The Colani tower indeed had separate side panels but there were other cases from Vobis as well - I used to own one back in the day and made a thread about it not long after I joined vogons 8 years ago 😅 Filename gettyimages-875825320-594x594.jpg File size 39.29 KiB Views 106 views

Yes, I've tried with "boot up floppy seek" enabled and disabled. The floppy correctly seeks at boot - seek noise and LED lighting up. But when trying to boot from a DOS floppy disk, there's one short access to the floppy and then nothing. The boot disk works correctly as verified on other machines. …

I assume that beige box is a model 80? Interested to read about yours - I got one of these as well 😀 I got curious about the Yamaha NX50 speakers a while ago as I like their design but in the end I didn't get a pair as IIRC they're not shielded...

Yes, you can upload a good picture of your board. Here's my board. To me the jumpers seem correctly set but who knows, maybe something slipped my attention :) VLI486SV2GX4.JPG Oh. I am a bit surprised, I thought you have the floppy problem with a CPU that supports L1 write back. But you have the …

Hi, so you are using a CPU (like Am5x86) in L1 WB mode, too? Which revision of this board do you have? But anyway the latest BIOS revision with the write-back fix is highly recommended for that board. I can confirm my board is rev 2.0 - I've just updated the BIOS to the latest ​one (VL/I-486SV2GX4 …

Nice! I love the look of that Fujistsu system - these black setups weren't common back in the day when beige was everywhere 👍 Nice midi rack too. Curious as to why you're looking for an M-GS64 and not an SC-880 for example?

There is a sharp kink in the adoption curve though, ~75% of 20th century PCs were sold between 1995 and 2000, the remaining ~25% was pre 1995. If 486 production had cut off sharp at release of socket 5 Pentium, then we'd probably only see as many of those as 386s, but they were selling as low end …

Any opinions? I am aware of the brand …

twisted ? don't those drives have a common cable and a separate cable? No twist required. the data cable being common, straight cable for all connectors the control cable being separate per drive. and maybe also a termination resistor to be removed. a floppy drive "needs" a twist, but an mfm/rll …

Last time I opened up my Sony 17Sf monitor I couldn't find any trim pots for adjustment. I think it needs WinDAS for this purpose, and unless I'm mistaken the 420GS is more recent than the 17Sf... so I'd wager it needs WinDAS as well

Good to know you have managed to resolve the issue.

This thread reminds me I might need to update the BIOS and see what …
