[cctalk] Re: Found the DSM orange manual

Hello,

As a MUMPS programmer, I would definitely be interested…  A former boss lent me 
his copy once. I should have scanned it.

Interesting thought.  I don't think I ever had to look for a layer 3 RPL
helper.  RPL seems to have fallen out of favor around the time IP took over
the world.

Sounds like a convoluted way to convert a HEX file into a binary file,
or whatever you mean by an EPROM friendly file. I imagine most EPROM
programmers can directly take an Intel HEX file as an input file.

If you needed a binary file, you could also use SRecord 1.65 srec_cat
to convert the Intel HEX file to a binary file, and split it up into
smaller chunks if you need to split the 8KB binary into smaller
EPROMs.

That's a good point, though like you I don't know of anything that ever
tried to take advantage of that theory (though I wouldn't have been paying
enough attention at the time to confidently comment, so...).  Since it's
not 'common knowledge' that it was done, I'd surmise either 1) the reality
is harder than the theory, or 2) it made more sense to wait for Intel chips
with less limitations, which seemed to me to be what was going on at the
time.  But certainly an interesting 'what if'.

[cctalk] Re: IMSAI BASIC PROM set?

2023-06-29 Thread Bill Degnan via cctalk
So I was able to get the listing for the PROMs by using the HEX file of
IMSAI BASIC 1.4 from.Rich Cini's website.  I was able to then pull the
Intel papertape file image using Teraterm to capture the log of the session
while using to load BASIC into the IMSAI.  I can use the log to make an
ePROM-friendly file.

Imsai 8K basic fills ..1FDB and stores programs from 2000, so you need
some RAM after IFFFh (8K).

My IMSAI has an IMSAI SIO serial card.

That setup was quite usual I think. We also have the 8" disk station from 
Infotek (alas, the interface module has been lost, I can't find it). It is 
stacked on top of the 9830 and below the printer.
We also have several peripherals, like HP the papertape reader, plotter, serial

[cctalk] HP2100A available

2023-06-29 Thread William Donzelli via cctalk
This is on Discord.

I have an HP 2100A with a paper tape punch (a HP labelled Facit), tape
punch (HP), and an 7900A disc. The thing is in decent shape - full of
cards. The keyswitch is out of the thing, but I am pretty sure I still
have it.

Right now, I have me hands on the 2100A and Facit paper tape punch
(with bracket) - can I get $1000 for this combo? When I get my hands
on the reader and 7900A ( I think they are just buried!), we can deal
with them later, as I do not like to sell what my hands are not on.
Located around Kingston NY.

Oh, I have a 5 foot rack for this thing, still back at the old house.

It's in the Imsai Basic manual as a choice for loading g the software.

I had the ROM set (8 proms) but I must have overwritten them a long time
ago.

So, I wanted to make a  new set, hoping someone had the eprom files avail
so I could make.

If not I will build a new setsome.other way.  Does anyone have the
papertape image of IMSAI basic 1.3 or 1.4?

The 730 does not have a PDP-11 as frontend. It uses the RB730 integrated 
disk controller with attachments for the RL02 and R80 drives.
The R80 provides 120MB of storage, enough for a small VMS installation. 
And as it's a Unibus machine, you can add more peripherals.
