Preliminary dump of the voice data from a McDonnell-Douglas H05A0035-10 Central Aural Warning System. I believe first flown on the DC-9.
Voice data was stored on three 256Kx8 EPROMs. I traced out a schematic of the voice board and dumped them in-circuit, so there was no need to try and desolder the chips from the heavily conformal coated multilayer board.
It’s a routing table. 😂 https://twitter.com/bmcbass/status/1430574621401694212
cleaning out some surplus telecom hardware from my basement, in case anyone is interested in items from https://osmocom.org/projects/miscellaneous-projects/wiki/LaForge_surplus_202108 let me know
Danke an die Hinweise. Das sind Perlhühner!
Total sympathisch. Hab früher selbst viel Perl gemacht.
