Wish I had found this video sooner, as I'm trying to get a CD rom drive going on my recently acquired Presario 433!
From all my reading, and as Clint said, parallel port is pretty slow. I think the solutions would be as follows - Get an ISA I/O card that has an EPP port for faster reading and data transfer - Or use an external SCSI CD-ROM drive. I Know Clint mentions the computer doesn't support EPP, but I'm not sure if he's simply referring to the printer port on the PC itself, you could always add another ISA I/O card to get an EPP parallel port.
My 433 came upgraded with a 66mhz 486 (Dx2 I believe) 20MB of ram (which is the most the mobo can handle) a vibra soundblaster, and a ISA to scsi card. Only problem I'm going to hit is that the SCSI card I have doesn't support DMA so I have to see how bad its going to bog down the processor in PIO mode to see if it is feasible.
Love the videos Clint, and I agree with your sentiment, for whatever reason these compaqs are just so lovable, I couldn't be happier with mine!

On my last PC case upgrade, i decided to move to a small form factor case that lacked the 5. 25 bay for a disk drive due to at the time thinking that i hardly used it. A few months later i decided that i did still want to use the drive occasionally since it was a blu-ray write drive that i occasionally used for watching blu-rays but wanted to keep the new case but wanted something cleaner than a Sata to usb adapter and a bare drive. I also didn't want to spend another $80 on an external blu ray drive so i decided to get a disc drive enclosure similar to these but for sata and man it has gotten difficult to find enclosures for disc drives. The one i finally found that seemed to have good reviews cost $50 but i guess that was better than spending $80.

When you flicked the computer off, I was like, -Ack! He didn't shutdown first! - Then, I remembered that there was no fancy shutdown process for DOS. I haven't used a true DOS machine since the late 1990s so I forgot. That was 19 years ago for me back when I was in high school. All I had at that time was a TRaSh80, CoCo2. My first modern computer I got was in late 2000. It was an eMachines with Windows Me. I still have that computer. I switched to Windows 2000 Professional when I finally realised that Me was crap and there was something far better. Computers I got after that I had over written the Windows 7/8 with Ubuntu. I don't care for Windows especially when the free software with Ubuntu does most of what I need.

The first home computer we had was an Compaq Presario, a newer type than this, with speakers too, they were under the corners of the screen, and Windows 3. 11.
Too bad it has been thrown away, it was super expensive when new too. I miss using DOS and trying to get games working with too little RAM and Hard Drive space, I played DOOM, Hexen and WarCraft 2 into the 2000-s on that one. A time when you finally got the game running, you actually deserved to play it, and that was an achivement in itself.

I remember my 1st CD-ROM drive, it came bundled with a sound card - necessary because it plugged into the sound card to transfer data - the motherboard didn't support it! It was single speed, a basic CD-ROM is 650MB and my HDD was 250MB at the time! I ripped a few tracks, rip 1 track, encode it to MP3 and then rip another track! It took hours to encode 1 tune on a 486sx-25mhz IIRC, crappy encoder Blade-enc, was a bit flawed compared to LAME.

The one thing that would be awesome is have someone make a board that has both power and data (IDE) connections on the rear of the machine either using the add-on card slots or blank spots to connect from the motherboard and PSU to a CD-ROM drive externally instead of the parallel port since some of the BIOSes only have bidirectional or output only on the parallel port, no ECP or EPP.

I used almost that exact model of backpack drive when I was in high school. I went to a computer camp during the summer, and we had one of those that we'd take around to all of the computers to use in turn. Mostly to burn CDs of PowerPoint choose your own adventures we made (this was right after hyperlink support was included in PowerPoint haha)

I was restoring a Sega Genesis and opened it up to find tons of rust on the inner RF shielding, didn't even matter that it was there really but I sanded it all down and sprayed it with a nice even coat of rustoleum primer to stop it from rusting further. Not sure why but it's super satisfying to know it won't degrade any more I guess.

I had a similar LPT cd rom for my Compaq Presario 433. It worked good, but was slow when it came to movies. Cutscenes in Command & Conquer were very choppy. I solved it by simply skipping the external case. Instead I used a looong IDE-cable and a Y-power cable, and placed the internal cd-rom outside of the computer.

Can't rem brand, quantum, la cie, ? Had a adaptec 1848 parallel to scsi chip inside case.
Zip parallel drives had an adaptec chip same as 1848 chip.
I think win98 came with a driver. Long boot time to check all ports for PnP devices.
A non Zip adaptec parallel to scsi adapter can select >1 device.
