I remember that. I still have the Byte magazines Neat CPU, made for floating point operations if I
recall.

But it was micro programed with EPROMS. Nice idea.

hey, can u also fwd me a copy of the 'EGO' article ur
talking about. plss.......

Don't ask me, I don't have the access to BYTE anymore.
Sorry.

Thanks for the pointer. Obtained a copy just now from our library archive.
Hmmm, looking at it, it looks to me difficult to rebuild that thing, just
because many of the TTLs used there are now obsolete and hard to get
(this holds for the also mentioned "Computer 74" from Elektor magazine which
I have as well). Examples of such chips are (from the EGO), at a first glance:
74100, 74381, 74189
Particularly the latter is a problem, as it is also used in the SWTPC 6809
computer. I do know of the AM29701 as a replacement for it, but this is
also a scarce resource (bgmicro). Anyone has still sources (and not
unreasonably expensive) for 74S189 or 74F189?

A quick search on the web shows many venders offering
these parts for around $2 to $3/each. Don't know if
you consider that unreasonably expensive.

Sure. I already phoned several ones in Europe just to find
out that the internet is quite an unreliable reference:
"Yes, we didn't update the pages for some time...no, this
circuit is no longer in stock. But we could start a query
for you. How many hundreds do you need?"
Other companies that claim to ship worldwide apparently
don't consider Germany as part of the world (I guess they
extended the axis of evil a bit).
you consider that unreasonably expensive.
This would be okay. But take into account that it is not a really
good idea to order just a small amount of a particular circuit
as the S&H costs will be high. So, I'd rather order them together
with some other components that are just needed. Larger shops, e.g.
Farnell, RS Electronics, Jameco, to name a few, however, do no longer
have them, at least not or no longer stocked.
