I'm glad I have the same ROM/OS configuration as yours. But I'm seeing frequent instability from MacBench. For example, it always fails to save the results file completely and choosing to quit without saving always hangs the OS! But here's my result: And that's as bad as yours! Checking the...

I recently upgraded my SE/30 from a BlueSCSi v1 to v2 with PICO-W for DaynaPort Wifi. Subjectively, the disk performance does seem poor. I'm attempting to run MacBench 3.0. So far though, I've seen a failure and a hang .. but I'll keep trying. Note, however, that my machine isn't stock and...

Good to see A/UX live on. I installed A/UX 3.1 on my IIcx some years ago and have since carried it forward to IIci, SE/30, Q700 and Q650. It's somewhat pokey on pre-Quadra machines and the MacOS side is rather hampered by being only 7.0.1. But in its day, it was super-impressive. And many of its...

Sorry I missed this .. I used to do this regularly. It's a manual process that's straightforward but does require some precision. Here's what you need to do: If you haven't already, get a copy of the SCSI2SD User Manual from https://www.codesrc.com/mediawiki/index.php/SCSI2SD_UserManual and the...

I'd brought an SE/30 back from the dead: replaced the vacuum-less CRT and assorted video components, recapped, added 64MB RAM, installed 32-bit ROM and BlueSCSI. It now runs MacOS7.6, A/UX, and NetBSD-3. Nice machine, but only serial networking. TCP/IP over LocalTalk is possible but it’s slow...

I've been longing to replace the MacBook4,1 that I'd foolishly recycled years ago, so I acquired a cheap, semi-functional unit and restored it. It needed only a hard-drive, a new battery and a RAM upgrade to 4GB. It's a bit more battered than my original pristine machine .. but its perfectly...

Several years ago, I repaired my API1PC36 REV:A PSU using badcaps.net resources. For me, it turned out to be a starter cap in the primary circuit. https://www.badcaps.net/forum/troub...4-mdd-acbel-power-supply-issues-api1pc36-400w Watch out for the high voltage that doesn't decay too quickly...

I have the same MDD PowerMac3,6 as yours. I've had it from new. Apart from the loud and hot PSU, which failed once and needed recapping, it's a fine machine. I multi-boot OS9, OSX Cheetah, Panther, Tiger and Leopard plus NetBSD-9 and Debian-8. I configure yaboot from Linux for the...

There must be some variability though I've not not seen any. If you're not satisfied, get in touch with them since I know they have good customer support and returns.

Strange. I very recently installed 4 x 16MB of the OWC SIMMs in my SE/30 without issue. And I also use these in cx, ci and q700. In what way don't they fit?

CPU usage is 100% for early macOS versions. Prior to pre-emptive scheduling, most things was polled for and so the processor was always busy. macOS 8 introduced pre-emption and multi-threading among some blocking system services, but applications still needed to co-operate! It's instructive to...

My dead cache card also caused the machine to hang with a gray screen after giving a good boot chime. This card had bad tag cache SRAM chips which I successfully replaced. This 3-tone chime may indicate something else wrong with the card -- like a bad data SARM chips or the main ASIC. Since the...

I suggest subscribing to the YouTube channels of at least JDW, Mac84 and Branchus Creations, and catching up on back-issues. There's a lot of nonsense amongst the good stuff .. but much of the nonsense is good stuff too!

I've used a Beige G3 as a bridge machine. It's a popular choice which runs OSX Tiger - but also boot into Classic macOS 9.2. I use ftp or Safari to download from the web and then use AFP over AppleTalk on ethernet to send files to older machines. You need to run AppleShare 3.8.3 on the target...

Hah. On re-checking my work, I found some unconnected pins on TAG SRAM chips. My SMD soldering is flaky and I'd been so fixated with checking for bridged pins that I'd not checked for missed pins. With this fixed, the card works fine and passes its diag in MacText Pro. Victory!

Three replacement (used) Cypress chips arrived from China. All tested good on the TL866, so I installed them and plugged in the card. And the machine booted! But the cache isn't functional and, in fact, slows the machine a little. :( Usual diagnostics (like Snooper) don't seem to recognize or...

Mine's a slightly newer SyncMaster T200HD -- which is basically a TV and is fine for my PPC machines with later VGA and DVI but seems to lack coverage for graphics modes of the early Macs.

This startup circuit is relatively straightforward but prone to so many failures. After recapping a badly electrolyte-scarred board, I had a situation where things worked but the machine was left connected to power but soft-shut-down for a day or so, it would refuse to soft-start. I replaced...

I too have a non-functional Iici cache card that I'm debugging. Same failure mode at boot. It's SRAM chips are: CY7C128A-20VC 2kx8 24-pin TAG SRAM MT5C6408DJ-15 8kx8 28-pin SRAM I also have a good cache card which uses: MT5C1608DJ-20 2kx8 24-pin TAG SRAM CY7C185A-25VC 8kx8 28-pin SRAM...

I’m glad your machine checks out. There may be a dependency on the tantalums used. For the record, my misbehaving cap was a Kemet from Digikey - here’s the part info:
