Hi all,
Hoping that someone here can point em in the right direction of getting a recently purchased IBM 2123 up-and-running. I'm not sure if I've casued more damage but what started at two error codes (161 and 163), quickly became three (error 303) then today four (error 404)! Also, the on-board video was working fine and has now stopped. Plugging in a 16-bit ISA VGA card does give me a display so at least I can see something!
Ignoring the failure on on-board video, powering the PS/1 on gives the 2048K memory check, and the in order 304, 303, 161 and then a pause and disk access before 163. I then get two short beeps and then the graphic showing "consult the manual".
I know that the 161 and 163 are common and the CMOS battery is dead. I've replaced the CR2032 but still see the 161 and 163. Am I right in thinking that both of these will remain until I get in to the disk-based config program? Or should the 161 error have now disappeared after replacing a battery? I do have the disk and it loads to the blue IBM screen, but as the keyboard does not work I can go no further :-(
I'm more concerned about the 303/304 errors. I see that these are keyboard-related - or possibly keyboard controller related. I have tried two PS/2 type keyboards - a fairly modern HP one and an older Compaq one. Both of these keyboards now have the same symptoms. Up until today they only gave the 303, but the 304 is new and worrying. Could it simply not like either keyboard? I did have one of them working - very briefly and only once - just after I got the PS/1 but then the 303 error appeared. I have read that this may be capacitor related, but I've no idea which ones on a 2123 board.
I've checked the PSU rails and all fine.
Any help or pointers gratefully accepted! The case is in good condition and I'd like to get this up-and-running if i can.
Thanks,
Dave
PS: Hopefully this post won't appear twice. I'm sure I created it once already but apparently I've made zero posts. So apologies if there are two of the same post.
