MCODE: Card_Reader 1G ROM

[Ángel Martin]

Recently I've been looking into the Card_Reader 1G ROM to learn more about the section dealing with the HP-67 code conversion.

This ROM is a piece of work, fully packed and stuffed with tons of interesting tricks. Looking at the ROM contents it becomes clear that the Card_Reader was a difficult peripheral to control. I guess the breakthrough was the original models on with the HP-65 and 67, but the 41 implementation is a real masterpiece.

Anyway I was wondering if somebody had already disassembled the HP-67 code conversion part of the ROM, located at addresses E469 to E566 and E5A7 to E608. Those tables appear though to crack, I'd expect them to be some kind of mapping between HP-67 and HP-41 instruction codes but so far I haven't figured it out...

Best,
ÁM

I haven't looked at it in detail, but the fact that it's revision -1G implies that it was a challenge to get right.

Yep, so I'm now looking for the "HP-67 Byte Table"- if such a thing ever existed?
I seem to remember an article on PPC dealing with the HP-67 instruction codes, but again, it might be just a figment of my imagination...

My guess is that there must be a look-up table mapping 67-instruction codes to 41-byte_table values. Time for another wading session...

The initial HP-67 8-Bit Program Codes table appeared at the end of Louis Cargile's article, HP-67 Internal Codes and Quasi-Alphanumerics, from HP65 Notes Volume 4, Number 1, pages 5 - 8 (1977). Some of us remember Lou as the inventor of the HP-67 "Black Box", first described in 65 Notes V4N5 in his amazing article "Zen and the Art of HP-67 Maintenance", starting on page 4. Building that box was my very first soldering adventure :-)

Yeah, those names do ring the bell...many thanks for the information, will follow up shortly.

I can't believe its not GOT butter!
Is there really no commented source code for the Card Reader from HP ???

Angel, those spaces don't look like tables to me. To start with they only represent half the codes for the 67, also the codes that do fit are in higgledy-piggledy order - any responsible assembly table maker would have reduced the table order to 1,2,3,4... order. Next there doesn't seem to be any table addressing code in the whole of the card reader ROM, not even an offset address, by one or two bytes, i.e table 1 is at E469 so the search would be to look for an ld@ code having 9h as the last digit of a 4 digit address, but with an offset of a byte it would be 8h or if 16 bit offset it would be 7h, but none of these are apparent in the ROM. Its the same for the other table 2 at E5A7.
Its like the 1G updated version has some left over code that is not cleaned up from the previous version.
Just a few thoughts on the matter.

Hi Derek, thanks for chiming in. I'm half-way through the decoding of the tables, which I'm pretty sure there are active tables, even if decoding their logic requires more information than usually. (HP would not leave all that dead code there, it's MCODE heresy!)

For starters the table is exactly 256 bytes long, which provides a pretty good hint of its contents. Obviously one needs to follow the order defined by the HP-67 "byte table". Thanks to Thomas (and Eberhard) this was revealed to be the proper sequence of the words on the table starting at E467 (not at E469 as I first thought - thanks to Mike for that pointer as well).

As to the index or starting location, it's implicitly built in the call to the subroutine at E465: the call loads E467 in the return stack, from where it's picked up by the subroutine. The table offset (i.e. position to read) is expected to be in A.M on entry.

The logic fetches the word, and depending on the value of the XS nibble it interprets the word as :

a. if XS=0, a direct translation into an HP-41 byte code
b. if XS=3, one of the XROM id#'s from the card reader itself
c. if XS=1, the address of the location where the actual combination of instruction codes are to be found
d. if XS=2 - not clear yet....

All this is of very limited use since the HP-67 code cannot be read by the HP-41 directly unless thru the utilization of the card reader obviously - and separating it into an independent function doesn't seem to be very useful; it's just the challenge of course.

To be continued, this is just the beginning.

Thats OK Angel, I figured you might like the assembly-code insights, & you were red-hot with spying out the 2-byte offset to the table address. Even if its not in line-code that is readily readable.

The table looks like an ugly SOB, not something I would want to decode!

That brings me to the 2nd table, it doesn't seem have an E5A7 or an offset-E5A5 address in the ROM, that I could see?

I'll just wish you good luck with that one. DA

So here is a "quick writeup" of what I've been working on with the commenting the card reader mcode - diverting my attention to the 67 translation table rabbit hole.

Starting partway through the process of translation. Assume the 67 program is already read in, and now we need to translate it a byte at a time (according to the card reader manual, this is how it works), starting from the end of the program and moving to the beginning.

I love how the 41C engineers played with addresses, having one translation table at address 0xE467 (get it? For 67?) and the main translation code starts at 0xE567 ... another 67 address. And this is some intricate code using highly coupled code, data, and addresses.

Note: Names of the tables, translations, and code labels are all mine (and may change in the future).

Overview
--------------------
There are two translation tables and 5 different kinds of translation.

The two translation tables:
TABLE 1 at 0xE467 contains single word translation codes (TC) that are used to specify how to translate a 67 byte code (67BC) into one or more 41 byte codes (41BC). TABLE 1 is indexed by the 67 byte code.

