Mac 512k complete set FS/Trade

by rhblake＠bbtel.com

In addition to the previous Apple/mac items message, I also have the following fine machine for sale or trade: --MAC 512k system which includes cpu/monitor unit with original 400k internal floppy, enhanced keyboard, mouse, printer, manuals, software and applicable cables. The unit was owned by a friend of mine since new and only needs a repair or replace of the floppy drive as it's getting old and sometimes doesn't read the disk, does other times. Great condition otherwise. Entire set $75.00 plus shipping or will consider trades (as mentioned in previous) or other PC compatible parts. I'll also include text on upgrading RAM to 1mb using common DRAMs piggybacked. Contact me if interested by direct reply... -------------------------------------------------------------------- Russ Blakeman RB Custom Services / Rt. 1 Box 62E / Harned, KY USA 40144 Phone: (502) 756-1749 / Data/Fax:(502) 756-6991 Email: rhblake(a)bbtel.com or rhblake(a)bigfoot.com Website: http://members.tripod.com/~RHBLAKE/ * Parts/Service/Upgrades and more for MOST Computers* --------------------------------------------------------------------

Apple Items FS

by rhblake＠bbtel.com

To update everyone, the Vector 3 has a new home and is on it's way there. I have the following Apple components for sale but will trade as well. You have to pay shipping though either way. * Apple ImageWriter II color dot matrix printer with good color ribbon and mini-din to 25 pin sub-d male adapter cable. The printer itself has a female mini-din connector. $40.00 plus shipping * Apple 5.25" external floppy drive set. Two drives that chain together, marked Drive 1 and Drive 2. Excellent condition. $25.00 plus shipping * SIMMS - 30 pin 1 mb non parity for Apple and Macs that utilize 30 pin SIMMs, not SIPPs or DRAMs. I have 8 of these. Seimens type with 5 large chips and two small chips. $8.00 for the set or even swap for 8 PC compatible 1mb 30 pin type. Items I might trade for: -CDROM drives, internal or external. IDE, SCSI or proprietary. Proprietary drives MUST include applicable adapter card. All should have any available manuals and software if possible. -Sound cards. MCA, ISA, VLB, etc. 8 bit or 16. Again, it would be best to have any available software or manuals if possible. -SIMM memory - 30 or 72 pin parity or non-parity, but MUST be useful in PC's and compatibles. I have no use for the Apple/mac types (hence the sale of the above). -486 motherboards, with processor. EMAIL directly to me for more info... -------------------------------------------------------------------- Russ Blakeman RB Custom Services / Rt. 1 Box 62E / Harned, KY USA 40144 Phone: (502) 756-1749 / Data/Fax:(502) 756-6991 Email: rhblake(a)bbtel.com or rhblake(a)bigfoot.com Website: http://members.tripod.com/~RHBLAKE/ * Parts/Service/Upgrades and more for MOST Computers* --------------------------------------------------------------------

I'm back! Now, who...?

by kyrrin＠jps.net

OK, I'm back from JPS Internet. Neat service! Now... based on the latest digest I got, it appears that someone (I'm not clear just who it is) has some MicroVAX II GPX video boards, cable, and mouse available for trade. Please get in touch with me if these are still available. The cable alone is worth the effort for me to obtain.

Sorcerer

Info needed on Microbee, System 80, Pencil II, TI 99/4

by scott＠isd.canberra.edu.au

I need some information on some old micros I have in my collection. They are all Australian models apart from the TI, although some of them made it overseas. Pencil II --------- The sticker on the base says this machine was made by Soundic Electronics, although I believe it may have been distributed by Hanimex. I need information on the power supply. I have been told it's 9.9V DC 1A and 17.7V DC 500mA, but I need the pinouts for the 3-pin DIN socket the supply is meant to connect to. Microbee -------- I believe the DIN socket at the rear right-hand corner is a combined power supply, cassette in/out and composite video out socket. Can anyone tell me the pinouts? System 80 --------- Originally this had an RF modulator, but the one I have has been very heavily hacked. Can someone give me the pinouts for the video DIN socket? TI 99/4 ------- Note that this is the 99/4, *not* the 99/4a. Can someone tell me the power supply requirements and pinouts? It is *not* the same as the 99/4a. I *think* it may need +5, -5 and +12, but I'm not sure.

