Hi experts.

Hoping that someone has some idea on this one. Bought an Acorn A7000 recently hoping to play some of my old 4th Dimension games (specifically Powerband, E-Type, Drop Ship and The Wimp Game). Disks look fine, access properly and will happily copy onto the HD but when I try to actually run them I hit problems.

The Wimp Game is fine (inasmuch as it runs - still as annoying as when I was tried running it as a 12 year old on my A3000). E=Type, Drop Ship and Powerband though both get 'stuck' with E-Type and Drop Ship complaining that it can't find 'loader' and Powerband saying that it can't write to memory.

Anybody got any ideas?

What processor is in the A7000? Some later machines are known to have issues (speed, cache, etc), for which there are patches. Can you give any examples of what the error text is?

Also do you know if you have RiscPC versions of the games or the original Arc ones? You'll have much greater chance of success with RiscPC compatible versions, since the A7000 hardware/OS is much closer to that of a RiscPC than the other Axxxx machines.

They're all the original Arc versions (rather than RiscPC versions). Is there anywhere that I can get the RiscPC versions (ideally for free)?

The error messages I get are:
E-Type: Goes to startup screen and then displays "File 'Logon' not found"
Powerband: Goes to startup screen and then displays "File 'Logon' not found at line 25830"
Drop Ship: Message box pops up saying "n't move your screen memory" (yes, it does chop the first word).

Don't know about the CPU. Popping the hood says that it's an Arm7500 Rev A - does this mean anything? Is it even the right info.?

Hmm. Probably you'll be better off with StrongARM versions or at least patches - a lot of the older games aren't directly compatible and need patching and tweaks. If you have access to Acorn User CDs (particularly AUCD10), there are a load there, although I'm a bit vague on what is freeware/shareware/abandonware these days. This 'Logon' error is a new one to me.

Logon error is probably an obey file doing a *L. or similar which would have been a *LOAD on older systems, but is obviously translating as *LOGON now.

It should be pretty easy to fix the obey/exec or BASIC programs issuing the *L. commands - just load them into Edit and modify.

However, anything that badly written may fall foul of any number of CPU/OS "gotchas" once it has *LOAD-ed the code and trys to run it!