TABLE 2 at 0xE5A7 is used to translate one 67BC into one or more 41BC that may require some processing of the codes found within. It is index by mcode that takes the TC from Table 1 (values 0x100-0x3FF) and turns it into an address into TABLE 2.

There are 5 different kinds of translation used (my naming):
SINGLE: This is a direct, one to one translation of a single 67 byte code into a single 41 byte code. This uses only TABLE 1. Let look at the LOG function as an example (67BC = 0x27, 41BC=056). Using the 67BC as an index into the table (0xE467+0x27=0xE48E), we get the TC value of 0x56. The translation MCODE sees that the value is between 0x000 and 0x0FF, so it knows it is a SINGLE translation (actually knows not to do a "multi" translation).

XROM: This is a one to 2-byte translation that takes a 67BC and translates it into an XROM call to a card reader function. The card reader is XROM ID 30, which gives 0xA780 - 0xA7A4 as XROM codes for its 36 functions. For TC values that are > 0x380, the code interprets the TC as specifying an XROM code. It does a "magical calculation" (see below) that extracts the last byte (0x080) and outputs that and an 0xA7.

EXEC: This is special translation that uses the TC to generate (same "magical calculation") an address in the card reader rom and then jumps to that address (using a GOTOC). This EXEC translation is used twice. The first is for translating the 67BC for CHS, which requires special code because the 41 actually has two byte codes for this: CHS as a unary operator, and NEG for data entry (and exponent). The second time is for the 67BC GTO 0 thru GTO E, and here the code just translates from a 67BC 0xD0-0xDE to a 41BC 0xB1-0xBF, and then outputs a 0x00 (for the jump count).

MULTI-A, MULTI-B: These are a one to many translation that uses the TC to generate (same "magical calculation") an address into TABLE 2 where a list of one or more words is found. MULTI-A alters the first word in the list, and then acts like MULTI-B. The list can be thought of as 41BCs that are output one at a time, until the 41BC has a value greater than 0x0FF (has a non-zero value in the high 2 bits). These MULTI translations are used for three purposes.
(1)for single 41 bytes that require "extra stuff" from the 67 version. For example, the statistic functions (S+, S- MEAN, SDEV) all translate to three bytes on the 41, because they have a SREG 14 prepended (to ensure the sigma registers are at the 67 equivilent location). Also, the 67 LBL A-Ea-e include not only a 41C LBL A-Ea-e, but also a numeric LBL 10-19.
(2) for multi-byte 41BCs, such as STO, RCL, SF, CF, XEQ, LBL etc. where the single 67BC must translate into 2 (or more) 41BCs. (Also the special nature of 67 flag 3 - similar to 41 flag 22 - is handled here).
(3) there is one case where an XROM is handled this way - the DSP0-9 translating to XROM 7DSP0-9.

THE MCODE
--------------------
We start around 0xE465. We have a 67BC in A:M (mantissa field of CPU A reg), and we do a GOSUB 0xE567 (TRANS67) to translate it. 0xE567 is going to get the TC from the table (CXISA), and then test the TC for greater than 0x0FF (is this not a SINGLE). If it is not a SINGLE, it calls 0xE609 (TROTHER) ... see below. Then (either a SINGLE, or the last translation of a XROM/EXEC/MULTI-A/MULTI-B), it calls 0xE637 (TROUTONE) to output one 41BC. Then it checks if we are at the beginning of the 67 program (remember, we are going from end to beginning). If not, we loop and do the next byte. If at the end, we output a LBL 67 as the first instruction in the 41 code. (Note that before we started - at 0xE458 - we output a GTO 67 as the last instruction).

The code at 0xE609 (TROTHER) handles all the non-SINGLE translations. All of these start out with the "magical calculation" that takes a TC, and turns it into an address. So a TC of 0xpqr, turns into either 0xE5qr or 0xE6qr. This address is used for XROM ... the qr becomes A7qr. For EXEC, the address is 0xE6qr. For MULTI-A or MULTI-B, the address is into Table 2 and is 0xE5qr or 0xE6qr. At the end of this calculation, we then repeatedly test and branch ... first testing the TC >= 0x380 (for XROM), then for >= 0x25F (EXEC), then >= 0x1C4 (MULTI-B) or else MULTI-A. And MULTI-A alters the first TC2, and then falls into MULTI-B. For all of these, if they generate n 41BCs, then they will output n-1 of them, and then return with the last one in C:X, which will be output by the caller as a SINGLE.

That's the "simple" overview. For more details, feel free to look at my code (source and listing files attached below). Please remember that this source is a work in progress ... I'm a long way from my goal which is commenting the entire 4K card reader rom. Feel free to comment or send suggestions.

