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.

Console DUART test passed
Memory walking bit test
Exception at: BIC02724
Cause:0000401C
Status: 00580000
Bad Vaddr: FFFFFFF7
Parity Err: 000000AA
LIOStatus: 00000009
ErrorAddr: AAAAAAA8


Occasionally I would get (in addition, and first):
Address: A0000000
Expected: FFFFFFFE
Received: 55555555

and Cause would be 3000401C

Something is *seriously* wrong with your memory, or the data path
to it.  If you have more than one bank, try using only one bank,
switching SIMMs one at a time to find the bad SIMM.  If you only
have one bank, you probably need to call the hotline.
