I want to raise a question to this expert forum :
I own from 1989 a Mac Pus, acquired at that time as a "used" machine upgraded from a Mac 512 by the original owner.
I bought in 1990 a 40 Mb external hard disk that fit in a metal box standing just under the Mac Plus.
Two years ago, the hard disk just died. I look around on ebay and had a lot of troubles finding a SCSI-1 disk under 1Gb. I found a Quantum Fireball ST2.1S that I inseted in the original box.
By that time, I was able to start again my Mac Plus using a 4Gb external disk containing a Quantum Fireball SE4.3S of 4,2 Gb : using the modified version of Apple HD SC Setup 7.3.5, I was able to create a partition of 400Mb with a system 7.1 dedicated for the Mac Plus. This assembly just boots fine. javascript:emoticon(':b&w:')
If I perform the same with the Quantum Fireball ST2.1S, the Mac Plus never boots, standing with an exclamation point.
javascript:emoticon('
')
If I put the two disks on a SCSCI chain, the SE4.3S allows boot, and then the ST2.1S is mounted.
I just got a Quantum TRB850S, older, and same problem : no way of making it bootable.
javascript:emoticon(':-X')
By the way , I was never abale to use the "interleave hiden option of Apple HD SC Setup 7.3.5 : I got the acces thru the Command-I option, type 3 but all HD are still formatted with 1
Can anybody can provide any help or explaination ? [?]
