Anyone looking for a FREE "Toshiba T1100 Plus" parts unit (you pay
If you're trying to restore a IBM Convertible laptop some of these
parts may be interchangable as well. This system has a bad LCD (you
can still use with an external monitor), flakey A drive (needs
and a weak or dead battery (I am attempting to re-charge overnight).
Otherwise the system works. The B drive works (you can boot from
B), the memory upgrade works, and the motherboard is OK. There is
an untested internal modem. No power supply, sorry. I will make
you a copy of the DOS disk that came with the computer. Let me know
Today I received two free dual 3.5 drive Toshiba T 1100 Plus model
laptops with one set of manuals and some misc. software including
the original DOS disks with diagnostics. They are ~7.1 Mhz 80C86
systems, very similar to the IBM Convertible laptop. They look
almost the same and I bet have some interchangable parts, especially
the Epson drives.
One system had a bad LCD display but I could access it with an
external monitor. Otherwise the system worked well (except for dead
battery). The 2nd system was in much better shape, but it had an
inconsistent "A" drive and I could only get it to boot from A>
I decided to take apart both laptops to make one fully functional
After a little poking around I decided to swap the A drive from the
one system into the other. I could have opted to simply switch the
LCD display (and possibly the internal battery), but the one unit
was considerably yellowed and I wanted to try to restore the better
looking system if I could. Taking that route presented a risk
because I had to take the laptops completely apart to free the disk
drive cables from the chassis in order to switch them. After
patient disassembly I was successful.
I also fixed a Toshiba DOS 3.2 disk with diagnostics.
I also have not yet tested the modems.
Fun. One of my first jobs was to test, fix, and configure laptops
of that era. In my LCD laptop collection I have a Grid Plus,
Virtual Computer "Commuter", and the T-1100 Plus. Related systems
include a few Commodore SX64's, a Compaq 286 luggable, and an IBM
