I've always loved the concept of caching. I've always thought of it as an optimization, and all optimizations, especially when they're simple and effective, are welcome.We don't need moaaar powaaaar. We need moooaar caching!#Caching #Optimizing #IT #SysAdmin

@stefano That's why I always install one of these babies in my machines!!!! :D

@ltning @stefano Oh, LTNS, Tekram!I had DC-390F before (unfortunately, this model doesn't have cache mems).And (not 100% sure as I've not recorded) DC-680 for IDE.

@TomAoki @stefano I use them to attach drives >504MB to my retroboxen. I know XTIDE is a thing, but there's a charm to these old clunkers. :D

that’s actually why i just go crazy with old SCSI disks if i don’t want to bother with two small IDE disks (and forgoing the CD)

@wec SCSI wipes the floor with IDE any day of the week. But since I absolutely cannot stand the whine of real HDDs (I know, I'm an impostor) I usually go with CF cards - or the occasional ZuluSCSI or whatever for the more beefy builds. :)

get you an old SCSI RAID controller and put a few ZuluSCSIs in RAID, it'll flyyyy!!! I've hit old cardslot bus speed limits a few times with four ZuluSCSIs that a friend has now (he needed them more than I could ever, I prefer real disks as I love the dulcet tone of the hardware... but they'll one day die)

@wec Got an OS/2 Warp3 machine running Novell NetWare server: One EISA SCSI controller (plain Adaptec right now; the batteries on my Compaq RAID controller needed to be snipped off) with a ZuluSCSI; one VLB IDE controller with a (fast) CF. It's a 4:1 ratio in actual transfer speeds.Since the machine is just a 486DX50 there's no big point in going full UW SCSI on that thing, but I'm pretty sure I could go well beyond straight Fast SCSI.

is that NetWare for OS/2 or did the machine formerly run OS/2? I've played with NetWare for OS/2 (the weird virtual machine thing) and was blown away that it was ever written)

@wec That's NetWare for OS/2. Paravirtualization anno early-90s. It is a piece of work, indeed. It runs the file server for my BBS and various other old machines.Fun facts you already know, but that I can wake up at night thinking about: Disk devices are handed to NetWare wholesale, and has to be managed there (partitioning and all) - but the actual I/O is handled by OS/2. This as opposed to network cards, which have drivers loaded directly in NetWare. There's a special "loopback" driver for both that allows OS/2 and NetWare on the same machine to talk to each other without needing a (pair of) physical cable(s).

oh yeah, that's the one! good theme going on too! gotta love the loadsnake down there... imagine if that thing supported multiprocessor systems!multiprocessor OS/2 is a real piece of work... somehow I got 2.11 SMP to work with 4 processors lolBTW there's a screenshotter on a lot of the OS/2 Developer Connection CDs!!!

@wec Hah yeah, that would be fun. I keep looking for dual 386 or 486 systems but never found any. Got plenty of pentiums but that's hardly a challenge..I hear 2.11 supports 64 CPUs but IBM was only ever able to test with 32...I know - there are some good screenshot tools. I just picked this one from my library and cut out the surrounding - the full pic is the whole rack. Something like this. Should take some new pics, there's a lot of new Lego installed these days. Including one of NCC-1701-D's shuttle craft.

that's a VERY good machine there!as for dual-processor 386es, your best bet is a Compaq SystemPro. shame mine is burnt out otherwise I'd video it :((

@wec That is hideously fantastic. I spent some time trying to compile #snac on OS/2 a while back, but in the end I had to give up. I hope to pick it up again one day... Someone knowing what they're doing might get it done in 20 minutes, using EMX or kLibC or whatnot. I got to the linker step..

@ltning @wec with kLibC it’s amazingly close to Unix, even mksh just works
