Hey oldcomputerfreak (or others who know old comps) I'm callin ya out!

[markjs]

I just got a laptop to play with (free) and it's an ancient Zenith Quattro Pro. What is it? 386? 286? Where can I find info on it? It wont do anything but say "Bad or missing Command Interpreter" and has no other markings to speak of but serial numbers, model ZWL-183-93, and FCC ID:EDI9YA-557CPP15. Any clue on what it is and what to do? boot disk doesn't do anything (win 95 though I didn't expect it to), and I cannot figure how to enter setup. Thanks

If it's a *really* old laptop, you might try running Dos and Windows 3.0 or 3.1.

The error message sounds like a DOS one, ie it can'd find command.com.

Cheers, R.D.

[butchsor]

Yeah, it's the missing DOS.

CMOS set-up, try:
ALT+Delete, F4 or try all function keys http://discussions.hardwarecentral.com/smile.gif

I know only Quattro Pro--the best worksheet apps. made by Borland that knocked the infamous Lotus 123 http://discussions.hardwarecentral.com/smile.gif

Butchsor is right, no Dos. You need a dos bootable floppy. Once you boot from floppy check that it can see the c: drive. If it can try "sys c:", if it can't then use "fdisk" to recreate a primary partition followed by "format /s /u"

[JollyRoger]

You Command.com is defunct, follow uart's lead for replacing it, but be carefull of your DOS Version. REALLY old machines (talking 286) might be running DOS 4 or earlier, which is bad. it will run DOS 6, so find a copy and try it, it's worth it for the extra base mem from Himem

[david21136]

what do you think is better to load on a ZWL-184-97 dos or win 3.1 or win 95

[ThreeOnTheTree]

Hard to say without knowing the specs, but it needs to have either a pretty fast 486 or a Pentium CPU to run Win95.

[Justintime]

One site i see lists memory below a meg, so DOS is most likely all you can manage.

Floppy Disk Drive- 1.44MB "3.5 disk"
Hercules LCD
16MB Hardrive
640k ram

Win95 is a loooooooong time away son.

[Hoyle]

I'm guessing it's probably a 286 4 or 386 8 Mhz chip.

640k RAM! I think that's one step up from a PC Junior. I don't think Windows 3.1 will operate with less than 2MB - and performance is terrible even with 3MB.

But you would want Himem. Without it DOS only uses 64K (16-bit), I think.

Dos could address 16 64kBytes segments (1mB of address space). You needed himem on a 286 and above if you wanted to use the wrap around kludge, giving you an extra 64kBytes of address space, that could be used to store resident programs such as drivers or even command.com. Himem was also required on 808x and above if you wanted to access ems memory using and ems driver that would let you access several megs of ram via a windows usually at segment D000.

[david21136]

its a Pentium with not event a gig on it

[ThreeOnTheTree]

Gig of what? Hard disk space? Even so, you should still be able to run Windows 95 or 98. At least then you could run some apps. Anything older than that and you're going to have a tough time finding software.

[Todd a]

Yup. It is a dinosaur:

4.77 or 8Mhz 80C88 (186 I think), optional 10 or 20MB hard drive, 720K floppy, 512-640K memory. The modem was a 1200 or 2400 baud external modem. Man this is a door stop. DOS is about all you will get running on this.

Didn't know that, thanks Gluss.

No such thing as a 186, Todd, although the 80(C)88 WOULD have been a 80(C)186, had Intel switched to the newer naming convention (80(C)286, 80(C)386, etc.) sooner. Instead, there was the original 1802, then the legendary 80(C)86 and finally the 80(C)88.

[Todd a]

Well I know that, but I thought it was the IBM PC, 286 (my oldest brother had both of these), 386, 486. I call the IBM PC a 186. I think my old TRS-80 Color Computer used a 2Mhz 80C86 or something like that. Old... reary old indeed. My first computer was a 286 SX 25Mhz with 2MB on board. This is WAY beyond this Zenith system. :D

I mean come on... this is the chip they show as the CPU:

[Hoyle]

Well, the chips were manufactured for IBM's PC and PC Jr products originaly (with Tandy the first real clone). But they were always Intel brand names (even if IBM practically drew them up).

No, the coco computer was equipped with a Motorola 6809 processor.

ZFL - 184 - 02or97 SupersPort

this is the web page that has the stuff about it on it

Not a pentium, this was before pentiums existed. Windows 3.1 would be a snail on that thing, Windows 95 is out of the question. DOS is prolly the answer.

[Todd a]

Yup you are right:

http://www.old-computers.com/museum/computer.asp?c=91

I have worked on several of Radio Shacks old one. My oldest brother had the TRS-80 Model 1, my school had the Model 3 and 4, and onther bother had the CoCo model 1. I eventually picked up the CoCo model 3 when Radio Shack started dumping them for $50. Those were the days man... casset tape drive just rocks! :D

i have the same laptop and it looks like it has a 613mb hd in this thing and it had a system that was natave to that laptop where it had lotus, word perfect, norton intagrator, professional writer and some funky net program a graphics program and one like excel
