Dave,

I did Fined where I got it. and also noted that it also uses FLAG 4 not 3.

Im Not Sure Where You Got Your TB-Mon Code. But The One that I Have
Was Set Up to use 1000 As Begining ram Page, But I Can't fined where
I got it. I Looked At The lay out of your computer an noted it uses
an 8K rom which would put the ram starting a 2000 the code would have
to be changed.

Looking for parts to make P-E Elf

erd_6502 <erd_6502@yahoo.com>
 

I'm in the middle of a year at the South Pole. For fun, I brought
with me as many of the parts for a P-E Elf that I could find in my
junk box. I think I have 90% of what I need (I didn't bring the HP
displays with me, but I have some TIL311s), but I'm still looking
for a few parts...

Does anyone know the physical dimensions or part numbers for the
switches? How about for the dry-transfer letters? I have a box
of machined-pin sockets with me (solder-tail, not WW, but I'm
going to do it point-to-point anyway), but I don't have a source
for 22-pin sockets for the 1822 SRAMs... does anyone know where
to secure a few of those?

I have three 1802 chips with me, as well as enough support chips
to have some fun. I can get some C&K paddle switches from BG Micro,
but they don't look the same (plus, they are a bit stiff for
heavy use). BG Micro has some toggles that look like the right
thing for $0.80 each, but I can't really tell from the picture
in the catalog. If I knew more about how they are supposed to look,
I can probably verify things before I order.

Things take so long to get here that I'd rather get the parts in
a single order.

Thanks,

Fiddling with MSI88/e

 

Hello all,

I've been playing with the MSI88/e this weekend, using Lee Hart's
partial reverse-engineered schematics from the FILES section.

Looking at these, it seems that EF3 and Q are wired to the port in a
way that could support a bit-banged serial interface. It so happens
that Lee has also written the code for that in his IDIOT/4 monitor,
which comes complete with TMSI tiny BASIC.

I assembled the TMSI BASIC source, configured for 8K ROM (PAGE=2000H),
with SEQ/REQ reversed (to account for the inverted buffering of Q),
and using EF3 instead of EF4. The goal is to explore the unit
interactively via a terminal. I can see valid serial data from the
remote terminal on pin 22 (EF3), but no activity on Q. I did remember
to fill the unused ROM with FF to keep the startup code from trying to
execute a ROMed basic routine. I

To try to isolate the problem, I also tried a little program:

0000 36 05 LOOP B3 QOFF
0002 7a REQ
0003 30 00 BR LOOP
0005 7b QOFF SEQ
0006 30 00 BR LOOP

(At my programmer, I couldn't remember the code for SKP)

Again, no terminal echo, and no activity on Q, despite clock at pin 1
and valid logic signalling at EF3.

Interestingly, I notice that after powerup, the clock doesn't seem to
start up until the right-hand switch on the display board is toggled.
Forcing a reset by pulling pin 3 (CLR) low has no real effect.

It sure would be nifty to get one of these little buggers up and
running :-) Anybody have any insights, corrections, or suggestions?

Thanks,

Dave

ILASSEM.zip IL Code Development Package Online

richardep20002000
 

If you have already downloaded Tinybasi.zip From the Emulators
Directory. Please Redownload as This Has Been Updated.

If Not I Suggest You download this First As It will Make The Directory
Tinybasi on your hard drive. Please Only set the drive letter for
the unzip. Example C:&#92; Or D:&#92; and read the readme.txt document.

Then download the ILASSEM.zip File In the BASIC Folder And unzip to
TINYBASI directory, Then Read Notes.txt.

This is OLD DOS Programs, So Let Me Know about Problems Getting It To
Run. Some New Machines Do Not Support The Old Screen Resoution That
I used with Tinybasi.exe. If All Else Fails Boot Computer to DOS
Mode. I Have Ran This Program On An Old 386 laptop.

Hope To See Some New IL Code Soon!

Richard

You should check out Tom Pittman's Tiny BASIC Experimenters Kit

Near the end is the compiler for Tiny BASIC that runs under Tiny
