who was the seller? when I search for UB141X03 on ebay I get lots of interesting results. looks like that panel was used in IBM/Lenovo laptops too... ?
A local seller is offering a Power Mac G3 in working condition for $50. This is the original beige desktop model, with built-in ZIP drive. Never had one of these BITD, instead opting for the cheaper iMac back then. But looking at it now, it looks pretty cool with PCI slots, CD, floppy, and ZIP...
These Macs are particularly finicky and difficult. I'll be starting a recap of a 5120 tomorrow. Removed all the caps today and cleaned everything. What a mess! Wish me luck. :)
Just another thumbs up for Meguiar's PlastX. It is gentle but really polishes plastic nicely. great product. I've used it on the exterior of a Cube and it took the fine scratches and shined it right up.
It might be possible to design an all-internal solution using a Pico-PSU and simple AC-DC open frame PSU. I did one these a year or so ago for the Sharp X68000 and it works great and looks stock. Someone could easily adapt it for a Mac.
If anyone is seriously interested in developing an FPGA Mac, I would recommend the MiSTer project which uses a pretty cheap ($110) off-the-shelf Terasic DE-10 nano that has a Cyclone V FPGA and dual core ARM with shared SDRAM and plenty of GPIO. The MiSTer community provides additional SRAM...
While it's not a super capable Mac, the MiSTer (FPGA console) project does have a Mac Plus core available: https://github.com/MiSTer-devel/MacPlus_MiSTer
I've played around with it and it works OK. It needs someone who (a) knows VHDL and (b) loves the Mac to continue work on it.
Just picked up a 1400c with (you guessed it) dead PRAM batteries. I've ordered some replacement VL2330 cells and will attempt a replacement. Tearing the 1400c down wasn't that bad actually. Just be sure to get a decent spudger with a flat end for prying apart the monitor hinge brackets.
So I found a working SE and swapped main boards. The broken SE (now affectionately known as old stripey) works fine with the working main board. So the horizontal stripes is something on old stripey's main board. I swapped the ROMs and still no luck. So it must be some other component on the...
I would get a SCSI2SD, prep it with an SD card of appropriate size and connect it to the external SCSI port. Format the "drive" and copy everything over. Remove the spinning HDD and mount the SCSI2SD inside.
Well, I figured out why I was getting a black screen when only 2 SIMMs were installed. My SE logic board has the 150 ohm resistors at R35 and R36. On my board, R35 was cut and R36 was removed. I soldered 150 ohm resistor on R36 and put 2 SIMMs into slots 1 and 2 and instead of a black screen, I...
I cleaned the SIMMs and sockets. This SE has 4MB of RAM (4 X 1MB SIMMs). With the 4 SIMMs installed, I get the horizontal lines.
I removed the 2 SIMMs from slots 3 and 4 so it only has 2MB of RAM and I get a black screen. Swapping the 4 SIMMs around so that only the 1st 2 slots are filled...
I had a similar problem on a Plus and it was a cold solder joint on the analog board where the power molex connects. I simply reflowed the solder on the analog board for the molex connector and all was good. YMMV. :)
I have an SE that when powered on does not make a chime and displays these lovely horizontal lines. Initial inspection of the motherboard looks good. Anyone familiar with these symptoms? Gonna check voltages next. Thanks!
