The research behind our upcoming chipspeech product led us to develop a great interest on the different versions of the CPU and Speech ROMS (VSMs) that were shipped in the various revisions of the US speak and Spell. Earlier versions had bugs and a different word list than the final ones.

We (me and a few other researchers) so far have collected three different word list/roms for the main US Speak and Spell, but we feel there might be more than that out there.

We are looking specifically for the earliest "Buttons" versions that have date codes in 1978 and early 1979.
If you have one with a membrane keyboard, do not bother.

How to get the date code:

Whether or not it is circuit bent or broken makes little difference to us.
This is for research that will be published, not for inclusion in the software.

As an example an early Speak & Spell built-in word was removed in later releases for obvious reasons.

I'll let you guess what it really was.

Yes, it indeed  _sounds_ like freak, but that's not the word they encoded.
They recorded and encoded "SHRIEK", but LPC being what it is, out of context and 'blind' you can hear other things. smile

They have changed/removed/disqualified bunch of words this way, this is part of the story we want to document.

I used to have some and don't anymore, wish I did so I could help. This is awesome!

I have two "Buttons" unit so far. the problem is the date-code being relatively small and embossed, its hard to tell from eBay pictures alone. The best would be to get access to a first 'test' run unit.

mine is a homonym heros speak and spell made for nz and australia market
the date code is MTA0380

Thanks KIDD.
Interesting Item.  Does it have the British voice or the US voice?
(note: I Know Homonym Heroes is an US cart and as such has the US accent)

It's OK, if its a non-membrane SNS with Manuf date of anything in 1980, means its the mass produced bug fixed, standard 2x16KB Speech roms.
(note a bit later the membrane had only 1x16KB speech rom. thus roughly half of the number of built in words)


Thanks but still 1980, anyone else has a  1979 or 1978(best) unit?
