@jasa1063 Based on the previous reply below, I think we just need to wait until the end of February, because... well... @Zane Kaminski did say "sooner than [March 2023]" after all! :-) I should also mention that being able to have acceleration without distorted sound is important for the...

Very interesting! Thanks. When you post the next test results with your new card, please let us know the brand, capacity and model of your two SD cards. Also, when you first told me about the overclocking capability of BlueSCSI v1, I was pleasantly surprised; and as you know, I confirmed the...

SCSI Probe

@eric It all sounds quite spectacular. Two questions: 1. I am familiar with config files on my MacSD units, but when I use v1 BlueSCSI hardware, the only files are my drive images and the auto-generated log file. As such, is the "config file" mentioned in your opening post something unique...

A more comprehensive chart showing vintage Mac SCSI data transfer rates is given below, and it has cute bitmapped icons of the Macs too! https://mirrors.apple2.org.za/ftp.apple.asimov.net/documentation/macintosh/Mac%20History%20-%20Models%2084%2095.pdf The LC575 motherboard in my Color Classic...

Pretty amazing stuff, Eric. Congratulations on the release. While it certainly will benefit PPC Macs the most, I can't wait to test this on a 50MHz CC Mystic! The hot swappable SD card is truly ground-breaking. Being able to eject the SD, pop it into a modern Mac to delete or add software...

@Tony359 released his video below, and I just finished watching it... It seems Tony used the Sept. 2022 version firmware presented in this 68kMLA post to program a PIC16F88 DIP, which is a drop-in replacement for the stock IC on the Mac SE motherboard. That is a wonderful solution because it...

I'm pleased to report there is now a fix for audio glitching when using a Carrera040 accelerator card (original or clone) in an SE/30, thanks to a revised Control Panel from @Bolle and GeekDot. I have uploaded it to the Macintosh Garden here...

And they come shining through! All of them look great, Kay!

Kay, Do you have the T48? I don't have either programmer yet because I almost never program anything other than Microchip PIC MCUs, and I have a ProMate 3 for that. Sadly, the ProMate3 programmer won't program the SST39SF040 chips. On Amazon USA, the price of the T48 is $73.99 with various...

Thank you for explaining. I was confused because I haven't looked at a recent revision Bolle SE/30 motherboard. I only remembered the first edition which did not have PLCC sockets. Here's the newest edition Bolle SE/30 motherboard showing (in green) where those PLCC sockets go... Photo...

@Kay K.M.Mods Just to clarify for myself (yes, I am confused) and for everyone else reading this thread, too your new SE/30 ROM works fine in the stock Apple SE/30 motherboard. I believe that to be a fact. But is there an issue when your ROM is used on a Bolle motherboard? In other words, if...

I take that strikethru text to mean you are finding the IIfx to boot faster? If so, what is your CC Mystic's overclock speed? And are the hard drives the same in both? Congratulations in a wonderful restoration!

That incredibly detailed post about archiving by @Mac84 should become a sticky or a resource. Great info! Now, in earlier comments I see that it was said that breaking a seal is good to prevent rot, but in my experience, plastic seals increase the life of any given thing. For example, I have...

Thank you very much for the two links! I've not had time yet to read through the MLA thread, but I did read through the first URL you gave me, and the specific part you are referring to is this... Unfortunately, he links to this Low End Mac page, which is otherwise superb info except for the...

Yes, that parallels the finding I put forth in my opening post. However, as I asked you in my previous post, does that information come from your own personal experience, or did you read about it somewhere? If you did read about it somewhere, could you please provide a link to that information...

No, I absolutely do NOT realize that, as per my previous posts on the matter! :-) You seem to suggest in your second sentence that only 8pcs of 16MB SIMMs can be used in the SE/30. Not sure about the meaning of "If you only have 4x 16MB SIMMs" because in the second half of that second...

Thanks, Kai. Well, I don't have that kind to test. But if anyone should know if a PAL SIMM can work at all in an SE/30 it would be @Zane Kaminski, seeing that Garrett's Workshop created them! https://www.tindie.com/products/garrettswrkshp/gw4194a-4x4mb-pal-simm-ram-for-mac-ii-and-iix/...

Thanks, Eric. I actually was using the OS 8.1 driver prior to the Dec. 2022 firmware update, but if I recall correctly, I had issues with my Mac SE, which forced me to reverted the drivers back to v7.3.5, async in order to retain the broadest 68K Mac compatibility. It tend to swap my BlueSCSI...

Thank you for making time to share your thoughts. Through the years, I've not read any stories about the SE/30 having issues with 16MB SIMMs, but I will admit that so few people seem to have them that the data pool is rather small. Below is a graphic I extracted from an old book on Mac...
