http://bitsavers.org/pdf/ibm/series1 you're welcome.. and if you don't already know what it is, you don't want one.

Care to elaborate any on those choices?

Have checked all the diodes and also the caps on the secondary. All works fine and are within specified values. Also checked the diodes on the...

I'm interested in learning more about this system. Pictures and more details would help.

Z380, CPLD, bus extension / expansion. (my 2c)

Well, there are a number of T 1 3/4-base lamps, but they seem to be 28V, not 24. Probably not a big thing, but you can get them here. Surplus...

Nope, again, wildly different artifact colors can happen in any mode where NTSC burst is enabled. It's true that 640x200 is the only BIOS mode that...

I'll just say that I had to fudge a lot in order to get it working on my simulator, I was doctoring the HDD image manually. Not so easy to do on real...

I can't answer that question though. Is there a -9V generator on the board? Presumably you can follow the -9V pin(s) from the EPROM to where it...

Excellent work Tom. Dave

That is exactly what I ran into and had to fix it after to make it boot, but it does work. We may have another source shortly though to crack this...

Another issue: The front panel indicator lights (two green one red) are Taiko K-16 S0 manufacture. The lamp, nominally 24VDC, is an unusual "grain...

I got one in the 2000 at a garage sale 5 bucks and only last year got around to it. Also on lousy computers if someone likes it nothing lousy...

There were other vendors and IBM got nasty about servicing the office typewriters that were beat to hell by using them as computer printers. The...

The structural foam was great stuff. I remember being shown around the place where ours were made. Our tour guide took a paper cup and filled it...

I'm not sure it is that simple. The k10u-rld disk does not have PUTSYS and PUTOVL, The k10hald* disks do not seem have MASMENU. There are other...

So I went through my stack of Five 6100's to make 2 complete systems. I already sold one, and am keeping the other for myself. I do have some left...

Back in the 80's I had a buddy get his amateur radio license. I was into computers, he radios. Had I known we could have communicated via radio or...

Reenignes answer seemed pretty clear to me. Another way to look at it is to compare the output from a composite signal and RGB signal. For all the...

Oh! I forgot to mention... I had to move the memory location of my XTIDE from $D000 to $CE00, then it started working. (Mine only has the 8K EEPROM)

Here are a few pictures from my setup (which, essentially, is a CompuPro ZPU setup). Works great. Just curious if you considered cooling at all....

It appears someone deleted my post because it had my phone number in it :face palm: I am interested in a series/1 for a long time, contact me.

TJ, You can use cpmtools (or cpmtools built with libdsk) to access the Files and get directory listings. $ TD02IMD K10U-RLD.TD0 > K10U-RLD.TXT...

And someone else similarly equipped to communicate with...

So you're 'D without the software package(s)?
