Followup: Hazeltine "Computer"

by cclist＠sydex.com

Well, I finally got around to prowling through the 5.25" floppy archives for the so-called "Hazeltine" computer diskettes. I found 'em--in the last 10 diskettes in the file(!). In the meantime, I ran across all sorts of names of systems not heard recently, such as "Peoples World" and "Pan Asia". The diskettes contain only the legend "Hazeltine CP/M" and date from about 1982 or so. The bad news is that the boot tracks contain a CP/M system image, along with CBIOS, but no clue is given as to the system name. Looking at the directory, there was a disk utility to format and surface copy, but no identification there either. There was also a copy of Spellguard and Wordstar--aha! Wordstar almost always contains the name of at the least the terminal, if not the system. Well, it does--but the terminal listed is an ADDS Viewpoint--and no system named. :( Bottom line is that I have nothing to contribute to the "Hazeltime Computer" legend--and, with the discovery of the ADDS terminal code, don't even know why the customer insisted on calling it a Hazeltine (but he did--I found the letter in my files. So--shrug! My guess is that the "computer, given the date" may have been housed in the same box as the floppy drives.--and that a Hazeltine terminal was connected to it. But I didn't think that a Hazeltine had cotnrol sequences anything like an ADDS Viewpoint. Cheers, Chuck

TMS340x0 (was: Any early DSP fans?)

by aek＠bitsavers.org

> Does anyone have equipment that utilizes this chip or have an > opportunity to work with them directly? In the PC world, there was the TI TGA card. I've seen them most often in arcade games. Several vendors used them, including a couple of generations of Atari hardware (Hard Drivin', etc.) Apple built an evaluation card for the 340x0 when we were deciding on how to implement accelerated graphics cards. The decision was to use a 29000 processor (the 8*24 GC card).

PDP-11/70 Panel brought back to life

by pdp11＠saccade.com

Well, it took a few years, but I finally brought my PDP-11/70 panel back to life: http://www.saccade.com/writing/projects/PDP11/PDP-11.html I'm afraid I don't have the space or power (or noise tolerance!) to have the real thing around. Has anybody else brought panels back to life? I'm aware of the Spare Time Gizmos / Ersatz-11 work, and of course the incredible "Gallery of Old Iron". Any others? http://www.sparetimegizmos.com/Hardware/KY11_Interface.htm http://www.thegalleryofoldiron.com/ Cheers, jp ps - An open thanks to Tom Uban for sending me the schematics - that was a big help.

I have stuck the raw scans of that section in with the rest at ftp://ftp.pdp8.net/misc/4010/ I will try to clean them up next weekend. I think I found all the files from that section but if not email me and I will find them. Before I forgot about it I was debating on the best way to deal with the foldout pages in that section. The big foldout pages in this manual frequently had two separate drawings. Would people prefer that they be on one big pages like the real manual or on two separate pages so viewing and printing will be easier for people who can't print on the foldout size paper?

Machine Independent Storage Idea...

by zmerch-cctalk＠30below.com

Rumor has it that 9000 VAX may have mentioned these words: >I don't know how much times a flash memory can be written. It might be OK to >make a bootable device from it. Between 10K and 100K times - IIRC, CompactFlash has virtual sector mapping with load-balancing to attempt to reformat the sectors evenly(ish). Dunno about the others... >My concern is about how to make replacement RL02, RD53 or similar. Flash >memory might not be good for this purpose. Depending on how often the machine is used, it may very well last a long time... but if you're still worried: MRAM. The older 5V stuff has writes into the millions, IIRC, and some new 3.3V stuff is listed as "nearly unlimited" - you can interpret that as you wish... ;-) Freescale (read: ustabeen-Moto) didn't list a maximum write life in their datasheet for the 4Mbit part they sell. Not the cheapest, but it's not outside of "affordability" IMHO. Laterz, Roger "Merch" Merchberger -- Roger "Merch" Merchberger | "Profile, don't speculate." SysAdmin, Iceberg Computers | Daniel J.

