  1. You should be able to use it without the rom card, just don't use the modified system rom. You can always email @bbraun.
  2. This may be of some help: http://www.synack.net/~bbraun/classic2.html
  3. You will use the 1996 disk, here is the read me I extracted: ¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥ READ ME ¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥¥ The February 1996 Macintosh Family Diagnostics Update Mailing includes separate CD's, diskettes, and User's Guides for MacTestª Pro for 680x0-based Macintosh computers, and for MacTest Pro for Power Macintosh. The information in this READ ME file refers to MacTest Pro for 680x0-based Macintosh computers, and is effective as of 02/21/96. This file contains important information about the MacTest Pro application, its test modules, and the MTP Eme
  4. Two cases I can think of where techstep has helped me: 1. Had a macii board that would intermittently sad Mac with no video, the techstep revealed it was failing cpu tests so I solved the problem by reseating the cpu. 2. Had a se/30 sad Mac but could not see the error code, I did a ram test and the techstep indicated that the board could not see SIMM 1, I found a single open trace that looked good under magnifying glass.
  5. I don't know that there is a rule against it. It's just my policy.
  6. I stumbled across this: 26259951.pdf There is mention of a Maccat test. I wonder if it would shed light on anything by running tests similar to a techstep. I have a techstep (which obviously is not compatible with Portables) that has helped me fix a couple of other boards simply by elaborating on a sad mac error code.
  7. That's probably a fuseable resistor, did you check it with your meter?
  8. Whats the resistance? Should be near 0.
  9. Near the battery power connector.
  10. An expensive mistake, Did you check the fuse? Then, you’ll need to check the mosfets: https://www.utm.edu/staff/leeb/mostest.htm
  11. After researching a little more I wonder If the problem might be in this area?
  12. Like this, all of the pins are shared except CS (Chip Select). Front and back for sure and maybe even left to right For more info: https://ece-research.unm.edu/jimp/310/slides/8086_memory2.html
