So, this isn't exactly retrocomputing and it looks like it's from four years ago, but I just found it and thought that many here may find it interesting.

This guy built a simple 8-bit CPU out of essentially discrete logic circuits (from what I've see so far, nothing more complex than a 4-bit adder chip) and explained the entire process.

I was definitely a Commodore kid, and BASIC was my first language. Maybe it's nostalgia, but I still like BASIC for hobby stuff.

"Different Globus units needed to be built for different orbits. Moreover, this design only handles circular orbits, making it useless during orbit changes such as rendezvous and docking. These were such significant limitations that some cosmonauts wanted the Globus removed from the control panel, but it remained until it was replaced by a computer display in Soyuz-TMA (2002)."

I have been following the exact steps as outlined in this tutorial video, with no oddities happening along the way: https://youtu.be/twQbHWJF7LA

Well, I was able to follow it up and until we got to the Partitioning part, where he says to load DOS up in the machine, presumably meaning the PC-10 in this case.

The PC-10 loads the ISA IDE to SD Adapter just fine, it even tried to look for Drive C (The SD Card) for like 10-15 seconds, until giving up then and there (as seen in the pic). (ISA IDE to SD card Adapter i got:) !

In other words it seems that the Adapter either doesn't recognise what is on the Card and I've done something wrong in burning the provided image onto it or formating, or it doesn't recognise the card itself to begin with. Its a Brand new 32GB SanDisk SD so that be pretty suprising...

In other words... im out of ideas... i tried different DIP switch configurations and all, but no change. Perhaps the PC-10 III Simply doesnt like the Adapter... or can't run 6.22... im just out of ideas and frustrated. I've had this thing for over a month now with no luck in seeing it run once properly, and original 5,25" DOS Bootdisks are expensive and take a while to arrive. Should I just bite the bullet and go for one? I don't know. Any advice is much appreciated...

I've not tried this but it looks interesting!

With my little Computer Collection ever growing, I think its time to get myself an actual Monitor to use these Machines. So im wondering, what Monitor has most if not all Connection Types and modes of operation to be compatible with most/ if not all Computer from the 80s till the 90s?

I heard good thing about the Commodore 1084 series, though looking online I've seen multiple versions with some connection types missing or that Monochrome mode only sometimes being there. Are there specific Models in that series perhaps? Or should I look for entirely different monitor types? Thoughts?

In the Silicon Valley / San Jose / Bay area, there was a BBS that had a hierarchical message board, Replies were ordered under posts or other replies. In the 80's this was an unusual feature of a bulletin system. The BBS was named for a character from some story. It was a hard to pronounce word/name starting with the letter 'P', and we mostly referred to the BBS as 'Pretzel' as that was a close approximation to the original word. Anyone know which BBS I am talking about?

video features old computer with tui interface at miyata textile co. the operator loads software from tape on MZ-80K2 CLEAR(or CLEAN?) COMPUTER.

screen shows: FOUND MR-463 (DATA) LOADING MR-463 (DATA)

the software writes: ** AUTOMATIC PATTERN PUNCHING SYSTEM ** MR463-01 and then there is a menu.

looks amazing.

>Because in low res some 416x274 is possible, in med res maybe can pull out 832x274 - still little less pixels than in mono.

So I got this Commodore PC-10 III, which the sellers photos clearly showed a different one without that red button at the front and a small Floppy Drive. It also cost me around 200€

On the other hand, from the Inside it seems to have a VGA Graphics card, a Hard Drive and even some type of Internet connector which are all nonstandart !

So for one im quite split on if I should keep it or ask for a refund. But lets asume I keep it, there is another big problem.

For one the lacking Floppy drive was something I really really wanted and would need to build a new one in so I can even do things with it. On the other, much bigger hand, it doesnt seem to work.

Upon booting it up, it first shows some DOS text and then this red screen shows up (sorry about the flash) !

After a bit, it then tries to check the RAM which after a bit returns a "Bad Ram" error. Then it prompts me to press the F1 Key which I do on my Commodore Keyboard which results in the text repeating itself and not continuing. !

In other words, I cannot get past this screen. Pressing any key repeats that Message and the space bar plays a sound for some reason. The best thing I can try is to unplug everything and see if it boots then. If not, I'll inspect the board, especially the RAM Chips... but with not much knowhow this'll be a bit hard...

But yeah, what you all think? Keep it? refund it? Try to get it to run again? Any tips when it comes to that?

> Great tech demonstration here, just a few steps below the Doug Engelbart demo in how futuristic it must have seemed, IMHO. Loved the light pen and macro-pad interface. > > Also, your speakers are fine. The audio for me played mono and right channel only.

I've gotten really interested in old Computers since I got my Commodore PET 2 months ago, so to play some good ol MS Train Simulator and Stronghold 2, I got this massive beauty. Here is a little size comparison between it and my main PC !