                   1066 ;**************************************************************************​****
                   1067 ; * TRANS TABLE 1
                   1068 ; * Table of translation codes to convert from 67 byte codes into the 41 byte table.
                   1069 ; *     Translation codes (TC) are accessed by the 67 byte code (67BC) in A:X above (TR67LOOP)
                   1070 ; *     calling TRANS67, which gets the translation code from the table below,
                   1071 ; *     and then may call TROTHER to convert it to one or more 41 byte codes (41BC)
                   1072 ; *
                   1073 ; * Note 1: There is a second translation table (TRANS TABLE 2, see 0xE5A7 below) that
                   1074 ; *     is used for multibyte translation, and contains what I call TC2 values to distinguish
                   1075 ; *     them from the TC values in this table.
                   1076 ; *
                   1077 ; * Note 2: Multiple bytes (41BCs) are generated in REVERSE ORDER. This appears
                   1078 ; *     to be because the entire 67 program is read in, and then translated, so
                   1079 ; *     bytes are translated from end to beginning.  Because of this, mutliple 
                   1080 ; *     bytes in the TRANS TABLE 2, appear in reverse order, e.g. RCL 25 would
                   1081 ; *     appear as 0x19 followed by 0x290 (0x90 + 0x200 to end the sequence).
                   1082 ;*
                   1083 ; * Note 3: 67 Flag 3 is the data entry flag which on the 41C flag 22.
                   1084 ; *
                   1085 ; * There are 5 different kinds of translation, based on the TC itself:
                   1086 ; *
                   1087 ; * SINGLE      TC of 0x000 - 0x0FF
                   1088 ; *     Direct, one to one byte translation. E.G. 67 SQRT is 67BC 0x03 translates
                   1089 ; *     directly to 41BC 0x52. This is accomplished by having the actual 41BC
                   1090 ; *     located in the Translation table at 0xE467 + 67 code (0xE467+0x03=0xE46A).
                   1091 ; *     Since 41BCs are 0x00 to 0xFF, the code checks for TC's that have C:XS as zero.
                   1092 ; * MULTI-A     TC of 0x100 to 0x1C3
                   1093 ; *     This is a one 67BC to multiple 41BCs translation. The 41BCs are found in TRANS
                   1094 ; *     TABLE 2, and end with a 41BC that is greater than 0x0FF. Also, MULTI-A requires 
                   1095 ; *     manipulation of the first byte found in the table, but subsequent bytes are direct.
                   1096 ; *     This first byte manipulation is used (for example) to subtract out the 67BC so that
                   1097 ; *     a single TC2 value can be used to generate different 41BC values (example, 67BC )
                   1098 ; * MULTI-B     TC of 0x1C4 to 0x25E
                   1099 ; *     This is a one to multi byte translation that uses a table of multiple bytes
                   1100 ; *     that end with a +0x200 added to the last. No special extra manipulation.
                   1101 ; * EXEC        TC of 0x25F to 0x37F
                   1102 ; *     This translation requires microcode to execute to figure out what
                   1103 ; *     byte or bytes to translate into. Example is the 67 CHS, which on the 41
                   1104 ; *     can be a CHS (0x54) if standalone, or NEG (0x1C) if part of a number
                   1105 ; * XROM        TC of 0x380 to 0x3FF
                   1106 ; *     This translations inserts an XROM instruction from this ROM
                   1107 ; *
                   1108 ; * Note 4: MULTI-A, MULTI-B and EXEC do a "calculation" that changes the TC
                   1109 ; *     into an Exxx address, into either the TRANS 2 Table which will be accessed
                   1110 ; *     through a CXISA, or into an mcode address that occurs after the TRANS 2
                   1111 ; *     table that will be access by a GOTOC. That same "calculation" leaves the
                   1112 ; *     lease significant byte (nybbles 1 and 0) as is and basically prepends an E5
                   1113 ; *     or E6 in front. This is also used to get the second byte of the XROM
                   1114 ; *     translations (so a TC of 0x3A3 is "calculated" to E7A3, and then )

Great job Robert! many thanks for the detailed descriptions; time to delve in again but I think you pretty much covered all bases.

Fantastic!

LB_E781 is RSTKCA, 'rebuild the key reassignment bit maps' which also appears in the extended functions module.

Excellent! Thanks Håkan!

Can this go to Github (or similar site)? I am thinking that it would be good to have it one official location.

Suggest this be kept in the fan community; no need for excessive exposure, poking the bear.

I'd say TOS is the most logical and appropriate place to post it - that's probably where most folks would go looking for it as well.

Definitely it should also be in the articles section, where it won't be buried by all the forum activity.

Yes, both places are best as Angel points out; submit it to Warren and ask to have it added to the Library at TOS, but also add it in the Articles Forum here at MoHPC.

Happy to take a second swing at the "quick overview" and submit it to the articles here ... maybe as a pdf, and even to TOS.

Were you guys (thinking of me submitting the src/lst files as well? Even though they are very incomplete?

I'd say that if you're planning to work on it further, best to wait until you complete it, or get as far as you think you can, and then post it to both places; there's likely no urgent demand, just nice to have it in the places future fans are likely to look.

If it will be some time before completion, you might submit it now to TOS, the files (docs and src/lst files) can be easily updated with new versions when available. Articles here are more difficult to update, but you could always post an article now and later post another one, referencing the original.
