The IIsi arrived super well packed, thick bubble wrap cocoon, but something was rattling inside... and yep it was the Turbo 040 card! Ugh. Must have shook loose during shipping. (Note to self, remember this for future shipping instructions to sellers...) I put it in my known good IIsi, crossed my fingers and yep it booted right up, noticeably faster... The Happy Mac boot icon has a little “Turbo 040” marking now! I installed the DayStar QuadControl Control Panel and it’s a 33Mhz model with 128KB cache, firmware 4.01.

It's amazing the IPS improvement of the 040 over the 030. Nice catch! Quote Link to post Share on other sites
Fizzbinn Posted July 30, 2020 Author Report Share Posted July 30, 2020 (edited) So I tested my new Turbo 040 using my known good IIsi with its known good DayStar PDS to Cache slot and PDS pass through adapter card. The similar adapter card that came in the “new” IIsi had a problem, a missing capacitor on the back of the card that I found under the floppy drive... Top - my good adapter, bottom the new one: The broken off capacitor next to the damaged pad: Zoomed in: And my repair: I used a smaller package size 10uf capacitor since it’s what I had but since one of the pads was lifted/snapped off with the wrecked capacitor and I had to use a wire from the via to the pad it didn’t really mater. Swapped it in and everything seems to be working/good! One thing I’m excited about with the new adapter is it’s Cache connector is offset/set back which means I can use an Asante Ethernet PDS card and it’s rear external port board (which is blocked when using the other adapter board with aligned Cache and PDS pass through connectors.

Fizzbinn Posted December 7, 2020 Author Report Share Posted December 7, 2020 (edited) I found a Centris 610 on eBay that looked to have something interesting inside, a Sonnet QuadDoubler. I jumped on it just for the QuadDoubler, thinking it might be a great upgrade for my 605 or 700. I hadn’t looked at/thought about these case style Macs much but they are actually somewhat interesting on their own. I just wish they had soft power, I guess I give the 605 a pass due to its smaller size? True to the description it wouldn’t boot, start up chimes followed by death chimes. I spent the a bunch of the weekend cleaning up the motherboard, re-soldering some chips with loose pin legs, and recapping. As I have to remind myself happens sometimes this all turned out to be for naught, startup behavior unchanged. Edited December 7, 2020 by Fizzbinn Quote Link to post Share on other sites
Fizzbinn Posted December 7, 2020 Author Report Share Posted December 7, 2020 With the Centris 610 down for the count I gave the QuadDoubler a try in my 605. ...and it booted just fine, 50MHz! Things seemed good and then after 15 min or so, crash. Overheating likely since it’s probably only meant to run at 40Mhz (2x20Mhz speed of the C610). As a test I moved the case fan on top of the heat sync and it seems stable now. I’d need to figure out a better solution make this work longer term (be able to close the case). But oh so snappy!

jessenator Posted December 7, 2020 Report Share Posted December 7, 2020 (edited) Bummer about the 610. Seems this form factor us reaching its halflife of sorts, what with the problems posted so specifically about this board. Any luck testing the QuadDoubler in another machine? Edit :Ha! Simulpost Or so I thought. Oh well. Nice numbers! Edited December 7, 2020 by jessenator Quote Link to post Share on other sites

Fizzbinn Posted January 1 Author Report Share Posted January 1 So picked this 68040 upgrade card up on eBay BIN (with an Dayna PDS Ethernet card) for $61 shipped: Anyone know anything about these? Applied Engineering Transwarp/TW 6400 from 1993. Looks like it’s 33MHz, didn’t have a pic of the other side, wonder if there is an optional cache module? Googling doesn’t really turn up much, info or driver wise.... Quote Link to post Share on other sites
