WTB/T Grid SCSI pod

by lgwalker＠mts.net

I have a Grid laptop 5 1/4" SCSI floppy drive (mfgd 1982) for my m.1520. The 15xx 's used some peripherals (eg. VGA, AC power, SCCI) via adaptors they called "Pods" in the battery ( which was also a Pod) slot. The SCCI connector is a DB50 which was also found on some DEC, SUN,etc. peripherals TMK. Anyone on the list have this Pod or for that matter any Grid Pods or accessories they'd part with ? Lawrence lgwalker(a)mts.net bigwalk_ca(a)yahoo.com

DEC3000/400 - D/UX3.2 & VT420

by DAW＠yalepress3.unipress.yale.edu

Is it possible to run a VT420 on my DEC 3000/400 (running Digital UNIX 3.2) while also having the PMAGB-B graphics console? IIRC, I cannot use serial port 1, since the I'm using the graphics console... I have the VT420 (9600,8,N,1) hooked to the printer port, using a DEC H8575-A REV B MMJ adaptor. All I got was a ~ (tilde) when I started it up. I also have a H8571-E, and a H8571-F adaptors. Should I be using ones of those instead, with a gender changer? -- --- David A Woyciesjes --- C & IS Support Specialist --- Yale University Press --- (203) 432-0953 --- ICQ # - 905818

reviving a HP 9000/310

by glenslick＠hotmail.com

Can you stop the boot process when it is searching for a boot device and then manually select the boot device and add the ISL option? If you can get to an ISL prompt then you should be able to boot in single user mode. I have no idea if older HP 9000 systems have an ISL prompt, my experience is limited to 9000/700 series systems. >From: "Rumi Szabolcs" <rumi_ml(a)rtfm.hu> >Reply-To: cctalk(a)classiccmp.org >To: cctalk(a)classiccmp.org >Subject: reviving a HP 9000/310 >Date: Tue, 27 Aug 2002 01:53:48 +0100 > >Hello! > >I'm currently trying to make an old HP 9000/310 machine work. >Some information about the machine and the status of the >"project" can be found out at: > >http://paranoia.rulez.org/~rumi/hp310.html > >What I currently need is either a way to crack into the >HP-UX that is already installed on the box, or a floppy >set (== images which can be written to floppies) of HP-UX >that would run on this machine which sports a Motorola >68010/10MHz CPU, 2MB RAM, and a HP9153C 40MB HP-IB hard >disk drive / 3.5" floppy drive combo. > >If you have such floppy images, or could help me with any >software, documentation, or information regarding this system, >please don't hesitate to contact me via email. > >If I succeed, I'm planning to put a nice webpage together >about the system, with pics, history, infos, etc. > >Thanks, > >Szabolcs Rumi > >- _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com

Conclusion: Commodore 64 *is* lame!

Maybe it's because I still don't have the right cable. Whatever. >This is a nightmare. The rear connectors on that monitor are Y/C connectors, not Color Composite. So unless the cable is dumping out a Y/C signal, it might not work there (although, IIRC, you should still get a B&W image when plugged into one of the two channels... so maybe the rear inputs on that monitor are broken?) I also recall a switch back there for something. I can't verify as I sent my 1702 to Toth along with a complete C64 system (which I have regretted ever since, as it was a very complete system... but I suppose with him it has a better home where it is really being used, as compared to me where it probably would have sat in a box for the rest of time) -chris <http://www.mythtech.net>

After doing a web search, I found a listing for the keyboard routine. http://www.classiccmp.org/mail-archive/classiccmp/1998-04/0779.html It appears that you enter an 3 digit octal number and then hit a function key.

G - Loads the program counter with the contents of HL I dug out my copy of "the 8080a Bugbook", but it does not discuss the operation of the keyboard.

BACK-OT: which CP/M machine is best (to copy)? :)

by doug_jackson＠citadel.com.au

I vividly remember my Pulsar Electronics Little-Big-Board. It was an STD bus board, sporting a 4Mhz Z-80, 64K ram, 8" floppy disk interface (1.2Mb!!!), RTC, and dual serial ports. The board came with a full BIOS listing, as well as the device specific CP/M stuff. I remember that you could re-link the CP/M innards to allow HDD support (I was never *that* rich). Spent *many* hours on that box, running Wordstar, and a cool pascal compiler called Turbo Pascal. I used a terminal that I brought from the US (ZRT-80). I still have it, in a 19" box, with dual M4854 (5.25" 77 Track) drives. (Boy, it was hard to find the HD media then). The box had the bigest storage on the block, and I was the envy of all my friends when it came out. A mate had an kaypro system that supported dual 170K? disks. (grin) From memory, the board cost about $500 Aus, each drive cost about $450 Aus, and the Apple II power supply for the case cost about $35US from Jameco. All in 1985 currency. Anyway, back onto topic. I still have all of the listings, and the full schematics for the box as well.

