My Atari 800XL
The Atari 800XL is a member of the Atari 8-bit family of microcomputers. Even though the Atari 400 and 800 looked absolutely hideous, the whole family was very easy to learn and use. Most importantly, the entire family was backwards compatible. The original cartridges will work in the XL and XE systems just as they did in the originals. Now, about the 800XL...let me begin by explaining a little bit of history.
History of my 800XLBack in the late '90s my father came across a garage sale. It turns out, the man at this garage sale had an Atari 800XL, a Zenith monochrome monitor, a 1050 DSDD floppy disk drive, and several cases of floppies and manuals. Now days, such a thing can make mouths water. Of course back then such computers as the 800XL were just outdated trash, so the man offered to give it all away! For some reason, probably just to be nice, my dad offered him on the order of ten dollars for the whole setup. But of course, being outdated, my dad stuck the whole works in our attic for 15 years before I stumbled upon it. Okay, so what's the big deal? Well, this was the defining moment for me. The time my eyes landed on that old system was what started all of my collecting.
So, anxious to get things working, I set the system up in the house and much to my dismay, the 1050 floppy disk drive died halfway through reading Pooyan. I will write more about the drive later. Essentially what ended up happening is I threw the drive and all of the disks back in the box and started to learn Atari basic, since that was the only thing that the computer could do.
Making It UsefulNaturally, basic was...well...basic. I got bored. So my curiosity lead me to eBay where I found this nifty thing. It is an RS232 (serial) to SIO (Atari Serial I/O) disk drive emulation cable. The most common program for Atari emulation was APE (Atari Peripheral Emulator), but I found a program called AspeQt (Atari Serial Peripheral Emulator for Qt) to be much easier to obtain and use for my purpose. I discovered an index of the pirated Homesoft's Disk Images from way back when, and began to build my own virtual collection and corresponding HTML index for it. Suddenly, for only 30 dollars I had myself every game ever made for the Atari 8-bit systems.
PeripheralsAs I mentioned before, my Atari collection came with a 1050 disk drive. The thing used to work great, but one day it simply failed to do anything except get really hot. In the process of trying to fix it I managed to throw it out of alignment and damage one or more IC's. It's safe to say it's a fried mess to deal with another time! But I did end up discovering the likely cause of the original problem. Like many devices from that era, the rectifier portion of the power supply is built into the main case, and only the transformer (supplying AC) sits inside the external power supply. The rectifier circuit called for three 35 volt electrolytic capacitors rated at 4700 microfarad. At some point in the past, someone had replaced two of them with 25 volt caps, which did not completely stabilize the fluctuating current to DC, which caused the overheating symptoms on the voltage regulators and eventually the death of an important IC. Acoording to my responses on AtariAge, it could very well be the 6532 RIOT (RAM I/O Timer) that fried. But like I said before, fixing that drive is a task for another day.
Recently I picked up a 410 casette tape drive. After rolling out a pretty sizable dent in the stainless logo plate, it was a pretty good looking player. The only major problem with it now is that all of the belts are dry-rotted. It can play and fast forward without a problem though, and for now I will just flip the tape over to rewind!
To read about the Zenith monochrome monitor that I mentioned earlier, look at the article about my TI99/4A, since that is the system I use it with.
CartridgesMy Atari 800XL came with 6 cartridges.
The first cart is obvious: Space Invaders. What is a classic computer without a copy of Invaders? This cart was manufactured by Taito America in 1981, and first made in 1979. The game functions like most other Invaders games for the most part, except the speed of the game is different. The invaders scroll onto the screen slowly, appearing to come out of a large mother-ship. Then they immediately proceed to wooping some serious butt. Funny enough, I switched the game to the hardest level and performed far better than I had on the last ten runs at level one.
