Re: Maintaining Hardware / fesability of keeping hardware running

The 3.45v rail is rated at 675Amps, that is instant death current. No, you would not even feel anything if you touched this power supply. It would be enough to instantly vaporize a screwdriver, but luckily we are not screwdrivers. 3.45V@675A does not tell you the behavior of the circuit without kno...

Re: SoftImage 3D 4.0 Install Help ?

Softimage should not have died. The fact that they sold themselves to Autodesk was a big surprise and sad for me. Everyone knew it was going to be pillaged for uses in Maya and Max. Maybe a small chance the sales would save it and it would stay relevant. BUT.... had they not sold or been bought by ...

Re: An item is only ever worth what someone is willing to pay... :)

There are some things that are just objectively ridiculous:
https://www.ebay.com/itm/Roland-sound-m ... 2976283212
This unit sells for $200-300 on any other day. Just being in mint condition doesn't make it worth ten times list price! And '80s nostalgia doesn't apply.

The main thing to avoid is touching them with your hands. There is some risk that the bitterant used in most duster cans could leave a deposit.

Re: CRT Projector for Bedroom Entertainment Setup?

Projection CRTs are more likely to be replaced for other reasons than just burning out. Burn-in on the phosphors is a big problem and it affects these tubes more than regular display units. You should be very careful about on-screen display characters, network bug logos, computer menus, or anything ...

Re: CRT Projector for Bedroom Entertainment Setup?

Projectors have a specified throw distance, which is the distance between the lens and screen at which it can focus. This will be specified with the lens (or with CRTs, lenses) that the projector can use. Unfortunately, from what I can see of some Barco literature, they choose to only print the scre...

Re: An item is only ever worth what someone is willing to pay... :)

Very true, and I'll add a very important price factor, which is whether an item is the last or greatest version that was produced. It makes a machine much more desirable to hobbyists because they know it is better than the others of the same type or platform. For example, the Macintosh IIfx and SE/3...

Re: R5000PC to R5000SC?

I assume you mean for an Indy IP24; I don't think the O2 processors went as low as 150 MHz. As far as I know, all R5000 chips contain secondary cache controllers. The issues you may face are: 1) The processor cards sold as R5000PC may not have been fully tested and qualified for use with external ca...

Re: ColorLock internals

I have not seen the circuit board in the ColorLock, but simple devices have simple schematics, which can be reconstructed in single-digit hours of time, with the right approach. Sometimes the value is not critical, but knowing this depends on its role in the circuit. For example, by knowing that the...

Re: ColorLock internals

Small SMD capacitors are rarely marked in any useful way. The only means of replacing it are
1) Taking a working unit, removing the capacitor, and measuring it
2) Guessing a value from the schematic and putting one in
