When we dreamed of KZbin back in he 1990's, we imagined users groups presentations like this. Thanks for sharing.

Truly ... we are peek internet!

[@michaelstoliker971]

The intel 8080 ran CPM and the Z80 was created to make a CPM computer that was more affordable. When in doubt, try Ctrl-C for Break.

[@fractalMD]

Our technique is more like smash at the keyboard then wind up rebooting it anyway.

Thx! Stay tuned!

We thought it was cool!

[@soupwizard]

11:57 that is definitely a cool display! that glichworks stacking sbc, cf card, and display board is super neat.

[@CallousCoder]

OOOh wow! Bubble screen! That's been forever since I've seen those. I also never worked wit an 8085, only 8088, 8080 and 8051 (which technically is a micro controller).

[@fractalMD]

Bubbles forever!

[@nathanwagnon5406]

CP/M? And I thought I was geeky with my PIII/OpenStep machine. Wow rave on! I remember seeing my first CP/M machine it was an unbelievably big luggable with a 5 inch screen, keybord in the top cover of course! You guys are fortunate to have it in single board form, so tiny! I should have hung onto my z-80 powered Timex Sinclair wi the 16k memory upgrade! Fun Times!

[@fractalMD]

We are just getting started with the geekiness! 😃

[@JordynBaby63]

My first job out of college was designing and coding 8085 computers to run boilers and chillers for hospitals and such. So much fun debugging the code with an oscilloscope

[@fractalMD]

That is just nuts!!

Hey Taylor and Amy, it was great hanging out with you at VCF!! You already kicked my butt and have a Glitchworks product actually assembled and powered up, as opposed to the unassembled kits I have. 😞 I have some pictures I can send you if you are interested, let me know.

[@fractalMD]

Sure! Loved chillin with you! Glad we weren't too too disruptive as agents of chaos. I'll bet at least one photo is all of us up on those concrete blocks. For some reason that was hilarious. Especially as a vantage point to harass good ole Mr Usagi Electric himself. 🤣

[@Ran-tan-tan]

@@Ran-tan-tan Maybe? I feel like I saw a lot of filming while we were peanut gallery-ing!

[@MichaelZweifel]

Welcome back, CoCofest was great. We missed you !!

[@fractalMD]

We hated we couldn't be there. :( Various unexpected life events got in the way.

[@CurtisBoyle]

@@fractalMD - We understand. You were definitely missed (as were several others who also had unexpected life events), but we tried to make up for it as much as possible! When I went to show the little graphics demo I did for you during the NitrOS9 seminar - it crashed. Found out afterwards that the air vent from the projector was blasting right into my Coco which caused it to start overheating. After it cooled down (after the seminar was over, naturally), it worked fine. So I got to show it to people at the Fest... but I don't think you and Taylor have seen it yet. lol.

[@fractalMD]

@@CurtisBoyle ❤️❤️❤️

[@CheshireNoir]

One of my memories of university was learning 8085 assembler on an SBC with a hex keypad. Whoah. Back in 1991 or there about. When dinosaurs roamed the earth. Can't remember a single bit of it. 😀

And the Earth was cooling. I know the feeling!

There's so much great stuff in this episode! From the casual mention of Bill Herd presenting that amazing real world implementation of your logo, to the breathtaking bubble display, to the hint at a future Model 100 episode (the Tandy Model 102 is definitely the favored machine in my collection).

[@fractalMD]

We really did cram a lot in there, didn't we? 😁

[@robertjohansen7482]

It was nice meeting you at VCF East. I would get a kick seeing your video taken through the old TV demo in the njarc museum. Best wishes, take care

Taylor and Amy we (VCF and the CDL Makerspace) was glad to have you there. I watched the MC10 video, loved it. 🙂 Hope you get a chance to come back again. I'll see if we can get Glitch (Jonathan) to do some Motorola board (6800, 6801, 6809, etc.) We'll have you running Flex or OS9 in no time.

[@fractalMD]

It was a total blast!!!! Y'all are great.

[@olavl8827]

I have been following this channel since you were mentioned on Hackaday. You ladies always seem to have so much fun, it's contagious. Love it. I wonder if there has ever been an episode where Amy does the soldering?