UnixPC 7300 --> 3b2

by MichaelDavidson＠pacbell.net

FWIW the UnixPC 7300 which was belatedly adopted into the 3B family, and renamed "3B1" by the marketing guys, despite having nothing in common with the other 3B machines, was actually a close cousin of the CT Miniframe. (I'm not sure if Convergent actually manufacured the 7300, but it was certainly their design)

MMD-1 / Mini-Micro Designer programming

by karl＠jagegud.com

Hello. I just subscribed to this list because I got my hands on an MMD-1. My teacher in digital tech was going to throw it away but I managed to stop him. He had already gotten rid of the instruction book. My problem is that I've never programmed anything like this before, and I'm having a hard time understanding anything of it. I have read a few threads in this list about the MMD-1, but they didn't help much. Let's say I want to put a number in one of the ports, how do I do that? address data mnemonic comment ------- ----------- -------- -------------------------------------- 004 000 076 123 MVI A<-123 ; load 123 into A 004 002 323 000 OUT 0 ; write it to port 0 004 004 166 HALT (code from http://www.cs.unc.edu/~yakowenk/classiccmp/mmd2/programs/setPorts.html, so it's really for the MMD-2 but I think they are quite alike) Now that would put the octal number 123 in port 0, right? How do I enter this into the MMD-1? I've got an octal keypad plus the letters "H,L,G,S,R,A,B,C"... Anyone who knows exactly what they do? /Karl Bernst?l

Shameless Plug Alert

by kyrrin＠bluefeathertech.com

Hi, gang, Well, I'm back. I may not collect computers much any more (my ham radio and test gear interests have flared, big-time), but I still have some decent stuff to get rid of that I think just might find a good home with some of you. I still come across classic stuff in my travels as well, so I think it's worth it to maintain contact. Here are some links to stuff I currently have listed on Ebay. S-100 system owners should take special note of a couple of the items. ;-) DEC Micro-RSTS 2.1, and various PDP diagnostics and formatters on RX50's: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2048901683 MultiBus Extender boards and a MultiBus prototype board: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1761718677 S-100 Bus Extenders and Prototyping Cards, all unused/NOS: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2048953253 Wombat QBus-to-SMD disk controller: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2048984536 S-100 Bus Passive Backplane Cards (six-slotters): http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2048994932 Also: I still have available, for local pickup southeast of Seattle, a MicroVAX 3 (KA650, 32MB RAM) in the BA123 (end table) enclosure, priced at $100.00 or best offer. It includes a Sigma RQD11S SCSI/Qbus host adapter that can work either disk or tape drives, two 760MB SCSI disks, TK50, etc. Last time I fired it up a couple of years ago, it was still booting from the NetBSD load I put on the disks. I don't recall if the Sigma adapter will boot from CD-ROM or not, but I'll throw in an RRD40 and its controller if I can find them. Thanks for putting up with a most shameless plug.

I hate to do this, but.. FA Osborne 1

by nerdware＠ctgonline.org

I didn't want to go ebay, but last time I posted here with surplus stuff and asked for offers, I got no response. However, in case you're interested, I have put my Osborne 1 up on ebay. It's an original beige case unit. Monitor lights up, but can't get it to access the drives to boot, which I understand is a common fault amongst surviving Osbornes. The AC cord cover is intact, it's in good cosmetic condition as well, and includes the original disks in the original disk box. The included disks are: CP/M system CP/M Utilities MS Basic Wordstar (includes keyboard overlay) Supercalc. If you want to see it, it's at http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2047971573 I'll try offering a bunch of Apple II stuff here on the list in a couple of days.... it's time to get out and concentrate on the things I do have time for.

HP gear

by pat＠purdueriots.com

I've just come across an HP 9000/300 and 9000/220 in a dumpster over here at University Salvage. I see that the 300 has a 68010 (first one I've owned), but am not sure about the 220. Both have video and 'keyboard' connections. I've found some 300 info using google, but nothing helpful on the 220. Also, are these worth anything? I've got no drives with them, but I did get a bunch of lab I/O boxes (multimeter, and other things) with them. -- Pat

Conclusion: Commodore 64 *is* lame!

by foo＠siconic.com

Ok, here's how lame the C64 is. I have three of them. I have three different types of video cable. The first thing I notice is that the C64 I've been working on has a different video connector than the other two. The other two are older; the one I've been working on newer (based on serial numbers and internal differences). The one I've been working on is most likely dead. I can't get anything out of it after trying various combinations of cables and monitors. So how come none of you C64 experts piped up to tell me that the video connector on the C64 changed over time? The later one had more pins, and the C64 video cable (that I searched all over for and finally found) only plugs into the newer style connector. It won't plug into the older ones because there are too many pins. Worse, I can't get the video to work if I plug the cable into the back of the 1702. I can only get it to work with the composite connector on the front. Maybe it's because I still don't have the right cable. Whatever. This is a nightmare. See, this is why I have such a poor opinion of the Commodore 64. Sure, technically it's a nice computer. But practically, it's a pile of shit.
