I got a Apple cube here as part of a larger haul, at some point someone placed a bit of tape on the clear polycarbonate case, the tape is long gone but the yellow glue remains. Am unsure about the hardness of it, if I could use sugar cubes to rub it off, anyone knows a scratch free way to get it off ? Regards -- Jacob Dahl Pind | telefisk.org | fidonet 2:230/38.8

HP 2000 TSB and FORTRAN

by nospam212-cctalk＠yahoo.com

Like many, I used an HP 2000 TSB system in high school to first learn about programming. Wanting to learn more than just BASIC, I soon discovered there was a program on the system that let you write and run FORTRAN programs. All these years later I can't remember anything more than that and haven't seen anything more on it since then until recently. While clearing out my storage space I came across an old binder with a photocopy of a manual. Looking though it I soon realized it was from my high school computer class and described the system for running FORTRAN. So now I have a name at least and a copy of a manual, but haven't yet found anything more and hope that someone here might be able to shine some light and supply more about it. The manual says it was known as OSMI 2000 FORTRAN and was a "series of programs written in the BASIC language which run short FORTRAN programs" on an HP 2000 BASIC system. Anyone heard of this before? Thanks. David Williams www.trailingedge.com

Last week, Ken Gielow passed away. He was the author of the Z80DIS disassembler, which was both interactive and used a form of "artificial intelligence" to cleverly disassemble Z80 code.

I-4004

by c.murray.mccullough＠gmail.com

Did the 4004 chip start our interest in microcomputing? It is 50 today. Classic computing begins earlier but for the masses, if they could be called that in the early seventies, this was it. I hesitate in calling it the first microprocessor as pc'ers will object. Happy computing all. Murray ?

Does anybody have documentation or know about the OKI IF800/300 a.k.a. Sumicom System 830

by pleasefixmybrick＠gmail.com

? It certainly didn't have market penetration in USA! I did once have, and implemented in XenoCopy, a sample disk from an Okidata if800 model 20, which seemed to be the same as a BMC if800 model 20 (if one more alternate name might help you find information). I hadn't heard the Sumicom badging. ? I also had a disk for Oki (don't know if same model) with the Microsoft Stand-Alone BASIC, instead of CP/M. ? Unfortunately, the model 20 was a different architecture all together. I have begun looking into Japanese museums. Maybe there is more documentation and data in its country of origin.

Old Xerox stuff? 820, 860

by Anders.Gustafsson＠pedago.fi

We were cleaning the basement yesterday and I came across some Xerox stuff from the 1980's. For the 860 there are program listings and disk format documentation. For the 820 I have BIOS listings and service manuals for the monitor they used. Ny company happened to work with RX here in Finland and I wrote routines to convert from X860 to WordPerfect. Also from the typewriters. -- Med v?nlig h?lsning Anders Gustafsson, ingenj?r anders.gustafsson at pedago.fi | Support +358 18 12060 | Direkt +358 9 315 45 121 | Mobil +358 40506 7099 Pedago interaktiv ab, Nygatan 7 B , AX-22100 MARIEHAMN, ?LAND, FINLAND

Electronika MC 0511

by technoid6502＠gmail.com

I just received my UKNC from what was Czechoslovakia. Made in 1990 it was dirty but otherwise in good shape. I need to install an alternate power supply as the Soviet one requires 220volts and has a wierd plug. Anyone know where one can find a disk interface for this machine? I have such for several other vintage systems, which use CF cards, as with my Atari 8-bits and Atari ST. I gather there was a floppyface for the thing but that it is pretty rare. Any help would be appreciated. RSX11 awaits this micro-PDP compatible. Best, Jeff

Overclocked TI Silent 703 at 1200 bauds?

by charlesmorris800＠centurytel.net

Please excuse the hijack: I have two Silent 700's, I think the 745 models with acoustic coupler and 110/300 baud rocker switch. One I have fixed and it works great (well, at least as far as that silvery thermal printout goes). Unfortunately one has three bad keys and at least one missing column on the printhead (yes, the head itself is bad). Does anyone have a junker >from which I can buy three keyswitches and a printhead? :) thanks Charles

