Greetings! I have an NEC PC-8201a with Rex and Steve’s memory upgrade. It’s worked great for many years but recently I started getting corrupting files which I attributed to TS-Dos. After TS-Dos 4.2 I’m only getting corrupted files on bank 2. MEMCHK returns one beep on bank 1 but multiple beeps (five fast) on bank 2. I replaced Steve’s memory board in bank 2 with two known good stock ram chips but still got multiple beeps from MEMCHK. I’m not blaming the ram expansion or my known good ram chips as those test good in bank 1. Can someone direct me to what to check next? I got a scope(s) and tools/experience doing board level repairs. But I’d like the lists insight before I go digging in. Any help you all could provide would be greatly appreciated.
