Hi It seems like I remember doing something like "copy COM1: FileName" or something. It seems like I remember there being an issue with the file name extention. I recall using something other than .EXE and then changing it to .EXE with RENAME. It has been some time but it was something like that.

Another TRS-80 Model 4 sighting

by vcf＠siconic.com

This time it was in the movie Napolean Dynamite. Appropriately enough, it was when he's in the thrift store looking at crap just before finding the D-Kwon dance tape. It's in the lower right-hand part of the screen (when he finds the sai), with half of it being off-screen in the TV edited version (if you have a cinema TV I'm sure you can see the whole thing) but you can still tell it's a TRS-80 M4 if you know what you're looking at. This movie is a must see for anyone that loves off-the-wall comedies and either was or had a friend growing up that was a complete dork. Ebert gave it a thumbs down. Either he took the movie personally or he just didn't get it. The movie is hilarious. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

HP 5036A Microprocessor Lab

by mokuba＠gmail.com

I recently acquired one of these units and am in the process of searching for manuals or any info AT ALL on this unit! So far I've figured out how to call up addresses, store data and program it (havn't really done much since I can't figure out more then how to play with the registers, the output hardware is alien to me :/) I'd love to get a copy of the rom as it was written in the manual, comments and all. Also, if anyone has a manual and wants it scanned, I'll be more then happy to do that for you! And I'm especially keen to know how to manipulate the speaker and output LEDs

Reviving old hard drives

by Watzman＠neo.rr.com

Yes, there is something that can sometimes be done in cases like this (hard drive won't spin up). SOMETIMES, the problem is that the lubricant used on the platter surface has, over time, effectively "glued" the heads to the platter, a problem called "stiction". SOMETIMES, when this has happened, you can "break the platters free" and get the drive to work again. Two things to note, not all instances of "not spinning up" are caused by this, and sometimes the adhesion is so strong that the heads will rip off of their positioning arms before they will let go of the platters. But, in any case, there is nothing to be lost by trying. The procedure is to hold the drive in your hand and give your hand (wrist) a sharp, impulsive "snap spin" centered around the axis of the platter. Sometimes, if this doesn't work with the drive powered off, it will work if the drive is powered up while doing this. The point here is to use rotational inertia to break the "bond" of the head to the platter. One other note, some early Seagate drives (esp. ST-225, 238 and 251 series) are VERY sensitive to the voltage on the 12 volt rail, and the drive won't work (either the spindle or the servo system won't work) if the +12 volt supply is even one-quarter volt low.

Trying to get running an LSI 11/23

by vcf＠siconic.com

I've been tinkering with this mutt LSI 11/23 system I've got and am trying to get it running. It's a custom-built system that has a mix of DEC and third-party boards. It's configured as follows--my apologies if I'm not conforming to standard DEC notation here [notes in brackets]: Cage 1 Slot 1: DEC M8186 | CAMINTONN 504 [1] Slot 2: Dataram Diceon [2] Slot 3: Data Systems Design A4432-4 | Grant Continuity [3] Slot 4: Emulex TU0110401 [4] Cage 2 Slot 1: Emulex Tu1110406 [5] Slot 2: Grant Continuity | Digital Pathways TCU-50DYR [6] Slot 3: MDB DLV-11J | DEC M9400 [7] Slot 4: Empty [8] Notes: 1. I believe the Camintonn card is memory 2. This has "RK:" written on the handle...an RK05 disk controller? 3. The Data Systems Design card has "DY:" written on the handle. 4. Tape controller; is connected by 25-conductor ribbon cable to adjoining Emulex card. 5. See note 4. 6. A real-time clock 7. The M9400 has "HB BOOT" written on the board. Is this the boot ROM card? 8. Does there need to be a bus terminator here? The DLV-11J is a 4-port serial card. Thanks to those who provided the documentation to get it wired. I think I have it correct. I've jumpered pin 3 to the RxD line and Pin 8 to the TxD line on my RS232 port. I've also jumpered pin 4 to ground as directed. The system powers up. There are +5V and +12V LEDs on the front of the panel that come on, and I've checked these lines at the power supply and they are good. One oddity: the terminal marked -12V is a perfect -0.00 on my volt meter. WTF? Anyway, how can I tell if anything is happening inside this thing? I can hit the BOOT switch and the RUN light goes on. There's a RUN switch with a momentary HALT position and an ENABLE position. I can hit the HALT switch and the RUN light goes off. I put the switch back in the ENABLE position and then hit the BOOT switch and the RUN light goes back on. I see nothing on my terminal (a PC running Procomm Plus in DOS so I have real serial ports instead of the bullshit that Win98 tries to pawn off as serial ports). I eventually want to boot RT-11 off floppies on this system. I guess I'll need a disk controller at some point. I'm completely lame. This is the first DEC system I've seriously tried to get running so I'm starting from -1 here.

DEC 3000 PMAG-E dead and gone?

by pete＠tholian.demon.co.uk

I'm in the process of sorting out a DEC 3000/600 i acquired last year. However, the PMAG-E turbochannel framebuffer is sick, for example, if I run tests from the >>> prompt I get this (some detail removed for brevity): t 1/vdacsig ?TFL: 1/vdacsig [PMAG-DA] (+2+ Pxl[#0]=555555, R[668bd3]=978bd3, ? G[603023]=3a3023, B[2f0af5]=880af5, vsimm=1?) ERR-MIPS - ROM OBJECT 'cnsltest' REPORTED A SEVERE ERROR and t 1/shade ?TFL: 1/shade [PMAG-DA] (+3+ tri smth shd err, indx= 0, stamp= 0) ERR-MIPS - ROM OBJECT 'pst-q' REPORTED A SEVERE ERROR Alas what I don't have right now is a DEC 3w3 cable so I can't see what the card is doing (if anything). Is there any hope here or has the magic smoke long since departed? Cheers, Pete -- Pete Edwards "Prediction is very difficult, especially if it's about the future" - Niels Bohr

Cleaning motherboards...

by KParker＠workcover.com

I'm interested in the same issue too - I've got a TRS80 Model 16B that was living in an unused bakehouse for a few years - I think it's a box of dust with some circuit boards in there somewhere :-) I heard a substance you can use that is non conductive and leaves a protective film on the board after - I think its CRC 626 or CRC 262 or similar - someone on the list might know a bit more. ++++++++++ Kevin Parker Web Services Manager WorkCover Corporation p: 08 8233 2548 m: 0418 806 166 e: kparker(a)workcover.com w: www.workcover.com ++++++++++ -----Original Message----- From: cctech-bounces(a)classiccmp.org [mailto:cctech-bounces@classiccmp.org] On Behalf Of Gavin Thomas Nicol Sent: Saturday, 1 January 2005 3:37 AM To: General Discussion: On-Topic and Off-Topic Posts Subject: Cleaning motherboards...

Anyone have a Seagate ST01 or 2 ?

by aek＠spies.com

>from Fred van Kempen Al, Can you ask the list, or anyone, if anyone has an old Seagate ST01 and/or ST02 controller available? I cant post to the list from my biz address.. -- I think these were PC scsi cards.

You can't, in MS-DOS. COPY uses ASCII transfers for COM ports and complains if you try to force binary, because it needs to see a ctrl-Z to know where the end-of-file is. -- Pete Peter Turnbull Network Manager University of York
