How much interest would you have in an Imlac PDS-1 reimplementation?
I was having a conversation with a chip designer just today.....

That would be really cool! I'd buy one (after I got my own working :)

Hi,
I think this PDP-8/X reimplementation using FPGA technology is
a really good piece of work AND it sets an example for something
that could be very useful in the classic computer hobby. Re-
implementations of PDPs, VAXen or other computers are one thing,
also new IO modules for old computers are another interesting
use are conceivable. Let's say one would build an OMNIBUS IDE
disk adapter, or a VAXBI refrigerator adapter so one could use
one's VAX 6000 for home automation :-). The disk adapters are
particularly interesting, since a time will come -- and it is
pretty much there yet -- at which it is about impossible to keep
old MASSBUS disks running, so having a MASSBUS to IDE card
might just come to the rescue.
Great work (seriously!)

That's right. For each part, there will come a time when there are no
more original, functioning instances. Our ability to continue the
tradition will then lie in our ability to put something else in their
place.

Indeed. However, what we should concentrate on **IMHO** is manufacturing
new parts according to the old designs (e.g., building an RP05 from
scratch) rather than grafting new technology onto the old (e.g., hooking
an IDE drive to a Massbus controller). It might not be feasible now for
some or most parts, but at some point between now and the advent of
Star-Trek-style replicators, it will. "PDP, 11/70, hot!"

There are a number of similar projects ongoing. One in particular I will
mention is to put a complete PDP-10 processor on an FPGA.
My image is a black box into which can be downloaded any processor
architecture allowing that processors software to be run. Of course the
processor is only one part of the picture I/O bings in a whole host of
new problems.

Why? It seems quite pointless, nearly tasteless, what with the VGA monitor.

Jeri Ellsworth will be speaking about the C=1 at VCF 5.0. She'll have the
prototype on hand and may even run a slide show through the data projector

Because it allows us to still be using Commodores and
hopefully repair any
future problems with open-source, current technology. It's not merely a
modern C64 anyway; it has a '816 core, SDRAM controller, SVGA output and
she's even talking Ethernet in the spec.
The day when sourcing a C64 becomes difficult is the day when finding VGA
monitors will be equally difficult. Besides, the way most C64 people use their
C64s is very dependent on all manners of hardware "features" which would make
any simulation quite a difficult task to accomplish.
OTOH, if you regard it as a new 65816 computer (which may happen to be C64
compatible in some ways), it doesn't seem to bad.

It will of course have its own native mode, and at least on the discussion
list there are many ideas for a new OS specifically for this native mode as
well.

Which she is still attempting to do, and so far with
success, even with
tricksy things like VIC-II badlines (for the untutored, this is taking
advantage of the VIC-II's DMA cycle every eighth raster line and tricking
it into new and different behaviours/timing).
I still don't see the point. It's just a hardware emulation (and a mess of
wires =) when you could just as well use the real thing.
Besides, I think the coolness factor fits more into
this project than the
practicality factor, n'est pas?
Agreed, but then I'd rather she'd put that effort into something which could
be put in or onto a real C64. Adding ethernet capability to my C128D wouldn't
be that objectionable. =)

How about CLIPS? That seems to be 65816 native and rather advanced at this
stage. The real limiting factor in that case is the C64 resolution. IOW, a
65816 with VGA graphics /and/ resolutions would seem like a nice little thing,
though I suppose it needs some kind of selling point, which would be the C64
compatibility.
Mind you, you said "'816 core"; does that mean that there isn't a real
65816
in there, just a FPGA simulation? The fact that it is supposed to have a slot
for a SuperCPU seems to indicate that.
