I got it for around $75 - the others that I found at the time (last October/November), were around 120+shipping.

From his picture at the beginning of the thread, this is the HMMU - sort of a low-budget alternative to the PMMU that they put in all theMac IIs without a PMMU. Here is a thread explaining... https://68kmla.org/bb/index.php?threads/how-do-i-know-if-my-macintosh-ii-has-a-pmmu-or-hmmu.38060/...

This worked for me when I had a similar problem on an old Compaq PC - its good to be reminded of the options for troubleshooting!

I see re-capping in your future, starting with the power supply (likely the cause of the your 'no sign's of life' issue) and because all the LC model's caps are leaking now, even if there are no overt signs. Obviously you will want to check the voltages on the PSU, before you begin to either...

just ...wow!

I'll bet the lead-free solder works well for this, let us know how this turns out.

Check, Check and Check (including working Mac IIs)... I may need you to talk me through the operation and its not what I planned for the weekend, but I would like to help. Feel free to pm.

There are CSII cards with the Digital 21040 chip as well. I've got one, but no longer have anything to install it in. It appears that these work in the 6500 - https://discuss.haiku-os.org/t/power-mac-6500-audio-in-beos/12481 (the problem there is no sound in BeOS, but the CSII card's ethernet...

I've previously shipped a couple of items to Canada, and if you get the right person at the Fedex store (or wherever) its only a few minutes longer to send it off, than to somewhere in the US. I recall that a correct description of the item was key.

Ouch! That was my opinion when I happened to be collecting some other items from a fellow 68lmla-er a few years back, but he had a minitower that he was offering for a good price and it has been a terrific machine. Its not overly large, and works as a great bridge machine, replacing the 7600 I...

Since your initial ask was to place a fair price, and you've done a great job communicating what you have over a couple of posts, let me sum up (and please correct me if I misstate) You seem to have all the original items (case w/ all four case feet, shoulder strap) the original extras and...

I guess three years counts as a necro-response, so here goes... the short version is androda was right - totally NMI related. First, I had to re-recap the board, which included serious cleaning. During the cleanup, I dislodged a transistor with serious corrosion and had to clean/re-tin the...
