But didn’t SCSI interface to connect an external CDROM :( only I had ASYNC Multiplexor card

Today I’ll try to boot from network using another VAX machine adding this to cluster. But I need figureout how to install software over ethernet.

Also I need to check all PSU capacitors because some times not power up well.

@@tomeucapo The capacitors on the secondary side are sometimes difficult to reach, I haven't managed to replace them all myself and sometimes my machine switches off as well. I think I have make a fourth of my PSU video series...

@@DECcomputers I reached and removed. All 100uF electrolithic caps fluid are leaked! First I clean it and replaced all this caps :P

First I removed battery pack and added new working DSSI SCSI Hard Disk. Now I’ll try to re-install VMS 7.0 or 6.3

Yes Its 70MHz I’m so sorry! damn dyslexia.

So sorry! Another case of non-english person try to spend his time to create some content videos in English on his spare time to share his experiences! If you don’t understand the video simply not follow me! Thanks and sorry! I try to learn how to improve speak English. I do the effort for english people. Another time I’m so sorry! Maybe made my next video in Catalan, maybe understand better. Or its better do rm -rf / on my UA-cam Account? Maybe you prefer the second. 😂

Ahh yes, thats it!

Thanks to you! :)

Yes, is horrible frequency refresh rate! I'm sorry

Not upgraded yet! I see your comment at eevblog forums about this: www.eevblog.com/forum/testgear/hacking-the-rigol-dho800900-scope/2675/

Hola, si tiene otro PC con disketera de 5”1/4 compatible con 360KB y MSDOS podria crear un disco bootable con el comando SYS. Si no hay la opción de que instale un dispositivo Gotek que le permitirá emular discos con un USB. La otra alternativa es comprarse un XT-IDE monotech.fwscart.com/product/xt-ide-deluxe---bootable-isa-cf-ide-interface-card donde le puede poner una compact flash cómo unidad de disco duro.

@@tomeucapo Gracias, lo haré ❤

@@CarlosTorresCali El sistema operarivo que tengo instalado en el 5150 es el MSDOS 3.30. Pero por que tengo los discos originales. La versión 6 tambien podria funcionar. Puede encontrar las imagenes en winworldpc.com/home

The man is tired because it is 2:00 in the morning

Esta versión la compré en mi época de estudiante a mediados de los 90. Són los CDs orginales que compré en 1996.

@@tomeucapo ¿Y los libros? No tengo manera de encontrar versiones en castellano de programación de Windows. Es un fastidio.

@@reactsos La documentación de microsoft venia en formato electrónico en los mismos CDs. Luego tengo el Programación en Windows 95 de C.Petzold que lo compré a parte

@@tomeucapo Pues creo que es justo algo que busco, lo raro, que no esté en formato virtual (en español) en ningún lado.

@@reactsos ​​⁠A dia de hoy es dificil de encontrar, ya en 1996 cuando lo compré la versión de estudiante tampoco llevaba los manuales impresos en papel. Todo estaba en formato digital en el mismo CD. Por eso en esa epoca me compré el libro de Chales Petzold: Programación en Windows 95.

No lo he usado con PPC. Si que he usado otros compiladores de C/C++ sobre PPC, el IBM Visual Age C++

Tested on my 4K flat panel, but in 4K monitor scale image. Resolution 1024x600

Me too, when starting to tinkering with PCs get copy of Turbo Pascal 3 and start to learn Pascal :) I remember my fathers have some copies of Turbo C, Turbo Pascal but he never use.

When I was child starts with BASIC of course. My first programming language was BASIC in many forms and types: VIC20 BASIC, GW-BASIC, QuickBasic, Turbo Basic… Lovely days ;) Also in PC days are using Turbo Pascal and Turbo C, also Assembler too for example combining Assembler code into BASIC programs to make some special screen text effects like scroll up and down screen.

Me too. When I was undergraduate student and before in high school start to learn Pascal with Turbo Pascan and C with Turbo C. :)

Of course, I’m so sorry I need better microphone :)

You can connect with HDMI. Can make a video doing this.

My pleasure!

Also I still learn about new functionalities. I try to prepare the next video about LXI and network remote managenent of scope.

DHO 804 can decode different bus types: Serial and Parallel. In serial mode supports RS232, I2C and SPI. If you system use this type of buses thats OK can decode it. Wireless outdoor thermometer not wired, maybe you cannot decode it. For example if thermometer sensor connected with I2C wired bus, then you can decode dialog. For your situation maybe not.

I think about touch screen and UI buttons like close window button is little than finger and some times when I try close window UI not response very well. But in general is very versatile scope for this price. In general not bad oscilloscope quality/price relation not bad, usability not bad. Maybe need improve some UI elements for better usability with touch screen. Also is my first RIGOL oscilloscope with touch screen and some functions accessed from Rigol start button or menu button instead direct access buttons like SIGLENT or Tek scopes than have screen lateral direct buttons to access measurement functions or other menu functions. Thanks for your comment! Cheers!

