I have over 30,000 I personally typed (with one finger) in my attic..And you used punch cards!
I very strongly suspect that you've misremembered that. The 8086/8088 is an Intel chip with a "philosophically" similar architecture to the 8080 (and 8085 and Z80) but not byte compatible. That architecture was completely different from the Motorola architecture of the 680x series that culminated in the 6809.I learned 6809 Machine Code ! I later learned 8088 code, it was backwards Byte wise from MOTO. Both chips where 8 bit sudo 16 bit processors. IIRC the 8086 was a full real 16 bit over the IBM PC using the 8088.
I guess since you wrote your own programs you don’t have to worry about compatibility.Well, that hardware had ASCII built into it. Such as a Chip that contained an ASCII encoder built into its "mask".
So it would take the matrix of a Key board of switches and turn it into ASCII code to feed your processors or other MPUs handling the peripherals.

There's more to a processor's architecture than it's register set, yet that alone shows how radically different the 6809 and 8086 are.

Wow a company would NEVER provide that much documentation for there computer these days!
"Big-Endian" vs. "Little-Endian"Yes, I said the 8088 was "Backwards" from the Moto designs. Also the Low Byte / High Byte vs the High Byte / Low byte stuff if I recall correctly.
OH! My bad. Opposite endedness, of course.Yes, I said the 8088 was "Backwards" from the Moto designs. Also the Low Byte / High Byte vs the High Byte / Low byte stuff if I recall correctly.
That's not the half of it. They actually published the entire schematic. You might be interested in part five of sheet 1. That's the keyboard matrix. The TRS-80 decoded the matrix to produce ASCII(ish) codes in software, as you suggested. An encoder chip takes that burden off of the CPU and frees up some memory address space, but adds a little bit of cost.Wow a company would NEVER provide that much documentation for there computer these days!
Parker Big Red ballpoint. I still have mine.

And DEC made the same mistake with their PRO 300 line, a contemporary of the PC-XT, far superior hardware, very poor choice of OS, little third party software, and as far as I know not a shred of third party hardware. A fast and utter market flop that helped put DEC out of business (one of several factors). But of course, we're up to '83 now.
As a member of the freshman class of '83 at Stevens Institute of Technology, I had one. It was a nice machine, but coulda shoulda been so much better.I remember that and have seen one in person.
They do provide data for the chips, and companies producing the boards will have everything well-documented.Wow a company would NEVER provide that much documentation for there computer these days!
As somebody who spent a decade doing reference designs for Intel consumer PC's, we gave away everything. Sure, you don't get the micro-code, but you could get the schematics and all the board collateral for you to do the HS paths or just copy and paste them. We would build and give away about 10k working units with full design/build collateral to "seed" the ODM's so they can do things like add a USB port and call it their own design.Wow a company would NEVER provide that much documentation for there computer these days!
There was a blizzard in 64 in Detroit too. I was 8. In 78 Detroit must have been hit hard. I don't remember the winter of 78 being bad in Ann Arbor.

It got that hot last summer!100 degrees F / 38 C that day here in southern Virginia.

Wow, I know where I was that day, but no one was making a big deal over the date. I just know where I was in July that year....if you remember where you were and what you did on 7/7/77.
Our local temperature reached 100 degrees F / 38 C that day here in southern Virginia.
