Yes I worked on old computers too. Back in the 1980's even on high-end Sun workstations I used to get up and get some coffee while the C compiler compiled by code. You can't say "It is good enough because things were even worse 40 years ago." Today I am 20 times more productive and can write so

Those T series Thinkpads are great, I was using a T61 until I got a T540 (which is awesome with an SSD), after using the Thinkpads I got a 2nd hand ThinkStation S20. I even got my Mum a ThinkCentre. On 14/12/20 6:39 am, Dr. Nikolaus Klepp wrote: Anno domini 2020 Sun, 13 Dec 11:22:08 -0800 John

I don't call it a problem. With the three board designs, you can make a replacement for one of the "wings". splitting it up makes the design of each really easy. And as said PCBs this size cost under $1 each even in tiny quantity. So what I see you have here is the start of a family of boards.

I designed and built them for what I wanted. Another thing that was on my mind was some one switching from Mach 3 to Machine Kit. The goal was to lay the I\O similar to what you would have with 2 Parallel ports. For the time I used it work, and I still may put it back into use with the little Elk
