|

|

* Note that there is a Kana character 'I' in romaji on the end of the labels, not an I.
|
||||
|
||||
** Note this device was plastic and not ceramic, but it was dumped as a Harris 7641 as
|
||||
it is logical that its compatible with the 7641. I can see the other devices all have
|
||||
similar/same Harris markings in the bottom left of the IC obscured by the labels.
|
||||
|
||||
*** Note that the label for the 7643 PROM at IC25 was almost scraped off, but by its position
|
||||
in the sequence, it has to be 6H. I removed a little more of the label in order to
|
||||
work out what the inking was on it below, turned out to be 'D-2'. the prom at IC22 also
|
||||
looks like it has an inked number under the paper label, just peeking through on one side.
|
||||
Without removing the paper labels entirely, these markings wont be fully known, but were
|
||||
covered for some reason.
|
||||
|
||||
SPECS:
|
||||
|
||||
- CPU is an NEC D8085A
|
||||
- Crystal is marked 6.1440, but this looks to have been replaced.
|
||||
- X1/X2 clock frequency measured at pins 1 + 2 is 6.14330 mhz
|
||||
- Test point with stable readings is :
|
||||
- TP4 (HS) = 15.9982 khz (Horizontal sync)
|
||||
- TP5 (VS) = 60.5992 hz (Vertical Sync)
