Yep, indeed it was 5v.

I've got a Centris 610 logic board that I recently recapped. I replaced all the leaking electrolytic caps with tantalums. It is working, mostly, though seems to exhibit some instability. I do notice that I don't get much for voltage across C50. Can anyone confirm if there is a DC voltage across...

I've had two different G3 PDQ PowerBooks. Using an IDE to mSATA adapter, I could never get the internal optical drive (CDROM in my case) to be usable. I tried both the Ableconn IIDE-MSAT as well as a no-name IDE to mSATA adapter off of eBay. Tried a few different mSATA drives and none of them...

Thanks! I did get the crystal to start functioning again. Not sure exactly what I did, but it seems to be working ok now. The frequency appears to be 16.38MHZ.

Hi all, I'm troubleshooting a non-working 804av. The board was previously re-capped, but currently isn't giving a startup chime or doing much of anything when power is applied.  Not sure if it is related or not, but the ATECS chip isn't providing any clock to the PSC. Digging further, it looks...

I had a copy of BPI Accounting. It came with a Lisa computer my parents picked up second hand about 25 years ago. I remember playing around with it (it was a separate environment outside of the Office System). I ended up selling it with that Lisa back in about 1999.

I replaced the foam in a Lisa keyboard not too long ago. I did all of the keys and it was quite time consuming, but in the end they all worked fine and it was worth it. I used some 1/8" thick foam mounting squares from a craft shop and trimmed them to fit. Ideally, if you could find something...

If you think U1 (24V regulator) is bad, I could probably send you a replacement part. I bought a couple when I had to replace that part on my video board and have extras.

Yea, I've tried Copy II Mac. It seemed to indicate problems reading every sector on this disk. I've also tried FEDIT, but it can't even mount the volume. I'm beginning to think the previous owner may have "accidently" formatted the game disk. It wasn't locked. :(

So, I found a guy who had some old Mac software he wanted to get rid of. Most of it was from the mid-90's, but he had a few older titles including Sim City and Hacker II in original boxes. The Sim City disk appears to work just fine, but the copy of Hacker II seems no good. I just get the...

This upgrade appears to be professionally installed. There is a DIP socket soldered directly onto the 68000 pins on the logic board. The upgrade then plugs directly into the socket. I posted a web gallery at: http://gallery.mac.com/baakre#100008&bgcolor=black -RD

Hi, I just picked up a Mac 128K with a Mac Rescue upgrade installed. From what I understand, this upgrade adds a SCSI port, allows up to 4MB of RAM, AND supposedly provides up to a 2MB RAM disk. The original 64K ROMs have been swapped out for 128K ROMs, and the internal floppy has been...

I have used these files and confirm that they do indeed work. I used a 2732A EPROM. The tricky part is that you need to find a Z8613RS Z8. Not terribly common these days. One of my Profiles actually had one installed, so that is how I got mine. The floppy disk images are in ProDos order. I used...
