Re: [M100] REXCPM orders.

Steve:

Been busy with working nights since this COVID-19 mess started and guess 
I missed some of the REXCPM posts. I am another interested in a REXCPM 
4mb et al. No hurry as am in the middle of upgrading one of my other 
computers.


In trying to catch up with REXCPM info I didn't see anything about 
REXCPM vs DVI, or maybe I forgot where I might have read it. As is, 
would the REXCPM work with the DVI? I know there are a few conflicts and 
I have experienced some myself; e.g. SuperRom. Am thinking a REXCPM 
might work, but with a mod version of CPM to comunicate with the DVI?

Ah, I think I see now.  The REXCPM provides the BIOS, BDOS, and

of the CP/M stuff, and the Z80 upgrade only replaces the CPU, and
adds a
Z80 CPU, but no CP/M specific stuff.  Is that correct? Thanks!

NOT sold by me, but I thought some might like to know a NADSbox is for sale.

Hi Stephen,

How awesome.  I would love one, but, remember, I changed the Molex 
socket out for a standard socket when I was a trainee (many years ago), 
so I could plug other items into it.



I have sockets if you want to put an original socket back in.

Hi Bert,
in order to run ANY CP/M on M100, you need REXCPM.
The Z80 upgrade is "beta" and still being refined.   I plan to offer that
as a separate device.
So you could get started with REXCPM and then augment it with the dual
processor card.
make sense?

Hi Steve,

Is this the Z80 unit?  I'm interested in running Turbo Pascal (I already
have a Kaypro 2X to run it on but it's not exactly "portable" :-)
If this is the Z80 version then I'm definitely interested.  Thanks. :-)

Hi Chris,
gotcha.
Can you reach out off list with address info?
I guess you want a 2MB version for M100?

Hi James, the REX Wiki page has been updated, lots of info there- cheers

Re: [M100] REXCPM orders.

[Stephen Adolph]

Hi Eric, here are some answers-
REX# provides better mechanical mounting via the Molex adapter, and it
includes a redesign that improves reliability.  However, I am reducing
feature support and one of the removed features is main rom replacement.
Original REX uses flash, REXCPM uses SRAM.  Flash needs no backup power but
SRAM does.  SRAM is needed for CP/M operation.
cheers

Hi Steve

Where can one find info about the REXCPM? I feel like I stepped away  
from the computer and missed a huge chunk of development and  
discussion haha

Hi everyone,

Just a note to say I am ready to take orders for REXCPM!
Information is at the REX wiki.
Model 100 only for now.
2MB and 4MB available.
Pricing is USD excluding shipping.

Note:  REX# is delayed as is the VT100 adapter due to mailing  
delays from China.


Cheers

Re: [M100] REXCPM orders.

[Erik van der Tier]

Ah, I’ve just answered my own questions I think. The REX# is still flash based 
so does not need a capacitor to protect its memory.

I guess this leaves me with two questions; 
1. does the REX# still support main OS ROM replacement through hardware 
modification? (I haven’t done this yet, but was planning to).
2. Are there any immediate advantages of the REX# over the ‘classic’ other than 
continued support (which is quite a thing)?

I’m totally understand the reason for the end-of-life of the Classic REX line 
so this is definitely not an issue for me. I’m really mostly interested in 
what’s new and imrpoved :).

Cheers,
   Erik
