The third year will come soon.
Thanks mister Frank !
Hi, In my PC-1500 i had problems with the first TE-1507 version using Xicor memory.
It was impossible to write something in an unprotected X28HC256.
The Team1560 needs were to have a big system RAM and a place to test system ROM extensions.
Done ! The TE-1507 is now working with 2 RAM ICs and the R/W protection is done by jumper.
Here are some pictures the prototype :
This one, number 3, is reserved for…….. ? Stay tuned 😉
The release version should be available in one month.
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 !
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)
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 !
A special thanks to “W” for an incredible information about the NANFENG PC-1500A !
I copy here his message from my Guestbook :
Thank you again, “W”, to share this information with my readers !
Update : The NANFENG manuals are a set of 3
This PC-1500 is more than an updated version with huge memory amount and double-speed oscillator.
It’s one of the firsts samples of the A04 production.
Who owns a such collector version ?
Take a screwdriver and verify your PC-1500s 🙂
Thanks again to Lukas ZELLER for this gift.
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!
Do you need a power adapter for your PC-1500/CE-150 or IWS adapter ?
The requirements are :
– plug dimensions 5.5mm x 2.1mm
– Negative inside, positive outside
You can find matching power adapter on eBay for less than $3 shipping included.
Use the keywords : DC 9V 1A EU Negative inside
Many of us have dreamed of this device!
But his selling price was 800DM did not make him accessible to all budgets.
It was designed by “Ingenieurbüro Walter Speidel” and sold a few hundred copies. To my knowledge the IWS is the only video interface for Sharp PC-1500.
So the mysterious listing we had:
This peripheral offers the following features:
– Playback on TV with the resolution of 25×40 or 25×80 characters.
– Input / Output cassette
– Speaker Output
The save/load with the tape are faster than Sharp instructions.
It is accompanied by a user manual in A5 size.
All is correctly described, the new Basic instructions, the memory organization, except the schematics.
And there exist a 3 page correction to it :
It can connect directly to the PC-1500 but needs it’s only power adapter.
And to the printer :
Next time we will talk about hardware considerations…
