As march of progress proceeds, I will soon start release of source code for this project. That will come as a series of releases and phases.
Anyone is interested in using this code to assemble yourself will need to download Zilog Development System from Zilog. This is free and is crap, but it...
Sorry i meant to say THE ones I sold back in the day...NOT.... no ones I sold back in the day.
It is possible I still have one of these. It was to be sold a few years ago when I cleaned things out but I don't remember selling it.
I do remember if you wanted to add 4 drives there was not...
the link you posted is for a 15 meg
pic in this thread is 20 meg.
both use exact same controller (or let say CAN use same controller).
some will say no that 15 meg has a controller 3 times the size. Yes 1st controller was much larger PCB that came with original 5/15 meg. But in time they...
This was sold for model 3/4 at end of model 4 life. I sold 25 of these thru misosys quarterly....so somewhere someone has them
There is a controller that looks just like that sat on top and cables ran between.
Shipped with standard TRSDOS driver.
And used with other tandy computers.
Oh...
More the reason to upgrade to TRS-OS and its guest operating systems TRSDOS 6 and soon to come a newer 24 bit version.
Built to take advantage of eZ80 24 bit addressing and can tear into micropython with power to spare.
Join the millions that have upgraded today...
i worked on a DEC PDP 11/45 in 1983 that had a huge collection of character based porn.
It was inredible how detailed and real it could look just made up by characters...someone spent a lot of time.
There was a Santa with sled and raindeer and when printed on line printer it must have been 6-8...
There are lots of internet articles explaining how IBM BIOS was reverse engineered which broke back of IBM keeping others from building clones.
Once this reverse engineering was done and most importantly, upheld by courts, IBMs hold was over.
Hardware was nothing special and in fact not as good...
news flash..... a merry-go-round isnt a computer either. Maybe add a few parts......
But what IBM thinks is what counts.....they dominate modern data centers and really always have.
But not all things IBM thinks come to be.....they were out smarted on reverse engineering IBM PC.
Russia has...
No its not a toy. In 1981-82 at NAS Kingsville, Fred Haass used a model 1 to help assemble siimulation programs.
We read most of program in using punch cards (100% assembler).
These sims used two Sigma 5 CPUs connected via common memory.
We assembled from punch cards and wrote object out to...
