16 bit 6502?! No, you don't want it... trust me!

Epson QX-10 / AT&T 3B1

by cgregory＠lrbcg.com

VALDOCS is an early example of a "works" type program for CP/M although its most noteable module was the spreadsheet. My wife liked it much better than Lotus 123. I have both a QX-10 and a QX-16. They are both quality boxes. The QX-16 is especially fun because one can boot it in either CP/M or MSDOS. I would encourage anyone to rescue examples of these fine machines. If I didn't already have one, I would be tripping all over myself to obtain a fully documented QX-10 for $65.00. In fact, if you decide to pass, let me know who to contact; I wouldn't mind having a spare.

Demography?

by adam＠merlin.net.au

My turn. :) I'm a collector in Adelaide, South Australia - not the only one here, but one of a very small number. I'm 28, and until very recently I was a student, doin a Masters in Philosophy. (In case anyone cares, my thesis concerns the ethical status of hypothetical artificial minds - basically I'm looking at the criteria for ethical value employed with people and in animal ethics, and working out whether that criteria can be met by an artificial intelligence). As far as occupations go, I have a few (being a typical long-term student) - I'm a welder, do some web page design, some internet consultancy, Perl coding, teach ethics and critical thinking to nurses, actually get paid to MOO, work occasionally as a human guinea pig in medical tests and I am a professional Teddy Bear artist. :) I've worked in a few other areas, but they'e the most recent/current ones. Anything to pay for more computers. I started collecting late last year, although I had wanted to for ages. My first computer that I used was my uncle's Microbee - an Australian Z80 kit computer - but I rapidly moved to the TRS-80 Model 1 and Vic-20. Last year I was offered a Lisa 2/5 to save it from being scrapped, so I figured it was about time I went and picked up all the old computers I wanted when I was younger. Mostly I only get Micros, but I do branch out - it seems that I'm getting my first supercomputer soon. :) My current collection consists of (from memory - I'll probably miss a few): Amstrad CPC6128 (x2) and Notepad NC100 Apple ][+, ][e enhanced, ][e platinum, ][c (x6), ][gs, ///+, Lisa 2/5, Mac 512k Atari VCS, 400, 800, 800xl (x2), Portfolio Commodore VIC-20 (x3), 64c (x2), SX-64, 128, PC-10 DEC Microvax II Dick Smith Electronics Wizard, Dick Smith System 80 (x2), VZ-300 Exidy Sorcerer Honeywell Microsystem 6 (I'm still hunting for any information about this one). IBM PC/XT Mattel Intelvision Memotech MTX-500 Microbee 64k Sharp MZ-721 Surwave Amigo Tandy TRS-80 Model 4P, CoCo 1, CoCo 2 Wang 286 And today an OSI Challenger 4P arrived. :) Keen. My bigest wishes at the moment are for a NeXT Cube, and Apple ][c+ and a Spectravideo 318/328. Adam.

NEC APC

by cprohman＠ix17.ix.netcom.com

A seach of the Web yields numerous hits on "NEC APC", many of which are >from cable companies. You should have no difficulty in finding cables for the computer. I can tell you that the APC indeed belongs in your museum! If there ever was a machine which stood out as before its time, that is the NEC APC. The monitor was high resolution color (I hope you got the color version) at about 640x480 if I recall. It had a dedicated graphics chip which could do line drawing, curves, etc. It had about a 102 key keyboard. It had a 1MB floppy (8", of course). It had a sound chip and integrated speaker capable of reasonable music. Does yours have a hard drive? The early hard drives were 10MB externals, by the way, so you no doubt have some kind of external connector for that as well. Many of these advanced features later (or much later) were added to the PC. IBM eventually came out with EGA, which nearly matched the APC. With the AT they nearly matched the APC's keyboard (though they still neglected putting an "ENTER" key on the keypad), and surpassed the APC's floppy capacity. It took many years though before the PC added sound cards with better capability than the APC, or graphic accelerators with dedicated graphics chips. Too bad that your APC didn't come with documentation. The APC shipped with the best documentation I have ever seen, including internal schematics, a decription of all internal logical features, and a even a full listing of the BIOS on a disk. The documentation allowed me to write for example an interrupt driven print routine to replace the timing based BIOS print routine. Using my print driver the APC was capable of fully driving a 300LPM printer, or capable of driving a 100cps printer while simultaneously doing a program edit. Try that on an early PC! I hope you got some software. The original disk included a program "BACH", which demonstrated its musical prowess. Later machines shipped with a simple program I gave to NEC called "PLAY" which allowed the machine to play music coded into a text file which listed the notes to be played and the duration of each note. Usage was "PLAY filename". Banjo music worked particularly well. There was also an impressive program that demonstated its color graphics potential. Carl

Sorting arrays(could be considered off-topic)

While I am making this program in Visual Basic 5, this problem is way over 10 years old, and the program will be old computer-related. How do I alphabetically sort an array? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

I ran into a wall again...

by DSEAGRAV＠toad.xkl.com

Closer... I installed the DH11 along with that ACT thing in the 44. Now HARDWR LIST says I have 2 DHes, and a DM. But hanging a terminal off the ACT thing yields absolutely-fscking-NOTHING. I don't have the origional DH11 distribution panel. But I have the wires that are supposed to attach to it... Can I modify a DZ11 distrib panel to use in it's place? Do I need to modify CSRs or something? Oh, and I already tried all possible combinations of cabling 'tween the ACT board and it's panel. On a sidenote: Anyone know how to break into an IBM System/34? -------
