Finally got the MSI BX Master again, had this back in 2000 running the celeron 633@950 and the Abit BH-6, both nice bx motherboards. MSI is in bad need for new caps, most seem bulged. What's the difference between a BH6 and a BX6R2? It looks like 1 RAM slot? I remember BX had extra one DIMM and …

Looking into my test notes, Adaptec AHA-1542CF with SD2SCSI (v6) device can transfer about 1636 kB/s on 8 MHz ISA and 1909 kB/s on overclocked 14 MHz ISA. For comparison VLB/PCI Adaptec 2842/2940 can do about 8000 kB/S (likely narrow SCSI-2 limit).

I believe the ARK RAMDAC is a clone (rebranded copy) of AT&T 21C498 part.

Sadly most DOS VGA games don’t benefit from 32bit bus at all (16 bit framebuffer writes). So in DOS EISA cards are just as slow as ISA. They are just a hair faster in GUI when using 32bit drivers. When it comes to graphics. VESA is much faster than anything on EISA . Even 16bit chips like Cirrus …

Indeed. Most controllers are just adaptors. However, there are still some are a bit smarter (a BIOS extension to handle geometry translation). And even some that are actually HBAs, like cached controllers, like this one: https://dependency-injection.com/wp-content/uploads/2022/07/DSC_1309-scaled. …

2 ELSA Winner cards: Winner 1000 XHR (hybrid EISA/ISA) which I had owned before, traded it and now finally replaced it again. And Winner 1000PRO Video VLB, which is somewhat less special, but still a very nice and fast VLB card. https://dependency-injection.com/wp-content/uploads/2022/07/DSC_1900- …

An unusual VL-Bus card with NCR77C22E+ from 1992 https://dependency-injection.com/wp-content/uploads/2022/06/DSC_1778-2048x1152.jpeg I've only seen this one on a ISA card before. Awesome card right there! The ISA 77C22E non-plus is quite fast, matching the Tseng ET4000AX. I'd be curious to see how …

Got this very late Socket 3 486 motherboard with pipelined-burst L2 cache. I've always wanted to know if the cache can help it to beat more conventional 486 PCI boards with UMC, SiS and ALi chipsets.

That Trident 9680 ISA is cool. I also wonder how does it perform. CL-GD cards are known to be fast in passive DOS mode with no accel. I wonder if the bridge chip on the trident could slow things down slightly (but I am sure it would still excell in GUI due to better acceleration architecture).

I think another benefit of not buying anything from russian sellers at this point, even from those who don't support this horrific regime, is to give them enough time to work out how to dispose their failed dictator. But politics aside, I suspect this dilemma will be over soon, at least from buyers …

This weekend, I was about to purchase a CBM 1541 disk drive for my Commodore 128 I acquired last week, but having seen the news about "peacemaking" operation in Ukraine, I am re-routing my retro purchase budget to war refugee charities. Could't be happier about my choice.

Not a typical thing I normally buy, but I've always wanted one of those. As a boy I had a C64 and this was the next best thing I could imagine but never had.
