Re: [N8VEM-S100:4675] Re: S-100-16M-SRAM-MEZZ-V6c Board

Why not just keep a folder on the wiki for each of the S100 boards, a lot is there already.

As you mention use a nested folder for the older versions with notes, patches etc, just like the ECB boards.

Then have a reference (link) to them from John's pages, which I agree are very interesting

and informative (love the historic info).

Delineation between board versions should be made very clear to avoid confusion regarding notes, patches, etc.

Folders should do that pretty well I guess.

On the ECB boards on the wiki site, people usually make a folder and move all the old files into it when a new revision is rolled. PropIO, SBC-188, Color VDU, all have been rolled to Rev 2 and all the Rev 1 info is there.

I really like the format of S100Computers.com and the "story" of each board, I think it explains the design well and if you read about each boards in order starting with the first one from years ago you learn a lot about the S-100 bus! And it's cool to see it progress toward the 486 (or maybe AMD 586/Pentium?) board at the "end of the rainbow". I literally went out and found my Vector MZ to play with to lean before I started building, because of reading the website.

But I do agree some change control would be good. The group has run almost every board through fabrication since January. I've collected them all - but I'm just getting started building. I'd hate to end up with "superceded" PCBs later where the info isn't there.

If there's anything I can do to help, let me know. I'd rather John be spending the time on boards, I'd be happy to help with documentation.

Thanks for the update - probably should come up with a strategy to keep a history on each board as over time we are going to have different versions of some boards with different build configurations and not everyone is going to get their boards built before it might be superseded by a new board. But if someone wants to go back and look at thing say for V1 of SMB board your site doesn't have the old schematics and board layout so you have to go to the PBworks site and hope someone created a folder for older board and archived things. I think this is going to be a problem over time that we probably need to think about.

Opp’s sorry about that Dave. I have redone the “build notes” to include both mezzanine boards. See:-

Hi John

Can you put back on your web site both versions of the mezzanine board - so that people can see the original with the patch. I am not sure I am going to move up to the new mezzanine boards (probably will) but now there is no reference to the original board and the patches required to make it work. I think when you update web site you need to leave what was originally there and then add new sections (probably with revision number and/or date for new section) - not delete and replace - the same has happened with other boards.

John -

I assume this was with the CY62167ELL-45ZXI ram?

Todd -

Let the group know when you're ready to ship out a few!

Todd just a quick note to let you know the V06c version of the mezzanine boards checked out fine on the 16MG S100 RAM board. I hammered them fairly good with the 80386 board, they did fine.

Soldering the chips on to the board is quite tricky. I found it best to aligen one corner, then orientate the chip and do the diagonally opposite corner, then run the salder tip along the pins. With a wet tip there is enough solder on the pins and the board for contact. However I had one chip where the pin did not make contact, took me a while to locate it. These boards are definatly not for anybody with shakey hands

Will next do the 32MB 80386 board, but for now I feel confident sending them out to all 16MB board users.

Thanks Andrew and Dave for all your help on these.

John
