So to add a bit of detail to what's happening here, the VSROM stands for Video State ROM, it's a state machine in a ROM that contains the horizontal, and vertical timing info used by the video display circuitry. The A-H ROMs use the normal Lisa rectangular pixels, and the VSROM for these...

see: https://lisafaq.sunder.net/single.html#lisafaq-hw-vid_wavy Since you've recapped it already, likely it's RFI from something nearby, but first, try cleaning the PS card edge connector with an eraser, or better yet, use electronics contact spray cleaner or a contact cleaning pen. I'd make...

It sounds like the spindle motor is moving, so that's good, so the two most common failure modes (spindle motor freezing due to lack of use/hardening lubricant) and head actuator brake are not there. It could be an issue with the half moon board on the bottom of the drive, or the top controller...

Nothing happened in what way? didn't turn on? or something else?

The bad news about the corrosion is that it doesn't stop. You should clean the I/O board with deionized water, electronics cleaner and maybe a bit of white distilled vinegar. but it's likely that the corrosion goes inside the traces and keeps eating away very slowly year after year. Reflowing...

This smells like a Lisa 2/5 battery leak issue - check/clean and corrosion and resolder/reflow the I/O board. I've had this myself, in my case, I had a spare I/O board. It's not necessarily the COP421 itself, though some of the pins might be corroded, or the traces around it might be corroded...

If anyone's interested I released the beta code that includes the BLU changes. I'll need more BLU images to compare to. While lisafsh is now able to get a directory, it's not right somehow. So the metadata for the directories is right, but when I try to extract the files they don't match known...

meh, it throws error 75, and repair doesn't fix it. will keep trying.

Hi, some better news, I tweaked the tool a bit more and now both tags and data is a lot better, I'm able to run the "dir" command in Lisafsh tool and it's also able to recognize the MDDF, likely this is now working, though I don't have time today to test this in LisaEm due to work obligations...

Also tried to boot off a good profile image and attach the converted image on a dual port parallel slot (you can do that by changing the preferences, telling LOS there's a 2 port card in one of the slots, and that, say, the upper port is a profile) but the disk isn't recognized. So likely...

Good news, I found some bugs in the code, it's now producing an image where the tags are correct, however, bad news, attempting to boot from it throws a 10726 error. I found a couple of bugs in the converter program, and now, looking with lisafsh-tool, I see that the blocks that have the boot...

Ah ok, thank you for that LOS image. I've downloaded both and will check them. btw, compressing the BLU image with xz reduces it down to 3.5MB: -rw-r--r-- 1 ray ray 9.9M Mar 8 21:21 '3_-_BUILT-IN_PARALLEL_PORT_(10_MB_Widget_Hard_Disk).dc42' -rw-r--r-- 1 ray ray 3.5M Mar 9 19:02...

Meh, that ipc list error means there's something wrong with the code on that disk - so likely the conversion isn't working at all. It's indicative of run away code, i.e. a very long string of code (or all zeros) without branches or JMPs since that piece of code works on basic blocks. This...

Give this is a try, I just compiled it from the current code, but haven't (much) tested it, restore the contents to c:\program files\sunder.net\lisaem Inside the bin directory should be the tools you're after. https://lisaem.sunder.net/downloads/lisaem-1.2.7-beta-2020.03.03-win10-x86-64.zip...

So, if you go here: https://github.com/rayarachelian/lisaem and do a git clone, you'll have nearly the latest and greatest source code, and inside that, there's a scripts directory, in which you'll find a pair of Windows batch files. I use these to install cygwin with all the required packages...

Not sure about this model, but with SCSI generally you want motherboard->internal-drives->terminator, then the last device at the end of the external chain gets a terminator. You need to make sure there's no conflicts in IDs as well. You'll want something like SCSI probe to help you...

Before you take out the DVD drive, you could always burn a copy of the OS on a DVD-R or a 10.4 boot CD-R and try to boot off of that. CD-R/DVD-R media is quite cheap. :beige: Sounds like you're gonna have a quite a time cleaning this little beastie out. But look at it this way, you saved...

Nice machine, plus it's got PCI slots, and that's useful. Closest thing I've got is a 7100/60. :lol:

OS X supposedly still supports SCSI. Long as you get a card that it has drivers for, it should be fine. I've seen a few cards at http://eshop.macsales.com/Search/Search.cfm?Ntt=SCSI%20controller&Ntk=Primary&N=0&Ns=P_Popularity|1 though those are very expensive, they will work...

Do we have a way to take a 68K Mac's SCSI hard drive and turn it into a virtual disk for use with either Basilisk II or Mini vMac? (I know of the copyrom program for ROMs and obviously, Disk Copy can be used to make floppy images.) I've got a nice setup on a Mac hard drive I'd like to be able...
