Re: Olivetti PCS33 (386 SX)/M-300 - Repairing
Posted on 2021-10-31, 10:48
Thought I'd reply here to ask, since it's related to the Olivetti - I moved my PCS-11 tonight and must have accidentally knocked the battery out. I reseated the battery + speaker and reconfigured the BIOS. But for some bizarre reason, the CPU is stuck at 8MHz instead of 16MHz. Any of you know what …

I have recently recovered this card SuperMicro 370DLE https://www.supermicro.com/products/motherboard/P3/LE/P3TDLE.cfm I'm waiting for the rams.

it is a hypothesis of a circuit, the photo is blurred and it is not possible to follow the tracks

the 37c65 chip needs a 16 Mhz clock on PIN 23 and it is certainly generated by the nearby components (74LS04 + the resistors and capacitors) check on the 74LS04 pins if there is a signal

the 37c65 chip (floppy controller) is missing or did you remove it to check the tracks?

With the system on I don't get any frequency readings across the two legs of the oscillator, and my meter can read up to 60mhz. Is that more or less the proper way to read frequency on an oscillator, just directly across the legs? Basically a short circuit due to battery corrosion burnt the 12v …

Other than the fact that they are cheap, I don't understand why people keep using the flash card-2-whatever adapters. The proper choice for a PC would be an IDE flash module like what you'd find in this list of Amazon stuff.... https://www.amazon.com/s?k=IDE+flash+module&i=electronics&ref=nb_sb_ …

Where do people hunt for old video cards in Australia? I did a search on ebay.com.au and the options were limited. I could only find one reasonably priced GF4 MX440 and a Radeon 7500 worthy of buying. In Australia you have to ask Ben ,,, before he destroys every computer on Australian soil https:// …
