I am posting this call for help for a friend who has lost his netnews feed. He has upgraded his Mac with MacPlus ROMs and has a problem with booting his Tecmar hard disk now: > .... My Tecmar > hard disk died, so I bought a Micah Drive and got my mac upgraded to the > new ROMS. Then I thought what-the-xxx, I'll try to get the Tecmar repaired. > I did, and now have an incompatibility: the Tecmar boot disk is incompatible > with the new ROMS. I remember seeing stuff on the network awhile ago > (when we had net.micro.mac) about how to hack your boot disk to let it work > with a MacPlus or Mac with new ROMS. > ... > I would happily send > whatever bucks someone wanted to whoever would mail me a Tecmar boot disk > that works with HFS.

RE: the Tecmar boot disk is incompatible
with the new ROMS. I remember seeing stuff on the network awhile ago ...
1) have you tried booting while holding the mouse down? (or is it the option
key?) to boot to the floppy ...
on the other hand, I don't recall a problem when booting ...
2) have you tried your Tecmar on someone else's old Mac?
3) you don't mention what repairs were made (nor the cost and who did it ..(-:)
but are you sure you have a properly formatted drive inside?
In general, you have to make your Tecmar your System-drive (do I remember this
right? has it been that long already?) And you have to install the Micah-mount
DAs there.
The resources you need to use your Tecmar are:
DRVR -20 .TDISK driver
FIXX which contains 2: -20 and -21
ICN# 555 the Tecmar icon
STR -555 I don't recall
INIT -31 which you have to renumber in order not to clash
with Apple's 31. best a number higher than 31,
for a reason that escapes me now (look at the time of
my posting).
-------------------------------------------------------
if the drive is broken in a Tecmar you can replace it with some other brand
(any other) which isn't very expensive but likely to be better.
Don't forget to create Volumes and clean up fragmentation every so often.
makes a GREAT difference.
if the logic is given you trouble, find another broken Tecmar and see if
component swapping gets you one working and one broken one.
Yes, you can hack the Tecmar into a SCSI-drive ...
PS: has anyone heard if Tecmar is still in business? does anyone know a
phone-number that they still answer?
PSPS: sure I'll send you a disk if you still need one ...
