Pentium with SCSI hdds.

[Dubliner]

I have a Chinese JCC FDC set to 360k and 1.2m for Physical FDDs. With no emulated FDD in picoMEM, I can access both physical FDDs. With an emulated FDD I can access the 1.2 physical disk as B:

Xtide at D000 and picoMEM at E000. I want to see if I can move picomem to a lower address and xtide as well. so as I can use EMS. DTK PC/XT Clone.

My next project is to get the Pentium with SCSI HDDs working. I think it has OS/2 Warp on it. And a CD-ROM as well.

I just built a Pentium using a zuluscsi and SCSI CDROM. No IDE in the system. Its been a fun project.

 

[Dubliner]

zuluscsi?

 

[krebizfan]

Zuluscsi lets one place disk images on a SD card and use those as multiple emulated SCSI devices. Much cheaper than trying to find working SCSI drives.

 

[Dubliner]

As far as I can remember the scsi drives were working. So hopefully there won't be much to do with them.

 

[hunterjwizzard]

If you've still got working drives it can be fun. Part of why I went with the Zulu was because I didnt have the drive enclosure for 3.5" drives, Hence everything has to go into the 5.25 bays.

I've got about about a half a dozen pcs in various states. I'm working on a PC/XT then either the pentium or a PS/1

haven't we all?

and an load of empty cases.

and an load of empty cases.

Now of that I am jealous Admittedly I do have a fair number of empties, except they are empty because I hate them and don't want to build PCs inside.

 

[Dubliner]

They are all IBM cases in that beautiful beige that the suits liked. God for bid that games would be played on them. But that goes back to Alan Turing and Enigma during the War.

 

[Dubliner]

I have boxes full of cables and power leads "I might need that". I also have a lot of MFM HDDs and adapters but don't know which goes with which.

 

[Dubliner]

I'll be taking a break from computers and going back to my model trains.

 

[hunterjwizzard]

back to my model trains.

I'm trying to decide which hobby takes up less space.

 

[Unknown_K]

I think SCSI HDs made more sense for 286-486 systems that had BIOS or HD controllers with size limits that SCSI got around.

 

[hunterjwizzard]

Fun fact: we actually still use parts of the SCSI stack today in the HPC world. I get a kick out of reminding my coworkers the first S stands for Small.

 

[GiGaBiTe]

Use the whole acronym or it doesn't make sense. "Small Computer System Interface".

It was coined in a time when computers were shrinking in size from taking up entire rooms to something that would sit on a desk at home. It has nothing to do with the physical size of the SCSI device.

The joke here is it was coined at this time yet its lasting legacy lives on in the largest computers in the world while having died out entirely in the desktop world.
