Odd connectors (was: 'cross computer movers referrals)

The "GR" (General Radio) sexless connector is pretty common in really high-frequency stuff, but not quite as common as other (better-built, more expensive) sexless constant-impedance connectors such as the APC-7 and APC-3.5. What sort of connector are you trying to get to? -Dave McGuire

Saved from garbage truck : TRS80 Model II & disk system! Now keyboard and boot disk/software anyone?

by claudew＠videotron.ca

This is a lucky week for me. After the carload/motherload of Commodore stuff for $10 now this Model II working with Disk System! Spotted by a friend on the side of the street. Advised owner I would pass by and pick it up. I did. It works and quite restorable : no cracks, major missing parts or evidence someone played in it! I am in need of boot disks and software to try it out. It had one 8" disk in the computer drive and I get a BOOT ERROR TK message after the computer tries to boot (?) a solenoid seems to bring the head in close proxymity of the floppy twice after drive goes to outoor most track...and then I get the message. I suspect the disks in the drive is not a boot disk, disk bad or a floppy problem... Head was not moving so I moved the head stepper motor with power off. Step motor moved back to outside track at boot attempt. So that motor works... Disk says ACCOUNTS PAYABLE LABELS. Who knows if this should boot...... I am in need of a boot disk and a few software would be nice... I have also no keyboard. Does anyone know if a keyboard for a Model TRS80 model 2000 will work on this? I have one of those... I plenty to offer in trade or thank you gift. See trade list on my crappy web site...ask, I have more... Thanks for the help Claude http://computer_collector.tripod.com

EtherNEA

by optimus＠canit.se

Here's an interesting link for the Atari buffs out there: http://home.nexgo.de/thomas.redelberger/prj/atari/ethernea -- En ligne avec Thor 2.6a. We have support for the PMAGC-B's on pmax right? That is a PixelVision based card right? I see Bt 463, that chip looks bigger than the 21164! Just looking at it makes me want to write an Xserver! Chris Tribo, NetBSD/pmax

Sharp CE-515P plotter/printer - info?

by philpem＠btinternet.com

Hi, I've just acquired a nice little Sharp plotter/printer (model CE-515P). It seems to be in reasonably good condition and it works (to some extent). Only problem is, I don't have a manual. Does anyone here know what the control codes for this little thing are? I also need the pinouts for the RS232C port on the back. Also, does anyone know where to get pens and plotter rolls for this thing? -- Phil. http://www.philpem.f9.co.uk/ philpem(a)bigfoot.com

EACA Color Genie

by witchy＠vorbis.demon.co.uk

Hi folks, I thought there was only 1 version of this machine going by what I'd seen in magazines and the like, and I thought I had it already, but today I picked up another one in slightly better condition that has a VU meter similar to that found on the Video Genie I for tape loading purposes. I'm going to do a search now and a like-for-like comparison on tuesday (got to work my arse off tomorrow getting the cloakroom ready for the plasterers) but if anyone's got any insight that'd be smart. cheers! adrian/witchy www.binarydinosaurs.co.uk - the Online Computer Museum 0:OK, 0:1

HP 9000 DOS sw ?

by jarkko.teppo＠er-grp.com

Hello all! I was going through my old and embarassing posts on groups.google.com and found out/remembered that I have an HP 98286 DIO-I card for HP 9000 series 300. It has a 286 processor but unfortunately I don't have the software necessary to use it.. if anyone has the software I'd really like to know as I want to try some older games like Leisuresuit Larry on HP-UX :) (a nice game btw, I know of at least PC, Amiga and Mac versions. Might be more) -- jht

Someone missing a TI99/4?

by chris＠mainecoon.com

This is a little odd, but I seem to be in possession of a TI99/4 that was intended for someone else. Sometime the week-before-last a box turned up from Canada, addressed to me, with an import tag reading "PDP DEC Books & Parts", but which in fact contained a 99/4. I recognized the return address as being the guy that I purchased some stuff from some time back on eBay, so I sent a message asking where this thing was _really_ supposed to go and offering to help it on its way. The message didn't bounce, nor has there been a reply. I'm better that the odds are at least even that someone on the list did a deal to get this box. To that end, if someone can tell me what was included (there's more than a 99/4 in the box) and who the deal was done with I'll accept that they're the counterparty to the deal and send it on its way. Man, the things we do to preserve Good Collecting Karma :-) Cheers, Chris. -- Chris Kennedy chris(a)mainecoon.com http://www.mainecoon.com PGP fingerprint: 4E99 10B6 7253 B048 6685 6CBC 55E1 20A3 108D AB97

OT: Altair32: C arrays and pointers

by rcini＠optonline.net

Hello, all: Futher errors have been found in the Altair32 8080 processor emulator code by some eagle-eyed users. So, I'm trying to fix them, but my lack of depth in C programming has become evident. So, I'd like to enlist some help again. Here's the code (cut and paste; written by Claus Giloi): uchar regs[8] ; // A, F, B, C, D, E, H, L - actual storage order! // 0 1 2 3 4 5 6 7 // pointer array for sss, ddd addressing uchar * b_regs[8]= {&regs[2],&regs[3],&regs[4],&regs[5],&regs[6],&regs[7],&dummy,&regs[0]} ; // B C D E H L trap! ACC // pointer array for rp addressing ushort * w_regs[4] = { (ushort *)&regs[2], (ushort *)&regs[4], (ushort *)&regs[6], &SP } ; // B D H SP As you 8080 users know, several instructions operate on register pairs instead of individual registers. The instruction that began this odyssey was INX H. The INX B/D/H instructions increment the BC, DE, HL pairs. INX SP works. B/D/H don't. While the individual register halves reflect the proper values, the word registers are reversed. I guess it's because when accessing a word value in an array, the CRT code swaps the high-order and low-order bytes. So, I used the following code, which produces the desired result but is what I can only assume to be the sledgehammer way of doing what I want (lots of snipping): // u is the opcode and switch ((u&RP_MASK)>>4){ // RP_MASK isolates register pairs case 2: //HL tmpH = *pH ; // pointer to H storage tmpL = tmpL2 = *pL ; tmpL++; if (((tmpL & 0xff) == 0) && (tmpL2 == 0xff)) tmpH++ ; *pH = tmpH ; // save regs *pL = tmpL ; break ; // other cases omitted. } What I do is manually manipulate the byte registers (watching for rollover) to get the desired result, totally skipping the w_regs array. Bogus I admit, but it works. I can only imagine that there is a better way to do this. So, I'm asking for help finding the better way. Thanks again.
