          I'm wrorking on a program for my COSMAC Elf Membership card to calculate
          all the primes up to about 900000. The tricky bit is fitting the results
          in 32k RAM :-P Don't think it would make much of an exhibit though.

          I've also been working on doumenting/repairing at least one of my pair of
          Olivetti Underwood 288 adding machines, but that will have to be on hold
          since I have to move next month.

                  Sorry - the drive is on its way to back to Texas soon, as it was just borrowed specifically for this project. The project itself was pretty cool - i built a little robot that bolts onto the back of the drive and moves the giant voice coil, since the servo/positioning electronics were broken, and I just tapped the analog read head directly into my own sampling electronics, as the ADC stuff was broken too (35 year-old electromechanical systems don't hold up well, it turns out).

                            Awesome! Those sure are neat little S-100 boxes. If you don't have one running by then, perhaps we can get it fixed up during festivus.

                            Personally, I've been working on mostly S-100 stuff as well. I'm working on an "ultimate memory board," which is an all-static 64K board with some neat options I'd wanted for a while. First of all, it's jumper-selectable to enable either a 62256 32K x 8 SRAM or an EPROM/EEPROM in the first half of RAM on /PRESET. It can then be toggled between the two devices by a port output. The second half of memory space is filled by another 62256, which is jumper-selectable to be enabled or disabled on /PRESET so that it plays nice with memory-mapped things that don't assert /PHANTOM. It can also be enabled/disabled through a port output.

                            That's all of the memory on the card at the moment, but I laid out the port select circuitry and data bus buffer enable circuit so that additional devices can be added. This would allow for memory banking by adding basically just more RAM sockets! The whole thing is wire wrapped and draws around 250 mA for a full 64K! Mostly this board is for my bench test setup, which runs off of a limited supply. Being able to switch things in and out in software makes it more universal for various test conditions.

                            I'm going to try and get the Ohio Scientific Challenger III set up on its own bench soon so that I can start hacking around with it. Immediate plans include dumping the ROMs and storing them and constructing a single memory board to provide 48K of base RAM plus 8K for CP/M. Currently my RAM arrangement consists of three fully populated 16K 520 boards and one that's partially populated -- that consumes half of the backplane slots in the OEM chassis!

                            Thanks,
                            Jonathan

                              I see fiche readers come through PSU surplus, once in a while. Is it
                              worthwhile picking up one?

                                  Sounds like a great game ! You should call it "Mystery Brace Burger". You
                                  have to determine whether the burger is safe to eat or not. If you are right
                                  your health goes up, if not then it goes down etc.

                                          Just to keep some Apple stuff in the mix, I've also been working on and off on a Apple II proto/hobby board design. I could use some ideas for fun projects that could be done an a vintage micro proto board.

                                              If you're actually interested, we might be able to work something out! I had access to a machine at Columbia that could digitize the frames pretty well, but it needed to be positioned manually. Each microfiche sheet has a ~15x18 grid of pages, and it took me something like 2.5 hours to digitize one sheet. The whole set is about 21 sheets. I unfortunately don't have an extra ~50 hours to sit in their library scanning things at the moment.

This is unfortunate because I have several years of early microcomputer magazines on fiche. The focus mechanism might as well be a Chinese puzzle.
