There are some pal chips on that POST card.They might be protected though. Very good card.Does it work? Yes works and gives a nice firework. Dont know what all the LEDs mean. Also dont know about the PALs, my Minipro seems not to be able to read them. 20230430_223454.jpg 20230430_223450.jpg …

The POST-card also looks interesting, will dump the ROM later Good luck with that. As there is no sticker over the EPROM window, you'll be lucky if the data is complete, if it's not fully erased (depends how long it's been in the light with the window open to that light). Yes I noticed that. See …
