PRELIMINARY PROM (and PNEW) MANUAL (February 13, 1980 7:19 PM)

There are two programs available to fuse proms’, one called PROM which drives the Alto Prom Blower (Blue Box), and the other called PNEW which derives PROLOG-92. PROM (as well as PNEW--- only PROM is mentioned thereafter, unless otherwise noted) combines the features of APROM, PROMDIAG, and LOGICPROM. . PROM runs in three modes, "MB File" mode which corresponds fairly closely to APROM, "MB File" mode which corresponds fairly closely to PROMDIAG, and "MB File" mode which corresponds fairly closely to LOGICPROM. Another promgram BINLIST is available for listing MB-files.

PROM COMMAND LINE

GLOBAL SWITCHES

string/PPermute memory address (Default ...,2,1,0)(use comma between pin numbers)
string/QPermute memory data (Default ...,2,1,0)(use comma between pin numbers)
string/RReverse prom’s address and/or output data (string: A and/or D)
name/FRead micro binary from file "name"
name/DWrite differences on file "name"
name/MUse memory "name"
number/T*prom ID number (see Table 2 for ID’s, "0" for WHATEVER)
[addressA,]value/W**value written into addressed locations, and checksum updated
0/IInvert the output data
number/N"number" exclusive or with the address
number/CChip starting address equals "number"
number/BSet chip starting bit equal to "number"
number/ASet memory starting address to "number"
number/SSet memory starting bit to "number" blow the prom.

* needed only in PNEW to identify prom type, if the prom is not in the list use "0". However, be awared that Command line using non-zero ID may be different from that of using zero ID due to differences in prom’s pin-assignments between the manufactures and ours (see Tables 3 and 4). For instance, the two slightly different command lines to fuse Intel 2708 are:

PNEW file/F memory/M 4/T proma/C promb/B mema/A memb/S

PNEW file/F memory/M 0/T D/R proma/C promb/B mema/A memb/S

** available only in PNEW, very special application. Address is a 16-bits address, value is a 32-bits numbers (address must followed by A and separated by a common from the value, octals are indicated by "R8" following the number or numbers, only one "R8" is needed). PNEW first slices value into four bytes (add leading zeroes if necessary) and write into four consective locations, from (address-5) to (address-2), of the memory, then modifies the checksum at the location address of the memory by adding four 8-bits numbers of the value onto it. Default address is #3777 if addressA is not supplied.

A command line of PROM is looking like this:

PROM file/F memory/M diffile/D promaddr/C prombit/B memaddr/A membit/S

where file is a file in micro-binary format (see appendix A of D0ASSEM, D0 Microprogram Assembler, by E. Fiala, for details on this format), memory is the name of a memory in that file, promaddr is the lowest address of this prom to be programmed (normally 0), prombit is the high-order bit of this prom to be programmed (normally 0), memaddr if the lowest address in memory to be programmed in this prom (frequently 0), and memibt is the highest-order bit of memory to be programmed in this prom (frequently 0). The idea is that bit membit of word memword of memory will be programmed into bit prombit of word promword of the prom, and so on, increasing in word number until running out of memory length or prom length. Words unspecified by the file are left unchanged.

If fifile is specified, then instead of being programmed, the prom will be checked against the appropriate part of memory. All differences will be written on diffile. PNEW requires prom-type to be supplied so that the prom’s characteristics will be varified with that of the Personal-card, the switch is "IDnumber/T". If the prom to be programming is not in the list (see Table 2), use "0/T", in which case the varification is bypassed. For other switches, please see Local Switches List above.

PROM reads its command line from left to right. All other switches but S simply set internal variables in PROM; whenever PROM encounters the S switch it attemp←ts to program a prom according to the most recent settings of its internal variables. For historical reasons PROM expects numbers to be decimal; octal numbers must be followed by "R8". The compare swich is (set by /D) retained once set, (so are I, N, R switches) hence no prom-programming after a prom-checking in the same command line. To compare a sequence of proms against a sequence of segments of a memory and concatenate all results onto one differences file, the name of the difference file should be specified with the first /D and omitted from each succeeding /D.

For example, if we had a file X13.MB with a memory called MicroCode declared to be 16 bits wide, and we wanted to put the low-order 4 bits of the second 256 words into a 256x4 prom, we might say

PROM X13.MB/F MicroCode/M 0/C 0/B 400R8/A 12/S

To program a set of 8 proms to hold the first 512 words of MicroCode, we might execute the following command:

PROM X13.MB/F MicroCode/M 0/C 0/B 0/A 0/S 4/S 8/S 12/S
256/A 0/S 4/S 8/S 12/S

The first prom generated by the above command would contain the high-order four bits (0-3) of locations 0-255 of MicroCode, the next would contain bits 4-7 of locations 0-255, and so on.

Talbes 3 and 4 show the pins assignments for the address and data-output lines. Please check them throughly. In case they do not match yours there are two ways to confirm your need, switch /R for reversing pin assignments, and switches /P (or /Q) for permuting address (data) pin assignments.

BINLIST is for listing MB-files:

BINLIST file/F memory/M identification/H Listfile/L

where Listfile is the name of listing output file. Other switches are Q, P, I, N (works same as in PROM), and Anumber/R (only for reversing address, number is the number of address lines to be reversed).
