Hi Folks,
TI-59/58 Diagrams !!!!
(I've also posted this message on the oddcalc list)
I've come accross an old schoolproject that "M.B. van der Mark" once
wrote. It details a lot about the TI59 hardware. The material is very old
though and cannot be scanned with good quality, it is also written
in dutch.
So I took it upon myself to revamp and translate this material. For
starters I made a new drawing of the TI59/58 schematic.
In the coming weeks (or month) I will add the diagrams for the
powersupply, the PC100 Printer .... and the abbreviated translation
of the rest of the material that details some of basics of operation
of this marvelous programmable calculator.
I will put this material on my website at
http://xgistor.ath.cx

It is a dynamic DNS though, so it can be down

You suspect right. Most cases where WIN9x has to reboot to keep
perfomance always seem to track back to a driver or app that never
"leaks" memory. More ram or more cpu cannot help that much.

Hi,
Does anyone know where I can find a Prolinea 4100 setup disk? Dozens of
those computers around but everybody seems to have thrown away the setup
disks.
Thanks in advance
Wim
We are trying to get an APC operational, and would like to ask if
anyone has a couple of the optional memory expansion boards that they would
part with for a reasonable price?
Also, does anyone know where I could track down a tape punch and
reader for a Model 33 Teletype?
Thanks

A good place to start.
FP4's will probably have PROM 4.1, or perhaps 4.1.2. You can manage
them from a DIRECTLY connected LocalTalk or EtherTalk (Phase I)
connected Mac running FastPath Manager (FPM). [This is also true for
FP2's or FP3's which were upgraded to 2U's or 3U's] FPM uses "KLAP" --
a packet with "LAP" type 0x4b (the letter 'K'), which cannot be
routed.
An FP4 could be upgraded in two ways; Just a new PROM (5.1), or a new
PROM, and a 256K SRAM memory board (for a total of 512K), which came
with a new case, and a fan. A box with PROM v5.1 can be managed with
FPM, or via Shiva Net Manager (SNM). SNM only speaks KLAP over DDP
(or was that ATP). DDP is the regular AppleTalk network layer, so you
can speak to boxes via intervening AppleTalk routers. ATP is the
transaction protocol, layered on DDP. The CPU clock on the FP4 68000,
was, I believe 8MHz.
FP5's started with PROM v5.0 [FP5's use their PROM only to load the
"VROM" -- a protected memory version of the PROM code]. FP5's came
with 512K standard, and could be built with (or, I suppose upgraded
to) up to 1MB, and the CPU clock was, I believe 10MHz.
The FP4 is perhaps, more flexible in the hands of a hacker, since you
could take direct control of the SCC, and do async or perhaps sync
serial. On the FP5, the SCC is part of the I/O Processor (a Zilog
Z181), and I never did an API to load code into the IOP. All versions
of the FastPath PROM provide a vector of routines which the download
can call. In PROM v4 and up, this includes access to the Ethernet
driver, which is how we got away with replacing the iNTEL Ethernet
controller from the FP1/2/3/4 with the Fujitsu EtherStar -- the
download (K-STAR) doesn't care what the hardware is (direct SCC and
i82586 on the FP4, or IOP and EtherStar in the FP5).
On powerup, the PROM spends 20(?) seconds flashing LEDs, then starts
the download, or the built in PROM GW (removed in v5), which is a
simple Phase1/LocalTalk router (with no IP capabilities). Its's best
to pause or reset the box before it gets rolling, in case it's
misconfigured or otherwise frotzed. Once you have it paused, you can
set the configuration and download K-STAR (NOTE!! With FPM and K-STAR
8+, the Phase II zone list is sent appended to the download, so it
only gets set when downloading code!! -- SNM can set the zone list any
time -- although the details of how we did that escape me at the
moment).
AppleTalk routing; If you set VERY LITTLE configuration, K-STAR will
autoconfigure, either learning information, or supplying it. If you
set some things, but not others, autoconfiguration may be disabled.
IP; Most people will probably want to use the box to IP-enable
LocalTalk Mac's. The simplest way is to use K-STAR IP, and supply
"dynamic" addresses. The Mac IP addresses will directly follow the
FastPaths, so assign a big enough block. MacTCP has an option
"dynamic", which you DO NOT want to use (it means randomly pick an
address to use!!) -- you want to use a "server" assigned address.
I can't (off the top of my head) think of any other pitfalls.

Don't be silly. My crystal set had a germanium diode, and I bet Allison's
did too :-)
I do remember my father buying a Philips Compact Cassette recorder when
they were new and even cooler than my 7-transistor radio finished in red
artificial leatherette. A cassette recorder of the same model still
happily reads and writes tapes on some of my older home micros, despite
being old when they were new (if you see what I mean).

I have three of the "old style" touch tone phones available (real bell, can be used with an acoustic modem),
If anyone wants them please let me know, we can work something out.

Thats the case. Most pizza boxen that are under 5" high have to mount the
card
horizontally so the do the 120 pin connector and riser with the cards
plugging into
the riser sideways.
I have a AT&T P100, Dell 486DX and Dell 386sx/16 all using risers like
that.
