You should be aware that the Leading Edge Model D is a 4.77mhz design which means that it is as slow as an IBM PC or XT. Compared to anything running at 8mhz (like an AT&T, EPSON, numerable clones) a 4.77mhz machine is a DOG! It is the oldest possible technology (like buying single sided floppy drives). I would strongly recommend getting something with an 8086 (8mhz) or 8088-2 (4.77 - 8mhz switchable) microprocessor. The 808x technology is already old enough, don't saddle yourself with a dog of a microprocessor. Russ Sharples homxb!gritz

If you are using the computer for your personal use you will not notice the difference between 4.77 and 8mhz 95% of the time. As for single- sided drives, I still get over 500K on my AppleII single sided drive and only 360K on my double sided IBM clone. Just because a technology is old doesn't mean it is bad. Sometimes it means it is more reliable. If cost is more improtant than speed, get a Model D. It's a good machine for the price.

Over 500k on a single sided disk would require the kind of media density used on the new 1.2 meg IBM disks. I don't mean to knock the Apple II, which was a great machine in its day, but 143k drives that support neither DMA nor interrupts are ancient compared to the 360k units in the PC. -- Ben Broder {ihnp4,decvax} !hjuxa!catnip!ben {houxm,topaz}/

Epson ? The AT&T PC-6300 uses an 8 MHz 8086 uP. The Compaq Deskpro a 7.14 MHz 8086 uP. I do not know what the Epson's uP is. An 8086 running at 4.77 MHz (a Compaq Deskpro in slow mode) is 1.6 times the speed of an 8088 at 4.77 MHz (an IBM PC-XT). And even faster when compared at an 8 MHz clock rate (8 MHz 8086 vs. 8 MHz 8088). I also read an article in this group where someone wanted to upgrade an AT&T PC-6300 with an accelerator card. Why? Most cards available have only 8 MHz or 10 MHz 8086's, with some using 80826's at 8 MHz. The gains made with the add-on cards are easily swampped by the software over- head required to keep the I/O happy. A 4.77 MHz 8088 PC I might see, but.... KNOW WHAT MACHINE YOU HAVE BEFORE BUYING ANYTHING ! The guy with the 1.2 Meg floppy he's planning to put into a PC with standard floppy controller... such a deal. The misinformation to be had in this group is terrible. I wish only the known facts could be posted, with all the drivel left out. net.micro.etc would then be of real use. Flame OFF.... OFF I said.... damn thing anyway....
