I picked up a used MX-500S on eBay and later a DS1 to go with it. I still need to pick up a compressor some day before I can use the DS1. What I don't have are any manuals nor can I find any online anywhere and it's not clear if Metcal or distributors sell copies of the manuals. It would be nice to have instructions for the DS1 before I need to use it the first time. I don't think I have all of the necessary filters and such. -Glen > > There is only one TRUE soldering iron.

Manual "Practical Microprocessors" HP 5036A Monitor ROM

by glenslick＠hotmail.com

By request, you can currently find source code for the HP 5036A Monitor ROM here: http://home1.gte.net/~gslick/5036a/5036A.HTML This source code was generated by unassembling the 5036A ROM and then adding the comments, labels, and symbols from the source listing in the manual. I have not had time yet to proof read all of the comments that I manually typed into the source from the manual, but I have verified that this source reassebles into binary code that matches the ROM. Appendex E of the manual contains notes on running the demo programs in the ROM {EHCO, ANDGT, CONV, WTM, SQRL, ORGAN, ROCT, STW, SNAKE}. When I have more time I will try to add that info. -Glen

Trouble with ASR33

by vcf＠siconic.com

I'm currently fighting with an ASR33 trying to make it perform a carriage return. Currently, the carriage is stuck all the way on the right side and refuses to budge. I tried to find something inside that would release it but I haven't located the magic tab. I've noticed something else. When I have the punch turned on, the '8' bit doesn't punch. For instance, if I hit "RETURN" I get the 1 + 4 + 128 bits punched, but no 8 (1 + 4 + 8 = 13). I don't see anything obvious, like a level that's come loose for example. I also lost the tab that holds the little plastic cover down over the reader mechanism. In trying to take the main cover off so I could look inside, I didn't notice the two screws on the front until after much wrangling, and just after the tab broke off and either fell or flew into oblivion. Whoever designed the ASR33 must have sold their soul to the devil to make it all work. It's amazing how intricate and delicate everything is, and how damn kludgy as well. I'm impressed, but not. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *

HP9830 keyboard

by ard＠p850ug1.demon.co.uk

I am currently restoring an HP9830. I guess this is a classic computer (for all it says 'calcualtor' on the nameplate) because it runs BASIC, and is 30 years old! Repairing the electronic faults has not been a problem (boards of TTL -- yum...). It now powers up, runs programs, drives the 9866 printer sitting on top of it, saves/loads to cassette, and so on. I am now left with the keyboard which has 5 problems : 1) The 'Stop' keycap is missing, although the switch is complete and undamaged 2) The keycaps need cleaning 3) The power-on lamp on the front of the machine is burnt-out 4) The mains switch is broken 5) The plastic keyboard bezel (surround) was badly broken by the postal 'service'. I have most of the broken bits of plastic OK, solutions ... 1) My junk box supplied a keycap that will fit (without modifications), although it's too short and has the wrong label. It'll do for the moment until I cna find soemthing better (unless anyone here is mad enough to have stripped a 9830 for parts -- I hope not!) 2) Trivial to put right! 3) This is a wire-ended bulb, running off the 5V line through a 22 ohm resistor. I can get a 5V 60mA bulb -- as I don't want it to be particularly bright this should be fine. Does anyone know what the original bulb was, though. 4) This is more of a problem. The original switch is a DPDT rocker (and all 6 terminals are used -- the NC contacts connect to a 1M resistor used to discharge the mains filter when the machine is turned off). It mount with 2 screws onto the keyboard chassis. There is very little space in that area too. I don't want to modify the machine more than I have to, and I can't find a suitable switch in any of the catalogues. HP used the same switch on many devices in the 1970s -- the 9866 printer has an identical switch, so do the I/O expander and disk drives for my 9825. Anybody know of a source (I can provide more details, like dimensions, etc, if anyone thinks they can help)?. If all else fails, I'll replace the switch on one of my 9885 drives (where there's a lot more room) and use the switch removed from that drive in the 9830. 5) Any suggestions as to how to repair this? The plastic will stick with dichloromethane, but of course it's not very strong. I have heard of a technique of soaking a piece of cloth in said solvent and sticking it to the back of the plastic to strengthen it. Anyone ever tried this and have any tips? -tony

