These computers became popular in Poland as home 
		computers, along with Commodore 64. They had better sound and graphics 
		than ZX Spectrum for similar price and software library size. It's successor 
		of Atari 800 computer, with memory and chip upgrades. However not all 
		programs from Atari 600/800 was compatible with XL computers due to ROM 
		modifications. 
		Finally, in 1984 Atari released 800XLf, currently hard to get Atari 800 
		with Freddie memory management chip. This chip, an analogue to FC572 
		systems CAMMU, made memory usage faster. In its lat days, Atari tried to 
		resurrect 800XL by making them cheaper. The new Atari 800XLRC (Reduced 
		Cost) used mixed array chip called Keri, but it had never left prototype 
		stage.

In its parameters, it's Atari 800XL, but in futuristic 
		Atari ST's case and without rear parallel bus. Most of 65XE units are 
		130XE models but with memory (and memory driver MMU C025953) stripped 
		down. These units usually have "Expansion" additional slot, which 
		extends cartridge bus giving possibilities of 800XL's parallel bus. 65XE 
		was the most popular "small Atari" in Poland because it was relatively 
		cheap and accessible easier than other computers. Memory of these can be 
		expanded to 128K, but MMU must be installed or... some hobbyists just 
		built their own MMU analogs using GALs, TTL logic chips or even EPROMs. 
		If you're curious, look at De Re Atari site in Links section.
		Atari 800XE was the 64kB version for eastern Europe. As some 65XEs (see 
		below) it has 130XE mainboard with expansion connector, but has no MMU 
		and no 2 RAM chips. This Atari is quite rare and was sold for time 
		smaller than one year. It was one of the last models of 8-bit Ataris 
		sold at all. If you want to find 800XE, look in Poland, Czech Republic 
		or Slovakia, they're not much known even in Germany.

In fact there were 4, not 3 versions of 8-bit Atari 
		computers in ST-style. They were:
 - 65XE with 64kB RAM - it has no expansion port.
 - 65XE with 130XE mainboard without MMU and half of RAM - it has expansion 
		port.
 - 800XE - as above but with 800XE markings.
		-  130XE - with MMU and 128kB of RAM. 
Here is an exact comparison of these computers:
65XE mainboard:
| Contents: | Starting | Image file formats | Recording media | Video pinout | Links | 
It boots directly to Atari BASIC, where you can use tape 
		with CLOAD and CSAVE commands. After pressing a button on tape recorder 
		you should press return to start tape motor. If you have a disk drive 
		connected to it, you can use it as normal media or boot the software 
		from the disk.
		But remember that many disk drives used many recording formats, which 
		means that for example disk recorded in Indus GT drive may not be 
		readable in Atari 1050 drive.
Disks:
 - ATR - standard disk image supported in many 
		emulators and SIO2PC transfer software.
 - XFD - direct byte-by-byte dump, you can convert them to ATR with XFD2ATR
		
		HERE
		- DCM - It's an Atari file format containing compressed disk image. You 
		have to unpack it to ATR with DCM2ATR (look in files)
		- SCP - Like DCM, it's Atari format used by SpartaDOS, so you need to 
		extract them using SCOPY. 
		- PRO - Copy-protected disk image used by APE program.
		- ATX - General format for storing copy-protected disks.
		You can convert between them using 
		Imagic
Tapes:
 - CAS - General cassette format
- XEX - Atari executable file. It can be placed on floppy or cassette.
After this quite boring introduction about file formats, 
		I'm going to explain complicated procedure of recording a cassette with 
		software for our Atari. The first thing we should check is Atari tape 
		recorder. Some companies modified them to make tape load faster and if 
		we have one, we won't get our tape running without special software (cartridge) 
		in Atari. So just look inside and check PCB if there aren't any 
		modifications. We need a file in CAS or XEX format. You can also try to 
		extract XEX from ATR, for example by using
		XDIR, but 
		test (in emulator) these before recording - maybe it must read something 
		from floppy?
		If you have XEX, you must convert it to CAS by
		XEX2CAS. 
		Now, convert it to WAV usint CAS2WAV from the same source as XEX2CAS.
		Now we can do two things:
 - Record this file using an ordinary tape recorder and hope that Atari 
		recorder will play it.
 - Load  it directly to Atari using Atari recorder and car audio 
		cassette adapter (a dummy cassette with jack cable and head instead of 
		tape) and re-record it to a normal cassette. This won't work in all 
		cases, some cassettes have complex loaders.
Turbo cassette recorder?
		If you know which turbo system is it, you can try to use
		TURGEN program 
		to generate CAS or WAV (as well as play live) file suitable for the 
		system. Currently (2011) TURGEN supports Czech and Polish standards.
 
Getting disk images
		You can simulate disk drive by using
		SIO2PC cable 
		and software. SIO2PC is a standard cable in PC-Atari transfer, so you 
		can also use commercial (shareware) APE program. I think there are some 
		disk copiers, which may copy the disk from virtual (PC) one to real 
		floppy disk drive.