Overclocked TI Silent 703 at 1200 bauds?

by curiousmarc3＠gmail.com

I recently acquired a TI Silent 703 on ePay and just fired up. It worked right away. But I expected it to work at 300 bauds as advertised, and to my surprise, it clocked at a the head turning speed of 1200 bauds! Did they hot-rod it later in its product life? It says MODEL 703 at the back, part no. 2310503-0010. I did not open it up yet. Is this a hardware mod? Is there an internal switch that can toggle it between 300 and 1200? Marc

TI-99/4a Monitor power cord

by nospam212-cctalk＠yahoo.com

I have a TI monitor that has a power cord that is becoming sticky and gummy and I'm looking at what to do with it. I figure the best solution is to probably see about replacing it with a new one. Has anyone ever looked at this monitor and the cord connection? Have any info on it? How difficult it might be to replace it? I haven't been able to find any doc or anything searching online but may just not be using the right keywords. Any other suggestions on dealing with the cord besides replacing it? Wrap it in something I suppose... Thanks in advance. David Williams www.trailingedge.com (http://www.trailingedge.com)

memory assignment jumpers MM8EJ

by billdegnan＠gmail.com

I am unable to confirm for sure the memory assignment process for I know without a doubt how to set their page assignments. I can guess but that's dangerous and inefficient. I want to test an unknown core stack, so I need to know which RAM space I am testing. I have a PDP 8e core stack with the following: H121 8x12 core G233E G111C Anyone know the process of assigning the RAM space on the boards? Bill

Zorba owners/Help diagnosing display issues

by ben＠listenfaster.com

Hello from Seattle everyone, I'm new to the list. I recently bought a Zorba on Ebay, which was my first machine as a kid back in 1985, dialing into BBSs and learning assembly and basic. I put a lot of hours in on this machine and was very excited to acquire one, even though the sale was 'as is'. I have some issues to address, beginning with perhaps a faulty component on the video board driving the crt. While I'm an experienced programmer and have some rudimentary skills with electronics, I'm going to be in bootcamp troubleshooting this board. I have some help in my network of friends, but wanted to throw this out to the list. Are there any Zorba owners who would be willing to trade notes/advice with me on their experiences troubleshooting hardware issues (or anyone else out there, for that matter :) )? Have you used the composite video out to feed another monitor? Detail on my first issue: the display appears to need the kind of stabilization I _thought_ the horizontal and vertical hold adjustments would provide, but it's not entirely stable. I have tried the composite out, feeding it to a cheap composite->HDMI adapter, but that signal looks like a blank screen in need of vert/horiz hold adjusting. Before I go much further, I was hoping someone out there might be able to verify their use of the composite out to an external display. I haven't found any detail on what that signal should look like, other than it's 'composite' - maybe someone with more expertise can tell me what assumptions I can make about a composite signal. Thanks for reading that long message - and glad to be a new member of the list. Ben

SQ703/6 conversion and a little fun

by g4ajq1＠gmail.com

A few months ago, thanks to help from several people here, I converted an SQ703 TMSCP controller to SQ706 MSCP. I had problems trying to use it on the vax due to the complexity of mapping Q-Bus registers under ODT, so put off trying until I got the LSI-11/73 going. Now I have a problem: It seems to run and recognise the controller as SQ706 according to the on-board diagnostics, however it insists saying it is at 777450, the TMSCP address.? Trying to change it gives me an out-of-bounds message. OK, I thought, I will just use it there. Put it in to a running RT11 system and it shows up at 772150 and clashes with an existing controller! It seems that one of the PALs is maybe setting up the address! Anybody else tried this? cheers, Nigel Here's the fun:? https://www(dot)bbc(dot)com/news/entertainment-arts-59089596 Maybe our vax computers will become popular once again! -- Nigel Johnson, MSc., MIEEE, MCSE VE3ID/G4AJQ/VA3MCU Amateur Radio, the origin of the open-source concept!
