Hi, on this channel I would like to share my adventures and projects related to:
- Old obsolete computer stuff. Mainly everything that runs UNIX, but I will not limit myself to this area.
- Applied electronics: designing and building devices solving particular problems/needs which I face in everyday life.
I would like to examine / understand / fix / repurpose / and sometimes just do a simple soldering TV.
I’m not an electronic engineer. Sometimes I may get some things wrong.
I’m doing these videos entirely on a budget, so quality of sound/picture may vary.

In this video i will fix broken, non bootable HP 9000 715/75 PA-RISC HP-UX workstation by turning it into a 715/50 (motherboard replacement). I will also inspect and replace fans and a few capacitors in power suppy, and i will fix a broken CD-ROM drive, which was not able to eject a tray. #vintagecomputing #retrocomputer #unix #hp-ux

you need to have the correct card.device in the tool types. The original one is device=scsi.device but there are several others including gvpscsi.device or omniscsi.device to list just 2. With the card you should have been told what the name of the device is. to change it you right click on the HD Toolbox icon and select information to open the panel where you can change to the proper tool icon
Thanks, i have read about the tool types, and i tried some suggested device names, but never got it to work with an SD card that i've had. What is strange, it worked right away with default scsi.device with an old ATA hard disk. My friend told me later, that he got an SD card advertised as "Amiga ready" for this machine, and it was also detected right away, without any additional settings...
@@wojtekmitus yes, sadly some do and some don't. Sandisk are usually reliable. Good to see that it worked with a regular hard drive. Thanks for the video
Fajny ten cały Autoconfig. Trochę podobne do tego co mamy w PCI. Mam taki pomysł na mod do płyty głównej. Coś jakby timeout. Jeśli autokonfiguracja nie zakończy się powiedzmy w 5 sekund to karta zostaje wyłączona (może sygnałem resetu?), zapala się jakiś LED i następna karta zostaje odpalona. Jakiś mały ATtiny by to ogarnął. Dzięki temu zaraz byłoby widać która karta robi problemy a system dalej by wystartował (z drobnym opóźnieniem).
Można by zrobić takiego moda, na przykład wpinając jakiś mikrokontroler in-line we wszystkie linie CFGOUT. Jeżeli MCU widzi na danym CFGOUT stan wysoki, to wie że w danym slocie jest karta, i albo przenosi zmianę stanu na wyjście danej linii CFGOUT do kolejnego slotu, albo jeżeli karta sama nie zmienia stanu, to zmienia go za nią po jakimś timeoucie... Oczywiście taki mod wymagałby cięcia ścieżek...
@@wojtekmitus Myślę, że dałoby się bez cięć. Trzebaby tylko wylutować tego 7432 i zastąpić go mikrokontrolerem.
No faktycznie... Nie pomyślałem o pozbyciu się tego 7432, a przecież przy takim modzie byłby on zbędny.
If you want to sell the ide card (cheap) or the bridgebord we can surely find out something
Hi, thanks for the offer. The owner isn't currently interested in selling any of the cards. I'm currently working on failed cards, and i think i will be able to fix both of them (this will be in the next video).
@@wojtekmitus My bad...... I thought it was your own amiga
used a bunch of 710 machines in the same era (and a bunch of rx7000 X terminals)
