Greets: This weekend I had a great run of the swap meets, etc., in Wichita, Kansas and came home with about 50 different machines, tons of software, etc., etc. Anyway, there are two specific machines I would like to ask about now, I will post further questions on several others in the future. First, I picked up an Epson HX-40 laptop-sized computer. On the front it says MagicBox above the LCD screen. On the back there is a battery bay as well as a rom chip bay, and it says Epson HX-40 Model # H401A. I understand this machines runs off of program-specific rom chips. It has a chip in the slot under the trap-door, and when I boot it, it comes up to a pharmacetical company inventory, order, etc., menu. The machines runs off of 4 AA batteries or a AC adapter. It really is a cute machine, but I want to know more. In searching the web, I find 1 measly reference to this machine... yes, 1 (or two), neither of which give any info. on this machine. It is listed on a guys resume as having experience in working with it. I do find a lot of information on the well-known Epson HX-20 --- known as the 1st laptop computer. In finding pictures of that, this one looks really similar. This one has ports labeled BCP and one labeled SP on one side, and on the back is the cassette, seriel, and RS-232C, printer, and power adaptor ports. There is also a 50-pin port on the opposite side with no label. I guess what I am wondering is if any of you have some more information on this little guy? No year can be found on it, but I suspect early 1980s. Does anyone have any other 'chips' for it to insert other software into memory. Are these units rare? Please let me know any information. If you're interested in it let me know that to. Next, I am curious about a Data General One laptop computer I picked up. Specifically, I need to know what type of power supply it takes, as I can't find that information anywhere. It says it is ms-dos based, but I am wondering what dos would run on it. It has 2 3.5" disk drives (Epson drives), and I am curious as to if it had a hard drive? It has a full-screen, I would suppose monochrome? Could it display graphics, etc.? Also, when was it made? *any* information on the above two items most certainly are welcome, and would be quite appreciated. Please let me know if you are interested in getting either one of these as well. I will post some more very unique items in the next couple of days that I was lucky enough to get my grubby little hands on.... Thanks in advance, CORD COSLOR -- ___________________________________________________ | Cord G. Coslor : archive(a)navix.net |\ | Deanna S.

Anyone want a Cray

by maxeskin＠hotmail.com

How much sense does that make? Isn't it a bit like saying "You can pay 100,000 for it, or you can pay 10, either is fine with us"? If it doesn't weigh too much, ship it to the US, I'm sure there are more customers here (I doubt I'll get much use from it, unless it runs term and MS Word ;) >How often do these come up for sale?

Stupid BIOS tricks

Stupid BIOS tricks

by peacock＠simconv.com

> I just downloaded the assembly source to a generic XT bios. It compiles, > but I can't apparently run it from a command line, or boot off a floppy > disk that has the thing rawritten on it. A BIOS is linked to run at a preset address, usually F000 (64K Z80) or F000:0000 (last 64KB segment on an 8086 in real mode). What I have done when debugging a BIOS is to link it at a lower address (say, 8000:0000), then load it into memory at that address with a debugger, set the CS segment register to 8FFF (a true reset puts it at FFFF), then jump to 8FFF:0000 (simulating a reset to FFFF:0000). Since this is an XT I assume you will be running in real mode, so address translation isn't a problem unless your machine has some kind of additional address mapping logic. Of course you can't run the debugger after that as the BIOS will trash all your vectors. Be sure to modify the BIOS code to stop the memory sizing test below segment 8000 or you will memory test right over your BIOS image. Hope this helps, Jack Peacock

I got an Apple ProFile hard drive.

by rcini＠email.msn.com

I just got an Apple ProFile hard drive. It seems to work, although I don't have an interface card for it yet. But, it squeaks. You know, like a water pump on a car before it blows (that's the pump bearings, BTW). Does anyone have any check-out/maintenance tips for this drive? The hard drive is labeled "Seagate model ST-506".

Junk nite

by adavie＠mad.scientist.com

Just curious if I should really keep this rather well designed computer Its an "Olivetti M24 Personal Computer". I'd never seen an Olivetti before, which is why I saved it from the scap heap. Now is it scarce or nice enough to attempt to get running? If not, it becomes my new post box - rip out the drives and contents, sit it on top of a pole outside the house, paint the house number on the monitor screen :) Should look good! Also found, and free for a good home (cover my costs) a great condition box set of Texas Instruments Professional Computer MS-DOS manuals. I don't but thought somebody else might want them. Andrew.

Stupid BIOS tricks

by maxeskin＠hotmail.com

I just downloaded the assembly source to a generic XT bios. It compiles, but I can't apparently run it from a command line, or boot off a floppy disk that has the thing rawritten on it. Is there a way I COULD do it without getting a ROM burner? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Kaypro 4 modem

by alanr＠morgan.ucs.mun.ca

I just got my hands on a Kaypro 4 in excellent condition, complete with software and manuals. However, I cannot seem to get the internal 300 baud modem working. I have two programs here with it, one is KERMIT for the Kaypro II CP/M 2.2, and the other is Superterm Version 5. According to the addendum with the machine, the version of Superterm that I have was modified for use with the internal modem on the Kaypro 4, however I cannot seem to get the modem to do anything. Would this modem accept AT commands? and if not, what commands do I have to send to it in command mode? Any help would be appreciated. On a side note, anybody remember the Star Trek basic game? They just don't make games like that anymore. I'm sitting here with Quake, QuakeII, and a whole slew of other advanced 3D games on my pentium, but I cannot tear myself away from playng Star Trek on the Kaypro! (getting my ass kicked, can't aim the torpedo's worth a damn :)

Is there some special trick required to get RT-11 to sysgen?

by DSEAGRAV＠toad.xkl.com

I do @sysgen and it runs out of memory every time. Under RT11XM. I have 2 MW of RAM here, shouldn't that be enough? -------
