- Having a problem booting my 4D/20. One day, on startup it came up with the error
- listed below. It's a 12Mhz, 12M RAM, 380M hard drive (Micropolis), old
- GR1.1 run of the mill machine. The fault is pretty immediate and shows up on
- console terminal (not screen). Would appreciate info on what this is, how to
- fix it, or where/how much it would cost to get it serviced. Tried the trivial...
- reseating SIMMS, checking for heat producing chips, reseating boards, shortening the SCSI path to the minimal (had a QIC150 on it) without luck.
