Extending a request for ATronics 2015PL cross-check, if somebody has controller based on this chip and is willing to spend some time on it. The late DOS driver (version 3.27 06/08/95) offers control parameters, but seem to be problematic in general. Performance is really bad. ~0.35Mb/s according to …

Ends with G. dm-, i am sure the benefit will be minimal. This is more for having a few minutes of casual retro-fun than achieving any specific objectives.

It is exactly the same as the Rev E and F in TRW pictures. I think that will be ts07 ?

Revision E https://theretroweb.com/motherboards/s/ford-lian-agp-ali My level of interest in SS7 stuff is low, but since this came to me for free decided to give it a spin. For the purpose converted a K6-2+ 550ACZ to K6-3+. Also, swapped 2-3 bulged capacitors. Everything works as expected. Now the …

Most VGA cards will work fine if inserted into 8-bit isa slots. Including on XT clones - either 8088 or 8086. The only cards that may cause problems are very late models based on Cirrus Logic GD-5434.

Are there are commercial or custom built 132-pin PQFP-to-PGA adapters (386DX CPUs) ? Searched online, nothing came up. Have some blurry ideas, but nothing that can be assembled from spare components coming from standard consumer retro-electronics. Want to check i am not missing options before go on …

Performance on system-level, PC-oriented benchmarks is 5–15% better than a standard 386SX at the same clock rate; on some benchmarks, such as Dhrystone, it is as much as 35–40% faster I assume it's mostly still bottlenecked by its 16 bit bus? The article talks about SX derivatives, so 16-bit bus is …

The different thermal "profile" of the two 386 CPUS at 3.3 and 5 volts is interesting indeed. So, maybe they are different after all and simply deliver similar performance. Hah, using the same board. Okay. That makes sense. Switching to CF cards makes it much easier. Also, they tend to be more …

If ALi M1386SX has the same perf as VM386SX+, this is a strong indication they are the same on the inside. Online searches doesn't return anything meaningful enough to support, or disprove it. Noted about 386SLC. About 286 - very nice. Good video (bombastic name ! ;) ). What motherboard ? If you can …

This article is from year 1993, but the PGA132 DLC/SXL2 models came to market in 1994. Apparently both Cyrix and Texas Instruments saw market opportunity for 386DX upgrades and went for it. Early 486 components are in my blind spot, so cannot comment on your questions about TI/Cyrix 486 designs. But …

According to this legitimately looking document, the VM386SX+ is its own design that is 10-40 % faster than baseline Intel 386SX. Suddenly the 386SX field is more interesting.
