retired on a very meager pension, so that's why I can't offer more, but I have a full size, empty Altair 8800 case/cabinet that I'm sure it would fit into, and if the back plane is too large, I can get a smaller 9-slot reproduction back plane.

I am sure I can get a friend to cut me an acrylic top for the computer ... it's just two sides and a top that screw on from the sides.

Sorry @wperko, these boards have 1000's of hours and 1000's of dollars sunk into them in design, production and testing. I can't let them go for nothing.
