When I tried using the .dc42 profile image that I had working with LisaEm 1.2.6 with the new beta version, I got the ipc error again. Furthermore, when I attempted to create a new profile image by installing LOS 3.1 by booting from the first install floppy image, I get "The Tag checksum failed...

I tried to use the beta version of LisaEm you provided, but whenever I attempt to turn on the virtual Lisa 2, I keep getting the error, "cpu68k_makeipclist: But! ipc is null! Stopped at cpu68k.c:cpu68k_makeipclist:1071 with code :501". When trying to use the blu-to-dc42.exe program with my raw...

I was able to convert my disk image to a .dc42 file using the provided tools. Unfortunately, I was unable to get it to work with LisaEm. Upon turning on the virtual Lisa 2 in LisaEm, it turns off immediately. Upon trying again, the light stays off, but the virtual Lisa 2 screen turns on with a...

My main computer runs Windows 10, but I have a MacBook Pro. If you, in fact, have a binary of the blu-to-dc42 conversion program, I would definitely be interested in trying to run it on the one computer of mine that actually does run macOS.

I am interested in trying to use that "blu-to-dc42.c" program, but I haven't had much experience in compiling other peoples' programs, and CodeBlocks keeps throwing out compiling errors. I have attempted to fix many of them, but I just can't get the program to run. Do you know how I could get...

I attempted to edit the raw image with HxD again, this time only selecting to "Lisa HD Img BLUV0.90", which would indeed end at byte $0213, and now, while IDLE still won't boot the system, I get a different error. The error I now receive is error "75", which, according to the Lisa FAQ, indicates...

I removed all of the data up to offset 000010A0 in HxD, which should be the first 532 bytes, since each offset contains 16 hex numbers, and therefore, 16 bits, or 2 bytes. Each offset is in multiples of 10 in HxD. The last portion to be deleted also includes the text string, "NÐERROR"...

I recently figured out how to use BLU (Basic Lisa Utility) to transfer an image of the entire Widget hard disk on my Lisa 2/10 over a null-modem serial cable to my MacBook Pro as what appears to be a raw binary file. The file size is about 10 MB, which seems appropriate, and by looking at it...

This one has the correct model number: http://www.ebay.com/itm/Iomega-ZIP-100-Portable-SCSI-Z100S2-Drive-/252442545710?hash=item3ac6bf8e2e:g:OBIAAOSwhOVXcyah What kind of Zip disks should I get? Would any type work?

Would this one be appropriate? http://www.ebay.com/itm/Iomega-ZIP-100-SCSI-Z100S2-drive-EXCELLENT-CONDITION-/112041345066

I would like to back up my Macintosh Plus's external hard disk, which all of my stuff is on, including the system folder. I've heard that a SCSI Zip Drive may be good for that. If so, what kind of SCSI Zip Drive would I use, and how would I install it? Does any SCSI Zip Drive work, or must it be...

It is possible that it is the sound of the flyback transformer, and typically signifies the near-end of its life. If that is the problem, then your flyback doesn't have much more time, and should be replaced, before it burns out, taking other parts with it, as it did to by Mac Plus. On the other...

I once had a problem where the computer would freeze randomly, and garbage would appear on the screen. Often, I would even get jail bars on the screen on startup, with no chime. I fixed the problem by removing the ROM Chips from their sockets, and brushing both sides of the pins with sandpaper...

A similar problem happened to me a while back. If you don't replace the flyback transformer as soon as possible, there is a high probability that it will fail. That whine means that it is just about to fail. If it fails, it will take some other parts along with it, so if you don't want to...

I already tried pressing on the keys and wiggling them, which didn't work. I am pretty good with a soldering iron, as I have desoldered about seven key switches, and then removed them. I deconstructed them, so that I could clean the contacts with contact-cleaner. Despite this, the problem has...

My Macintosh Plus is hooked up to an original Macintosh Keyboard M0110, and many of the keys are intermittent/unresponsive. Playing Prince of Persia became almost impossible, as did typing. I tried using WD-40, and then, when that didn't work, I tried desoldering the switches and cleaning the...

If power outages don't cause data problems, then what causes a head-crash? Also, are you saying that I shouldn't plug the system saver into a power strip? The surge protection on the system saver probably doesn't work, but it still counts as a power strip, since it also supplies power to the...

I'm going to assume that a System Saver counts as a power strip, since it has two power outlets on it, one of which has a Hard Disk hooked up. A UPS is usually a power strip, so does that mean that hooking up the System Saver to the UPS is dangerous? If so, is there any safe way to protect the...

After a recent power outage, I decided it would be a good idea to buy a UPS (Uninterruptible Power Supply) to protect my Mac plus and its hard disk which are both attached to a Kensington System Saver Fan. I want to make sure that the Hard Drive will not suffer a head-crash from a power-outage...

I replaced CR20 as described and pictured, and the computer is still working fine. Anyway, what makes CR20 a high-failure part? What is its purpose?
