So, I've been going though the TIL articles and saw that the HD20 Driver File + System File Revision 3.0 or greater + Finder File Revision 5.0 or greater allows the 128k and 512k to read 800k disks? https://savagetaylor.com/TIL/TA33199.html, has anyone tried this? I thought the HD20 driver...

The CF2IDE with an industrial card worked for me in my 630 DOS system https://www.savagetaylor.com/2023/12/17/ide-replacing-your-old-ide-drive/

Odd, I thought I had made a .dsk.bin to maintain the resource fork. Will re-do and reupload. Do you have one of the New Life accelerators?

Odd, I made the image using diskcopy 4.2, I will do a check when I get home.

https://www.savagetaylor.com/2018/01/01/mac-os-standard-format-specifications-apple-kb-article-8647/ For HFS The maximum volume size under System 6 and System 7 is 2 GB (reduced by 2k to 2,097,150KB using Apple’s HD SC Setup 7.3.5). System 7.5 increased that limit to 4 GB (reduced down to...

From what I’ve read on Low End Mac and MacWorld (April 1996 page 47), the connection speed limits for serial connections are likely: 19.2 kbit/s (2.4KB/s) on 68000 Macintosh Systems 57.6 kbit/s (7.2KB/s) on all other pre-PPC Macs except IIfx and Centris/Quadra AV that have IOP ports 900 kbit/s...

It might be on one of Apple's CDs or DVDs https://www.savagetaylor.com/2024/01/31/apples-developer-cd-series/#1999_and_2000_the_mac_os_anthologies

Hi @ironborn65, I've been looking in to what happens when you are dealing with both internal and external devices in a SCSI chain, and I've updated my page to add more information for the main situations I could think of: No internal SCSI devices and only one external SCSI device, No internal...

I wanted to put together a short guide for how to use SCSI devices on my site as part of my page on comparing modern storage options. Based on what I read in the 1990 Macintosh Reference Guide, and the Macintosh Plus Owner's Guide. It looks like the Macintosh Plus requires a pass through...

I did a bit of a reword on my list to include Floppy Drive and HD20 replacements and a short summary of what SCSI is and key points that someone know to using old Macintosh Systems would need to know. Feel free to comment here or on the page if any of the information I have is incorrect, or if...

Previously I had weird behaviour with CF2IDE adapters, but those problems stopped when I started using industrial CF cards that are intended to be used as a replacement for fixed storage vs. removable storage. https://www.savagetaylor.com/2023/12/17/ide-replacing-your-old-ide-drive/

I believe that for some systems, if you performed a soft reboot the contents of the ram disk will stay in memory. The Macintosh Portables and Powerbooks can do that. TIL08090 System 7 Installing on a Macintosh Portable's RAM Disk, TIL12259 Powerbook Settung up to run from a RAM Disk, TIL17699...

Do you mean that you want to use an emulator to edit the contents of the .hda file? If the hda file only has a single volume you can use Basilisk II to mount and edit the hda. I have a guide on my site. For your comment about the hda file being locked. Make sure it hasn't been set to...

What about the OS anthology DVDs

Seems to line up with the values for the IIvx https://bluescsi.com/docs/Performance 1.57MB/sec read and 1.4MB/sec (1367 kbytes/sec) write.

Definitely this. I always do a full format (no quick) of my SD cards before I put image files on the so that my image files aren't fragmented

What is the transfer speed of the SD card? I have found that some of the old 4GB or less cards are a lot slower than I expected
