or do you know the common password on his site,, I have built the ZX1541 and need the firnware P file to burn the eeprom.. thanks,,,
I think that you can use the ROM dumped that comes with the VB81_XUR. Attached is copy just in case that you like to try it.
BTW: That would be great to see some pictures of your ZX1541

also thanks for the file .. but I need the P. file to run on the Timex 1500 I have and it will write to the EEPROM.. with the ZX1541...
I will post some pics a soon as I can.. I also have the IECATA which is really for the C< 64/128's but it can be accessed with the ZX1541 as a DIsk drive ,, it uses a IDE hard drive or a Compact flash card,, i use an adapter and a CF card.. works really great...I have a ZX1541 I bought already assembled,, but I bought blank boards from Jarek a while back and am just now getting it assembled..
However if you are using the older 1.1 version then I believe your entry point is actually 8192 not 12300. I think I have V1.2 installed in my ZX81 (machine is packed away at present), and there are two .p files available for that, one with the 12300 entry point, and the other with 8192. I use the 8192.
I have attached the zip file for the 1.2 version which includes the following:
ZX15412.ASM - source of 1.2 version that has 8192 entry point
ZX15412.P - file to load into ZX81 to upgrade (8192 entry)
ZX15412.TXT - readme file
ZX15412A.P - file to load into ZX81 to upgrade (12300 entry)
ZX15412.ROM - file to fill 28C64 (both 8192 and 12300 entries)
Hope this helps

I first got my ZX81 as a Kit in 82 or 83 .. After building it worked first time.. I then built an interface I saw in a MAG. it had A whopping 13K with some 6116 sram...Spending hrs Typing in prg's from mags.. I still have the 13K interface..
Hey what a great system.. looks very professional! everything nice and neat...
DID you build your ZX5141.. ? I still havn't go the one I built working prpoerly yet (using the 28C64 from the working ZX1541)... when you enter Rand Usr 12300 the screen just rolls and wiggles,,,
Can load the .p file using the 1541 you already have, then save it to tape, then reload it on your other setup?
Unfortunately I have just moved apartments so all my stuff is in boxes, otherwise I could probably help more. If I can find the box with my PC laptop, maybe I still have my .wav file there. I'll look once the rest of the family wakes up.
