  1. Just spotted one difference... mine has a 50Mhz oscillator... otherwise it's identical to the OP's picture.
  2. Resurrecting this, since I recently picked up a Maxell-bombed SE/30 with this exact same card... Interestingly, the ROM on mine has a label with "Spark Monochrome". @unity did you ever get it working? Anyone know anything about Spark"
  3. I recently acquired a Total Systems Mercury 030 accelerator from another MLA'r... it had the default configuration and works perfectly in my SE - now SE/030! I'd like to try it out in my Plus, which I know it supports. However, I can't find any documentation on how to set the jumpers and connect the Mercury to my Plus logic board. I know I'll need to solder some headers onto the 68000 (my Mercury has socket headers, so I just need pins on the 68000), and I believe I have to tap into the oscillator on the Plus logic board and possibly also 5V power... Does anyone out
  4. Sure... could not tell the orientation from the backlight shot ...
  5. I think you'll find that's pin 7... assuming that chip follows TTL counter-clockwise numbering convention. I did try out MacTest the other day... but not on a 68k machine (all mine were out of action). I couldn't see anything obvious about 'remote' mode, however, but I suppose that may be a vintage 68k-only thing... I gotmy SE back up and running today, so I'll have another go with the period-correct version tomorrow or over the weekend. Something else... I was pointed by an acquaintance (who used to work for Apple years ago) to the following... - https
  6. I'm wondering if it might be down to your Mac's past life... there are actually two lengths of case screws: I've found in the less adulterated (perhaps Plus and later?) ones I've worked on that the 'shorter' ones are used for the CRT and for attaching the internal frame to the case front. YMMV...
  7. In that original doc I was referring to, lower down it stated: So my guess is any (68k?) Mac that'll run AppleCat/MacTest (and has a modem port) should work... Obviously the Color Classic wasn't out at that time... I'll see if I can at least give MacTest a spin today...
  8. I've had a few things get in the way... but hoping to have a go at bringing my Portable back to life in the coming week... I've downloaded the various MacTest options from the link above, but the document refers to a special 'combined' version... AppleCat/MacTest Portable. I'll have a trawl through the files from MacintoshGarden... but has anyone listening heard of this unicorn?
