Title: GVP A530 Turbo and HOT PALs
Post by: -BobW- on April 28, 2021, 05:09:52 PM
So I have a GVP A530 with a full 8Megs and the hard drive replaced with a SCSI2SD adapter.  Life is good.  However, it gets hot.  This afternoon I have been running it without its case to get an idea where the heat is coming from.  CPU and FPU are cool as a cucumber.  Ram is also fine.  It turns out one of the PALs is really hot.  Like so hot I can't keep my finger on it for more than a second.

Is there a source for these PALs?  Can they be copied?  Any other thoughts?  I plan on adding heat sinks to at least the hottest PAL.

Can't say I know of a source for programming them.

However, i do recall the a530 running hot, and checked the datasheets for the components. The PAL and Mach130 chips have same operating characteristics (good up to ambient 75 degrees centigrade, 125 degrees centigrade maximum operating temperature).

Add a heatsink or two if it makes you happy, the unit tends to shut down when it gets too hot and won't work again until it's cooled down.

I haven't come across any downloads for programming any of them. Perhaps nobody ever tried, you have to desolder them to do that.

I'm mostly concerned about preserving this thing.  I'm going to go ahead and install heat sinks.

As a side note all my PALs are socketed so no desoldering.
