I just picked up an AppleII and 2 FDDs with a bunch of add-ons at a local thrift store. The only Apple I have explored is my Mac+. Anyone able to identify the cards ? A Disk II interface card...... obvious. Ram Module by Multiflex Tech Inc.....I imagine additional ram Grapple+ Printer Interface......... Serial, Parallel ?? Multiflex Tech ...Long card with kludged cable to an RCA male connector and another to a clothes-pin chip staddler labelled AP TC/14. Two labelled chips "Firmware" and "Char. Gen." (imagine this is a video card of some sort.) Modem 80 card with 2 tel. jacks........... Baud-rate ? CableTV kludge to a "SUP 'R' MOD CH.33 TV Interface Unit ?? External added-on connector 2x3 blade (like an AC outlet but with 3 pairs of smaller female recepticles in one unit) ?? It also has what I imagine is stock Ext. video (single RCA) and cassette (2 mini-pin i/o ) Any help appreciated. ciao larry lwalkerN0spaM(a)interlog.com

Thinking about selling my TRS 80 Model 100

by transit＠primenet.com

Last fall, I bought a Model 100 which was fine, except the LCD doesn't work. I thought I could fix it, but find I really have no time to troubleshoot it . .. I'm willing to resell it to anyone on this list for $10 + shipping, send me e-mail if you're interested. ------------------------------------------------------------------------------- Charles P.

PDP-11/34 & DG Nova-3

Inspect it visually to make sure there are no obvious uprooted components, cooked tracks, etc. Connect dummy loads between the important supply rails and ground (I think they are +5V +15V and -15V in a PDP - Can someone confirm this? Do you need a load on the 20V rail as well?) and switch on. Measure the voltages across the dummy loads. Generally the 15V rails don't need to be loaded very heavily - a resistor of 100 ohms rated at a few watts ought to do it. You ought to try and draw several amps from the 5V rail - a 6V car headlamp bulb is ideal. Light bulbs make good dummy loads in any case because you can see if there is any current there... Beyond that, there are plenty of PDP hackers on this list who can take up the story at this point... Philip. PS I too will admit to not doing this nearly often enough...

TRS80 Model 4P problem

by KFergason＠aol.com

I have a slightly wierd problem. Not sure if it is hardware or software. Ok, I turn the 4p on with no floppy in the drive. It says: The Floppy Disk Drive is not Ready. (in 3 languages, no less) I put in the TRSDOS 6 system disk, the system appears to boot, but the monitor looks like there is no sync. It is very fuzzy. I can type in the date, and enter a command (dir :1), and the system appears to do it. Why does actually getting booted up cause the monitor to be unusable? Trying other disks in the drive, if they are not system disks, causes other messages to appear, perfectly readable. Any ideas? Kelly

Epson HX-40 ???

by archive＠navix.net

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....

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"?

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

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.

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 :)

System/34 contd.

by maxeskin＠hotmail.com

UHOH! That means that I will have to move the thing! It's against the wall! With three 74-pound terminals on it, no less! This machine ran in 1980, when it was last used. Possibly, it has been eaten by the two- foot long rats that live in our building. To restate what I previously said, it needs a 220-v power source and I am trying to run it in an area that only has 110-v plugs. >[Previously, a load of questions...] >The CE panel is the Customer Engineer panel.

System/34 contd.

by maxeskin＠hotmail.com

For one thing, what is the CE Panel? The thing is in a corner, with the end that has the floppy drive on it visible, as well as the side that has a small power switch on it. I went down to Radio Shack, they only had 220-110 transformers that could handle up to 40 Watts. I have a hint this might not be enoug ;) Also, they had 110-220 transformers. Could I just wire one of those backwards and get the same result? Wouldn't it be easier to just wire two 110 volt plugs together like I was told I could try if I like "but I would far better notter"? IS this indeed like trying to move heat from a cold to a hot object? How many question marks can the listsevrer handle before crashing? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

A big string of DASDs adds up very fast, especially the power > sucking IBM disks (why is that? Really big motors)? I don't know where the figure of 250kW came from. I cannot find it anywhere. I have found some figures, though, for indifidual 3090 processor units _only_, dated 1986 and 1987. While I agree with you in principle, William, you'll be surprised at some of these. Figures are electricity consumption in kVA - an upper bound on kW, but not a useful indicator - and heat output in Btu/h which I have converted to kW, which should give a lower bound on electrical power requirements. 3090 Model kVA kW Heat 150 (1986) 32 23.2 kW 400 (top of range in 1986) 83.6 61.8 kW 400 with vector coprocessor 97.8 70.6 kW 120E (1987) 29.7 21.4 kW 150E (1987, replaces 150) 30.4 22.1 kW 400E (1987, replaces 400) 79.9 59.6 kW 600E (top of range in 1987) 95.6 71.5 kW 600E with all expansion 134.6 103.6 kW Note 1986 figures were given with and without vector facility; 1987 figures were given as minimum and maximum values. These figures are not even for a minimum system - you have to add disk drives and that awful 400Hz motor generator set - which can consume up to 7kW in itself. So, as I said, a typical system based around, say, a model 200 might consume 50kW, but even that needn't cripple you financially. Philip.

Date: 7 Apr 1994 13:48:35 GMT Right after I posted about hooking a 6522 VIA up to a PC parallel port to turn the PC into a "char-banger" instead of a "bit-banger", someone posted that they had thought the 6522 had a problem with the shift register. The poster also said that Jim Butterfield had alerted him and others to it. Well, I have been in correspondence with "The Commodore Man", so I asked him to elaborate on the topic. Here is the two responses: > Yes, it's true.

Well, I can hazard a guess that the routines were the ones they had wanted to put in the 6522, but had to scrap due to the 6522 problem. Now I have no idea what the problem is/was, but I am eager to find out. However, I rescind my plans to build something around the 6522 until we find out what the problem is.

Or, barring that, >any specific links to the assembly instructions? Sure, some people on the net try to sell them, but they're easy to wire if you can find the DIN connector. I did one in a few minutes after digging for the DIN in the junk box. Worked the first time. See <http://ftp.funet.fi/pub/cbm/transfer/1541-to-PC/> for more info. I can't begin to tell you how easy and rewarding it can be to dig around on the web, following one clue to another. If you entered "x1541" or "1541 pc" in <http://www.hotbot.com> or any other search engine, or <http://www.dejanews.com>, I'm sure you'd quickly find dozens of references. - John Jefferson Computer Museum <http://www.threedee.com/jcm>
