The BMOW ROM-inator II gives users the option of pressing a keyboard key to choose either ROM Disk or RAM Disk (where the content of the ROM is loaded into RAM for the purpose of changing data, which cannot be done on the basic ROM Disk)... But I believe Kay's ROM is ROM Disk only. There...

The only thing close to what you are asking is DiskDoubler, but I don't think that will work on this time 1.5MB image. You can test it with Mini vMac though and see.

As mentioned in my previous post, you must create a 1.5MB disk image with *.img filename extension. You can leave your 1.5MB image to be blank, or you can put only apps on it, or you can put a System folder on it (only one SE/30-compatible System folder will fit into 1.5MB). It's entirely up...

@OneGeekArmy & @Kay K.M.Mods Thank you for explaining. I understand now. I was simply confused by the earlier video which showed 3 images (System 6, System 7 & Blank) all being used with Crucible... It is pretty obviously that all 3 disk images show above wouldn't fit into a single 1.5MB...

@OneGeekArmy I am not 100% clear on the complete procedure. Could you please confirm if the following are the exact, correct steps for people to follow in conjunction with the Crucible software? Create a boot disk *.img file that is no bigger than 1.5MB, and put it into a folder on the...

Correct. The speed of your donor SIMM’s RAM chips determine the speed of your DIY SIMMs. 60 ns is fast enough for any Mac that is compatible with 30 pin SIMMs.

I take it you did not issue specific instructions to the seller regarding packing. I failed to do that long ago but soon learned that "people are stupid." I sometimes feel I am a complete idiot until I realize there are a huge number of people out there a lot dumber than I am, not because they...

I decided to join in on the fun... I think the rest of you folks should too!

Even if the IIfx had a fast SCSI card installed, I would guess the Mystic would be faster overall due to the faster CPU.

I look forward to your test result. And who knows... You just might be the first person to use a "Jackhammer" on a BlueSCSI! 😄

My first home computer was the MacIntosh 128K in 1984. Through all these years, I have never owned a single Windows PC for home use. So even though I probably can buy a PC for my home use for only $100, it would cost me a lot more than that in my time to set it up directly. It’s probably easier...

Maybe it's good to stay with the TLS866+, not only for the MacOS software, but also because it can program your ROM chips and just about anything else too, including the ROMs for a Mac SE and other programming projects like that? SOURCE: https://groups.google.com/g/sebhc/c/Hn0xDdiyryc

If you buy the 12pc programmer kit using Kay's AliExpress link, it includes the PLCC32 adapter (no need to buy that one adapter separately in that case)... But what's the link to the MacOS software to control the programmer?

Not sure where Kay sourced the ROM socket he installed in my SE/30 motherboard, but I purchased the RAM sockets from RS Components Japan and had them directly shipped to Kay. In the first batch, which was foolishly shipped in a mere bubble-wrap envelope, 4 of the sockets were chipped, but we...

NEW sockets are CREAM colored... My old socket was black, and it also had metal tabs. Even so, only the new cream colored socket works with the ROM-inator II... Lastly, please read the following excellent post by @Kay K.M.Mods regarding motherboard warping...

I do NOT advise the solder across the ROM SIMM pad suggestion at all because I tried it and had trouble. Why? Because solder flakes apart over time, and the flakes short out adjacent pins! No damage occurred on mine, thankfully, but it was pretty scary discovering that. As to why my Kay Koba...

I paid Kay Koba to replace all the RAM and ROM sockets in one of my motherboards. All have metal clips. I can now use a ROM-inator II SIMM without issue, whereas before I could not. Part of the issue is most SE/30 motherboards are slightly warped, bulging ever-so-slightly downward due to...

The original MP-F-51W bitmapped schematic can be downloaded here. All related schematics are downloadable here. Eugene Gillott from Canada created the vector version and gave me (JDW) permission to make it available to the public. Eugene said that he found some minor differences between the...

I'm really hard to offend so you almost never need to worry about that. I was just saying that if we think deeply on this subject, we should ponder what our Macs are capable of. I myself am a 68K Mac fan. The only PPC machine I have, aside from a couple Wallstreet notebooks, is my pair of G4...

Well, if we want to get that detailed, we also need to consider which 68K Macs might be able to achieve 10MB/s with an optional SCSI NuBUS card installed. Any thoughts on that?
