Yet another source lost to the dark side...

by jimw＠agora.rdrop.com

Well, yet another unwelcome discovery on eBay. For some time its been known that there was a person in the Albuquerque area (think he was a former MITS employee) that had some quantity of parts and some MITS equipment. Well, the parts business must not have gone well because it appears that he is dropping most of his stock on eBay as a series of auctions. Mostly bare boards at the moment. Business must be good... He did not even reply to an offer I made on a board almost a month ago... Grab what you see as soon as you see it... Or it will show up in an auction tomorrow! -jim --- jimw(a)agora.rdrop.com The Computer Garage - http://www.rdrop.com/~jimw Computer Garage Fax - (503) 646-0174

Seagate ST-506 DIP switch settings needed

by roblwill＠usaor.net

O.K. I just tried that. It doesn't work. However, when I close all the switches (on), and set it as drive 1 (straight cable), FDISK says it can't find disk 1. It does the same with a twisted cable (says the drive is disk 2) Should I try setting it as disk 2 and see what happens?

OT, but info needed: RAM uprade

by roblwill＠usaor.net

It probably depends on the system config. I have hardly any problems with IE, and have about every problem thinkable with Netscrape, but my dad's computer, which is slower, has a smaller HD, and less RAM, is just the opposite. Maybe it just doesn't like me :( -- -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1> -----Original Message----- From: Allison J Parent <allisonp(a)world.std.com> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Sunday, December 27, 1998 6:48 PM Subject: Re: OT, but info needed: RAM uprade > >I have 3.0+ down loaded off the net for free, is that too costly? it >runs on a 486DX2/66 with 20mb under win3.1 and it's solid.

Seagate ST-506 DIP switch settings needed

by roblwill＠usaor.net

Thanks! Now, this may seem like a dumb question, but, when I select a drive, or a factor default, I turn the switch on, right? -- -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1> > > ST-506 > Option Shunt Block > > ____ ____ > | |__| | > 1 | R | 16 > 2 | D | 15 > 3 | NC | 14 > 4 | H | 13 > 5 | DS4 | 12 > 6 | DS3 | 11 > 7 | DS2 | 10 > 8 | DS1 | 9 > |__________| > > Legend: > R Radial Operation > *D Defeat Recalibration > *H Half Step Option > DSn Drive Select > > * Factory selection > >Opening the Half Step option should improve access time. > >The proper interleave setting is a function of the controller rather than >the HD, so 3 should be OK. > - don > >

Seagate ST-506 DIP switch settings needed

by roblwill＠usaor.net

Anyone have the DIP settings for a Seagate ST-506 (full-height 5.25", 5 MB) HD? I can't seem to find it on Seagate's website (or am I just looking in the wrong place?) I'm trying to set it up as HD [0] on an IBM PC using a Western Digital XT-GEN controller. The HD appears to be recognized by the controller BIOS to do a LLF, but isn't recognized by MS-DOS FDISK (5.0 - I don't have anything smaller on 5.25" disks). It just says "error reading Hard Disk". I can only think of two things :wrong jumper settings, or wrong interleave setting. When I LLF'ed it, I left it at <3>, which is what was the ?default? was set at. Or is the WD-XT-GEN too new of a controller for the ST-506 (controller is dated 1987). One last thing: Does anyone have a 360k image (or TeleDisk Image) of IBM PC-DOS 3.0 or earlier (If you need a copy of TeleDisk, email me, and I can email you a copy). ThAnX, -- -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1> PS>> Anyone know what's wrong with the Obsolete Computer Helpline? It's been down for the past week or so. Looks like a main server blew or something.

Yeppers. I'm looking right at it (took the logic board off to remove a couple of styrofoam peanuts that were lodged between the drive and the board), and it says: SEAGATE TECHNOLOGY CONTROL ASSY 20040 EC and it has the little funky Seagate "S" next to it. -- -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1> > >Does the drive have a Seagate logic board? >The only ST-506 I have ever found was in a Profile drive with an Apple Logo >and had a Profile logic board. > >Hans > >

SCSI floppies - Wang drives

> >Get yourself a memory manager like QEMM. Or if you load DOS 6.0 you >should be able to use MemMaker to open up hi memory. Basically you need >to load HIMEM.SYS in your CONFIG.SYS to open up hi-memory for DOS and >stuff. > Well, the WANG has it's own special version of DOS 3.2 (or 3.3 - can't remember). I can't just load any version of dos on it, and expect it to boot. It had a special "WOS" (WANG OS) file or something that makes it work right. If I try to boot off of even another version of DOS 3.2, it won't work (even if the disk is formatted on the WANG). What's the lowest version of DOS that HIMEM.SYS works under (never tried it below 5.0)? One last (I think) about this thing: I've heard that it has an in-ROM word processing program, and a non-DOS operating system. How do I get to these, since when I got the computer, it was already loaded with the DOS-emulator.

OT, but info needed: RAM uprade

From looking at the suffixes, it appears that it would be the sx, but then, wouldn't that make a double-downgrade, and screw everyone? I'm just saying this, because I have (had - it's now parts) Gateway 386DX/25, and Compaq 386SX/20 (SLT386s/20). The Compaq could run more things quicker than the Gateway. Or is my case just a freak of nature or because of that majic stuff called Cache? -- -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1>

PC cassette interface and ROM BASIC (was Re: OT, but info needed: RAM uprade)

<What's better? The 386sx or 386dx.

Or is my case <just a freak of nature or because of that majic stuff called Cache? That was likely not cached. there are other parameters like memory wait states and external bus speeds that can affect the total throughput of any cpu. Allison
