Actually that is one Andrew (and perhaps somebody else) did way back. It is shown her for completeness.

John: Yes, I have a couple of those, thanks. The objective in this thread was to reproduce the earlier-design unbuffered "regular" prototype board for various-and-sundry purposes. I've lost track of where it's published on your site (help!); maybe you've taken it down by now. I've attached a photo to jog memories :->. Hopefully it will transmit successfully.
I agree with your points, and perhaps someone (else) wants to put together an order for the (wonderful) Buffered Prototyping Board?

Paul understand your desire to get as much real estate as possible, but having played around with a few prototype board layouts, you may want to consider inserting a row of chips for buffering the address, data, status and control lines and connecting them to the bus. If you are going to actually use the bus, no matter what you do you will need these connections. It’s very unrewarding putting together a new board where initially you spend your time hooking these things up and in reality they always seem to take up more space if wired in by hand.
Second I would run a ground line along the edge on the front side and a +5 on the back, again for the same reason.

Very aggressive! I'm concerned that the top-row is too close to the edge (drop?) and that the (bottom) row of ICs/caps wouldn't actually fit side-to-side in the allocated space. There have been problems in the past with the library nominal-footprints not accurately reflecting part sizes and clearances. Is the +5 trace heavy enough? Ditto for ground (at least the last-mile to the fingers)?

I haven't been keeping close count, but it's now looking like a "standard' run of 30'ish boards would fit your guidelines. We seem to be closing in on 20 commitments, aside from whatever your desires may be.
Thanks for the "OMO" explanation! I'm not a gamer, although I do agree with the rest of the OMO credo :->.

Trained? Yes, I can now roll over and I do a pretty good "fetch" too.
Life time buy is good, the thing with these boards and why I'm not worried to build a lot of them, is they can be used for any project. You can ignore the S-100 bus, mount a regulator and go. I'm planning on adding two more holes on the bottom 2 corners, so regular standoffs can be used to mount the board.
OMO? That is for my old "Clan" name from my days of playing Homeworld. Stands for "Old Men Online". The clan is still around, I don't participate much anymore, but they are mature gamers that have earned a good reputation in the gaming community. But watch out for "CrankyOMO", he can be a little impatient at times. Google Old Men Online, you'll find their web page.

All "trained" Josh ::->?
Anyway ... I've decided to stock up along with Steven. Please list me for 7 boards, which for me ought to definitely be a lifetime-supply .... grabbing for the gusto (well) in advance!Thanks. May one inquire (and get a reply :->) as to the acronym expansion for "OMO"?

Thanks Matt.
I'm going to verify pricing first, once I know the exact the cost, I'll announce it to the group.
I expect shipping to be more, but I hope to get a cheaper price for the board. Then we need to guess the exchange rate.
Cheers,
Josh

Please put me down for two (2) boards. I'll keep them just in case. Let me know who to wire the Paypal to.

Subject: [N8VEM-S100:2388] Re: Board Run: Unbuffered PrototypingHi,
I live in northern Virginia. I am interesting to purchase 6 unbuffered prototyping board for this coming March due to my restricted budget. I am not surprise about many people may not interesting to buy the prototyping boards because of tremendous expensive to buy wirewarp equipment nowadays.
Secondly, I am still thinking about drilling/milling machine (see eBay and search for 3020 desktop router engraver drilling/milling engraving machine cnc. Also, see http://www.youtube.com/watch?v=na9-USi_hZQ NOTE: should have large clear plexiglass enclosure to avoid fiberglass dust into lungs. The only disadvantage about this method that have lack of vias (between layers. It may need to solder both sides as much as like old days with Tarbell Cassette Interface board.
This will be great for prototyping work???

I have brought this topic up several times over the past year or so (most recently 2-3 weeks ago, without response) but there's been insufficient interest (borderline none) and I haven't had sufficient immediate need to strike out on my own with a run of only a few much-more-expensive boards. I'd like to see us get the volume up to the point that we approach/reach the $20 per-board cost, but that means at least 20 boards. I'm not sure that each of us wants 7 boards ... but three interested parties is certainly better than just one :->.
I'm located in Maryland; not sure where Steven is located. I gather that CA-US shipping cost is asymmetric -- here-to-there is cheaper than there-to-here?
I'd be willing to serve as "trail boss" if there's sufficient interest. Andrew did offer to get me started last week, but I still await sufficient interest ...
Can I get commitments on board counts from interested folks, please?
Thanks,
paul

Hi Group,
I am thinking of helping out and doing a board run. I was planning on doing the unbuffered prototype board, but Andrew thought someone else here may already have that in motion? First, let me start by saying I'm in Canada, so it may be a little more costly to ship to the US, but internationally it might not make any difference.
Can we hear a vote of which boards to build, and a show of hands who might want to build them?
I don't want to organize the group... but with a little communication I believe we can organize ourselves.
Regards,
Josh
