That size was in "my" first 386 SX too. I remember 965 / 5 / 17. One day I had a backup of it and typed the forbidden "format c:" command. Later I walked from 2 MB via 3 MB to 5 MB. Aztec SBpro and Mitsumi CDROM (2x with DMA support) followed later. Man, those CDROMs were huge compared to that tiny …

I'm either not sure whether it is worth it. I mean, on that Aztec it is a SCSI controller without any DMA or BIOS support... You'd better go with an 1542 that supports disks up to or greater than 8 GB. Hah, the only thing that SCSI will be powering is an 8X CDROM in my NEW NEC 386! The hard drive …

Update - I didn't really want to destroy that Future Domain SCSI card, so instead I managed to find a CT 1770 with SCSI and the requisite Adaptec controller is in place. I'll get around to powering my CDROM off this eventually... The Aztec/PB knockoff is happily powering a 2C CR 562B in a 286 just …

For the RCA connector, does pin 1, 5, and 6 go to the centre pin of each respective RCA connector (there's three), and the outside of the RCA connector (all three) go to pin 2 (GND)? Or is the polarity reversed for the RCA? They go to the center pin (I measured it on my S-Video-cable). Outside is …

Hello all, I have recently purchased an 1802 monitor, thus completing my C64. I have the 262 U shaped connector for video. I am able to find diagrams of the pinout, but I can't find any information other than the old 5 pin diagrams on how to make a cable. I want to make a cable for Chroma, Luma, …

Greetings. Can you please share ROMs contents of this board? Mine is basically the same (minus half 44256 slots), but with a strange BIOS (same sticker, but with v1.07 written by hand). Both halves that should be even/odd are almost identical, and I think that's why my board appears to be dead (no …

There might be a DIP switch or jumper block that got set to CGA 80 mode instead of TGA mode and it's either in the back of the computer or inside on the motherboard.

You know there are three turbo speeds on it, right? The turbo LED only lights up at the highest of the three. LED is software controlled more than hardware 😉 I had the same results with the benchmarks - are you using Sysinfo 4? I had that on the hard disk previously.

Quick update - the Pioneer unit was a dud. I took out a 4x SCSI CDROM from a working machine and it does work in both systems. Pioneer's laser didn't even turn on when attempting to read discs. I poked around in it a little more, and I made it worse - now the drive won't even spin up. Not surprised …

As the title says. I'd quite like to expand my Compaq collection with an old style 486. I have read mention online of a 50MHz version, but I can find no real trace of it aside from that mention.
