Ups, it is shipped from the US...20$. This maybe a showstopper for that option.

^^Ah OK, many thanks! especially in the 5150 as it uses a non-standard ROM and you have to build an adapter... Why don't you just build an adapter? Built it. But my approach should be much easier and more universal. The ISA card can be used in any System with an ISA slot from XT to Pentium without …

Hah - indeed this ROM card is exactly what I looked for and should do the job. Price is also OK - but "Out of stock" 🙁 2nd option is not what I like to do as I like to work without BIOS on the Mainboard. Many thanks for the link!

Quite unusual Socket 5 board ALR "Triton Classic" with wires on the back and 2 differnt cache modules? IMG_9929r.jpg That is an interesting board. I have never seen those memory sockets on a motherboard, but a lot on video cards. Yes, agree. Dont know if these are regular memory or cache chips. …

Then its actually a 27C256, half the size. The image you read is correct, but includes 2 copies. 74S287 is most likely a logic IC (74LS287), you can also check it with the TL866. Indeed, than the beep indicates a short. Leave CPU+ROM uninstalled until fixed. Check the pins on the back if some are …

Do you hear the beep also without CPU installed? Read the ROM as 27C512.

Short update: I built such "over-IC" adapter but unfortunately it doesnt work while the ICs are in circuit. I also "piggybacked" the rusty 74LS158s but no change. I am aware that I dont have to expect any numbers on the post card, but some lights should flash on it while Post-sequence is running and …

Good job so far. Since you have a TL866, it has a logic IC test function. If you can find/build an adapter that fits _over_ the ICs you may be able to test them without desoldering. A sort of inverted socket. I have a similar adapter that I can place over eeproms so I can read/reprogram them …
