As you understand my research to tell the story of the PC-1500 does not have borders.
I have many things from Germany. And my previous donor, Xavier Fojud brought me a link between France, Germany and Switzerland. In the latter I already had some contacts but the documents he had generously offered allowed me to connect some names.

Last week I received a gift of Lukas ZELLER.
He has been active Swiss side of the PC-1500 with his diary “Tips & Knife” and his assembler ZASM-S.
So here is his generous gift:

– PC-1500 Expanded to 28KB of RAM + switch to activate a 4Mhz quartz.
– PC-1600 the first version with integrated memory expansion to reach 96Kb.
– CE-150 Printer
– Sharp software modules CE-510A, 502A and 505A
– CE-155 modules whose components were removed to tinker extension of PC-1600
– CE-162E interface
– PC-1500 Technical reference manual
– PC-1600 Service Manual version SME1
– 3 user manuals for software that I’m trying to get.
– 2 prototype cards for male connector.
– ZAMS-S user manual developed by Lukas.

These PC-1500 and PC-1600 contain something not trivial that I will reveal later here in the series of articles on Lukas Zeller.

A huge thank you to Lukas!
