The Memory Board
This computer like all other computers comes to life though software, software that runs at start-up, and so here we introduce TUTOR.
 
TUTOR
 

TUTOR is a ROM resident 68K Monitor program originally designed for use with the Motorola MC68000 Educational Computer Board (MEX68KECB).

The version of TUTOR here (V1.3.01) has been adapted for use with the Mega-68000 Computer System fitted with the following boards:

1x Memory Board with 2x AT28C64B ROMs fitted

 
J1 pins 2-3 short
J2 open
JB1 pins 5-6 short
JB2 pins 1-2 short
DS1 FC (ROM FC0000-FCFFFF)
DS2 00 (RAM 000000-00FFFF)
 
1x Dual 6850 Board
 
J1 TBA
JB1 TBA
JB2 TBA
DS1 F1 (ACIA F1xxxx)
 
The TUTOR ROM is an AMD Am27C4096 256K x 16 UV EPROM. The lower half of the ROM resides in memory at FC0000-FFFFFF, the upper half is unused and unaddressable.
 
The very popular and inexpensive TL866A MiniPro Programmer was used here to program the TUTOR ROMs. Before attempting to program the ROMs with a TL866A check the following ...
 
App Software Ver: 6.85
Firmware Ver: 03.2.86
 
... and upgrade if necessary before proceeding.
