ZEPROM (for HP-41) at Ebay ? Message #1 Posted by Ray Colle on 4 June 2004, 6:28 a.m. There are two GUNZEN Artillery HP-41 at ebay. They are still extremely cheap (28 bucks): http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=2247933429&sspagename=STRK%3AMEWA%3AIT&rd=1 and http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=2247933648&sspagename=STRK%3AMEWA%3AIT&rd=1 Does anyone know if they carry these extremely rare and valuable ZEPROM modules ? I think one GUNZEN normally carries two ZEPROM modules with 48 kByte total. Ebay value of one ZEPROM is 250 Euro I believe. One ZEPROM has 24 kByte of re-programmable Eprom placed in a normal ROM module. It can be reprogrammed by ZEPROM burner or by some guy (maybe Matias Werli or was it someone else?) who offers such a service to burn them. Thanks, ray Edited: 4 June 2004, 6:31 a.m.

A Gunzen only carries two simple ROMS (AFDC1F-MDP1, AFDC1F-MDP2, but no ZEPROMS. You are right, the Gunzen was also made by Zengrange, who built also the powerfull ZEPROM. You are also right that I can programm your ZEPROMS, but more than that I would like to get some more ZEPROMS... Does someone replaced his ZEPROM with a Clonix41 module and wants to sell me his ZEPROM? Matthias

Re: RE: ZEPROM (for HP-41) at Ebay ? Message #7 Posted by Ángel Martin on 4 June 2004, 9:37 a.m., in response to message #2 by Matthias Wehrli Interesting, I'm looking for the Zeprom *burner* (the little one) - how about trading it for Zeproms? (so neither one can ever have both together ;-) Best, ÁM

Re: ZEPROM (for HP-41) at Ebay ? Message #8 Posted by Ángel Martin on 4 June 2004, 9:40 a.m., in response to message #1 by Ray Colle Ray, As Matthias says the Gunzen has two 8k ROMS. What I'm not sure about is what *else* does it require to work properly. if you look at the FOCAL code, it's got calls to another ROM, with XROM id#31... Does anybody know? Best, ÁM
