I used a QLT Futura 100 - aka OMNOVION PGSiii based every summer from about 12 years old to 32 Only about 4000 of them were made in various flavors.

Re: External cache on or off? 256MB SDRAM and 430TX motherboard for DOS games.

What specific dos titles do you have in mind? They are all different. If you disable L1 & L2 cache you should end up around a 386DX40 level of performance

SASI, the name of SCSI when Shugart associates ran the show? Generally SCSI-1 and SASI are interchangeable, the controllers for either will usually drive either type of drive.
Re: CGA "optimal" palette (fantasy)
Posted on 2020-02-18, 03:05
Something that is never done on CGA but done on a variety of monochrome platforms is to flicker between the two pallets on every vertical blanking. Takes zero programming skill and minimal cpu overhead You would still get 4 colors but they would be brand new (not very good) But not the normal 16 …

Large or big mode gets you up to 1gb on many older machines. Oddly 540mb hard drives were very common, much more common than anything 500-528mb, one would hope A machine made post 1990 could use one

In the scenario that you have this much cache one would wonder the effect if you could map half of it as base ram
Re: L2 cache and 386 performance
Posted on 2020-02-01, 21:14
I used to have a very compact 386 board that had a couple kB of cache integrated into the chipset. Made the board suprisingly fast. I kind of regret selling this board because it was such an interesting oddball. I wonder if that chipset would support additional cache? If only I could remember the …

Looks like an interposer. Some early p60’s needed 5.5volts, the real early motherboard models are hard to find to verify

Re: New ATX power supply standard will be 12v only
Posted on 2020-01-28, 04:03
The question is why call this new thing ATX? A unified voltage PSU may as well have a bullet connector or worse an external supply. I’m imagining a humming $5 space heater inside the case. What’s even better is led computer lights will either grow in cost or become incandescent . Seems like a big …

Most were card games, “Japanese games” board games, hangman, “learning games”, typing games and …

IBM Blue Lightning 486slc3 is really the only viable option here. Still would need an adapter and a rare Japanese upgrade to get one.
