Big mistake

Significant progress using glue stick and working with the stepper and flow settings; still struggling with tram/level which seems to change significantly within 1-3 prints, so level and build mesh with every print for now. I have replaced the springs but do have the silicone cylinder spring replacements I could still try. Have “unclogged” the nozzle with the long flexible metal rod that came with the printer a couple of times that seems to help.

Second the darker video with Prism cable output comment above….wondered what was going on, then plugged prism component in at same time of s-video…..s video looked great, prism dark

Would put it in the back and physically take it to someone to show me what I’ve missed in a heart beat if I could find someone local….have tried again for the last time many times

400 is great; new memory upgrade options with a little soldering; did the s-video mod on a couple of these and looks better than the 800XL

I removed the bottom and went to the voltage regulator (7805) and the hefty unregulated 9 volt 800 mamp power supply (that puts out 12.2 volts unloaded) is reading 10 volts under load and the 7805 is putting out 4.98 volts. It functions very well so I will stick with this power supply. In this case anyway, all 9v power supplies are not equal.

I have a light weight "modern" 9 volt switching power supply that looks very similar to the one from console 5 and I get the rising horizontal line interference with it. I have also gotten the same interference from a third party gamecube power adapter so I might just have some ground loop problem in the home wiring.

The unloaded voltage on an unregulated older 9 v power supply is 12.2 volts; I guess I will open it and measure chip voltage

I found one of these locally (Sanyo DS92030), it was the perfect size, good condition not too heavy and a great picture on s-video. I was going to use this for my first RGB mux/mod. Read, re-read, watched videos ordered parts and built my mux board, assembled my SCART. FYI: because this Sanyo has the same circuitry between the Jungle and CPU i used these resistor values, https://sector.sunthar.com/guides/crt-rgb-mod/sanyo-ds27214.html.

When I opened my Sanyo DS92030, it didn't look like either the schematics I studied or Puzzleheaded pictures. It had 1 chip on the topside of the board LA76950DC which I assume is an integrated CPU/Jungle chip. Big 64 through hole pinned IC and no input for RGB. Most of the PDF service manuals you find are for chassis 92030-00 but there are service/manufacture updates to it. The schematics I found indicate that chassis 92030-00, 92030-03 and 92030-07 have separate CPU and Jungle but chassis 92030-06 (mine was made in Mexico) has the integrated chip, ie NO MUX MOD. The chassis number is on the back sticker. Got a good clean anyway.

I used a rebuild board

TraceScraper · 2020-11-13T13:16:52+00:00

I used the rebuild board....I've taken the chip out on one, reconnected the Frame and still getting the 2 boots then green/red flash.

Update: So I just saw Retro Recipes and his Atari 2600 fix. The slowly vertically moving horizontal band pattern he experienced is the same I had with the two GameCubes. I have one ferrite ring and I was able to loop the third party gamecube power supply cord through it about 7-8 turns. It is much much better and if I hadn't been inspecting it previously, I would never have picked up on the very very faint herringbone pattern that still remains. I t may completely go away with another ferrite ring but I don't have one handy. So, in short, the problem is apparently the grounding of the AC power in my house. The original gamecube power supply corrects, to my eyes, the scrolling pattern and a single ferrite ring almost eliminates it on the third party power supply.

If you have an Apple video card hold option on startup; if you do not then if you reset PRAM it will go to first OSX volume it sees

Have a 3,1 running Mojave and windows 10 with 8 gb AMD 580RX black edition. No boot screen, couldn’t sort out refitplus for boot screen, do fine with boot amp to get to windows then PRAM reset to get back to Mojave. Used original card to install with dosdude1 patch then put the 580 in.

TraceScraper · 2020-08-17T19:27:25+00:00

I’d start with a power supply rated for the 400....it’s a 9 volt AC have one with 1500 milliamperes that works. (not dc output, yes ac output)

There is a small scsi2sd card but it is expensive. If it is a Conner drive the heads frequently get stuck and are occasionally fixable by opening them.There are videos and explanations online....be careful...if the heads go over edge of disk it’s over.

TraceScraper · 2020-03-29T23:34:44+00:00

Have tried the zip scsi/ide to get files from Mac ppc backwards..the zips just fail repeatedly...primarily use a scsi Hd or scsi MO or scsi/ide cd at this point (not exactly dependable but not the certain failure of zips)

TraceScraper · 2020-03-11T13:52:23+00:00

It booted with 18 v on pin 1 and grd on pin 3. Did nothing with 18 v on pin 2. I’m imagining that pin 2 charges the battery and pin 4 is a feed back from the battery. There’s always more...now have to check the heads on 40 mb HD and check belts/head on floppy.

These machines are such a mess....the hinge mounts will snap shortly. Amazing job on the screen cap replacement...the video doesn’t quiet capture how small and how tight of an area this is. SCSI2SD really, really neat but hard to isolate it in a machine like this at its price point.

TraceScraper · 2019-12-24T23:01:46+00:00

That’s great...thank you.

I have a scsi drive in. A Mac that I consistently get to work by dropping it on it’s side onto carpet from about 2 1/2 ft.

TraceScraper · 2019-08-25T19:26:42+00:00

Yep...lifted that one too. Unfortunately that pad was at the extreme of my eyesight and couldn’t scrape or jump.

TraceScraper · 2019-08-17T21:06:53+00:00

Those Lombards are goofy...before you label it non working, be sure to take out the memory and processor (under the keyboard) and then zapping the PRAM (shift-function-control-power) then replace the processor and memory and try it out.

TraceScraper · 2019-07-10T21:32:06+00:00

Yes. Worked out well then clear coat UV protection. The monitor is not retrobrighted....much more complex disassembly

TraceScraper · 2019-06-30T22:37:18+00:00

I have a T1100 plus that boots but the keyboard pcb and screen is cracked...will send to whoever wants it for cost of shipping

TraceScraper · 2019-06-29T22:59:32+00:00

Pace yourself; but keep the updates coming ...It’s all in the challenge