Strange PCjr found

by SUPRDAVE＠aol.com

yes, i've seen one of those funky pcjr models too. i wish i had bought it just for the curiosity factor. i dont remember what brand the expansion unit was though. my particular pcjr has another drive in an external case with its own power supply and a cable going to the unit like an apple ][ In a message dated 98-03-05 18:37:23 EST, you write: << I was in a thrift store during lunch and saw a PCjr which had a second box attached to the top which contained a second floppy drive. This almost doubled the height of the system and there was a larger side car type box on the side as well. Any ideas as to what this may have been? Was it just for adding a second floppy maybe? I'm thinking about going back by and picking it up. They also had a VIC-20 with the VIC version of the floppy drive which I think I grab as I don't have one of those. >>

(he had run this one until very recently when he got a new multi-media system...) The computer has dual floppy drives, a cassette port and everything! Computer, Monitor, Printer, (all IBM) IBM DOS and other disks and all manuals! (Wordstar, Microplan, BASIC, etc. etc.) Haven't powered this one up but the previous owner says drive A has problems, but once running he could work off of B. (if anyone is interested in it an willing to pick it up, I will pass it along, otherwise it will go with me to VFC 2.0 (Hey, Sam, wanna raffle off a COMPLETE GENUINE IBM PC?) What I passed up on... Mac Plus Some Atari Stuff (800, 520ST, ST floppy drive) Commodore 64 stuff (never a shortage there...) PET 8032, 4040 dual drive.

Sol-20 revisited

by allisonp＠world.std.com

< Thanks Jim. Have you replaced the video ram in the Sol-20 before? < Also, do you know if parts are still available or will I have to < cannibalize from a similar vintage pieces part? < < Marty If it's a bad video ram swap it with the one next to it, if the pattern changes the ram is fried (I have tons of them). If the pattern doesn't change is likely a bad 74ls157 or 8097(74ls367). the test for a bad '157 or 8097 is to swap it with another on the board and see if the symptom changes. The fact that you've seen different patterns says the video rom is ok. Try popping out and reinstalling all the socketed parts and boards. You may have a crusty connection. Allison

Thanks to all for the hints, help and tips on the problem of getting this Sol-20 running. I fired this up last night but the screen didn't appear as I remember it last time> I must be losing my memory. All testing was done with the Sol-20 barebone, no S-100 add-on cards installed. The screen appears as such: $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ >$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ The prompt > is at the beginning of the second line, and this pattern is repeated in all 16 rows, save the second where the prompt appears. The upper case light and local light are on, the shift lock light is off. The keyboard doesn't respond except for the - key which is to the left of * on the numeric keypad section on the right. Next, I disconnected the keyboard cable (after powering down for a minute or so) and get the exact same result as above, less the upper case and local lights on of course. Finally (after powering off) I removed the SOLOS prom board and of course don't get the prompt > but get a new video display repeated from top to bottom of an equal sign '=' followed by a lightning bolt, this pattern repeats = then lightning bolt (I cannot reproduce the symbol) endlessly from top to bottom.

Demography

by Marty＠itgonline.com

William, I'd be interested in the Sphere, SWTPC gear, etc you don't want. Thanks- Marty Mintzell email: marty(a)itgonline.com ______________________________ Reply Separator _________________________________ Subject: Re: Demography Author: classiccmp(a)u.washington.edu at internet Date: 3/5/98 12:38 PM Well, lets see. I am 28 or so, living now in Carmel, NY (about fifty miles north of NYC), and like old things in general. Mostly. I am employed by one of the ISPs (originally the first ISP - the NSF) as an engineer. As you can probably tell by now, I tend to pick up the scraps of the network. I originally collected old radios. I had a small collection of consumer sets, some working, but dropped the hobby when two others came into my life - computers and old industrial/military electronics. The latter is simply from my consumer radio collecting days. The computers, however, probably started with the Apple II, like so many other kids in grade school. The first computer I ran into is my old DEC PDP-8/S, purchased "thru" a hamfest back in 1986. I was eyeing someone's PDP-11 boards (I was already a hamfest regular), and a man approached me with an offer I could not refuse - for $5, I could have a real, six-foot tall computer. I still have the machine. After that, I started getting others - mostly PeeCee and small mini machines. Sometimes they were pulled from dumpsters, other times they were purchased for a song. Right now, the collection consists of a PDP-8/S, PDP-8/E, PDP-11/23, PDP-11/34, Interdata 14, IBM S/1, IBM 5100, Sun 3/50, 3/60, 3/280 and 4/280, SPARCstation 370, SGI Iris 2500T, IBM RS/6000/T3B, and HP 2100A. Some machines work, some need work. There are parts of many others, but I am not counting those. I also have a bunch of ancient Sphere/SWTPC/Exorsisor stuff that I need to get rid of (I have no interest in it). Most of it will migrate to RCS/RI (so Allison can play with it). In addition to old computers, I collect old Naval radios and radar sets from the 1930s and 40s, as well as vaccuum tubes. At this point, I do not know which collection takes up more mass, as some of the shipboard radio transmitters are six foot monsters as well. Look at some of the old serials from the 1950s - they tend to show up as props in monster labs. And I do not play bassoon. I also voluteer time as part of the restoration crew on Battleship Massachusetts - a place with _real_ computers. Sorry guys, but engineering and craftsmanshipwise (is that a word?), the mechanical fire control computers are far more impressive than any of the digital stuff.

