Actually, the worst damage possible has already occurred. If it happens again, it won't do much additional damage, aside from loss of in-plant life. The surrounding area is already lethally contaminated. A fossil-fuel powered plant would create as much environmental damage over the six or seven years between major incidents, so I don't see this as a major risk to us. Now, if I lived nearby, I might feel differently. Dick -----Original Message----- From: Daniel A.

They put these really unreasonable price tags on stuff, and when they don't sell, instead of lowering the price, they pitch it! I watched a whole pallet load of 8" FDD's for example trashed because no one wanted to pay $25 apiece. But then, theres this stuff that they totally don't have a clue about, that's like, *really* valuable, they sell at give-away prices. Wierd.

CP/M-80 drivers for WD33C93 ???

by edick＠idcomm.com

It would be interesting to see SOMETHING for the 33C93, but what puzzles me more than anything else is the question of how to cook up a quick and dirty translation from the CP/M drive/track/sector specification to a logical block structure as is used on SCSI/SASI devices. CP/M 2.2 is so much nicer if you have a maximal TPA which won't happen if one's using table lookups and stuff in place of computations to determine which block contains what the OS is in sector ss of track tt on drive x. You see, if this is implemented on a bridge controller which talks SCSI to the system, but whose drives are ST-506 interfaced, there are good ways and bad ways to allocate blocks. It's simple enough to do one layer, but if you have to deal with two, how you do one will have substantial impact on how the other works out.

CP/M-80 drivers for WD33C93 ???

by allisonp＠world.std.com

<>Has anybody got a CP/M-80 BIOS driver example for the WD33C93 SCSI <>controller? I'd surely like to look at one or two. Format utility stuff <>would be good, too. The only SCSI drivers I've seen for CPM-80 are for discrete (SASI) and NCR 5380 chips. I've heard the 33C93 is a really buggy chip. Allison

Commodode elected to use the WD33C93 with the autobooting SCSI cards - A2091 and up including the A500 slap-on A590 (either SCSI _or_ XT-IDE drives would work on it owing to Commodore's custom controller chip between the Amiga and the 33C93) and on the motherboard of the Amiga 3000. The wisdom in the Amiga arena is that even though C= shipped rev 02 and rev 04 chips, you need the last version ever produced (rev 08?) to take advantage of proper disconnect/reconnect operations and to have a full 7-device chain. The older chips work OK if you have one or two disk devices, but have problems with four or five disks, a CD-ROM and a tape drive. There is example code for the WD33C93, not for CP/M, but for (Net|Free)BSD on the Amiga. Also, if anyone is looking for a few rev 02 chips, I have a tube of them that I'm keeping as Amiga spares. I could let a couple go, depending on how much over shipping I'm offered. -ethan ===== Infinet has been sold. The domain is going away in February.

PDP-8 toggle-in diags (was Re: LET'S (old topic)/and PDP-8I code/update)

I worked on the -8/e for several hours last night (and gave a tour to friends). I even powered up a couple of -8/L's to see how they were (mis) behaving. One has a bad M220 card (can't load one of the MA bits from the switch register, but incrementing the address does work), neither works perfectly (and a third is sans core :-( ) I'm taking my Tek 465 and a TTL/CMOS IC tester out to the computer barn to further my efforts. I built a cable with a DIP header on one end and a DIP test clip on the other so I can quickly test M-series flip chip (at least the simple ones like the M111, M113, M216, etc.) I have to scope out the complicated ones like the M706/M707 I/O cards, the M220 register cards, etc. > The most important useful <1 page programs I have had to write (over the > past day) are: > tty continuous output generator (character selected on SR) Ah... I just wrote one of those... BTW, your mem test program has a typo... the 7064 instruction (LAS) should be 7604. It threw me for a while until I could get things sqare. I'm still re-learning machine code. I didn't notice that 7064 _couldn't_ be the LAS instruction (wrong group). My TTY banger has an extra feature for the -8/e - it counts characters in the MQ register: 0200 7604 CLA OSR ; Clear AC and OR in switch register 0201 6046 TLS ; Output char and clear transmit flag 0202 6041 TSF ; Skip on TTY flag 0203 5202 JMP 0202 ; Jump back repeat TTY flag test 0204 7521 SWP ; Exchange AC and MQ 0205 7001 IAC ; Increment AC 0206 7521 SWP ; Exchange AC and MQ again 0207 5200 JMP 0200 ; Repeat entire exercise While I'm on the topic of ONMIBUS TTY cards, does the M8650 *require* hardware handshake? -ethan ===== Infinet has been sold.

CP/M-80 drivers for WD33C93 ???

by edick＠idcomm.com

I haven't heard about the bugs, though the device has been pretty much obsolete since WD stopped selling chips and went to making drives instead. If you have drivers for the 5380, I would appreciate a look at them as well. I've never looked at a BIOS using SCSI or SASI, both of which are block-oriented rather than being cyl/hd/sector based. I guess it's time I learned how that works . . .

[OT] They're restarting Chernobyl?

by edick＠idcomm.com

It's just a different outlook, doncha know . . . they're looking at a really cold winter for which they need the power to survive. If they don't survive, it's not going to help them that their grandchildren will have a cleaner planet, since their grandchildren will freeze too. There's this old military addage, that "where you sit determines what you see." It certainly applies here.
