The EVT board for BlueSCSI Ultra Wide SCA arrived today (and this time the PCB was the right color!) Already working with the standard Ultra Wide firmware, and now I get to implement SCA SCSI ID detection.

The Fast20 Overclock is likely to provide similar speeds on BlueSCSI v2 50-pin. But on v2 it's definitely an "overclock", pushing things further and harder than they were originally designed to go from an electrical design perspective. BlueSCSI Ultra is better electrically, with more closely...

With Wide SCSI, I believe the internal and external 68 pin cable ends are identical. This connector plugs into my internal Wide SCSI cable just fine. As mentioned in the announcement, we're seeing 30+ megabyte per second read speeds with some systems and SD cards. This is very system and SD...

This little banner should be present at the top right of the site root (just tinkerdifferent.com, not viewing a forum thread or subforum). That's all the notice we have currently about where to donate. Currently we lack some experience in figuring out how to make the button appear anywhere...

This RC build has resulted in my fastest benchmark yet on a PowerMac 7300 with Atto ExpressPCI PSC SCSI card. 17.554MB/sec read, and 7.513MB/sec write.

Given that there were only two nominations (trag and jdmcs) and three open Board positions, voting wasn't necessary in this case. To @trag we extend a welcome to the Board, and we welcome back @jdmcs to the Board for his second term. We will be reaching out to figure out scheduling for the...

Echoes of "ELNA Long Life Capacitors" perhaps

With help from Greiman of course. He provided a generic RP2040 SDIO implementation which made a lot more sense than what was already in use. My main contribution was cutting down the number of PIO instructions it required and hooking it into the existing framework.

These are the 5300 model number, so I would presume they don't work in the 190. The back of the box shows that the 190 model has a different part number, so it's probably something like the onboard ROM is different between the two.

Another "New Old Stock" product has been added to my store, the Focus Enhancements LapisColor MV16-EN for PowerBook 5300. That's quite a mouthful. This expansion card gives you both an external display output *and* ethernet on the same card - pretty cool if you ask me. A version of this card...

Generally speaking, you always want to replace the SMD and through-hole capacitors on a Portable motherboard. They are one of the largest sources of trouble because they basically always leak. So that's priority #1. The non-backlit doesn't like to turn on from just the power adapter - it's...
