After over clocking my LC III, I added a heatsink to the 68030. No extra fan. It is running just fine. The temperature is about 130-140°F on the heatsink. I have put it through a battery of the Speedometer benchmarks without any issues.
I bought one off eBay and it came in that black plastic packaging, but it *appears* to be legitimate. I paid around $30.
It passes the Speedometer tests with flying colors. I ran 100 iterations of the "Benchmark Mix," and 100 iterations of the FPU benchmark.
The numbers are as follows...
ORDERED. Congratulations.
Now someone just needs to make a strong case or a short dongle for this thing, as folks are liable to snap it off or stress out the connectors from the weight of sagging VGA cables.
It appears to be working without any trouble with a Waveshare monitor designed for a Raspberry Pi, which supports up to 1024x768 but is doing internal scaling to fit the LCD. I have a DB15-VGA dongle designed to emulate Apple monitors.
When I bought the computer the previous owner must have...
Sure, here are several photos. I just noticed that the board says PrecisionColor 8-24X dated 1991, but there is a ROM chip installed on the end marked:
1993 RADIUS INC
PREC CLR 24XK
V1.42 256K
U1200 -0053-04A
Resurrecting this thread. I bought a Quadra 650 on eBay last month for #Marchintosh and GlobalTalk 2024, and it had a Radius card inside. It's identified as a PrecisionColor 8/24 on the board, and it supports 16 million colors @ 1024x768, but the Radius control panel said it is a...
When the instructions say to "remove" this resistor R14, does that mean to leave the pads empty, or bridge them with a jumper wire?
God, this brings back memories. I remember doing something similar with a Texas Instruments calculator in high school. There was a similar modification you could...
I have a Farallon Ethernet card installed in my LC III, and I am considering this mod as well.
The gap between the top of the Motorola and the side of the NIC facing the CPU is about 1/2".
To account for fit with other Ethernet cards, ensure adequate airflow around the heatsink, account for...
I had a similar issue on a Quadra 650 I just bought last week. I have a BlueSCSI. whenever it was plugged in, the computer would hang.
After a few minutes of pondering, I realized it might possibly be a SCSI ID conflict, because prior to this, all the computers I have been using with a...
Bumping the topic because this is a great tip, and may be helpful during #Marchintosh and the renewed interest in vintage computing.
I had this problem recently on an LC with a 12" Apple RGB monitor, where some glitch in Finder allowed me to drag a window above the menu bar, rendering it...
The presence of the extra interface without a physical connection (or any way to talk to the network) meant that the desktop would never load. I had the same issue when I moved the LC and forgot to reconnect the Ethernet cable to the internal card.
Purging the driver from the system file...
No, sir. I created a new one from scratch and re-entered all 70+ IP addresses from the GlobalTalk spreadsheet by hand. (Why oh why isn't there a keyboard shortcut for the "Add" button, or a way to press Tab to select it?)
I'm more certain that it's the leftover driver because, when I...
