hi,
my s4 will no longer load library off a ROM and store it. in mask mode it can load Eproms and do checksum but i can't get it do anything else. I thought perhaps the SRAM (32x8) chip was bad and replaced it but still exhibiting the same behaviour.
Does the library go on to the SRAM Chip?
thank you
S4 has stopped loading lib

Re: S4 has stopped loading lib
Hello obsoletemachines,
Thank you for posting in our user forum. The S4 library is not stored in the user RAM but in a transient program area, this means that the full capacity of the RAM is available to the user (128K or 512K). Please reference the S4 user manual for more details (Page 5): http://www.dataman.com/downloads/dl/fil ... manual.pdf
It could be poor contact that is causing the problem with loading the library, please try locking down the library ROM in the S4 ZIF and then using your thumbs to slide the chip from side to side, effectively scraping the ZIF contacts with the legs of the chip. This is usually enough to clean the contacts and get the library to load.
All of the S4 libraries and a full device support list are available from our website here: http://www.dataman.com/dataman-s4-resources
If you have any questions, please do not hesitate to contact me.
Best regards,
