But there is no IDE interface in my Tower AT or at least I don't see any IDE connector. So, I need an IDE interface to ISA slot? You are right. These although being 286s had an MFM hard disk (models 220/240/260 with a 20/40/60MB HDD. Model 260 also had a 12MHz CPU instead of 10). Some XT-IDE …

I was also searching for a way to measure ISA bus speed some time ago, I'd definitely get one of these! Nice niche little card

Apart from the gw-basic specifics or the code logic (to which I haven't really dived into) there are also classic minor improvements you can do to your code. Again, after you've made sure that the main logic or drawing process can't be greatly improved, these on their own won't make the code …

You can't even use .iso if your game-CD contains audio tracks, like WarCraft II, Dungeon Keeper, Fury³ and many more... Really?

The link was mostly as a possible explanation for the "massive slow down" compared to the QB. Code optimization is something else of course.

http://oldcomputer.info/pc/euroPC2/index.htm 19V might look weird but it's confirmed working, voltages are regulated inside. What I don't know/remember is if this pinout is from the plug or the socket side, you can check for example the ground on the Schneider side and figure it out easily.

Have a look here https://bhtooefr.org/blog/2017/12/19/benchmar … crosoft-basics/ It appears that Quick Basic 4.5 is taking advantage of the FPU and can be times faster than GW when there is one available. Could it be that?

Exactly as megatron-uk said, you can fdisk/format/sys from a windows 98se boot disk. After that if you don't trust random downloads you can quickly do a basic install of win98 on some VM or a temporary one on real hardware and get the dos files that are located in \command \tools\oldmsdos and copy …

It does use the Sony interface. You didn't mention anything about it so make sure you load the correct drivers for it.

It's a proprietary 32bit PCI 2.2, the extra part is the "LAN Connect Interface" (LCI). Obviously used for network cards, although any PCI card should work in that slot.

fosterwj03 is right, you remove jumper T to enable UDMA which is disabled by default. Also according to some review found in an old magazine on google books about a similar drive, don't bother about the other two Filename Capture.PNG File size 828.4 KiB Views 89 views

Yes it's slow for games up to 1993. Without cache I'd bet it can't even run Golden Axe fluently, which is a 1990 game.

It's just so strange that Cachechk doesn't identify that there is an L1 cache at all. If I have understood correctly how cachechk works, it derives the cache size and cache levels from the speed it calculates in different ranges. When your cache performs similarly up to 256kb it won't have a way to …

There is a difference between auto-detect recognizing the full capacity of the card, and being able to use it. Also it's common for late 386s. I'm pretty certain that you just have the 504MB limit.
