[M100] books in 2022

I'm working on building my library on books and docs related to the TRS-80 Model 100. I have read over the last couple of days, the owner's manual, quick start guide, and basic lab books. Next up are Oppedahl and Enders. What are y'all's favorites related to programming the machine? If it's in

A BASIC operating environment doesn't really meet the definition of "operating system". But maybe I am being too pedantic. It wouldn't be the first time. On 9/29/2022 2:29 PM, Peter Vollan wrote: Huh? The Model 100 says "Copyr. 1983 Microsoft" when you go into basic. It is common knowledge

Not to mention, since no one has, the T600 that was not "compatible" with anything. Though it was an 80c88 with MS "DOS" & Works. Multiplan & BASIC were avalable in ROM. Then came the M2000 (i80186) and the IBM/Tandy era began. I would've liked to see Deskmate for the MT and how that might have

I once had a 16. It actually had a Z80 and a 68000. It could boot Model II TRSDOS, CPM-80, Xenix or TRSDOS-16. The Z80 was used as an I/O processor when running a 68k operating system. The Model II could even be upgraded with a 68000 processor. (And now we return to discussing Model T computers).

But still mostly a brand… the basis for the 80 was the Z80 in their early stuff, but like the Model 16 had a 68k in it. Plus even tho the II had a Z80 like the I, III & IV, I thought operationally it was substantially different and none of the I/III/IV stuff would work on it? (never used

Just to fix a small error, the trs80 Model 100 is 8085 based. Doug On Thu, 29 Sept 2022, 10:13 pm Stephen Adolph, wrote: > And to add to the confusion, there are 2 M100 in the world that actually > do use a Z80! > > On Thursday, September 29, 2022, Justin Poirier > wrote: > >> TRS-80 starts

TRS-80 starts for "Tandy Radio Shack" and "Z80 microprocessor." The M100/T102/T200 have an Intel 80C51 microcontroller, not a Zilog Z80, like the Model I, II, III, IV had, and even worse the TRS-80 Color Computers have a Motorola 6809, so even in themselves, they were not consistent in sticking to
