I recently found a large number of hard sectored 8" disks and I was hoping some one might knows what computers would use these disks. * Dysan 3740/2D, Double sided, Double density, format: 128 bytes/26 sectors, index 1 & 2. (I don't know if these are hard sectored. There is just one index hole in the disk but two index holes in the jacket) * Memorex 3201-3015, Compatibility: Shugart, Write protect, Single sided, Single density, Sectoring: 32 hard (Just regular 32 sector hard sectored disks) * Memorex 3071-2003, Single sided, Single density, Sectoring: hard * Verbatim FD 65-9000-HR, Single side, Single density, Vydec/ Memorex compatible. (These have 33 index holes in the disk, but they are arranged around the out side edge of the disk. Also there is a 1 1/2" x 1/2" notch cut out one of the corners of the jacket.) I could not find a web page for Dysan, I searched Memorex's and Verbatim's pages and I emailed Memorex and got no reply. ========================================= Doug Coward dcoward(a)pressstart.com Senior Software Engineer Press Start Inc.

Apple //gs composite video prob

by red＠bears.org

Hi. I just picked up a ROM v01 //gs at a thrift shop. The colour composite video it generates is very badly artifacted. On my ][plus, there is a 'colour trim' adjustment which I would expect to correct this on the mainboard, but I didn't see anything like this on the //gs. Also, the colours are pale and incorrect when I use my Apple // RGB monitor (the one with the electric tilt) on the RGB port. This monitor doesn't work on the RGB port of my //c at all, so I'm wondering if it's just a matter of not being quite the right monitor for the //gs (which has, if I recall, a monitor more closely styled along Mac lines). Thoughts or hints? ok r.

Depends on the situation - If I don't have it (the money), I would just pass. If it's a single talk, I would try to barter for the price. If its a competition, I think I'll have to pass since USD 1000 wouldn't be the last call. > Whenever I see a system I want, I go through several rationalization > exercises.

Hmm, don't fit my intention - 10 minutes of 'boh ey' it's mine could be more worth than 0.5 USD :) One of the nice things in collecting old computes and other stuff is that one could find things _unbeliable_worthy_ for zero money (or almost), since the value ist more determinated by our private idea about this particular thing. Example: I aquired some weeks ago two sealed ROM cards for the Apple II. They are just cheap (custom) ROM boards covered with blue resin (? Giessharz in German - don't know the exact term in english). Early designs of softwareprotection true hardware. They are complete worthless in any sense, but I enjoy it a lot to own them. So, whats the price ? If the owner had asked 20 USD, I would never had paid it. Gruss H. -- Ich denke, also bin ich, also gut HRK

Misc. DEC Boards

by peacock＠simconv.com

While checking some boxes in the computer room, I found these old spare DEC Q-Bus parts. They actually belong to the company but if you are willing to pay shipping plus trade something (cash is ok too) I can let them go. AFAIK all boards were pulled from working systems several years ago. Contact me at peacock(a)simconv.com MicroVAX I board set and cabinet kit (serial console connector) 4MB third party Q-BUS memory card, no RAMs (takes 256K DIPs), works great w/uVAX I CPU (you need VMS 5.0 for this, 5.1 and later not supported) ------------------- 11/23 CPU board and cabinet kit (2) DEC memory boards (I think 256KB and 128KB, not sure) both memory boards were with the 11/23 ------------------- MicroVAX 3500 CPU (KA650) board, no cabinet kit (might have it, not sure) (2) 8MB memory boards for the KA650 (this CPU has the older boot ROM, no SHOW command) -------------------- KDA50 disk controller 2 board set (was with the 3500) -------------------- RL02 Q-Bus disk controllers (2) I think RLV21s, have to look -------------------- 12MB expansion memory for a VAXStation 2000 -------------------- (6) DEPCA ethernet boards for ISA bus, old ones w/48KB buffers (all modified for Pathworks drivers) If you have stuff to trade, I could use any of the following: TK50 drive w/SCSI interface (TZ30 or TK50-G) internal preferred 16MB 72pin SIMMs (x32 or x36, EDO or FPM) IDE or SCSI disk drives 1GB or bigger 4mm or 8mm tape drives a flatbed scanner that works with Win95 a Q-BUS IDE or SCSI disk controller useful S-100 boards (tell me what you got) Atmel 89C2051 ucontrollers a monitor that works with the GPX board set in a uVAX II Cyrix 686 or Pentium 166 CPU chip (working on a flaky Motherboard) 33.6 modem ISA card that works with NT4 memory for an Alpha 500au or if you have something else to trade, let me know, make an offer. not interested in consumer computer stuff (i.e. apple, IBM PC, amiga etc.) Jack Peacock

Whheee! Saved from a dumpster...

by rexstout＠uswest.net

Saved a Compaq Portable(w/5.25" FD and unknown 5.25" FH HD) from a dumpster... AFTER a 10 foot flight into it! Plugged it in and it still works... Needs some repairs, I can hear stuff rattling around inside, but it does work... Booted from the hard drive with Compaq DOS 3.31. Also got a MasterSport 386SL(386SX-20, 4MB RAM, 63MB HD) and a 486 motherboard(gonna set it up with Linux or something). Also getting a 1970 VW Bug for my birthday next week... I suppose this makes it a good day despite the belt clip on my radio breaking this morning(now I get to make a nice metal one to replace the broken plastic one). -------------------------------------------------------------- | http://members.tripod.com/~jrollins/index.html - Computers | | http://www.geocities.com/Area51/Lair/1681/ - Star Trek | | Orham(a)qth.net list admin KD7BCY | --------------------------------------------------------------

QuantumLink AOL lore...

by foxnhare＠goldrush.com

Actually... Quantum Computer Services started off Quantum Link from the old Commodore 64 Play-Net network and later developed Apple and PC link as those developed (from the old Q-Link system) Quantum Computers changed their name to AOL and later shut down the Commodore Q-Link service after leting it suffer a slow-agonizing demise for a few years. Pitty, it was a good service. There are still a bunch of Q-Link ideosyncracies in the system such as 10 character screen names. There is a web page out there that gives the whole story, I came across it a while back in my surfing. Hopefully Doug Coward will read this and fill us in better, as he was an actual Q-Link employee for many years (read he actually worked there, not a Q-Guide or some sub-op position). -- -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- Larry Anderson - Sysop of Silicon Realms BBS (300-2400bd) (209) 754-1363 Visit my Commodore 8-Bit web page at: http://www.goldrush.com/~foxnhare/commodore.html -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-

Never pass an $8 computer [Apple IIc swapmeet story]

by thomas100＠home.com

Hi, So I bought two Apple IIcs last year, one from at the Capitola Swap Meet for $8 with no power supply and a bad keyboard and the other at a ham radio swap meet for $15 with the cute little monitor, stand, power supply, TV adapter, printer and a bunch of other junk [Printshop and... what a thrill- typing tutor!] I bought the two machines some time apart from each other and was moving about the time I picked up the second. So finally today I found that the first one work while the complete system I bought is broken. Well... it's no problem since I can make one working model out of two. Fortunately the first one also has a case with no yellowing problem. The moral of the story: Never pass up a $8 retro-computer... even if it's broken and incomplete! Thomas

I was just getting to the point of trying to 'backup' the software (disks), and look around in the system, and the 12v portion of the power supply died. No 12v, no boot.