[@fractalMD]

Just one if you can find it! I can do it but Taylor is EXPONENTIALLY better.

[@tomwilson2112]

How did I not know about this channel until now?? The first computer I learned assembly language on was an Intel SDK-85... a single board 8085 computer with nothing but an LED display and hex keypad. (We quickly moved to CP/M computers, still using the 8080 style instruction set.)

[@fractalMD]

Welcome to the party!!!!!

[@KeritechElectronics]

Nice Erlenmeyer flask! 2:10 I think I saw Usagi Electric back there, but I might as well be wrong. Those bubble displays are so lovely - vintage calculator vibes for sure. 8080, AT-AT... what's the difference? Maybe AT-AT had 8080s in their onboard computers, haha.

[@fractalMD]

This is now start wars canon.

[@GeoffSeeley]

You should add a serial port to that SBC and use good old Kermit to get CP/M files from another computer, although getting Kermit on it might be a bit of a chicken and the egg scenario but you'll figure it out.

[@fractalMD]

I like all this frog and chicken talk.

[@TSteffi]

About CPMtools: They are meant to work only with disk images. On linux, you can also pass them a "/dev/*" device and it will use that. On windows, I haven't tested that. You also need a file called "diskdefs", that has format information for a bunch of disk types. And you have to give each CPMtool a command line option "-f " to tell them which disk format to use.

[@fractalMD]

Ain't nothing just easy!

[@TSteffi]

@@fractalMD The issue is, CP/M didn't define a physical format specification. It was left to the system manufacturer to define a floppy format. So now there are tons of different formats, none are compatible with each other, and the disk (or image) itself doesn't tell you what it is. The manufacturer would put this information in the DPB, Disk Parameter Block, which is part of the BIOS. So it is technically stored on the boot tracks, but since the location isn't specified, we can't use it. Modern implementations of CP/M 2.2 often use a format that uses 8 MB images on a larger disk, because that was the maximum size of a drive under CP/M 2 and also MP/M 2. But some also have custom definitions. You will have to ask the developers of your board for the format they used. I looked at the documentation for the Glitchworks board and it doesn't say which format they use. But it says the internal flash that is used as A: drive should have PCGET and PCPUT for up/downloading files, using the Xmodem protocol that is supported by TeraTerm. So that is one way to get stuff onto your board.

Like seriously the most fun.

[@Commodore128Mode3]

Hey Taylor and Amy: The Toshiba T-250 (the first computer I've ever used!) and its smaller brother the Toshiba T-200 both used the Intel 8085 microprocessor. Now you know another two computers that used it :) The Toshiba T-250 ran CP/M 2.2, had 64k of RAM, 58k TPA, dual 8 inch floppy diskette drives. It had a built-in 12" monochrome monitor. Must have weighed over 100 lbs--no kidding! Also: don't forget that your beautiful Commodore 128 is compatible with your single board in CP/M mode ;)

[@fractalMD]

So much beauty in the world!

[@fractalMD]

No you are are!!

[@c.allison8761]

The 8085 was used as the second processor in the zenith z100 and z120 to run CPM it also had an 8088…

[@fractalMD]

Which is kinda awesome.

Okay you've made me want one of these. I've not yet succumbed to any of these project boards (since I got an original RPi when it came out) and would love to program some basic games for this using inputs and that bubble display. Thanks for the entertainment!

Great choice of t-shirts. Clearly the Empire has the best hardware! Amazing to see MS basic running on DR CP/M on a modern piece of kit. You have to get Zork running next!. I am afraid getting legacy file systems to work with modern OSes can be a bit of a pain.

Hi, I saw your video and I fell in love with it. On Sunday I bought a trunk with thousands of components at a flea market, I understood that there was something good in the middle. in fact I managed to find different versions of the 8041, 8085, 8088, 8086, ram, rom, eeprom, plus hundreds of TTLs as well as thousands of transistors, capacitors, .... etc. I wanted to know if you could help me choose the best versions of components and build a computer from scratch. It has always been a passion of mine. I hope you can help me, thanks...
