Yes to "inflame" is an intensifier. It doesn't mean to cool down. Understandable mistake though for people learning the language. Those tiny baby AT cases that were so popular at one time are not only difficult to work in (I have one where you can't replace the memory without physically removing …

So, choose 1.5x and 66MHz and you should get 233MHz even if BIOS can't figure it out. This. Thank you, I got the 233 MHz readout. While I was at it, I upgraded the CPU cooler and installed a custom, brushless fan of high quality. It is a bit loud but I don't mind ;) Also, I picked up a P133 with a …

When I read that, it opened a vague memory of this in my mind. Not enough to pin it down and be sure, but something just on the edge of being familiar. I tried different combinations of the multipliers (even ones that weren't explicitly listed in the manual, I got weird speeds like 110MHz and 180MHz …

Re: (Solved) What kind of cache memory is this?

I've seen this technique used on DIP type cache chips. Hell, I've even seen offset BIOS chips. It seems that your chips are 3.3v, whereas from what I gather mine need to be 5v. Thanks for digging that up though, I might actually have a use for the 3.3v chips as I just came across something …

Hey quicknick! :D Upon closer inspection (the previous pic was from the seller), it clearly says 32kx8 on the board, in two banks. The jumpers are also labelled very well. I really like the attention to detail in this machine! All the cache sockets are 28 pin, but the TAG chip is a 32 pin SOJ. …

WIthout having any manual for this machine, could you tell me what chips you're using? This one seems to mean to me that 128k is found in each chip, and I will need 8 of them, for a total of 1,024 (seems excessive) https://www.ebay.ca/itm/QTY-20-TC558128AJ-20-TOSHIBA-SOJ-32-128Kx8-CACHE-SRAM-NOS-1- …

Hello, I just got a nice Siemens 486 and I would like to know if these are cache memory slots (it seems they are, there are 8 + 1 for parity, and they're next to a jumper labelled 128k/256k) What kind of chips go in these sockets? If they are indeed cache chips, where can I get 256k's worth of SRAM? …

I'm curious to know how many here wear corrective lenses that grew up with CRTs vs LCDs and rampant smartphone use. I'm 36 and AFAIK my vision is quite good.

486GIO-VT motherboard not POSTing (actually, not doing much of anything)

Hello all, So I got this 486GIO-VT mainboard in a computer. It had no CPU, just a video card and some RAM. I put in a working DX2/50 (Intel) and configured the board as best I could (the instructions here are confusing: https://stason.org/TULARC/pc/motherboards/F/FIRST-INTERNATIONAL-COMPUTER-INC-486 …