Thanks good idea. In my job we using Visual Studio 2022 with C++ its totally different but still also compatible with old Windows APIs. I make this video because when was more young (1995) buy Microsoft Developer Tools for Students and my first contact with VB5 and VC++4. Before than I used other MS Tools and Compilers like Microsoft Quick Basic and Microsoft Basic Professional Developer System. In these days I used also lot of Borland compilers like Turbo Pascal and Turbo C for DOS.

What do you mean?

@@tomeucapo "the name Borland Pascal was generally reserved for the high end packages (with more libraries and standard library source code) while the original cheap and widely known version was sold as Turbo Pascal." end of quote. But I wanted more gory technical details about it... I guess I'll have to google it :))

Hi! yes TP7 and BP7 are different products. BP7 From WinWold: "It includes both the DOS IDE and compiler as well as the Windows IDE from Turbo Pascal For Windows"

Always I used Turbo’s products from Borland but never used Borland Pascal for Windows. In the past I started with Turbo Pascal 3 and later v6 but in windows jumped to Delphi and Microsoft Visual C++ but never used Borland Pascal for Windows in the past. I reviwed Borland C++ in other video to quick review (not in depth) how it works on windows.

From Wikipedia: For versions 6 and 7 (the last two versions), both a lower-priced Turbo Pascal and more expensive Borland Pascal were produced; Borland Pascal was oriented more toward professional software development, with more libraries and standard library source code. The name Borland Pascal is also used more generically for Borland's dialect of the language Pascal, significantly different from Standard Pascal.

Maybe, but this is C64C keyboard

It should fit as the VIC-20 and the C64 and c64c use the same keyboard. VIC-20 case is the biggest.

@@G7VFY I know it, thanks. I try to find one VIC20 case at ebay to fit my board into it!

Me too! ;)

How? What? Starting NT4 on 60 sec? I replaced my mechanical HD for Compact Flash. CPU AMD K6-233MHz and 64MB of RAM

@@tomeucapo ok. this stuff is quite interesting you are a system and software engineer can you teach us what you have learned so far in some kind of youtube series

@@GenZee471 when I have spare time on youtube try to do some interesting videos. But I think if I talk on software or hardware retro 80’s and 90’s.

You are interested in some special?

@@tomeucapo yes

Thanks!

Awesome! I never used this setup before. But when I start with TP3 I using 8086 PC with dual floppy (no HDD) and started to learn Pascal when was young!

I’m sorry on my next videos try to solve.

With Apple II+Z80 Softcard? Or other machine?

He is my assistant! Lol!

Turbo Pascal doesn’t support Extended Memory. But since Borland C++ and Borland Pascal have new targets can support this. You can try Borland Pascal 7 instead Turbo Pascal.

@@tomeucapo thanks, I'll try BP7

I'm sorry I working on it to avoid this voice issue in the future!, thanks and sorry

Is not VS Macro, is MS Macro Assembler for 8086 for DOS! if i wanted to use modern assembler with VS i would have used VS!

Yes, don't worry I try to upload to my github repo: github.com/tomeucapo/DOSStuff

@@tomeucapo thank you so much sir! That really helped me a lot

@@ZeroCool2211 One note! The Box function not implemented yet, this function used to draw box arround the menubar.

In my childhood my father buys first computer (Rockwell AIM 65) and then ZX81 with 16 KB of RAM. But the one that I really touched and learned my first steps with BASIC was with a VIC20, then came Dragon 32 and then a CPC6128. I rembember when learn with Turbo Pascal 3, my first structured programming language was learn. You were the most beautiful years of my childhood, I have to thank my father for introducing me to that world that in the end has been the specialty with which I work on a day-to-day basis, software developer and engineer.

@@tomeucapo >>I have to thank my father for introducing me to that world << That's what we have in common 🙂

I remember also these days but in my case at 90s!

At the same time that I was tinkering with Turbo Pascal, migrate my old GWBasic first programs to QuickBasic 3 and later 4.5 my experimental little programs like as file encryptor or litte inventory management with sequential files, good times!

Awesome! When was young start learing another languages like Pascal and C, I began with Borland accidentaly, my fathers have some copies of Turbo C and Turbo Pascal that never he used that and give, install and learn to use. I remember in these days without internet (early 90s), learn by examples into journals like as PC Magazine or Byte. Very interesting age before I start my career at university as Engineer. At the end of 1995 buy first Linux spanish journal that sells with copy of Slackware Linux, remember create to floppies (boot and root) and installl manually on my old 486 DX2 at 66MHz (remember dificulties with configure XWindow manually with XF86config). I known Minix when was university student in Operating Systems course that show how implements OSs like Unix showing how it works Minix (Tannembaum OS).

All you just mention ,was my world too. Xconfig86 server ( so many options) .Then one worked with your card by magic .A friend of mine sold early Linux booklets with a CS and a boot floppy disk ..Then came FreeBSD ..we used to leave the computer running for weeks .No crashes .That was impressive back then
