AS400-C10

by xds_sigma7＠hotmail.com

Hi, Well I can at least confirm that the disk drives are SCSI, since I've been looking at an AS/400 that I know contains only SCSI disks. That model of AS/400 is old enough that it does not use the PowerPC chip, I know it uses some other kind of RISC chip but can't tell you what.

8089 was Re: Hyperion Passport, Apricot, Convergent Technologies workSlate,

by edick＠idcomm.com

Well ... that i8089 has to be a slave processor to something else. The notion of CP/M for something other than the "BIG-3" i.e. 8080/8085/Z-80, seems unnatural to me. I you can find an OS that actually uses that i8089, I'll be surprised, but really interested. I've got one on an Intel iSBC215 "Versatile Hard Disk Controller" intended for goodness knows what, which I mistakenly bought back in the early '80's, thinking it would do something "wonderful" and worthy of study since it was so expensive. -Not so! - The 11-bit bit banks in those memories are halves of 22-bit words which are SECDED compatible for 16-bit words of data. Intel made a chipset to accomplish just that and it's probably the set on your board(s).

how many heads, Cylinders on a Quantum 540?

by edick＠idcomm.com

Yup! That was a bad spec! I see where there are several Quantum drives with the 540 as part of their model number. This is the old Q540 form back in the '80's, though. It looks like it's going to be rubbish, though, except for the socketed MPU's which will go in the parts bins, since, (whine) it doesn't seem to work. Dick -----Original Message----- From: John R.

how many heads, Cylinders on a Quantum 540?

by edick＠idcomm.com

No offense, Allison, but the 1007 and 1005 controllers won't work with that drive at all, as both 1005 and 1007 are ESDI controllers. You may be thinking of the 1006's which come in both MFM and RLL. The 1006 WITH an EPROM on it is the RLL version, while the MFM version uses the motherboard-resident BIOS to handle the HDD. ESDI is a high-level interface not at all like the "ultra-dumb" ST-506/ST-412 interface this drive claims to have, though it does use cables of similar configuration, hence has similar connectors. This drive is commonly used with MFM, though its speed control, etc, is capable of RLL densities as are most "MFM" drives.

I've seen occasional mention of the quantum 540 HDD on the list. Has anybody got the cylinder and head count available? thanx Dick

Olympia Olytext 20 OS question.

by ernestls＠home.com

I have an Olympia Olytext 20 computer but I don't have the OS for it. It's a single board, Z-80 system, with a 3.5 inch FD. The manual said it used CP/M-80 but I haven't been able to find any other information on the system, or the OS. No one that I've talked to knows anything about this PC, so I won't even hope that anyone here would have the OS but... I'm wondering if there is a way to make a new copy of the OS for this system? If I can find out the hardware addressing, etc., can CP/M 80 be made to run on it, and without a horrific amount of work? (I know, depends on what I consider a lot of work.)I don't mind tedious, if it's do-able. I've never done it before, and some of you may be chuckling about it but I'm just curious? Otherwise, this computer will just continue to sit, unused, on my bookshelf. Ernest

AS400-C10

by zmerch＠30below.com

Rumor has it that Paul Thompson may have mentioned these words: >The IBM site is not forthcoming on additional details on the machine. >>From a quick once over the disk/DASD appear to be SCSI, as does the QIC >tape. Can anyone confirm? Sorry, no. Haven't seen the innards of an AS/400 much... >Any other information would be helpful as well. I will probably be >spending the evening looking for recovery procedures for lost >"root/system/whatever" password...what is it on the 400? AFAICR, one of the most powerful logins is QSECOPR (security operator) and should have access to darned near everything (if not everything) on the system. I have a friend that did a *lot* of work on the AS/400's and might be able to lend a hand... I'll ask tomorrow. HTH, Roger "Merch" Merchberger -- Roger "Merch" Merchberger --- sysadmin, Iceberg Computers Recycling is good, right??? Ok, so I'll recycle an old .sig. If at first you don't succeed, nuclear warhead disarmament should *not* be your first career choice.

<The notion of CP/M for something other than the "BIG-3" i.e. 8080/8085/Z-80 <seems unnatural to me. I you can find an OS that actually uses that i8089 CPM86, 8086/8 would use it as a slave (8089) assuming the bios was written for it. Though I do have a z80/8089 paper exercise that would work. the 8089 never had it's own OS or anything like that. Iwas basically a channel processor for IO. <I'll be surprised, but really interested.

by allisonp＠world.std.com

< Hi Tony, I have an 8089 in a CPM machine but I haven't been able to fin <out much about that chip. What can you tell me about it? 8089 is an IOP (IO processor). It is a super intelligent dual DMA channel and 20 bit cpu combined. I have a few and docs. It can run 8 or 16 bit busses in local or remote modes (or mixed). Commonly used with 8086 to offload the cpu from taking IO interrupts and doing high speed interfaces. While it could be used as a general purpose processor the instruction set and stucture was more for moving data (or tables of data) than arithmetic. < FWIW the same machine has ECC memory controller in it too but I don't <remember it's number. Memory is in banks of 11 ICs! Likely the 8206 or 8207 Allison
