Tandy TRS-80 Model 102
|Were these machines named after the Ford Model T?|
The Tandy 102 Portable Computer is a A4 size computer like the later Cambridge Z88, but with a few differences...
4 x 1.5V AA cells
|Production year: 1984||OS: - Undefined -|
|Type: Laptop||RAM: 30KB(32?)|
|Display: Internal LCD||Resolution: 40x8 chars|
The first thing you notice is the very good keyboard... the next thing is the thickness... It's at least 50% thicker than the Z88. Also, the case is 'creaky'(at least mine is).
Now for some gritty details:
What else can be said?
- External connectors:
- RS-232 - A 25pin connector for serial comms.
- System Bus - A long (2x20 female) connector. Is there anything available? And what is the pinout?
- Printer - A 2x13 male connector. Definitely not a normal Centronics connetor. I wonder about the pinout...
- Phone - This is a 5pin Din connector as used the XT/AT class PC's... Does this indicaate that this computer has a built in modem of some sort?
- Cassette - A 5pin Din connector. Obviously used for storing and retrieving fileson a cassette deck.
- BCR - this is a 9pin male connector on the side of the computer for a Bar Code Reader.
- Expansion socket? - There's a mysterious DIP (28pin IC socket) beneath a cover on the underside. It looks like it's for either a RAM or ROM chip.
- On the lefthand side, there are two mysterios switches marked DIR - ACP and ANS - ORIG. It might have to do with the possible built-in modem.
(ANSwer - ORiGinate?)
- There is a VERY prominent Reset button next to the system Bus on the top edge o the computer... Is it because it's running M$ software?
- There is a switch on the underside seemingly to enable/disable power to the memory...
- Abowe the keyboard, there are a row of function and direction keys. The 4 leftmost keys are marked Pause, Paste, Label and Print. the 4 rightmost keys are direction(arrow) keys, and the 8 middle keys seems to have different meaning depending on which program you're running. ([F8] seems to usually mean Close/Exit).
Sometimes, the function is noted on the bottom row of the screen.
- Built-in programs:
- Basic - Looks like a ordinary oldfashioned Basic with line numbers and all.
- Text - A text editor.
- Telcom - A terminal emulator of some sort.
- Addrss - A contact database or something. Gives the error 'ADRS.DO not found - Press space bar for MENU' Crap!
- Schedl - A time manager or something. It too gives a nice error 'NOTE.DO not found - press space bar for MENU'.
The user interface is not exactly intuitive... I still haven't figured out how to set the Time/Date...
