Current Status of the Turbo-816:
The smaller version of the Turbo-816x is now at the board house, and
should be back in a few weeks.
The SRAM board is also out on the same order as the T816x boards, and
should be back about the same time. As soon as they get me the prices
I will put them up here.
Due to some noise problems when certian MIO units are connected to the
PBI interface, I am investigating various solutions. Initially
Bob Puff & I thought of a buffer board, but it ended up being to
difficult to manufacture, and Bob had limited success getting the
buffer board to work with non-t816 due to the additional propogation
delays. Another solution, which seems to work, is to add bypass
caps to certain lines.
add 100pf (pico-farad) bypass caps to the R/W line, Phase-2 line,
and see if that helps the problem, if not, try adding bypasses of
the same size to the data bus. as a last resort, the address bus.
these caps are usually very small, and if anyone finds a source
for SIP style, let me know.......

Version 1.1 of the Turbo-OS will become available this week. It is
now in the very final test stages, and only checksum balancing
needs to be done.
many improvements have been added, including a much superior memory-
management algorithm for the expanded memory type. also a better
test algorithm for extended (xe-banked) ram was added, resulting
in more banks available for >256k machines. A few minor bugs
that slipped past the beta testers were also corrected.
there are now approx 100 t816 installed world-wide. not a gangbuster
count, but considering the infancy of the project, not bad I feel.
Turbo-Calc is still being worked on.... a few minor problems popped
up, which are being looked at.
Alf-ASM for the T816 is being developed by Jeff Williams, and Bob Puff
and look for it to become available sometime within a month or two.
this asm will support all native mode op codes, and hopefully full
external/public module linking.

Now for the question. I'm not much of a hardware hacker, so could anyone
explain to me what the above MIO fix procedure amounts to? Thanx.
