This is the stock MC88920? Replacing with MC88916 like this would be need go hit higher speeds? https://www.ebay.com/itm/135168460410 https://68kmla.org/bb/index.php?threads/upgrade-mc88920-to-mc88916-for-lc475-p475-q605-advanced-soldering.48616/

I've had the same experience. I've wondered if it has something to do with the tolerances of the RAM and/or VRAM I'm using.

Thanks. I bought a custom ROM SIMM years ago or my IIsi which I had forgotten the particulars of, it is is a GG Labs SIMM! Its really not doing much in my IIsi other than making is possible to boot from ROM for fun (or if the HD dies, needs troubleshooting...) so I think I will move it over to...

From: https://68kmla.org/bb/index.php?threads/different-rom-se-30.50996/post-574603 In anticipation of receiving a socketed Booster v2 from you (thanks!) I'm trying to make sure I understand how best to make use of the ROM booster feature. Hardware wise there is a jumper for enabling ROM...

Do you have a PRAM battery installed? I'm pretty sure the LC475 is unique in that form factor in needing a working PRAM battery for video to work. I think folks have some luck with quickly turning the power supply switch on, off, and on again to sort of jump start it without a battery.

You also might want to take a look at this thread for another option: https://68kmla.org/bb/index.php?threads/replacement-power-supply-in-quadra-605.41793/

I believe the stock LC power supplies are between 3.25A and 4.75A for 5V so 2A might not be enough. They are 0.75A to 1A for 12V so 2A should be more than enough there. There is the "POWER UP PIZZA" from CayMac, I built one recently, sourcing the Mean Well power supply modules from mouser...

That jibes with what I see under Mac OS 8.6 but not 7.5, there I see the "leftmost" icon, not your new icon. Could this be because my 7.5 machine is doing AFP over AppleTalk and the 8.6 one is doing AFP over TCP/IP?

Very Interesting! One thing though, from my screenshoots above it looks like Mac OS 8.6 is displaying the custom icon from the AppleShare volume (not ignoring it in favor of the Finder's own default icons). Maybe Mac OS 8 unintentionally did this (bug that was subsequently fixed)? Or was this in...

Thanks for the reply, I should have found the "volume name" thing, doh! The Netatalk progress has been amazing, I did find the answers to so many of my questions in the docs (got Webmin working for example), thank you for all your hard work! On the icons I totally get it, makes sense (even if I...

Working on retiring my MacIPRpi 5 home retro server in favor of a "new" MacIPRpi 6 one. Have them set up in parallel at the moment and pretty much everything moved over and working with one cosmetic thing bugging me, the AppleTalk share name and icon. Not sure how to control the...

Found an old thread that appears related you might want to check out and/or resurrect: https://68kmla.org/bb/index.php?threads/this-disk-is-unreadable.26123/

The icon in that error message appears to be representing an external floppy disk drive, do you have one of those connected? If not something is making your Mac think that you do? ...or maybe that dialog icon is used for external removable SCSI drives, I take it you don;t have one of those...

So awesome, thank you!!!

Just posted to Macintosh Garden: https://macintoshgarden.org/apps/supermac-marketing-tool-kit-vol-1 Looks like some neat stuff although you need period (1991) versions of Pagemaker, Persuasion, etc. to open the contents.

Unfortunately I do not :-( (I have originals of discs 3, 5, and 6 v1.1) @MrFahrenheit would you happen to have an original of "Apple Restoration CD - System Software Disk 1 (September 1994)"?

So before I get to trying a CPU upgrade I needed a hard disk since the original was missing. Since the bundled Adaptec 2930BU SCSI card (AHA-2930B MAC) card supports Ultra SCSI, 20MB/s I wanted to make use of that if I could. From the Read Me: Fortuitously, BlueSCSI and ZuluSCSI recently...

Like @Garrett B I also have a recapped IIsi/Sony PS exhibiting this same behavior. In my case maybe ~20% of the time the Shutdown DOES stick and it doesn't start up again. One thing I wondered (coming from a place of zero real understanding of how this all works) was if what looks like a little...

Thanks guys!!!
