Your motherboard only supports FPM RAM. Are the 30-pin modules EDO as well? http://www.elhvb.com/webhq/models/486vlb3/sis471b.htm

I can see the Xeon Phi being collectable when better/faster models hit the market.

I didn't get anything done today (that's not unusual for me). Got a CT2230 (SB16) Revision 49432 (the latest and best revision) to add to the system. I have visitors Sunday PM, but hope to be up to working on it in the evening.

Just got a SB16 CT2230 Revision 49432 (the last and best revision). Need to find a CT1748A chip to fit in the socket. It looks a lot better than the photo 😀 This will be going in the 486 build I'm working on, with Win 95 OSR 2.1

Thanks. I just changed the voltage setting.

Hoping that I have a nic that Win 95 has drivers for, so I can get online with it (or at least see my main PC to copy the updated BIOS and a few other files).

The jumpers are set right. I used the table at http://gboeger.de/Computer/Asus_PVI486SP3/pvisp3-cpu.html to get the settings. I only booted as far as the BIOS / POST screen earlier, but it was correctly detected. I need to find a DX-50 so I can test for undocumented clock speeds. I'm hoping to find …

It's set to 3.45V. I only have settings for 3.45 and 3.6 on this board.

Finally got the board to boot. It originally had an unknown upgrade processor (QFP on adapter with glued on heatsink and identifying labels removed by previous owner). The jumpers were not set for any known 486 clone. I replaced it with a working 486DX4-100 &EW. It still wouldn't boot. Interesting …

It has POSTed, so should be alright. I will install Win 95 tomorrow and check the revision. Might run SuperPi before I ship it back 😀

I believe that all Transmeta CPUs were BGA. Certainly never come across one that wasn't.

Need 1Mb cache sram chip part numbers for PVI-486SP3

I want to upgrade my PVI-486SP3 to 512 KB cache, but don't know any part numbers to search for. Does anyone have any part numbers for 32-pin skinny DIP 1Mbit (128K x 8-bit) sram chips @ 15ns?

Re: What retro activity did you get up to today?
Posted on 2018-04-30, 01:05
I built a 486 system for testing CPUs (I have a thread I will update when I test the Cx 5x86-133 I am testing for a friend). No idea whether it works, as one of my spare monitors is dead, and the other needs a special power supply, which I can't find. Going to have to hook it up to a modern monitor …
