Ben. *-------------------------------------------------------------------------* By chance, it just happens that I do... Wyse, Lear Siegler, Falco or Cromemco, what's your pleasure? Also a TransTerm & some other oddball stuff. The L-S ADM11 would be my recommendation. As to the cassette drive, I wasn't entirely serious in suggesting it; it's a very non-standard Burroughs interface and I think it would be more work interfacing that than your whole computer project including the cassette interface. But if you're looking for a *real* challenge.. The PPT stuff also uses proprietary parallel interfaces, Burroughs and SCM (CDC?), but that would probably be a lot easier to do. Looks like the AC-30 may be spoken for. Did you get enough info on interfacing the cassette, or want me to scan something for ya? If you could really use any of this, contact me off list. mike -------Original Message------------ Date: Mon, 29 Oct 2001 07:46:14 -0700 From: Ben Franchuk <bfranchuk(a)jetnet.ab.ca> Subject: Re: Almost on topic - Cassette I/O By chance you would not have a terminal too?

Apple II SCSI card

by paul＠orchard.wccnet.org

Rich Beaudry: You have an Apple II Rev C SCSI card, not the High Speed card. Below is a comp.sys.apple2 post with more details about the card, including some limitations. I have one in my IIgs. I also have the original manual and software, but the Chinook SCSI Utilities (CSU) software is better (see below). I can provide you with copies of this stuff. I can point you to online sources of disk images if you can handle them. For others with Rev A or Rev B versions, I can make Rev C EPROMs. Paul R. Santa-Maria Monroe, Michigan USA From: David Empson (dempson(a)actrix.gen.nz) Subject: Re: Apple II SCSI Card rev C - Latest Revision? Newsgroups: comp.sys.apple2 Date: 1998/09/11 Brian <brwiser(a)xmission.com> wrote: > I just acquired an 1996 Apple II SCSI Card revision C, for my ROM 1 > IIgs. I think you'll find that date was 1986, not 96. :-) > Is "C" the last revision of this card? There is only one version of the physical card. "Revision C" refers to the firmware version. The ROM should be labelled "341-0437-A" if it is revision C. Revision C is the last release of the firwmare for this card. > Are there any problems I should be aware of? Many. Where should I start? 1. The card is not terminated. If you are connecting more than one device, you must place a pass-through terminator between the card and the first device (or internal termination in the first device), as well as after the last device on the chain. If you are connecting a single device, it should have internal termination or a piggy-back terminator. 2. The card does not supply termination power. There is a single diode modification that can rectify this. Another option (my preference) is to make sure that at least one of the connected devices is able to supply termination power. 3. The firmware is limited to seven logical partitions. These partitions may be spread over as many as 7 SCSI devices connected to the card. Under ProDOS-8, this gives a practical limit of 224 MB accessible over all volumes. Note that you need to be running ProDOS-8 2.0.1 or later to be able to access more than 4 partitions, and this requires at least an enhanced IIe. Under earlier ProDOS versions, you can only access 3 or 4 partitions if the card is in slot 5. The seven partition limit does not apply under GS/OS, which uses its own drivers. 4. The firmware doesn't fully support removable hard drives, including devices like ZIP drives. The problem is that if you switch disks, the firwmare does not update its saved copy of the partition table. This can easily result in corruption of the new disk if it is not partitioned EXACTLY the same as the previous one (right down to the starting block number and number of blocks in each partition). This problem doesn't affect GS/OS, and you can work around it under ProDOS-8 by rebooting if you need to change disks. Note that if you boot via GS/OS and then get into ProDOS-8, quitting to GS/OS and relaunching ProDOS-8 might not be sufficient to reinitialize the firmware (I haven't investigated this). 5. The firwmare only supports SCSI hard disks and CD-ROM drives. CD Audio operations are only supported with Apple's original CDSC, CDSC+ and CD-150. This isn't likely to be a major issue. 6. The card is slow. The Apple High-Speed (DMA) SCSI card is a lot faster (as long as DMA can be used), and the RamFast is even better. 7. The partitioning software that comes with it is pretty limited. If you didn't get the disk, this isn't an issue. A much nicer 8-bit alternative is Chinook SCSI Utilities, which is now freeware. (I don't know of a source for it off-hand.) You can also use Advanced Disk Utility under GS/OS. -- David Empson dempson(a)actrix.gen.nz Snail mail: P.O. Box 27-103, Wellington, New Zealand

Re. Hunt for DRV11-WA / DRV11-SA Field Maintenance Print Sets

by Lowndesz＠aol.com

To whom it may concern, I am trying to find Field Maintenance Print Sets for the following cards: - DRV11-WA - DRV11-SA I would be most grateful if you have any suggestions as to where I might find these. Many thanks, Kathryn Stewart l P.S. We are posting a reward of a bottle of French champagne for originals or good copies of the above two sets of schematics - thanks.
