Hi everyone, Thanks for all past help for this IBM nube.
I'm not getting any ram past 64K after a cold boot. I get no errors, no 201's, nothing. I only have a monochrome video card installed, no FDD. After boot, long pause with flashing cursor, then Basic comes up, it shows 62940 bytes free (= about 64K ??). The MB has all banks populated with the same numbered IC's. (TMS4164-20NL, AP8414)
Switch 1
1 on
2 off
3 off
4 off
5 off
6 off
7 off
8 on
switch 2
1 on
2 off
3 off
4 on
5 on
6,7,8 off
Jumper P4 is shorted M-C
Socket C28 is empty
Is my system running properly, or should there be something near 256000 bytes free??
Thanks
