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

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

LINCtape images

by cc＠informatik.uni-stuttgart.de

Short question: How do I transfer LINCtape images back to tape on a PDP-12? Ideally there is some binary program to load via papertape to format a tape and recreate it with data transfer over the console serial line. Christian

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
