/***************************************************************************
TEC-1 driver, written by Robbbert in April, 2009 for MESS.
The TEC-1 was a single-board "computer" described in Talking Electronics
magazine, issues number 10 and 11. Talking Electronics do not have dates on
their issues, so the date is uncertain, although 1984 seems a reasonable
guess. Talking Electronics operated from Cheltenham, a suburb of Melbourne.
The hardware is quite simple, consisting of a Z80 cpu, 2x 8212 8-bit latch,
74C923 keyboard scanner, 20 push-button keys, 6-digit LED display, a speaker,
a 2k EPROM and sundry parts.
The cpu speed could be adjusted by using a potentiometer, the range being
250 kHz to 2MHz. This is a simple method of adjusting a game's difficulty.
We emulate the original version. Later enhancements included more RAM, speech
synthesis and various attachments, however I have no information on these.
Pasting:
0-F : as is
+ (inc) : ^
- (dec) : V
AD : -
GO : X
Keys:
0 to 9, A to F are on the key of the same name.
AD (input an address) is the '-' key.
+ and - (increment / decrement address) are the up and down-arrow keys.
GO (execute program at current address) is the X key.
SHIFT - later monitor versions utilised an extra shift button. Hold
it down and press another key (use Left Shift).
Whenever a program listing mentions RESET, do a Soft Reset.
Each key causes a beep to be heard. You may need to press more than once
to get it to register.
Inbuilt games - press the following sequence of keys:
- Welcome: RESET D 1 + 0 2 AD 0 2 7 0 GO GO (Paste: D1^02 -0270XX)
- Nim: RESET AD 3 E 0 GO GO (Paste: -3E0XX)
- Invaders: RESET AD 3 2 0 GO GO (Paste: -320XX)
- Luna Lander: RESET AD 4 9 0 GO GO (Paste: -490XX)
Thanks to Chris Schwartz who dumped his ROM for me way back in the old days.
It's only taken 25 years to get around to emulating it...
Differences between tec1 and tecjmon:
On the tec1 a keypress is indicated by an NMI from the 74C923; but on
the jmon it sets bit 6 of port 3 low instead. The NMI code is simply
a 'retn' in the jmon rom, so we can use the same code.
The jmon includes a cassette interface, a serial input connection,
and an optional LCD, but the games of the tec1 have been removed.
ToDo:
- After a Soft Reset, pressing keys can crash the emulation.
- The 74C923 code may need to be revisited to improve keyboard response.
Sometimes have to press a key a few times before it registers.
- The 10ms debounce is not emulated.
JMON ToDo:
- Add LCD display (2 rows by 16 characters)
