You can use any windows USB keyboard. Use the keys Windows+CTRL+P+R. If that does not do it, try Windows+ALT+P+R.

Try power up, hold down Command+Option+P+R and wait for 3 full chime loops. If you don't see any video life by then, release and hold down the option key for a good few minutes. What type of external video ports are on the video card?

Here are the photos of 3400c memory expansion cards: 64MB From my CL 3400c post And 16MB From my CL 3400c post The 190/5300 has the same connector, but in 180 degree orientation. Your item on the left (P20936) appears to be for 3400c and the one on the right (L3596) appears to be for 190/5300

The last memory picture before the video adapters appears to be two PowerBook memory expansion cards. Possibly 190/5300 or 3400 series.

Day 37 (part 2) My CF-IDE carrier finished, I installed it into the drive carrier in the PB190cs. Assembled the rest, epoxy seems to be holding. LETS WRAP THIS CHALLENGE UP! So, at the last minute, the PB190cs would not boot. The 3rd G3 500MHz that was flaky, was flaky again. After the...

Day 37 The epoxy on the PowerBook 190cs repairs has hardened a little more... maybe enough to assemble everything and see what holds. Starting with the screen, the speaker mount (steel strap) was missing. I found a piece of thin flexible grounding/shield metal and cut a strip and drilled two...

Day 35-36 Let's end this month with a couple failures (or call them redo projects for the future). First, the PowerBook 190cs epoxy fixes: the epoxy was mixed and applied three days ago. It is still a little gooey like a hard taffy. I was able to remove the clay molds from the bottom but...

EveryMac shows it should do 6GB... Have you zapped PRAM (CMD-Option-P-R) for 3 chimes before booting? Have you reset SMC?

Day 34 I finished soldering up the last of the 5 Mini-Amps I built for my Apple Pro Speakers. Three white, one black, one natural (semi-clear). They are all a little bit different and unique (random screws, different power plugs, etc). More soldering. My bodge wire arrived, so I dove into...

I filled in the form from their website and requested contact with the site owner. Left a message, we will see what happens.

"Email us at PCSupport any time or use the form below." Circa 2010. Last forum capture was 2019.

Last pull from the wayback machine that still has their sales website active is from July 2024, so they have been shutdown for 6 months. Maybe you can harvest the contact form there or see if there are any other email links.

Day 33 I spent this morning working on the PowerBook 190cs. Today is an attempt to fix some of the aged plastic and the broken points. The back of the LCD bezel had four failure points. Two of the failure points: I don't think I can repair the lower hook tabs. The other two failure points...

Day 32 I have been soldering up and completing some amps for my Apple Pro Speakers. 3 complete, 2 to finish yet. How the light shines through on the different colored cases. I am currently working on creating some controlled molds and forms to hold the epoxy I intend to put on the...

Day 31 (part 2) It's a Friday night, so I stayed up later than I should... Working on the 190cs battery terminal repair. De-soldered the connector from the motherboard, soaked it in white vinegar for a couple hours with intermittent agitation. Then I bathed it in IPA to cancel the vinegar...

Day 31 I finished installing 7.6 on the PowerBook 190cs. System info: I bought another PowerBook G4 15" 1.5GHz off eBay plus delivery for $20 total. Arrived just today. It was listed as "no post to bios" and "water damage and pressure points on the screen." Screen looks fine except for a...

Congrats on finally figuring out that G5 SSD issue!
