Tandy when the other way and turned a computer into a terminal.
Jon, Many of those large plastic CRT and computer plastic cases were injection molded (USA spelling) with plastic that included a foaming agent to reduce the weight. The molding ends up with a hard...
I found a reference to a "foreign" disk format reading program for the QX-10 that allowed the QX to read other 5.25" computer formats. Program is/was called "Uniform". Does anyone know of a copy...
I have a Quest Super Elf with a S-100 expansion board and a Netronics (I think that's correct) 64K dynamic RAM board that used a Z80 for refresh etc. I'd have to dig out the system to be 100% sure of...

I found a old QX-10 support website on The Wayback Machine that seems to have gone away in 2015. Details on the keyboard and monitor are there: ...
Got'cha. I don't recall what I paid for my QX-16 (maybe $200-$250), but I got it back when there were quite a few QX-10's on the market and 3 or 4 QX-16's too. But it took some time to find the...
Jon,
I guess the SB is one weird system and I know oh so little about it. Sounds like each computer needed hand tweaking since resistors and cap's have such large tolerances. I hope you figure out...
Gordon, I forgot, what exactly are you missing to have a working system? Was any of the missing items promised in the auction?
Yes, I was diagnosed with this condition when I first went to school at age 5 or 6 and wore a patch for a couple of years. Didn't do much good and now in my 70's I still have a "good eye" plus a "bad...
Per Herb Johnson's website the Tandon 100-2 is a 40 track drive. https://www.retrotechnology.com/herbs_stuff/tandon_TM100.html
I contacted a company that sells keyboard foam replacement kits for Keytronic keyboards in the hopes of receiving a single foam piece to see if it will work in the Q601A keyboards too. If so, then a...
Gordon & Robert,
I ran into a major problem (for now) my keyboard has about a 1/3 of the keys not working. I pulled it apart hoping Epson used mechanical keys, but no they when cheap and it is...
Gordon,
I must have 100 laptop bricks floating around here, so I don't need one. I'm not sure what band of voltage(+/- X) is to not going to damage the monitor. Remember the QX-10 supplied +12VDC...
Success!
I got some time to mess with powering up the QX-16 with the video cable running to the monitor. Turned on the QX and my bench power supply and noticed the monitor was now drawing about...
Progress update. I took a closer look at the suspect cap's in my monitor and realized that the tops were domed from epoxy and not due to bulging. So time to move on and see if I could get power to it...
Glad to help out. OBTW, I found those lists some time ago when trying to figure out why a 256K RAM board won't play nice with my otherwise operating Delta Products S-100 system. DP used a couple of...
Here's a good old Epson QX10/16 thread posted in a google group: https://groups.google.com/g/comp.os.cpm/c/p2bBENe_ow0
Plus difference between QX-16 & QX-16HD (hard drive version): ...

Adding more to put everything in one thread.
QX-10 video is 80 x 25 lines plus in graphics mode is 640 x 400. Horz. frequency = ?, Vert frequency = ?
IBM MDA = 720 x 348 and the Hort. freq. =...
Thanks for the info.
Plus I'm adding the following to my last post. I guess the QX video is somewhat like the IBM PC MDA video, but is the lacking intensity signal.
Okay, I dug out my Q702A Green CRT monitor and read the labels on the back. It states it is for use with Q701, Q801 or Q916 A,B or C models. A second label says it needs 12V @ 1.5 amps. So a 50 watt...
I guess I'll dig out my system and rig up a power supply to my QX-10 monitor and see what happens. Worst case I've wasted a few hours and have no results.
One other thought that I've been kicking...
