A few weeks ago i told you about a PC-1500 made in China but now both versions were made in China too. These are not the NANFENG but real Sharp. I think that the NANFENG was the first in this country and later Sharp decided to produce on his own brand.
Do you have mode informations ?
At the beginning of December Oscar Rysdyk, from Holland, contacted me after finding my site by Google.
He wanted to offer me his own first hand PC-1500.
This one was purchased in the united states by his father.
Lets examine this PC-1500…
Do you see the serial number on the last picture ?
It don’t have any metallic grey paint.
This is same for all USA models, i think.
Thank you very much Oscar for this gift !
Oscar, you’re a photographer ! These pictures are very nice.
Just after Christmas my friend CGH was at home for a “PC-1500 day”.
We have talked, tinkered and exchanged some machines.
I’m proud to present you this one : the oldest PC-1500 i know !
(Except his one with a lower serial number)
Externally there is no change, it’s a PC-1500.
And on the back the only difference is the serial number :
But let’s opening the machine :
It’s strapped like a A01 ROM. Uh… these straps are white ! The first time i see one like this.
We can see on the SC613128 IC that it’s a A01 ROM.
The biggest white strap is mine, to repair a memory access problem.
Do you see the diodes on straps ? First time too…
Ok, more ?
The display board version is F2025, the oldest i know.
And the mode exciting, the CPU board !
There is no board revision !!!
If some of you have similar PC-1500, please, contact me to compare boards versions. 😉
And if you don’t have… this is a new quest !
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.
