Same system, 640x480 256 colors, but booted from the OpenRetroSCSI 7.5.3 image. There does appear to be a bit of performance improvement on 8.5. The other guy was running at higher resolution which probably slowed the scrolling down slightly too. pi-86k: 100: 0.07 1000: 1.88 3000: 13.17...

No L2 cache, but the system RAM is 2x32M 60ns EDO sticks

I'll check for a cache simm tomorrow, but if draw speed is a factor it could be the video card. I'm using the DB15 on a card not the on-board video because I don't have the adapter cable for it. System Profiler lists it as an integrated vram card, where I presume the on board would be sharing...

i finally got an ADB Wombat so I can type on my 7100/66 running System 8.5. PPC 601 @ 66MHz pi-86k: 100: 0.07 1000: 1.85 3000: 13.12 pi-ppc: 100: 0.03 1000: 0.53 3000: 4.10 pi-pwr: 100: 0.02 1000: 0.48 3000: 3.80

@Garth Beagle Just posted a short showing those in action the other day:

From what I understand of that cap it comes from the ROM being mapped starting at the 10MB address and thus expecting to from functions to be in that range. Moving it would be a serious reengineering of the ROM and potentially breaking some apps that naughtily call into the ROM directly. The...

4 State Machines per PIO unit, and two PIO units. Since I don't think your state machines need to signal each other directly then you can probably use all 8 for ADB.

I had a batch of these printed up in nylon resin to fix some broken keys on a Ti99/4a keyboard and they seem to fit really well. Endorsed. I have a dozen or so extras I can stick in an envelope if anyone needs them.

The ADDRESS signals will run to multiple ICs but exactly how they get there isn't important on a schematic. On the schematic you'll see ADDRESS come in and some subset of the signals (A0 - A31) connect to pins on a chip. ADDRESS A0 anywhere in the schematic should be connected to ADDRESS A0...

That's the schematic shorthand for saying those all stay together as a 32-bit wide bus rather than drawing out all 32 everywhere.

Linux isn't going to fall for those OF shenanigans, OS9 probably will be so try flashing from there. Linux re-probes the PCI bus itself so it's going to pull up the 6112 ID again. I think that 6112 ID is a red herring. The main ID is still 3112, it's the subsystem device ID that's 6112 (aka RAID...

Correction; Most of the magazines are Communications of the ACM, with 5 issues of ACM Queue mixed in. It's an almost complete set from September 2007 to October 2013. Only April 2010 seems to be missing. The 43 issues of IEEE Computer look to go from May 2008 to March 2012. 4 of the ACMs have...

It shouldn't be a big deal. WiFi is ethernet over an invisible wire. The association and authentication can be handled by and hidden by the Pico and just expose the ethernet layer to the Mac. It's been done by dumb Wifi-ethernet bridge devices for as long as there has been WIFI. Longer even as...

Nah. There's a whole second CPU core on the Pico currently unused that can babysit the WiFi.

Dynaport emulation would probably be the easiest feature to start with because the Pico would be doing any processing, just passing packets in and out. Maybe with a WiFi configuration utility added to the Toolkit eventually. That depend on the underlying Pico libraries getting WiFi working...

I picked up a selection of ISA & PCI expansion cards from somebody this evening and they had a box full of IEEE Computer magazines from the early 2010s. Print magazines aren't my bag but I can act as an intermediary if someone wants them. My example photo was worse than I expected but you can...

I happened to have picked up an Adaptec 29160 card a couple of weeks ago, it should be the single-channel version of your dual-channel 39160. I slapped it into the G5 I have out of storage and plugged in one of those BiTMICRO SCSI SSD's that popped up last month. Sorbet Leopard booted without...

There's a PowerDomain Control Utility for slightly older cards that's can flash the firmware on those cards so I'd say that it's a good chance that you can flash in place in the Quicksilver. Oh, there's a PowerDomain 39160 Flash Utility for Mac as well so I think you have an excellent chance of...

Oh, I also printed a "hook" to hang he dog's leash that is shaped like the back end of a dog. The leash hangs from it's tail.

I recreated the plastic brackets that hold the retaining bars that keeps things from falling out of the door shelves on my fridge. That was maybe like 20g of plastic that went to something useful out of the 5+ kilos of junk I've printed.
