DEC RX50 using RQDX2 or RQDX3 card will get yo floppy and mfm hard disk, That DIlog or the DSD card may support disks as well. PDP-11/23B is basic machine you have and that is Q-bus so finding cards for it should be easy as the Microvax-II and later also used the same bus. It was quite popular. Check PUPS PDP-11 unix preservation socity for software.

How to clone an IDE drive (OT)

by Glenatacme＠aol.com

Go to: http://www.maxtor.com/Maxtorhome.htm and download MaxBlast Plus. This is a 1.4 MB file, and it is FREE. Be sure to read the directions on the download page. This utility will create a bootable MaxBlast disk which will work under any version of DOS or Windows. Install your drive. Boot from your newly-created MaxBlast disk. Follow the simple directions. You may choose to simply partition and format your new disk, or you may clone an existing disk. We use this every day in our shop when we set up a new drive or upgrade a customer's existing drive. It's simple, easy, and fast. If there is a gross hardware problem with the motherboard or drives, it will fail. Also, if the data to be cloned is garbage, the program may bomb. Otherwise, MaxBlast has a lot of advantages: * Will clone or partition/format any brand of drive. The utilities shipped with Seagate or WD drives sometimes only work with Seagate or WD drives. * FAST partition/format. Where the DOS utilities can take 10+ minutes, MaxBlast works in seconds. * Removes junk. If the drive you are trying to set up has previously had a bootlock installed, or EZ-BIOS, or if any other program is embedded in the master boot record, MaxBlast will delete it without hassle. I use this all the time when I want to wipe a drive and it's data is so scrambled that even the volume name is trash. Under DOS, you are required to enter the vol name in order to delete a partition, which may not be possible if the vol name has been corrupted and now consists of unprintable characters. MaxBlast has no such requirement. If this isn't clear contact me off list. Good luck! Glen Goodwin 0/0

DSL Rate

by kyrrin＠bluefeathertech.com

I just figured out that someone asked me how much I was paying for my DSL >from Qwest. Forgive me, but I can't find who the original poster was. Anyway: Base rate for the line is $29.95/mo. Round to $30. Add to that $35/mo for Qwest.net (the ISP) to be the host. Includes web space (which I no longer use) and mailboxes (which I won't be using much longer). Finally, tack on $15/mo for a private block of eight static IP's. Three are reserved to be the network, gateway, and broadcast addresses for my subnet (I'm subnetted off a class A block), and five are user-definable, function-wise. Subtract one more for the router interface, and that leaves me four usable. Total: A little under $80/month for everything, and that includes a guaranteed data rate of 256K down (I get 384 during rainy weather, and 512K during dry), and 272K up. If anyone knows of another ISP that can give me my own subnet for $50/month or less, and equivalent bandwidth, please say so. ;-) Hope that helps. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com // E-mail: kyrrin(a)bluefeathertech.com Amateur Radio: WD6EOS since Dec.

OT: Firewall running OpenBSD, why?

by yoda＠isr.ist.utl.pt

I became very curious after I read a couple of posts assuming OpenBSD as the best OS for a firewall box. Could anyone explain (or at least point out links) why OpenBSD would be more appropriate for a firewall? I am planning the instalation of a firewall, and I was thinking about a linux box, possibly running the LRP package. I do not intend to raise any OS-war, but rather to understand the arguments for each side.

OT: help...

by ajp166＠bellatlantic.net

Need any suggestions on repair of a PC monitor (SVGA). It's a Dell and was working though it had a long warmup to full intensity. Anyhow I turned it off and now it just chirps when I turn it on. Before I bin it I'd like to see if its fixable... Ideas? I generally dont do monitors and TVs because of the HV, dust and abundance of sharp edges. Allison

I have a one, designed by Charles (?) Cook, and first implemented by John Molnar, which I've reimplemented for the Sol, some Z-80-based machines, and the 8051 embedded systems I've developed. But I never got around to porting it to DOS... Our Dell servers shipped with a program called "Dell Diagnostics" which includes a comprehensive memory test that can check for stuck bits, shorts between address bits, short between address and data bits, etc. It complains when I run it on non-Dell equipment, but usually works, and it's so far caught problems nothing else would catch. hth, -dq

It will take up to a 486-133 CPU, and it will run on one piece of FPM or EDO memory, so, unlike Pentium boards, you can test a single piece. Additionally the boot box indicates whether the memory is fast page or EDO. I've never found a bullet-proof program for testing SIMMs under DOS or windows, so I keep a hard drive loaded up with Win95. If the system boots and I can run defrag (it being memory-intensive) then I assume the SIMM is okay barring any heat-related problems which may only show up after the SIMM gets hot. Anybody know of one? For 72-pin parity memory get an old Pentium board which requires the ninth bit. I got mine from hitechcafe.com. The board cost $10 and a P-60 CPU was $5. (Sorry, no onboard i/o or PCI bus). ECC? Good luck ;>) Glen Goodwin 0/0

PDP-11/23 Cpu

by SPEDRAJA＠mail.ono.es

Hello to all. I'd like to know what kind of expansion or options could be attached to this machines: PDP-11/23 ---------- * KDF11-B 5014313C M8189/DIGITAL * Q-BusMosMemory 5014500C M8067/DIGITAL * DQ614S153040 Rev F/DILOG * System Interface 11/03/ESI * 808836-05 Rev K/Datasystems Design There are 4 free slots. The system was fully functional in an ESI lasertrimmer system for hybrid circuits that was taken out of service 1 year ago. By the moment I have no disk for it (maybe in a future). I'd like to know if could be possible to put some class of disk or diskette unit, even tape, eventually different of DEC stuff. I suppose than this could be possible by some SCSI card, but my experience with this is limited to the use of emulators like Bob Supnik's or E-11. Thanks for all. Best Regards. Sergio

Does anyone have any PCM-12 (pdp-8 clone) hardware?

by xds_sigma7＠hotmail.com

It was an Intercept jr., according to the auction.. Had 3 or 4 plug in cards with it too.. Still not as cool as the PPS-4 development system that was on Ebay a few weeks ago... _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com

TQK70 Jumpers

by kyrrin＠bluefeathertech.com

I already asked this on port-VAX, figured I'll try here, too. Can anyone provide one of the following: 1). Confirmation or denial that the address jumpers on the TQK50 (M7546) and the TQK70 (M7559) are laid out in the same pattern, bit-wise? In other words, does each board share the same pattern for setting its address? 2). A jumper chart for the TQK70, or jumper setting info to set it to the primary tape device address. Thanks much. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com // E-mail: kyrrin(a)bluefeathertech.com Amateur Radio: WD6EOS since Dec.
