Enlighten me: SE/30 PDS slot?

[JDW]

That IBM drive model number is suspicious. I can't dig up anything on it, so you need to determine the drive type from other info on the drive label.

Have a look at the drive label atop my 4.5GB IBM SCSI drive to see how I identified mine:




Now have a look at your drive's label again and verify if your drive is in this list (Hitachi now owns rights to those old IBM drives):

Well, I'm afraid that datasheet has me completely lost. I know pretty much nothing about reading this stuff, but here's the various bar codes/ID strings on the drive:

L1 B3B 192222

FRU PN 92F0428

EC895987

PN45G9490

E150455 LR34074 R9371775

SN 13 192222 S3

ESP2242411 FSP45G9883

EC 895964 4.0

Type 0662

Does any of this clear anything up?

 

[JDW]

Sorry, commodore, but I am completely lost by that data. And since I could not dig anything up on the original drive number (model no.?) that you provided, I cannot find out any descriptions for the individual jumper settings.

 

[commodorejohn]

Bummer. The only one I'm really confused by is "M," but the bigger question is what the Macs are looking for that the drive isn't giving them, which I don't understand at all.

 

[Dennis Nedry]

So you're saying that it doesn't freeze the Mac if you install it internally with termination on and SCSI ID 0, but it does freeze externally?

Do all versions of HDSC setup work with all drives or should we have Commodore put it back internally and try a different version that will see it? I am getting confused by the hackable Apple CD/DVD driver so I need some verification.

 

[commodorejohn]

Not 100% sure on that. When I install internally in the SE/30 with termination on and SCSI ID 0, it doesn't freeze, but HD SC Setup (patched version) fails to recognize it. When I install it in the external case and use it with the IIsi, it freezes the computer on boot unless I boot with it off, then freezes the computer when I turn it on. I haven't tried it internally in the IIsi or externally with the SE/30, though I suppose that might be worth a shot...

Can you post a picture of the drive? Something about those numbers rings a bell. Are you sure it's a 1 GB drive and not a 2 GB drive? IBM sold an odd ball 2 GB drive which showed up in a lot surplus type places for a while, which did not fit in their normal part numbering scheme. My memory says it was a 0664 instead of 0662 but how accurate is that memory likely to be? Anyway, the thing had a sort of frame around it instead of the solid cases we're used to now and was half-height 1.65" tall.

The thing about this line of drives is that there's no termination jumper. IBM shipped the drives with a pass-through terminator one could put on the ribbon cable at the drive connector, but those terminators all got lost by the time the drives showed up on teh surplus market.

Anyway, I have not read the whole thread, but I expect you have a termination issue. Folks might to attack it from that angle.

 

[commodorejohn]

Well, it was advertised as a 1GB drive, but I'll take a picture this weekend. If it doesn't have a termination jumper, it's certainly labeled like it does...

Guessing from the Type 0662 number,

[commodorejohn]

Well, the 50-pin jumper block detailed in there does look like the SMP variant described there. It's currently configured as device 4 with auto-start and active termination enabled; any ideas on what it should be set to, either in the SE/30 or as an external device for the IIsi?

 

[wally]

Just a guess...if you have that "Bottom Options Jumper Block for SMP Versions", try three jumpers to disable TI Sync Negotiations, disable SCSI parity, and disable Unit Attentions.

Anyone who is thinking about shelling out bucks for a long handled t-15, go to your nearest dollar store buy a t-15 driver (for a buck) then buy a 1/4 inch bit driver (for a buck) take the t-15 home and beat the handle off with a hammer or anything you can use to get to the metal part of the tool, completely remove the handle, select the correct socket to fit the end of the bare t-15 and you are done I've been using this setup for 17 years now, total cost is less than ten dollars No reason to pay $35.00 for a professional tool

and I can't get Lido on the SE/30, since it requires System 6.0.4 or later and I only have 6.0.2 and 7.5, which won't let me eject the boot floppy.

Don't forget that versions before 7.1 are available freely from Apple's web site:

the SE/30 runs at 16MHz, and the IIsi at 20MHz. Some cards will handle both speeds, and some will not.

Hmmm.

Has anyone ever tried the IIsi PDS-Nubus adapter on an SE/30 logic board? Nubus is 10MHz, which would be easy to derive from the 20MHz bus of the IIsi. It would (I think) require an independent timer to run on the SE/30.