Originally starting with Amiga's his collection has grown to emmense proportions and currently includes Spectrums, Amstrads, MSX's and loads of other stuff (including books & manuals). His website is: http://www.commodore-amiga-retro.com As to why he isn't on this list himself? I can't answer that. He is aware of this list and of the site. Perhaps it's because he gets too many emails from other lists/groups. I do know he sometimes works long hours and such. Personally I myself can only deal with 100-200 emails a day. Any more than that and old mail gets left until I have got my email account down enough to rediscover old unread mail. He certainly isn't a bad person at all, he has helped me out in the past with amiga software and (colour) photocopying magazine pages for me. He does dislike Microsoft and Windows though.. especially modern Windows OS's which are constantly updating and sending unknown info via the web. However, that's getting off-topic.

Compaq Portable III problem

by aliensrcooluk＠yahoo.co.uk

Hi, Someone I know just got his hands on a Compaq Portable III. Read the 3 emails below, which are in order. Anyone got any ideas what might have gone? Regards, Andrew B aliensrcooluk at yahoo.co.uk Hi Now here is the thing... It gave out a massive electronic bang when I switched it on. Something definitely blew.. But it wasn`t the main computer, cus up popped the orange screen with IBM on it, the hard drive is working, the floppy drive is working as is the keyboard... I can even run the programs on it.. The crack came from by the switch.. Slight burning smell, but gone now. And is working fine. This baby has travelled a long way these two days... I guess not very happy. I can`t get over the build quality.... scuzz ---------------------------------- Interesting this.... [ quote ] Nancy Hackett's bad experience: Oh, did this machine have problems! I went through four of those nifty plasma monitors, several hard drives, two factory rebuilds, and an uncounted number of motherboards trying to track down internal error codes that Compaq said didn't exist! It came (not so) lovingly to be known as "The Compaq from Hell" with the motherboard rumored to be numbered "666". Both the maintenance manager's and the Compaq regional rep's hands would sweat every time I lugged it in. The spectacular finale was when the power supply blew, shooting blue flames 18" out the side! LOL! That was an experience! [ end quote ] Not quite the flames as described... scuzz ------------------------- Andrew > That doesn't sound too good. It may still > work for now, but if something did go then > it's likely to be putting a strain on other > components depending on what went. > It looks cool though ;) Well spotted. The thing just flipped out. All I get now is all the indicator lights to power light, caps lock etc flashing at regular intervals. Hopefully not too dificult to trace and fix, subject to there being no replacement parts involved. As I say the screen was working, so too the drives, keyboard and obviously the processor and memory so I am thinking something to do with the power supply.. I had feared the worst... And did switch it off. But I did just check and she fired up but then just stopped... Never mind. scuzz

That's the story that I got from the Seagate marketing engineer when I complained about new ST-225's occasionally showing this problem. . However, Wikipedia states that the problem really is heat and lubricants: http://en.wikipedia.org/wiki/Stiction So, the moral is "never trust a marketing guy", I guess. Cheers, Chuck -------------------- Reply: Or don't believe everything you read on Wikipedia; in my experience (quite a few Seagate ST-225's and 251's, and recently even a Conner IDE drive) it was always heads sticking to platters when the drive was shut down after running for a long time. But perhaps bearing lube was also a problem (that I just never ran across). mike

Actually, it might be worth checking out USB modems: I think many actually attach as a regular USB serial port that has a modem attached to it - though it's all within a single blob. Not having a USB-to-serial adapter myself I just built myself a dummy phone line (12V battery, 2 caps and a resistor) so my modern stuff (Macs with modems but no serial ports) can talk to my Amiga (and other stuff) via an external modem set to auto-answer. Both on my server (B&W G3 running NetBSD) and my laptop (G4) the modem responds to good old AT commands... This leads me to suspect that the Apple USB modem also will respond to AT commands. The only danger is that it might want firmware to be loaded at attach time from the host to the device (like my %^&!ing MIDI adapter!) Joe.