Demography

by jthiemann＠castleton.com

While we're at it (the buisness of veering grossly off-charter), who else here collects electronic music equipment of about the same vintage as the computers discussed here? I have a Korg Poly-800, Yamaha DX-7II, 2 FB-01's, CS-01, a Sequential SixTrack, 360 Systems MidiBass, and a homebrew MIDI interface to hook some of this to my Amiga. I have grandiose plans (ok, ok, not _so_ grandiose, but everything is relative these days...) to rip the 6581 out of my C64 (or better yet, find an old otherwise nonfunctional C64 and rip the 6581 out of there) and hook it up to a 68HC11 SBC I designed a few years back (the company I used to work for is still using and occasionally producing these) and controlling it (the 6581, that is) via MIDI as a cheap-o (and physically small) analog synth. (Cause let's face it, that's what the 6581 is...) BTW Any of you UK guys have collections of the old E&MM magazine? I'm missing 1 or 2 issues in the 84 (83?) season... -------------------------------------------- Joachim Thiemann DSP Coder, Castleton Network Systems I doubt therefore I might be. > -----Original Message----- > From: R.

DEC GPX II Q-Bus boards

by jthiemann＠castleton.com

I think I have that card set (but not the roms - but I do have a spare ka630 board) with full instructions. I can dig up specifics over the weekend, when I'm back in Montreal. My uVaxII does have the ability to act as an X client - I tried it, I have the 3 Tk50 Ultrix distribution set (but who wants that if you can have NetBSD?) I think it can drive the GPX cards too, but have never seen it do so myself - I don't have a monitor to hook up to it. If anyone wants the cards (the GPX and the spare ka630), they're up for grabs - either for sale or trade since I'm not doing much with the VAX (I like my Sparc better) -------------------------------------------- Joachim Thiemann DSP Coder, Castleton Network Systems I doubt therefore I might be. > -----Original Message----- > From: allisonp(a)world.std.com [SMTP:allisonp@world.std.com] > Sent: March 4, 1998 22:06 PM > To: Discussion re-collecting of classic computers > Subject: Re: DEC GPX II Q-Bus boards > > <I have a three board set of Q-bus cards plus the boot ROM for a uVAX > II, > <dated from 1987, which supposedly turns a VAX server into a > workstation f > <DECWindows.

Info needed on Microbee, System 80, Pencil II, TI 99/4

by adam＠merlin.net.au

>Microbee >-------- >I believe the DIN socket at the rear right-hand corner is a combined power >supply, cassette in/out and composite video out socket. Can anyone tell me >the pinouts? I have one of these, but I'm afraid I can't help - the version you speak of should be the Microbee 64 with the Computer-in-a-book combined disk/drive power supply etc. I only have details for the 16k version. Nevertheless I'll try digging them up and see if they help, but hopefully someone else will be able to tell you more. The manuals I have lack details. >System 80 >--------- >Originally this had an RF modulator, but the one I have has been very >heavily hacked. Can someone give me the pinouts for the video DIN socket? I can do this. :) Going on the diagram I have here, we have: 3 ---- ---- 1 / \ / | \ / | \ 5 | 4 2 where 1 is +5v, 4 is video output, and 5 is ground. I have most (if not all) of the manuals for the System 80, including some doubles here. Adam.
