Beebug's Spellcheck 3, I think.

A LOGO rom for a Valiant Turtle or similar.

See below

Goes with Music 500(0)

Standard

Watford's Wordwise

AMX SuperArt.  Needs the AMX mouse and the support discs

>   [EPROM   2764] NLQ

Watford's Epson NLQ ROM which gets improved printing quality out of most
8-pin matrix printers (before NLQ printers with more needles in the
printhead became common)

>   [EPROM  27128] Advanced Teletext ROM 2.58

oo. 2.58?  Sure it's not 2.50?  That'll cause some excitement.

>   [EPROM   [2] ] ARM ADT

Advanced Disc Toolkit.  A debugger.  You need the manual and support
discs (I gave them to someone on the list years ago)

It's a 32k or 128k EPROM.  The carrier board has paging logic built in.
It won't work unless the hardware is duplicated 

>2 - This may or may not be for the BBC. It's an Intel EPROM marked:

Unusual markings.  I'd expect an Intel EPROM to be a typical 27128 or
similar. It'd have to be plugged in to see if it contains anything of
interest.

&8009 or &8012 (can't remember which) contains the ROM ID string if it
is for a Beeb.  It terminates in a chr$(0).

There are manuals for some of the above@...
