A Dentist friend of mine is interested in purchasing a system to run some "IBM-Compatable" Dentist Application Software on. He spotted a local special on the Tandy Model 2000 at his local Radio Shack. I don't have all of the details, but I was informed by him that it runs MS-DOS, has 256K of RAM, and the standard interfaces for a printer and RS-232 connector. I think he mentioned he could get a 20 Meg hard disk. I can help him evaluate what he is getting for his money in terms of what parts of the system are included and are not included in the package (as soon as I find it all out!). What I need to know is just how "IBM-Compatable" is this box? I am not at all familiar with any of the Tandy products. Help anyone?????? George W.

The Tandy 2000 is NOT an IBM-compatible like the 1000 series. but instead, it will only run MS-DOS stuff that makes standard calls to MS-DOS. My roommate have tried it already and he has standard MS-DOS stuff for his Zenith/Heath Z-100. If in doubt, try it on the 2000 first, I'm sure the store will glad to let you play around with it since I'm almost positive it's now discontinued. It's a fairly good buy if you want non-IBM compat. The speed is quite impressive 80% faster than std. 4MHz IBM-PC William Chao wchao@topaz.rutgers.edu

Knowing what I do about the Tandy 2000 (not all that much I assure you), I think that if all he is going to run is that dental package he had better test it out at the store first. I know that, while it is MSDOS compatible, it is known NOT to be even close to fully IBM compatible, though many popular packages have been ported to it. It does have a nicer screen and resolution, and I like the keyboard. Running the 80186 makes it fairly fast but is also the source of the incompatibilities. Also, in regards to exp[ansion, I do not think the 2000 takes standard IBM compatible expansion cards. -eric- The opinions expressed herein are probably mine and in all likelihood will not be even remotely related to the opinions held by the YMCA on abortion.

Glad you asked. A year ago Tandy was having a real garage-sale of items including 2000s. I asked the salesman how IBM-patible the beast was. He said "About 5%". I replied "You mean about five pct of IBM stuff won't run on it?" He corrected "No, 5% WILL run, 95% WON'T!" I asked "what did Tandy make it for then?" He said "CAD-CAM and other graphics applications." For which, BTW, it is a hell of a nice box. But, unless you can get all the programs you need from Tandy, don't buy a 2000 and expect to use generic software. A shame, but give Tandy credit for ONE knowledgeable and honest salesman. PS: This is my only knowledge. Owners of 2000s know better and may have more (or even less?) optimistic replies. Please excuse me if this salesman was all wet. -- Mike J Knudsen ...ihnp4!ihwpt!knudsen Bell Labs(AT&T) Delphi: RAGTIMER CIS: <memory failure, too many digits> " ~E(x):[is_lunch(x) && cost(x)==0] "

If memory serves correctly, the 2000 was introduced at about the same time as the IBM-PC. It has a better chip (80186), better graphics, and higher capacity disks. Tandy introduced the machine as it's entry into the 16-bit/MS-DOS market. Tandy has been in the home computer business for longer than IBM -- but it doesn't have IBM's ability to set standards. There is a utility to convert PC disks to 2000 disks -- but programs which bypass DOS and address hardware (and perhaps even BIOS) will not run. Certain types of programs (e.g. communications packages) do this -- others do not. I think 5% is a bit low as an estimate. With Tandy's introduction of the 3000 (which is highly IBM- compatible) I expect that the low prices for the 2000 are closeouts. [I've heard reports that the 2000 is a fine machine. Don't eliminate it if its main use is to run certain specific software -- but test it first] J. Wavrik

Hi, About the 2000 and IBM compatibility. Most of the software available will not work as expected on the 2000. The main reason is not the 80186, but lies mainly in the kernal map, and BIOS implementation, not to mention the key scan differences and video interface differences. Some software, well written - a real hard thing to find - will work if all of the correct switches are set. Such as Norton 3.1, if invoked with the switch that tells the program to use MS-DOS calls for everything it does. If these switches are not available then chances are the software will not work, or may work for a while then crash (due to some obscure call). Some of these programs will give the appearance of working 100%, but enter a slight anomoly (e.g., disk full, mem full), and a crash is guaranteed. Another example of the difference subtleties is Turbo Pascal. Version 2.00 will work on the 2000 okay (except graphics and a few other IBM specific functions), but Version 3.00 will not. I even tried various installations and screen drivers. It looks like it wants to work, but just can't pull it off (everything seems to work, but the screen is blank). Some other differences are the disk formats. You need a special program to make IBM compatible disks. The Tandy defaults to 720K (96tpi DD). You must double step the drive to make the diskette look like a 48tpi. Program developement seems to work on the 2000 (i.e., more standard MS-DOS compilers and assemblers seem to work without a hitch). I have done some programming on my friends 2000 with a 'C' compiler and MASM 4.0. Overall the 2000 is a fair machine, IF you know it is not IBM compatible, and don't expect it to do IBM things. But despite what Radio Shack says, the 80186 is only a 5 to 10 % improvement over the stock 8086, not the 20 to 30 % that the 80286 is over the 8086. Compared to the IBM PC (8088), the 2000 is about 2.5 times the speed overall. This is due the the faster microcode, the 16 bit data path, and the 8 vs 4.77 megahertz clock. The 2000 is on par with my Compaq Deskpro with a V-30 in lieu of the 8086 normally installed (as it turns out the V-30 is more an 80186 inside than an 8086, thus the speed improvements). Oh well, if the Doc can play with the software and machine together for a bit before buying, he'd be in a far better position to know than anything you could say to him. -- Tim Margeson (206)253-5240 PO Box 3500 d/s C1-937 @@ 'Who said that?'
