Hello !

The TE-1507 memory module is now in my PC-1500 !
This module offers a very wide memory space for developers.

It was initially planned to have RAM and EEProm but due to a bad EEProm lot… it’s now full RAM.

Standard memory for Basic/ML :
– from &0000 to &3FFF
– 2 x 16KB switchable by PV or PU (jumper to select active signal)
– read only by removing a jumper
– disabled by removing a jumper

EEProm memory (here it’s RAM) for ML only as system/peripheral ROM extension:
– from &8000 to &BFFF
– 2 x 16KB switchable by PU (as in the CE-158 interface)
– set by jumper if it’s in the PV=0 (like CE-150) or PV=1 (like CE-158 or CE-162E) memory space
– read only by removing a jumper
– disabled by removing a jumper

The two memory addresses can be inverted by placing the enable jumpers on the switch positions (90° move)

Here are the pictures :

This module will be a very good investment to expand your PC-1500(A) !
The Team1560 member CGH is working on a ROM builder to add Basic keywords from a wide library. Cool, isn’t it ?

The price for this special module is $75 without shipping costs.
