This works as I expected. If I want to go back or go to an absolute location, I have to switch to RUN mode and do a GOTO from there, then switch back to PROGRAM mode. -Frank McConnell

HP 9100 programming questions

by fmc＠reanimators.org

Howdy, I am fooling with a 9100B calculator that used to be on exhibit, I'm guessing in the electronics museum that used to be at Foothill College. Toward that end it was hacked: a plexiglas strip was screwed to it above the switches, with cutouts for the switch handles that only let you move the power switch -- program/run, fixed/floating, and degrees/radians were all stuck on run, fixed, radians respectively. Well, I've removed that because I want to find out what if any programs were in its memory (core remembers things long after they're better forgotten), and so I want to flip the program/run switch over to PROGRAM. But I'm a little confused about the 9100's program mode, and unfortunately I don't have the manuals handy. When I flip the switch to PROGRAM, the display changes to what I am guessing is this: <step> <instruction> <Y mantissa> <Y exponent> <X mantissa> <X exponent> <step> seems to be represented as <hex digit>.<hex digit>. True? (And does this mean there are only 256 program steps?) Are <instruction> values 00-09 the keypad switches 0-9, and others in <column><row> form? And if so, where's <0><0> for the <column><row> form? Can I use the STEP PRGM key to single-step forward non-destructively in program mode? How can I move backward, or to a given location in program mode? Can y'all tell I'm spoiled rotten from having learned programmable calculators about 15 years later? -Frank McConnell

DEC-10 comparative power

by dseagrav＠bsdserver.tek-star.net

About how fast is a DECsystem-ten compared to a Pentium or something? A friend and I got into a "whose computer is faster" fight. I have the 11/23, he has a Vaxserver 3100. I have the 44, he has his Pentium/something.(133 or 150?). I have a shell into a DEC-10, does that beat him, or do I lose? (I think it does, does anyone have the numbers?)

HP-150 disks...

If any is a DOS disk, there was a post recently... bcumming(a)mail.island.net wants DOS 3.2 or might be interested in some disks. manney >I just picked up 34 'Hewlett Packard 150' diskettes; except for one >they are all user labeled (Well I THINK they are all HP-150 disks, the >disk type and labeling are very similar.)

Advanced Integration Research Motherboard

by manney＠nwohio.com

Normally, 486 motherboards are set entirely in the CMOS setup program. Jumpers, etc. typically control speed and processor type. Are you having trouble getting it to come up? manney(a)nwohio.com >I have a 486lc motherboard and need to know about any of the settings >(i.e. jumpers and dip switch) and what the memory config is. thanks

New update on Comprehensive Computer Catalogue

by hans1＠filan00.grenoble.hp.com

Today I place the new version of the CCC online. Now listing 3806 computers. In this revision I have set up the infra structure to link each system to its own page. The intent is to provide information and links for each system. See the entry for the Sperry SPEEDAC computer. BTW anyone heard of the ULTRAMAC computer built in the mid fifties? -- Hans B.

HP-150 disks...

by adam＠merlin.net.au

>It could make "Classic" tenuously on either one and, given both, has NO >problem. Now -- what I keep wondering about is an Atari Portfolio (1989).... I have added it to my web site, based on a) being obsolete, b) being a new concept for its time (first MS-DOS palmtop?), and, of course, c) being really keen. Anyway, 1989 is even starting to get old in computing terms. Adam.

The HP-150 is: 1) vintage 1984, and 2) absolutely fascinating. It could make "Classic" tenuously on either one and, given both, has NO problem. Now -- what I keep wondering about is an Atari Portfolio (1989).... __________________________________________ Kip Crosby engine(a)chac.org http://www.chac.org/index.html Computer History Association of California