SWTPC TV Typewriter II restoration

by glenslick＠hotmail.com

That brings back some memories. The first computer I had back when I was in the 7th grade was a KIM-1 that a friend of my father gave me. Eventually I bought an 8KB RAM expansion board and a SWTP terminal kit so I could run BASIC on the KIM-1. The SWTP terminal kit I had looked about the same as your pictures, except it included a full beige plastic case. The kit must not have been too difficult to put together since I don't remember having any problems getting it built and working. I later managed to blow something up on it once though when I somehow plugged one of the Molex connectors in backwards, but a local computer club member was able to repair the damage for me at the time. After a couple of years I traded the KIM-1 and the SWTP terminal in towards a brand new Apple II+. That's one trade I wish I never made. >Here are some links to my CT-1024 TV Typewriter II pages. >http://www.swtpc.com/mholley/CT_1024/CT1024_Index.htm >http://www.swtpc.com/mholley/CT_1024/Restore/CT1024_Restore.htm _________________________________________________________________ The new MSN 8: advanced junk mail protection and 2 months FREE* http://join.msn.com/?page=features/junkmail

No, it's an H/Z89 was: Re: Z-100 find ?

by WA8MFL＠aol.com

Stumbling across this thread, I couldn't help but notice the problem. One of the first order of business on the '89 is to check the power supply Molex connector on the back of the supply. This has a habit of getting too hot and carbonizing. Bypassing the heavy current lead is the usual way to handle that. You also need to check on the controller board to see if it's set up for hard-sectored disc or softsectored ones. The hard sectored (10 sectors) are probably long gone from this world. I still have mine and it occasionally gets the dust blown away. For those who learned to use a good typewriter this is the best keyboard ever installed on a PC.

Hacking my KTM2 (6507)

by dwightk.elvey＠amd.com

Hi I've been disassembling the code for the KTM2 keyboard. I see now how they generate the various sync signals. The 6507 uses address line A0 to A9. A10 to A12 can be used for various strobes. Jumping to these addresses with different values fro A10 to A12 cause no change in the code executed but effect the video. A8 is used as a ROM select and A9 is used for A8 in the ROM. This way, the code maps into the first two 256 byte blocks of the ROM but the addresses look like 1xxH and 3xxH. They chose 1xxH because they do no subroutines but use the TXS and RTS to execute strings of addresses ( a little like a Forth engine does ). Now, as I've been disassembling the code, I've found some funny looking code. It causes difficulty for my disassembler. Here is a chunk of what I found. It sure looks like someone was on something when they did it. I suspect that it was to adjust the execution times to be equal, regardless of the result but I thought I'd pass it on and someone could explain how it worked. F1E2 03E2 5001 BVC L014 ; 03E5 F1E4 03E4 2A ROL A F1E5 03E5 L014: ; 1 F1E5 03E5 3002 BMI L015 ; 03E9 F1E5 03E7 F0 DB F0 ; note this could have been ; F04C BEQ ... F1E8 03E8 L017: ; 1 F1E8 03E8 4CF00D JMP L021 ; 0DF0 ; You can see that my ; disassembler loses it here F1E9 03E9 L015: ; 1 F1E9 03E9 F00D BEQ L016 ; 03F8 F1EB 03EB 30FB BMI L017 ; 03E8 F1ED 03ED 4CF50D JMP L018 ; 0DF5 Anyway, it is a screwy piece of code?? The addresses at the front of the line are the ROM addresses. The next col is what the 6507 thinks it is addressing. You'll note that I'd dropped any high order bits above A9 since they don't effect flow, only the strobe lines( see L021 above really goes to 1F0H ). Dwight

I looked (mostly) all over for these; never thought to check the company Dave's provided. I actually bought most of the parts to modify a regular handtruck to do this, but haven't got a Round Tuit on that project yet. A bit pricey, the cheapest lift starts at $400, but if you've ever put a Kennedy 9100 four feet up in a rack (on it's slides) by yourself... these might be a good value. The category they're in is a bit counter-intuitive: look for them in "Carts / Casters / Trucks - Lift Trucks - Lift Truck Winch". Of course if you have lots of bux you can get a hydraulic one, but.... Cheers John

I can then rotate, using the fan, to get it to cycle through an action. You still have to manually lock up the clutches or they will drag. You do this by squeezing the two pieces that hang out and catch on the release lever. Once you got them locked up, you can type a key and cycle things one step at a time. Dwight

I have the original manuals but just not here. I'll be getting them this week to help with this. I'll look for that release lever. As for the read cover, it's actually the small tab that holds it down. That broke off at the stem. It was part of a piece of very thin metal that had a spring effect. If you look at the piece of metal that the tab is connected to you'll see what I mean. The only thing I can think of to fix it is to either find a replacement (not very likely), glue a small piece of metal to the springy-thingy so I can affix the tab back onto it, or make a new one. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *
