One comment:  I have a 10 megabyte RD51.  Its capacity is 10 megabytes
only if you take a megabyte as ten million characters.  And CHKDSK would
not help much since I have the disk divided into MS-DOS and CP/M
partitions. WUTIL does give the size.  You can also do the calculation:
Multiply 306 tracks by 4 (the number of heads) by 16 (the number of
sectors per track) by 512 (the number of characters per sector).

I suggest we leave arguments about language and go back to my original
question:  Has anyone found a way to use the extra memory in the
Suitable Solutions' memory board for the Rainbow?

I had a similar problem when I tried to format a 20 megabyte hard disk
with the utility supplied with the DEC 10 megabyte hard disk.  But WUTIL
formatted the disk.  I suspect that the DEC-supplied hard disk utility
was not intended for disks larger than 10 megabytes.

You  might be interested in knowing that I have started using LZEXE.  It
reduced SEDT version 3.3(248) to a little over half its original size,
and the program seems (so far, anyway) to be working.  I also used LZEXE
in my own programming.  Verion 4.1 of my XTRAC utility lost thousands of
characters thanks to LZEXE

I wrote to Fabrice Bellard suggesting he produce a generic version of
his program (I happen to speak French).  I have had no reply, so I do
not know whether he will produce one.

Thanks for the upload, my clock works great and had been keeping almost
perfect time for the past several years in storage.  It also works
perfectly with DOS 3.1b and Code Blue I got just before suitable
solutions went out od business.  It properly date stamps IBM PCFILE+
 databases underCode Blue and is easy to reset.  Thanks again!!

   306 * 4 * 16 * 512 = 10027008. Am I doing something wrong?

    Given Warner Losh's posting on the subject, it sounds like we've
both been correct. As for your original question, I haven't. Question,
though, how many and what type of memory chips are on that board?
Would they be 1MBit chips per chance? My guess is some of that extra
memory is hidden from view by things like the Rainbow's video RAM,
which is located in segments EE00 - EF00 (952K - 960K).

    Based on his use of generic MS-DOS calls with PKZIP, maybe Phil
Katz will. Has anyone seen/used a beta copy of PKLITE? It is similar
to LZEXE but comes with docs/prompts in English.
