C64 pla symptoms

In the C64, a black screen fault is a common failure mode which can indicate all kinds of problems: typically, a missing or improper signal, a data or address bus conflict, an addressing problem, or a stack page fault, all of which can be caused by a power issue or a failed IC.Judging by the symptoms failing RAM seems quite likely, but the RAM has been tested with diagnostic software and piggybacking. The ... so if I go and solder the spare PLA to the partially working C64, I might turn it to a dead machine (I believe the blank screen machine had some symptoms pointing to a failing PLA before it died).SUPER ZAXXON GOLD Beveled for C64 C128 PLA TEST replacement Commodore 64 (NEW) | Computers/Tablets & Networking, Vintage Computing, Vintage Parts & Accessories | eBay!

After that, it sometimes displays the C64 BASIC boot screen and also starts typing by itself. It will usually stop doing that after a short time, and you can finally reboot it and it will work, as long as it's "warm".A defective SID can (next to no synthesizer sound or no digi, which means unable to play samples) produce a black screen. You can debug to remove the SID and turn the C64 on. A C64 will work without a SID chip installed. General Blank or “garbage” screen if shorted (remove to test), otherwise normal screen.

If you search for C64 and PLA, you will get several discussions from the Internet about different solutions, pros and cons. You might be able to source an old stock or used PLA from a similar C64, but the risk is that it will fail suddenly. One standard tip is to power cycle it very quickly on-off-on for a few cycles and leave it on.A bad PLA (U17) is the most common cause of a black-screen C64.

The PLA is not a memory management unit, still, it has a key role in memory control, and decides what chip gets access to memory on a given time.* A screen with a black border and background and characters consisting of horizontal lines or lack thereof, sometimes with one pixel missing in one of the lines of every character - each square a different colour - sometimes with some of the characters changing, flickering very quickly or generally being weird. It can produce colored screen or flashing color garbage instead of startup screen. It can cause intermittant loss of cursor, screen freeze and/or program crashes after warmup and it can put random characters on screen. This chip normally runs hot. It is the most common chip to fail in the C64 and it should run no hotter than the SID.Dry - Spent no time in water. Wet - Spent 30 days in water. Re-dried - Spent 30 days in water, then completely dried. As you would imagine, the more water absorbed by the PLA, the weaker it becomes. Taking pure PLA, storing it in water for 30 days reduces its tensile strength by 6%. Invasive ductal carcinoma (IDC), sometimes called infiltrating ductal carcinoma, is the most common type of breast cancer. About 80% of all breast cancers are invasive ductal carcinomas.
