However groepaz pointed me to SAM, a nice little synthesised voice synth that is possible on the oric without vast changes so may integrate this in any Disk version. I have been meaning to have a look into SAM for a few years, but was told it may be hard to get to work on something inferior to what...

Re: Oric Speech Engine

[..] although it was synthesised speech it just acted upon the Commodore 64's SID 4 bit Volume register I think they all did. Some may have used frequency modulation or PWM to generate sampled sound at a higher resolution than the volume register can do. [..] the C64 has a variant of the 6502 as it...

Thanks for the bump. I have not made any further attempts to fix the keyboard, but perhaps I will try later this fall. Can one retrofit an Oric-1 with an Atmos keyboard? I think I've seen that once, looking quite freaky.

I thought the 6522 VIA and 6526 CIA were quite similar from a programmer's point of view. I know a couple of routines involving timers which should work on both, but perhaps the CIA has more control to offer than the VIA has.

If you want to optimize away the MaskCol table, I believe you can use something like this: lda #$80 looprow pha eor #$ff sta via_porta lda #$fd sta via_pcr sty via_pcr lda via_portb and #%11111000 ora row sta via_portb nop nop nop nop lda via_portb and #08 bne keydet pla lsr bne looprow skip: dex bp...

You're a brave man, defining 23 items on your to do-list. Usually I would be intimidated by seeing my own list, so I would only keep it in my head and forget half the stuff until a later day when I remember it again. :)

Great work! Compared to what many of us other "accomplish" in a year, missing out one night of retro coding is no big deal.

Oh, for those who have a recent copy of the High Voltage SID Collection installed, you can listen both to Impossible Mission, Beach Head II and Cave of the Word Wizard (see GAMES/A-F for the latter). I think all those and many more use the same speech technology. Actually I've been playing with the ...

"Another visitor, stay a while. Stay forever.." "Destroy him my robots." It would also be cool to do French translations of these sentences too. I always found the evil doctor speaks with a foreign accent, not sure from which country. Thus while it is relatively easy for someone...

If you use 11 kHz mono files, perhaps uncompressed WAV is good enough? Memory storage is cheap today, if you use a 2 GB MP3 player or better.

My first Oric-1 bought last year was sold as B&W, thus partly broken. I found out if I push something onto the knob on the top side of the RF modulator, I get colour. For a while I taped a piece of plastic onto it. I suppose replacing the RF modulator would be ideal thing to do. Even better if o...

For that matter, you could use one of the more advanced 6502 disassemblers to obtain mis-aligned source code of any program you like. It may turn out to be as much work to port a disassembled game as working with some kind of source code for an alien system. BTW, a lot of the MiniGame compo entries ...
