Quote from: GUNHED on 18:50, 05 May 21You're not really going to use 'fda' as indicator for drive 'a' ??
Quote from: OffseT on 14:51, 29 May 21That said, maybe "wrong" was not the good wording, "inappropriate" might have been a better choice.
Quote from: OffseT on 14:51, 29 May 211. updating ROM 7; which is directly possible on all CPC but the CPC6128 (which has to be fixed).
Quote from: GUNHED on 19:08, 29 May 21In Germany about 90% of the CPC6128 can replace ROM 7. I don't know much about other regions.
Quote from: Audronic on 01:45, 08 June 21Hi GunhedDoes that mean that there are hardware differences in the CPC6128's that will allow rom 7 to be Over Written ...
Quote from: GUNHED on 02:53, 08 June 21Exactly, there are different mainboards.
Quote from: PulkoMandy on 07:44, 08 June 21It is a very simple modification to add a switch to disable the internal ROM (or even install an alternate one directly inside the CPC).
Quote from: PulkoMandy on 07:44, 08 June 21I don't know about these CPC which could disable the ROM, as far as I know, no one has confirmed (I mean with logic analyzer testing on the ROM pins) if it is really disabled, or if it's active, but the X-Mass ROM is "stronger" and manages to send its own data on the bus (which could work, but is not so nice to the hardware).
Quote from: TotO on 08:52, 08 June 21I suppose that you want to say he X-MEM, as the X-MASS do not handle ROM. And the X-MEM ROM is automatically disabled when the CPC access the ROM7. In 2013, it was concluded that a bus contention using the Bryce Lower ROM has allowed to disable it on the mainboard MC00020G only. https://www.cpcwiki.eu/forum/amstrad-cpc-hardware/disabling-rom-7/
Quote from: TotO on 10:32, 08 June 21Anyway, ParaDOS works fine at ROM6 for my usage since a decade. Why not UniDOS?
Quote from: Audronic on 03:24, 08 June 21I was wondering ? Are your CPC6128's That allow rom 7 to be over written identified as Schneider or something else ?
